Definitions
- the present application generally relates to navigation methods and devices.
- Navigation devices were traditionally utilized to provide services in vehicles or even on foot, for navigating between two points. Such devices, when used in vehicles, often initially tried to plan a fasted route based upon, for example, a route including mostly highway usage. Such a route was planned to maximize vehicle speed during travel along the route.
- the data upon which the traffic information was calculated was often gathered from the tracking mobile devices themselves. Although movement of mobile phones could be monitored, it was often difficult to determine if a moving mobile phone was present on a walking/running pedestrian, on another moving vehicle not present on the roadways such as a train for example, etc. As such, the traffic information calculated from this information and later supplied to the navigation device was often not accurate.
- the inventors discovered that if more accurate data regarding vehicle speed, vehicle slow downs and other data for calculating traffic conditions is supplied, then more accurate information can be provided to the navigation device regarding current traffic conditions. As such, the inventors developed a system and method to obtain data from navigation devices themselves, to more accurately calculate traffic condition.
- a method includes connecting a navigation device, located in a vehicle, to a server; transmitting information relating to changes in position and speed of the vehicle to the server; and receiving information, relating to potential delays along a route of travel of the vehicle, from the server, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles.
- a navigation device includes a modem to connect a navigation device, located in a vehicle, to a server; a transmitter to transmit information relating to changes in position and speed of the vehicle to the server; and a receiver to receive information, relating to potential delays along a route of travel of the vehicle, from the server, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles.
- a navigation device includes means for connecting a navigation device, located in a vehicle, to a server; means for transmitting information relating to changes in position and speed of the vehicle to the server; and means for receiving information, relating to potential delays along a route of travel of the vehicle, from the server, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles.

- the GPS incorporates a plurality of satellites which work with the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.
- the GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

- the spread spectrum signals 160 continuously transmitted from each satellite 120 , utilize a highly accurate frequency standard accomplished with an extremely accurate atomic clock.
- Each satellite 120 as part of its data signal transmission 160 , transmits a data stream indicative of that particular satellite 120 .
- the GPS receiver device 140 generally acquires spread spectrum GPS satellite signals 160 from at least three satellites 120 for the GPS receiver device 140 to calculate its two-dimensional position by triangulation. Acquisition of an additional signal, resulting in signals 160 from a total of four satellites 120 , permits the GPS receiver device 140 to calculate its three-dimensional position in a known manner.

- The present application generally relates to navigation methods and devices.
- Navigation devices were traditionally utilized to provide services in vehicles or even on foot, for navigating between two points. Such devices, when used in vehicles, often initially tried to plan a fasted route based upon, for example, a route including mostly highway usage. Such a route was planned to maximize vehicle speed during travel along the route.
- During such travel, however, a vehicle would often encounter traffic delays, which would slow travel along even a route including mostly highways. Accordingly, navigation devices became more sophisticated and were able to receive information and to utilize the information to plan navigation routes around the traffic delays. Such information was calculated and received, for example, via a mobile phones as will be explained as follows.
- In known systems for providing such traffic information, the data upon which the traffic information was calculated was often gathered from the tracking mobile devices themselves. Although movement of mobile phones could be monitored, it was often difficult to determine if a moving mobile phone was present on a walking/running pedestrian, on another moving vehicle not present on the roadways such as a train for example, etc. As such, the traffic information calculated from this information and later supplied to the navigation device was often not accurate.
- The inventors discovered that if more accurate data regarding vehicle speed, vehicle slow downs and other data for calculating traffic conditions is supplied, then more accurate information can be provided to the navigation device regarding current traffic conditions. As such, the inventors developed a system and method to obtain data from navigation devices themselves, to more accurately calculate traffic condition.
- In at least one embodiment of the present application, a method includes connecting a navigation device, located in a vehicle, to a server; transmitting information relating to changes in position and speed of the vehicle to the server; and receiving information, relating to potential delays along a route of travel of the vehicle, from the server, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles.

