Braking parts 50 is made up of the regenerative braking portion (not shown) of pressure brake (not shown) and/or motor, makes golf cart 10 stop according to the automatic Pilot under the brake pedal operation of driver or automatic driving mode。
Driving control portion 30 is the component that control golf cart travel speed and steering direction travel with overall control golf cart 10 under automatic driving mode or manual drive pattern。Under manual drive pattern, accelerator pedal or steering wheel are handled the traveling controlling golf cart 10 by driver by driving control portion 30, and under automatic running pattern, driving control portion 30 can be controlled golf cart 10 and travels along the induction coil 80 detect by inductive transducer portion 60 or along the magnet array pattern traveling detected by the magnet array mode treatment device 100 of the present invention。
The magnet array mode treatment device 100 of the present invention is to detect the magnet (70_1 to 70_n) buried underground under road and determine the magnet array pattern relevant with the polarity of magnet and magnet appearance order, and is correspondingly generated, with the magnet array pattern determined, the device controlling the control signal that golf cart travels。
The driving model of golf cart 10 includes manual drive pattern and automatic driving mode。The driver that manual drive pattern is golf cart 10 handles the pattern that the self-contr ol golf carts 10 such as control wheel, throttle and brake travel。Automatic driving mode is unrelated with the manipulation of the driver of golf cart 10, is automatically control the pattern of traveling by the various control devices of assembling on golf cart 10。Golf cart 10 is must bury induction coil 80 underground below the road of ball track with the precondition that automatic driving mode travels。
Induction coil 80 is to be easy to the coil buried underground under the ball track that golf cart 10 travels in golf course construction。Golf cart 10 is controlled and detects induction coil and travel along induction coil 80, and therefore induction coil 80 departs from ball track when being possible to prevent golf cart to travel under automatic driving mode。Described induction coil 80 buries into string underground under the central ground on ball track road。

Fig. 2 is the block diagram of the signal mode process device 100 of the present invention。
According to Fig. 2, the signal mode of the present invention processes device 100 and includes magnet sensor 110, signal analysis portion 120, control signal generating unit 130 and arrange storage part 140, additionally can include velocity measurement portion 150。
Magnet sensor 110 detects at least one magnet buried underground under road the detectable voltage signals that the polarity of generation and each magnet and intensity change accordingly。
Fig. 3 is the diagrammatic illustration of the detectable voltage signals generated at magnet sensor 110。
X-axis express time change in Fig. 3, y-axis represents the voltage output value of the detectable voltage signals generated at magnet sensor 110。
Golf cart 10 from magnet pass over time magnet sensor 110 can detect the magnet being embedded in underground。Output normal voltage when magnet sensor 110 magnet is detected, but magnet makes voltage rise or reduce and output detections voltage signal after being detected。When magnet is N pole, magnet sensor 110 exports the detectable voltage signals reduced than normal voltage, and when magnet is S pole, magnet sensor 110 exports the detectable voltage signals risen than normal voltage。
The time point below voltage of detectable voltage signals changed by normal voltage is called change time point, golf cart 10 from magnet through and away from after the time point of detectable voltage signals voltage returns normal voltage be called reply time point。It is called turnaround time from change time point to the time replying time point。It is called fluctuating margin to replying the maximum that in time point, detectable voltage signals rises or falls from the change time point of detectable voltage signals。
It addition, multiple magnet can be buried below ball track underground。A high point or low spot in detectable voltage signals are corresponding with a magnet respectively, occur the high point with number of magnets respective numbers or low spot when therefore golf cart is by plural magnet in detectable voltage signals。
First low spot occurred in Fig. 3 is because voltage reduces the magnet that can be identified as N pole, and second high point is can be identified as the magnet of S pole because voltage rises。Below in the detectable voltage signals of each magnet, the time difference between the change time point of each detectable voltage signals is called through recognition time。That is, refer to through recognition time and from certain magnet is detected voltage start moment of change voltage starts the time difference of the moment of change to next magnet is detected。
Return again to Fig. 2 below illustrate。
Signal analysis portion 120 analyzes the detectable voltage signals relevant with each magnet and whether judges useful signal, and determines the polarity of each magnet and the magnet array pattern of appearance order according to the detectable voltage signals being judged as useful signal。
Storage part 140 is set and stores the control signal corresponding with magnet array pattern, and store for eliminating arranging turnaround time, arranging fluctuating margin, arrange limiting distance and arrange through recognition time of detectable voltage signals noise。
Control signal generating unit 130 is to implement to compare with arranging the magnet array pattern of storage on storage part 140 by the magnet array pattern determined by signal analysis portion 120, and the magnet array pattern that generation and signal analysis portion 120 are determined controls the control signal that golf cart 10 travels accordingly。
As above shown in [table 1], arranging storage part 140 and store the traveling control model of the golf cart corresponding with each magnet array pattern, therefore control signal generating unit 130 can generate according to arranging the control signal arranging value control golf cart 10 traveling of storage on storage part 140。
It addition, signal analysis portion 120 includes effective judging part 121 and array pattern determination section 122, adjustment portion 123 additionally can be included。
Effective judging part 121 is the component filtering out insignificant detectable voltage signals and eliminating detectable voltage signals noise, it is possible to include timing judging part 1211, voltage judging part 1212 and Distance Judgment portion 1213。
