Description of drawings
Fig. 1 is the embodiment diagram of circuit of vehicle light control method of the present invention;
Fig. 2 is the structured flowchart of the OBD system embodiment of the invention process vehicle light control method.
The specific embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, embodiments of the invention provide a kind of vehicle light control method, and it may further comprise the steps S1-S6.
S1, utilizing the GPS(Global Positioning System in the OBD system, global positioning system) device obtains the current geographical location information of vehicle;
In one embodiment, the geographical location information here comprises longitude and latitude information.
S2, according to the OBD system acquisition current time;
S3, judge according to geographical location information and current time that vehicle is current and be in daytime or night;
The embodiment that comprises longitude and latitude information according to above-mentioned geographical location information, this step specifically comprises: according to longitude and latitude information obtain corresponding at sunrise between and sunset time, the current time that step S2 is obtained with at sunrise between compare with sunset time; If the current time the same day at sunrise between and between the sunset time, judge that then vehicle is in daytime; If the current time the sunset time on the same day and second day at sunrise between between, judge that then vehicle is in night.
S4, read the state of the current front car light of vehicle by the OBD system;
In one embodiment, the state of front car light comprises open mode and closed condition.
Vehicle is current to be in daytime if S5 draws through judgement, and front car light is open mode, then utilizes OBD system closing front car light; Vehicle is current to be in night if draw through judgement, and front car light is closed condition, then utilizes the OBD system to open front car light;
Vehicle is current to be in daytime if S6 draws through judgement, and front car light is closed condition; Perhaps, vehicle is current to be in night if draw through judgement, and front car light is open mode; Then the OBD system keeps the state of headlight.
Can be got by above-mentioned steps S5 and S6, if front car light is opened by day, perhaps front car light is closed at night, and then the OBD system carries out reverse correction operation to front car light, so that front car light is in suitable state.Otherwise if front car light is closed by day, perhaps front car light is opened at night, represents that then the state of front car light is suitable, thereby the OBD system does not carry out any operation and keeps its current state front car light.
Further, in one embodiment, can be to utilize OBD system cycle ground to come the step S1-S6 shown in the execution graph 1.This be because, the current geographic position of vehicle and current time all are constantly to change, correspondingly the appropriate state of headlight also changes along with the variation of the two, therefore, in order to guarantee that headlight is under the suitable state all the time, be necessary to utilize OBD system cycle ground to come the operation of execution in step S1-S6.Then can carry out according to actual needs automatic setting or manually set by chaufeur as for the length in cycle, thereby satisfy different user demands and vehicle environmental.
Continue, in another embodiment, above-mentioned vehicle light control method also comprised the steps before step S1, that is: utilize the OBD system to determine whether the chaufeur of vehicle has carried out the operation that opens or closes of headlight, if it is execution in step S1-S5(or S1-S6).This be because, purpose of the present invention namely is to provide the accuracy of headlight control, and all there is the risk of error in the control operation (namely opening or closing) that each chaufeur carries out headlight, therefore, in order to eliminate the human error that may exist, present embodiment can utilize the operation input state of OBD system monitoring headlight, in case when determining that chaufeur has carried out the control operation of headlight, the OBD system just carries out the operation of a step S1-S6, suitable with the operation of guaranteeing chaufeur, thus the accuracy that headlight operates also guaranteed.
Corresponding to above-mentioned vehicle light control method, embodiments of the invention also propose a kind of OBD system that implements vehicle light control method, as shown in Figure 2, this OBD system comprises GPS device 21, clock apparatus 22, analytical equipment 23, state reading device 24 and behavior control device 25.Wherein, GPS device 21 is used for obtaining the current geographical location information of vehicle; Clock apparatus 22 is used for obtaining the current time; Analytical equipment 23 is used for judging according to geographical location information and current time that vehicle is current and is in daytime or night; State reading device 24 is used for reading the current headlight state of vehicle; Behavior control device 25 is used for the state according to the reading result control headlight of the judged result of analytical equipment and state reading device.
Wherein, judge and to draw that vehicle is current to be in daytime if install by analysis 23, and to read front car light through state reading device 24 be open mode that then behavior control device 25 is closed front car light; Judge and to draw that vehicle is current to be in night if install by analysis 23, and to read front car light through state reading device 24 be closed condition that then behavior control device 25 is opened front car light.Otherwise, judge and to draw that vehicle is current to be in daytime if install by analysis 23, and state reading device 24 to read front car light be closed condition; Perhaps, judge and to draw that vehicle is current to be in night if install by analysis 23, and state reading device 24 to read front car light be open mode; Then behavior control device 25 keeps the state of headlight.
In one embodiment, the geographical location information that GPS device 21 obtains specifically comprises longitude and latitude information, and correspondingly, then analytical equipment 23 specifically comprises acquiring unit 231, comparing unit 232 and judging unit 233.Wherein, acquiring unit 231 be used for according to longitude and latitude information obtain corresponding at sunrise between and sunset time; Comparing unit 232 compares with sunset time for the current time that clock apparatus 22 is obtained and at sunrise; 233 of judging units are used for judging according to the comparative result of comparing unit that vehicle is current and are in daytime or evening.Wherein, if the current time the same day at sunrise between and between the sunset time, then judging unit 233 judges that drawing vehicle is in daytime; If the current time the sunset time on the same day and second day at sunrise between between, then judging unit 233 judges that drawing vehicle is in night.