- In at least one embodiment of the present application, a navigation device includes means for connecting a navigation device, located in a vehicle, to a server; means for transmitting information relating to changes in position and speed of the vehicle to the server; and means for receiving information, relating to potential delays along a route of travel of the vehicle, from the server, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles.

FIG. 1 illustrates an example view of Global Positioning System (GPS), usable by navigation devices, including the navigation device of embodiments of the present application. Such systems are known and are used for a variety of purposes. In general, GPS is a satellite-radio based navigation system capable of determining continuous position, velocity, time, and in some instances direction information for an unlimited number of users. - Formerly known as NAVSTAR, the GPS incorporates a plurality of satellites which work with the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.
- The GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.
- As shown in
FIG. 1 , the GPS system is denoted generally byreference numeral 100. A plurality ofsatellites 120 are in orbit about theearth 124. The orbit of eachsatellite 120 is not necessarily synchronous with the orbits ofother satellites 120 and, in fact, is likely asynchronous. AGPS receiver 140, usable in embodiments of navigation devices of the present application, is shown receiving spread spectrumGPS satellite signals 160 from thevarious satellites 120. - The
spread spectrum signals 160, continuously transmitted from eachsatellite 120, utilize a highly accurate frequency standard accomplished with an extremely accurate atomic clock. Eachsatellite 120, as part of itsdata signal transmission 160, transmits a data stream indicative of thatparticular satellite 120. It is appreciated by those skilled in the relevant art that theGPS receiver device 140 generally acquires spread spectrumGPS satellite signals 160 from at least threesatellites 120 for theGPS receiver device 140 to calculate its two-dimensional position by triangulation. Acquisition of an additional signal, resulting insignals 160 from a total of foursatellites 120, permits theGPS receiver device 140 to calculate its three-dimensional position in a known manner. -

navigation device 200 is located within a housing (not shown). The housing includes aprocessor 210 connected to aninput device 220 and adisplay screen 240. Theinput device 220 can include a keyboard device, voice input device, touch panel and/or any other known input device utilized to input information; and thedisplay device 240 can include any type of display screen such as an LCD display, for example. In at least one embodiment of the present application, theinput device 220 anddisplay device 240 are integrated into an integrated input and display device, including a touchpad or touchscreen input wherein a user need only touch a portion of thedisplay device 240 to select one of a plurality of display choices or to activate one of a plurality of virtual buttons. - In addition, other types of
output devices 260 can also include, including but not limited to, an audible output device. Asoutput device 260 can produce audible information to a user of thenavigation device 200, it is equally understood thatinput device 240 can also include a microphone and software for receiving input voice commands as well. - In the
navigation device 200,processor 210 is operatively connected to and set to receive input information frominput device 240 via a connection, and operatively connected to at least one ofdisplay device 240 andoutput device 260, via connections to output information thereto. Further, theprocessor 210 is operatively connected tomemory 230 via a connection and is further adapted to receive/send information from/to input/output (I/O)ports 270 via a connection, wherein the I/O port 270 is connectible to an I/O device 280 external to thenavigation device 200.