Timing judging part 1211 is to analyze the time of the detectable voltage signals relevant with each magnet and eliminate the component of detectable voltage signals noise。Timing judging part 1211 measure the detectable voltage signals relevant with each magnet from the change time point risen or fallen by normal voltage to the time replying time point and the turnaround time of again replying normal voltage, the turnaround time of measurement is judged as useful signal in the predetermined detectable voltage signals arranged within the scope of turnaround time。If the turnaround time measured is too short or oversize and is not arranging within the scope of turnaround time, then this part can be judged as that this part is processed as noise by invalid signals by timing judging part 1211。
Arranging turnaround time is can determine in upper and lower 10% scope of such as 150ms, and the time range now arranging turnaround time can between 135ms to 165ms。Arrange and be not limited to described illustration turnaround time, it is possible to be decided to be suitable value according to the speed of golf cart and surrounding enviroment。
Voltage judging part 1212 is to analyze the voltage pulsation amplitude of the detectable voltage signals relevant with each magnet and eliminate the component of noise in detectable voltage signals。The detectable voltage signals relevant with each magnet is only exceeded the predetermined detectable voltage signals arranging fluctuating margin increase or minimizing and is judged as useful signal by voltage judging part 1212。If the fluctuating margin of detectable voltage signals not can exceed that arranges fluctuating margin, then voltage judging part 1212 judges that this part is invalid signals and processes this part as noise。
Fig. 2 illustrates maximum voltage and the minimum voltage that arranges of arranging, maximum voltage is set and the minimum voltage that arranges refers on the basis of normal voltage by arranging the value that fluctuating margin increases or reduces。In the example of Fig. 2, when being N pole such as magnet, voltage judging part 1212 only detectable voltage signals is judged as useful signal when dropping to minimum setting below voltage, and when being S pole such as magnet, only detectable voltage signals is increased beyond and maximum is judged as useful signal when arranging voltage。
Distance Judgment portion 1213 eliminates the component of noise with the difference of the spacing of each magnet of detection。Magnet is buried underground at regular intervals, the magnet therefore buried underground if any two or more, then magnet is detected first can dope the distance that next magnet is buried underground later。
The golf vehicle speed measured at velocity measurement portion 150 described later is provided to Distance Judgment portion 1213, and therefore namely Distance Judgment portion 1213 can calculate the distance the magnet corresponding with the first detectable voltage signals and the magnet corresponding with the second detectable voltage signals through recognition time according to the time of the change time point from the change time point of the first detectable voltage signals to the second detectable voltage signals。
Only the spacing of two magnets reaches predetermined when arranging more than limiting distance, the detectable voltage signals detected later can be judged as useful signal by Distance Judgment portion 1213, and the detectable voltage signals detected later is judged as invalid signals less than predetermined when arranging limiting distance by the spacing of two magnets。Arranging limiting distance is can be decided to be suitable value according to the interval of burying underground of magnet, it is preferable that buries about the 2/3 of interval underground with magnet and arranges。
It addition, Distance Judgment portion 1213 can utilize detectable voltage signals judge detectable voltage signals whether useful signal through recognition time。Only after recognition time, detecting that the second detectable voltage signals is just judged into useful signal by the change time point of the second detectable voltage signals from the first detectable voltage signals change time point first detected to predetermined arranging for this Distance Judgment portion 1213。Can determine to arrange through recognition time divided by the golf vehicle speed that velocity measurement portion 150 is measured by the aforesaid limiting distance that arranges。
Velocity measurement portion 150 is to be assemblied on the driving axle of golf cart 10 for measuring the component of golf cart travel speed, and the travel speed of measurement is provided to signal analysis portion 120。
Being typically under automatic driving mode golf cart 10 constant speed drive, therefore signal analysis portion 120 should arrange turnaround time based on golf cart 10 normal speed under automatic driving mode, arrange fluctuating margin, arrange limiting distance and arrange and be advisable through recognition time。But, when the speed of golf cart 10 changes, detectable voltage signals detects the fluctuating margin of detectable voltage signals of magnet, turnaround time, may change through recognition time etc.。
Therefore adjustment portion 123 changes according to golf cart 10 travel speed measured and arranges on storage part 140 arranging turnaround time, arranging fluctuating margin, arrange limiting distance, arrange the value of this change is supplied to effective judging part 121 after recognition time of storage。
Additionally, arrange storage part 140 to store respectively and corresponding with each speed of golf cart arrange turnaround time, arrange fluctuating margin, arrange limiting distance, arrange through recognition time, adjustment portion 123 can by by with turnaround time is set, fluctuating margin is set, limiting distance is set, the arranging and form in the way of recognition time is supplied to effective judging part 121 of the golf cart speeds match measured。
Array pattern determination section 122 is analyzed and is judged as that the part of useful signal determines the magnet array pattern relevant with the polarity of each magnet and appearance order by effective judging part 121, and the magnet array pattern of decision is supplied to control signal generating unit 130。
Array pattern determination section 122 is analyzed and is judged as that all detectable voltage signals of useful signal judge the polarity of magnet by effective judging part 121 till golf cart stops completely, remembers the polarity of each magnet and appearance order and determine magnet array pattern when multiple magnet being detected。
The magnet array pattern determined at array pattern determination section 122 is implemented to compare to generate the control signal matched afterwards by control signal generating unit 130 with arranging the magnet array pattern of storage on storage part 140。The control signal generated is provided to the driving control portion 30 of golf cart 10, and the driving control portion 30 of golf cart 10 controls golf cart 10 according to control signal and travels。