navigation device 200 includes aninternal modem 290, connected toprocessor 210 andmemory 230, for establishing data connections as will be described hereafter. Themodem 290 may further be connected totransceiver 300 for transmitting information to and receiving information fromserver 302. Thetransceiver 300 is further connected toprocessor 210. - The

Thereafter, through its network service provider, the mobile device can establish a network connection (through the internet for example) with aserver 302. As such, a “mobile” network connection may be established between the navigation device 200 (which can be, and often times is mobile as it travels alone and/or in a vehicle) and theserver 302 to provide a “real-time” or at least very “up to date” gateway for information. - The establishing of the network connection between the mobile device (via a service provider) and another device such as the

According to at least one embodiment of the present application, both theserver 302 andnavigation device 200 include a transmitter for transmitting data through the communication channel and a receiver for receiving data that has been transmitted through the communication channel. - The
communication channel 318 is not limited to a particular communication technology. Additionally, thecommunication channel 318 is not limited to a single communication technology; that is, thechannel 318 may include several communication links that use a variety of technology. For example, according to at least one embodiment, thecommunication channel 318 can be adapted to provide a path for electrical, optical, and/or electromagnetic communications, etc. As such, thecommunication channel 318 includes, but is not limited to, one or a combination of the following: electric circuits, electrical conductors such as wires and coaxial cables, fiber optic cables, converters, radio-frequency (rf) waves, the atmosphere, empty space, etc. Furthermore, according to at least one various embodiment, thecommunication channel 318 can include intermediate devices such as routers, repeaters, buffers, transmitters, and receivers, for example. - In at least one embodiment of the present application, for example, the

navigation device 200 may be provided with information from theserver 302 via information downloads which may be periodically updated upon a user connectingnavigation device 200 to theserver 302 and/or may be more dynamic upon a more constant or frequent connection being made between theserver 302 andnavigation device 200 via a wireless mobile connection device and TCP/IP connection for example. For many dynamic calculations, theprocessor 304 in theserver 302 may be used to handle the bulk of the processing needs, however,processor 210 ofnavigation device 200 can also handle much processing and calculation, oftentimes independent of a connection to aserver 302. - The
mass storage device 312 connected to theserver 302 can include volumes more cartographic and route data than that which is able to be maintained on thenavigation device 200 itself, including maps, etc. Theserver 302 may process, for example, the majority of the devices of anavigation device 200 which travel along the route using a set of processing algorithms. Further, the cartographic and route data stored inmemory 312 can operate on signals (e.g. GPS signals), originally received by thenavigation device 200. - As indicated above in

Further, thenavigation device 200 can also include anyadditional input device 220 and/or anyadditional output device 240, such as audio input/output devices for example. -
FIGS. 4A and 4B are perspective views of an actual implementation of an embodiment of thenavigation device 200. As shown inFIG. 4A , thenavigation device 200 may be a unit that includes an integrated input and display device 290 (a touch panel screen for example) and the other components ofFIG. 2 (including but not limited tointernal GPS receiver 250,microprocessor 210, a power supply,memory systems 220, etc.). - The
navigation device 200 may sit on an arm 292, which itself may be secured to a vehicle dashboard/window/etc. using a large suction cup 294. This arm 292 is one non-limiting example of a docking station to which thenavigation device 200 can be docked. - As shown in
FIG. 4B , thenavigation device 200 can be docked or otherwise connected to an arm 292 of the docking station by snap connecting the navigation device 292 to the arm 292 for example (this is only one example, as other known alternatives for connection to a docking station are within the scope of the present application). Thenavigation device 200 may then be rotatable on the arm 292, as shown by the arrow ofFIG. 4B . To release the connection between thenavigation device 200 and the docking station, a button on thenavigation device 200 may be pressed, for example (this is only one example, as other known alternatives for disconnection to a docking station are within the scope of the present application). - The
navigation device 200, in at least one embodiment, may establish a “mobile” network connection with theserver 302 via a mobile device 400 (such as a mobile phone, PDA, and/or any device with mobile phone technology) establishing a digital connection (such as a digital connection via known Bluetooth technology for example). Thereafter, through its network service provider, the mobile device 400 can establish a network connection (through the internet for example) with aserver 302. As such, a “mobile” network connection is established between the navigation device 200 (which can be, and often times is mobile as it travels alone and/or in a vehicle) and theserver 302 to provide a “real-time” or at least very “up to date” gateway for information. - The establishing of the network connection between the mobile device 400 (via a service provider) and another device such as the
server 302, using the internet 410 for example, can be done in a known manner. This can include use of TCP/IP layered protocol for example. The mobile device 400 can utilize any number of communication standards such as CDMA, GSM, WAN, etc. - As such, an internet connection may be utilized which is achieved via data connection, via a mobile phone or mobile phone technology within the
navigation device 200 for example. For this connection, an internet connection between theserver 302 and thenavigation device 200 is established. This can be done, for example, through a mobile phone or other mobile device and a GPRS (General Packet Radio Service)-connection (GPRS connection is a high-speed data connection for mobile devices provided by telecom operators; GPRS is a method to connect to the internet). - The
navigation device 200 can further complete a data connection with the mobile device 400, and eventually with the internet 410 andserver 302, via existing Bluetooth technology for example, in a known manner, wherein the data protocol can utilize any number of standards, such as the GSRM, the Data Protocol Standard for the GSM standard, for example. - The
navigation device 200 may include its own mobile phone technology within thenavigation device 200 itself (including an antenna for example, wherein the internal antenna of thenavigation device 200 can further alternatively be used). The mobile phone technology within thenavigation device 200 can include internal components as specified above, and/or can include an insertable card, complete with necessary mobile phone technology and/or an antenna for example. As such, mobile phone technology within thenavigation device 200 can similarly establish a network connection between thenavigation device 200 and theserver 302, via the internet 410 for example, in a manner similar to that of any mobile device 400. - For GRPS phone settings, the Bluetooth enabled device may be used to correctly work with the ever changing spectrum of mobile phone models, manufacturers, etc., model/manufacturer specific settings may be stored on the
navigation device 200 for example. The data stored for this information can be updated in a manner discussed in any of the embodiments, previous and subsequent. - In an embodiment of the present application, a method includes connecting a
navigation device 200, located in a vehicle, to aserver 302; transmitting information relating to changes in position and speed of the vehicle to theserver 302; and receiving information, relating to potential delays along a route of travel of the vehicle, from theserver 302, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles. - In an embodiment of the present application, a
navigation device 200 includes amodem 290 to connect anavigation device 200, located in a vehicle, to aserver 302; atransmitter 320 to transmit information relating to changes in position and speed of the vehicle to theserver 302; and a receiver 322 to receive information, relating to potential delays along a route of travel of the vehicle, from theserver 302, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles. - Thus, in an embodiment of the present application, mobile phone technology located within the
navigation device 200 itself can include amodem 290, either located internal to thenavigation device 200 or external thereto, such as in an adapter for example. Further, a SIM card (enabled for GPRS data traffic for example) can be included in thenavigation device 200 to allow themodem 290 to connect to theserver 302. The Murcia Network Interface Protocol covers the steps and stages of Start-up Protocol, network selection, network connection, IP Address selection, VPN establishment, data-transfer, and network disconnection. It also covers the rules associated with, and in order to determine modem to network actions. - As such, a connection between the
navigation device 200 and theserver 302 can be established upon powering on of thenavigation device 200. - In an embodiment of the present application, once the
navigation device 200 is purchased and turned on, a data (e.g. internet) connection between themodem 290 andserver 302 is established to permit receipt of information relating to potential delays along a route of travel of a vehicle housing the navigation device 200 (such as traffic information for example) from theserver 302. However, as the data connection is established with theserver 302 in such an automatic manner, theserver 302 can thus receive information relating to changes in speed and position determined in the navigation device 200 (for example, the processor 2 10 of thenavigation device 200 can detect position from received GPS signals and can calculate vehicle speeds from GPS positions, map location information, and time traveled between positions, and can store such information periodically inmemory 230 for example) from a plurality ofnavigation devices 200. Thus, information may be transmitted from thetransmitter 320 or received by the receiver 322 of thenavigation device 200 in an initial start-up sequence with a device type code, as part of the connection established by themodem 290 between thenavigation device 200 and theserver 302. - Thus, the
server 302 can thus perform calculations regarding potential delays along travel routes using more accurate data, although the calculations themselves are generally performed in a known manner. The traffic delay information received by thenavigation device 200 will be more accurate, as it is being determined based at least partially upon information relating to changes in position and speed and transmitted from a plurality of navigation devices of a plurality of vehicles (the vehicles housing the navigation devices 200). As such, an efficient system for collecting better and more accurate data, from which traffic or other information relating to potential delays along a route of travel of a vehicle housing thenavigation device 200 can be calculated in a known manner inserver 302. - Connection is an automated process, beginning at start-up of the
navigation device 200, and controlled through a piece of low level code that selects the strongest network signal after referencing a control list. This is called the white list, and is a list of “allowed’ networks stored in themodem 290, and part of the Network Interface Protocol. As such, a network addresses for network connection is established. The second part of the process is using the data from a plurality of navigation devices to obtain better traffic information using algorithmic traffic calculations. This process is an off-board process, not calculated on thenavigation device 200, but rather fed to the device OTA fromserver 302. The addition of the new data elements directly from the “known” navigation devices becomes an addition to the algorithm to theserver 302 in adding certain signal sets, and eliminating false vehicle markers. - Compatible GPRS modems to most commercial available GPRS, CDMA, TDMA, or analogue modems may be used as
modem 290, with the following example characteristics, to include the capability of two way data transfer, with simultaneous data Input Output, On-Board RAM, and digital signal acquisition: - TriBand or QuadBand modems to follow below geographic Frequency guide:
- 850 MHz (In America)
- 900 MHz (In Europe and many parts of Asia)
- 1800 MHz (In Europe and Asia)
- 1900 MHz (In America)
- The calculation of traffic or other information relating to potential delays along the route of travel of a vehicle housing the
navigation device 200 is only as good as the data collected. As previously stated, known systems exist such as that of U.S. Pat. No. 6,650,948 to Atkinson et al issued Nov. 18, 2003 for example, the entire contents of which are incorporated herein by reference, which monitor information (and provide information relating to potential delays to navigation devices along routes of travel of vehicles housing the navigation devices) relating to changes in speed and position of mobile phones for example which, at times, may be located in places other than cars such as on planes, trains, and other vehicles not related to traffic congestion (see also U.S. Provisional application ______, entitled “System For Generating Traffic Information” and filed on Oct. 26, 2007, the entire contents of which are incorporated herein by reference). - In an embodiment of the present application, however, the data collected by the
server 302, from which the traffic or other information relating to potential delays along the route of travel is determined, is collected from navigation devices (in place of or in addition to the mobile phone information) such asnavigation device 200 for example, located within a vehicle housing thenavigation device 200, wherein such a vehicle is directly related to such traffic or potential delay conditions. By using amodem 290 within thenavigation device 200, or external thereto in an adaptor of thenavigation device 200 for example, information relating to changes in position and speed of the vehicle in which thenavigation device 200 is located, can be transmitted to theserver 302. Theserver 302 can then receive information relating to changes in position and speed transmitted from a plurality of vehicles, and can thus utilize better information (alone or in combination with other information collected from mobile phones as discussed above) from which to build more accurate traffic models to aid in determining potential delays along a route of travel of the vehicles housing thenavigation device 200. An example of a known system for obtaining information and building traffic modules by determining vehicle slow downs and stoppages in conjunction with map location information is that of U.S. Pat. No. 6,650,948 to Atkinson et al issued November 18, 2003 for example, the entire contents of which are incorporated herein by reference. - Mathematically, adding “known” elements (data from “known” navigation devices) to a pattern equation increases reliability of data accuracy. By eliminating an unknown device type and replacing it with a known device type, an uncertain is removed and is replaced with a certain. This has a double effect on a signal calculation, reducing variance by eliminating different use types (speed and location information of mobiles on trains, pedestrians, bicycles and therefore unrelated to vehicle traffic as was previously obtained from mobile device information) and increasing a core set of “known” devices (known to directly affect vehicle traffic congestion), with a category of use to reference; a test set.
- The information transmitted from the
transmitter 320 of thenavigation device 200 may be useable by theserver 302 to identify thenavigation device 200, to identify intended vehicle usage and vehicle type based upon the identifiednavigation device 200, and/or to increase at least one of mathematical accuracy and reliability in the information received by thenavigation device 200, relating to potential delays along the route of travel of the vehicle. For example, the information transmitted from thetransmitter 320 may be useable to determine a category type of thenavigation device 200. The category type of thenavigation device 200 may include at least one for commercial usage, consumer usage, motorcycle usage, and/or pedestrian usage. - The information transmitted from the
transmitter 320 may further be useable by theserver 302 to determine traffic patterns and potential delays along the route of travel of the vehicle and/or to improve defining of traffic behavior, to further determine traffic patterns and potential delays along the route of travel of the vehicle, and/or to aid the navigation device in providing a revised route of travel based upon the received information. Further, the information transmitted from thetransmitter 320 may further be useable to determine traffic behavior and expected flow patterns with enhanced accuracy and predictive methods, due to increased signal node identification for example. - In an embodiment, the
navigation device 200 may attempt to establish a GPRS connection, for example, using themodem 290 as soon as thenavigation device 200 is switched on and/or connected to a power supply through an adaptor. Network connection to theserver 302 can be provided via the SIM card, inserted into thenavigation device 200 to establish network addresses for network connection of themodem 290 for example. Network Connection may be an automated process following data stored for this process on themodem 290 itself, which contains information that can be updated in a manner discussed in any of the embodiments, previous and subsequent. - Such a SIM card and
modem 290 are shown inFIG. 5 , within thenavigation device 200. The SIM card can be provided to the user in exchange for fees for subscribing to a traffic service for example. By default, if themodem 290 is internal to thenavigation device 200, themodem 290 may always be enabled and/or if included in an adaptor of the navigation device, may be enabled upon the adaptor being connected to the vehicle. - In an embodiment of the present application, the traffic and/or information relating to potential delays along the route of travel of the vehicle may be transmitted by a
server 302 and subsequently received by anavigation device 200 periodically. The periodic receipt of this information can be, for example, every three minutes. - Information may be sent/received via
modem 290 andtransceiver 300 wherein packets of data are sent /received to the IP address directed by IP Address is stored on themodem 290, in code, as part of a protocol. This protocol knows if thenavigation device 200 is a TomTom Work device user (Commercial) or a TomTom PLUS device user (Consumer), based on a piece of code written to the SIM card. In theinitial navigation device 200 Start-up, themodem 290 reads the SIM for this code, and “sets” the navigation device type. From this, thenavigation device 200 becomes a Commercial or Consumer navigation device, and thus uses a specific IP address of either. As a whole, this is part of the Network Interface Protocol. - The information transmitted from the
transmitter 320 of thenavigation device 200 may be useable by theserver 302 to identify thenavigation device 200, to identify intended vehicle usage and vehicle type based upon the identifiednavigation device 200, and/or to increase at least one of mathematical accuracy and reliability in the information received by thenavigation device 200, relating to potential delays along the route of travel of the vehicle. For example, the information transmitted from thetransmitter 320 may be useable to determine a category type of thenavigation device 200. The category type of thenavigation device 200 may include at least one for commercial usage, consumer usage, motorcycle usage, and/or pedestrian usage. Once the Network Interface Protocol connection between thenavigation device 200 and theserver 302 is established, as part of the Protocol, the connection may be identified with a device type. - The
modem 290 may be, for example, dual integrated for both GPS and GPRS. By establishing a constant connection between thenavigation device 200 and theserver 302, via themodem 290 for example, information can be transmitted from thenavigation device 200, such as information relating to changes in position and speed of a vehicle, to theserver 302 at a time the same as or different from receipt of the traffic or other information relating to potential delays. Thus, data can be collected by theserver 302 at any time during the aforementioned periodic interval; and can further be collected multiple times during the aforementioned interval. - Further, once the connection between the
navigation device 200 and theserver 302 is established (via initiation by theserver 302 for example), information may either be transmitted from or received by the navigation device 200 (this can be done during times other than times of periodic receipt by thenavigation device 200 for example), wherein the connection may be established between amodem 290 within anavigation device 200 and theserver 302, and/or within an adaptor of thenavigation device 200 for example. - When the
navigation device 200 is powered, such as via an adapter or when the device is turned on for example, this initiates an automated Initiation protocol that themodem 290, with the corresponding SIM card, start an Network Interface Protocol. Searching for available networks stored on a White List—Listings of allowed networks—themodem 290 will find and select the appropriate network. Further, the SIM card (enabled for GPRS data traffic for -example) will transfer account and settings information to the network, establishing an IP Address, stored in themodem 290, and start a Virtual Private Network connection withserver 302. TheModem 290, SIM card and Network Interface Protocol (Network authoring code) can be included in thenavigation device 200 to allow themodem 290 to connect to theserver 302. Thenavigation device 200 will request information stored on theserver 302. A Communication line (a “connection” between thenavigation device 200 and the server 302) is established, (via initiation by theserver 302 for example), and data is thereafter transferred. - During the aforementioned interval, at times other than the specific times when traffic information or other information relating to potential delays is sent to and subsequently received by the
navigation device 200, requests for information uploads can be sent from theserver 302. Thus, information may be transmitted from thenavigation device 200 based upon requests for information uploads from theserver 302, during times other than times of periodic receipt. - The
navigation device 200 is capable of multiple connection settings. In a common setup, two setting types are pre-installed into thenavigation device 200; Commercial and Consumer. In a Commercial (TomTom Work) setting, signal accuracy, and signal availability are the primary considerations and as such modem behaviors relate to maintaining these connection parameters. In a Consumer (TomTom PLUS) setting, service availability is the primary consideration and as such the modem behavior relates to maintaining these connection parameters. - Specifically, in an embodiment of the present application, a connection is always on, initiated in a startup sequence of the
navigation device 200 as explained above and Part of a Network Interface Protocol. GPRS is capable of two-way communication, and as such two-way data transfer is possible, and in some cases desirable. For example if thenavigation device 200 is transferring location information to theserver 302, simultaneously theserver 302 could send updated traffic information tonavigation device 200. In this case, two way data transfer is necessary to maintain Traffic signal upload intervals, and traffic information download accuracy, and thus maintains updated route traffic information. Alternatively, the transfer of data can be done at different times, such as periodic or times of upload requests initiated by theserver 302 for example. - Within the
navigation device 200, a route of travel of the vehicle can be determined byprocessor 210 for example, based upon at least a desired destination (such as one input by the user of thenavigation device 200 for example) and a current location of the vehicle (such as that determined by a GPS/GPRS receiver within thenavigation device 200 for example). Thereafter, subsequent to receipt of information relating to potential delays along the route of travel by the vehicle, aprocessor 210 within thenavigation device 200 can determine a revised route of travel based upon the received information.FIG. 6 illustrates a display screenshot of thenavigation device 200 displaying not only a route of travel of the vehicle, but also displaying a traffic bar (located on the right part of the screen ofFIG. 6 ) to inform the user of traffic incidents along a planned route.FIG. 7 illustrates a subsequent display screenshot, including displays of both a particular traffic delay in the lower left corner ofFIG. 7 , and the display of other icons, including one for minimizing traffic delays. Upon selection of such an icon, the above-mentioned determining of a revised route can occur viaprocessor 210 for example. Thus, adisplay 240 of thenavigation device 200 can display an indication of potential delays along the route of travel of the vehicle, subsequent to thenavigation device 200 receiving the information relating to potential delays along the route of travel of the vehicle, wherein theprocessor 210 is useable to determine, upon receiving a request, revised route of travel based upon the received information in a known manner. - In an embodiment, the
navigation device 200 can includememory 230 to store information relating to changes in position and speed of the vehicle, wherein the stored information may subsequently be transmitted from thenavigation device 200 upon themodem 290 establishing a connection to theserver 302. Alternatively, the information relating to changes in position and speed of the vehicle may be stored, such that the stored information may then be transmitted from thenavigation device 200 upon establishment of the connection upon receipt of a request for information upload from theserver 302 Within thenavigation device 200, specifically stored onModem 290, This is an automated process based on a preset upload interval, this determines the upload activity intervals, as well as connection failure protocols. - For example, based upon at least a GPS/GPRS signal available current location, information relating to changes in position and/or speed of the vehicle can simultaneously be transmitted from the
navigation device 200 to theserver 302, based on time intervals controlled by themodem 290. In the Commercial settings, an active transfer rate can be, for example, every 60 seconds, with 6-10 second captures of position and/or speed of the vehicle. In an idle mode, for example where the vehicle has not moved for certain time such as 30 minutes for example, this interval may drop, to 5 minutes for example. Idle mode is intended to conserve GPS/GPRS data traffic, and thus reduce terrestrial data costs. - In either event, in such an embodiment, the information may be collected and stored within the
memory 230 of thenavigation device 200, for subsequent transmission to theserver 302. For example, themodem 290 and SIM card of thenavigation device 200 may provide only limited, or no available data usage over a network, and as such, the aforementioned transmitting of information relating to changes in position and/or speed of the vehicle and a current location of the vehicle (such as that determined by a GPS/GPRS receiver within thenavigation device 200 for example), will be stored at preset intervals to be transmitted when data usage over a network is available again. If network coverage is unavailable for a duration, thenavigation device 200 can includememory 230 to store information relating to changes in position and/or speed of the vehicle and a current location of the vehicle untilmemory 230 is no longer available. Thus, in at least one embodiment of the present application, the navigation device can include amemory 230 to store information relating to changes in position and speed of the vehicle, a display to display an indication of potential delays along the route of the vehicle and to display revised route of travel if calculated, as well as a processor to determine a route of travel of the vehicle and to determine a revised route of travel based upon received information relating to potential delays along the route of travel of the vehicle. Data may be stored in intervals explained above, in a specific order and string structure set by the TT Work Module for example (This should be described in the TT Work Patent submissions). - In at least one embodiment, upon determining a periodic interval for sending information relating to potential delays along the route of travel of the vehicle to the
navigation device 200 from theserver 302, information relating to changes in position and/or speed of the vehicle can simultaneously be transmitted from thenavigation device 200 to theserver 302. For example, themodem 290 and SIM card of thenavigation device 200 may provide only limited data usage over a network and as such, the aforementioned transmitting of information relating to changes in position and speed of the vehicle to theserver 302 can be coordinated and timed with synchronized or simultaneous receipt of information related to potential delays along the route of travel of the vehicle, by thenavigation device 200. As such, thenavigation device 200 andserver 302 can be synchronized to transmit and receive information at the same time over the established network connection. Again, during the interval between periodic sending and receiving of information, the information can be stored and collected in thenavigation device 200. - The
navigation device 200 of at least one embodiment expressed above may be implemented as a method including connecting anavigation device 200, located in a vehicle, to aserver 302; transmitting information relating to changes in position and speed of the vehicle to theserver 302; and receiving information, relating to potential delays along a route of travel of the vehicle, from theserver 302, the received information being determined based at least partially upon information relating to changes in position and speed transmitted from navigation devices of a plurality of vehicles. The method can include, in at least one embodiment, determining a route of travel of the vehicle, based upon at least a desired destination and a current location of the vehicle; and determining, subsequent to receipt of the information relating to potential delays along the route of travel of the vehicle, a revised route of travel based upon the received information. The method can further include, in at least one embodiment displaying an indication of potential delays along the route of travel of the vehicle, subsequent to receipt of the information relating to potential delays along the route of travel of the vehicle; and determining, upon receiving a request to calculate a revised route of travel, a revised route of travel based upon the received information. Additionally, the method can include, in at least one embodiment, storing information relating to changes in position and speed of the vehicle, wherein the stored information is transmitted from the navigation device upon establishment of the connection and upon receipt of a request for an information upload from the server. - Further, the method of at least one embodiment expressed above may be implemented as a computer data signal embodied in the carrier wave or propagated signal that represents a sequence of instructions which, when executed by a processor (such as
processor 304 ofserver 302, and/orprocessor 210 ofnavigation device 200 for example) causes the processor to perform a respective method.
