Preferably, the described remote monitoring center fault diagnosis result that also is used for generating passes through vehicle user.
Preferably, described remote monitoring center also is used for the diagnostic trouble code of long-range removing vehicle electrically controlling system, and closes the alarm indicator on the panel board.
The vehicle fault remote that the present invention proposes detects diagnostic method, comprises following treatment step:
1) remote control center issues remote failure by cordless communication network and detects and to instruct vehicle communication terminal;
2) vehicle communication terminal will detect instruction and be forwarded to fault detector, and fault detector carries out fault detect by vehicle self diagnosis interface;
3) fault detector sends to remote control center with testing result by vehicle communication terminal;
4) remote control center generates fault diagnosis result according to testing result.
Preferably, also comprise following treatment step before the described step 1): vehicle user is initiated the request of vehicle remote fault diagnosis to remote control center.
Preferably, also comprise following treatment step after the described step 4): remote monitoring center passes through vehicle user with the fault diagnosis result that generates.
Preferably, also comprise following treatment step after the described step 4): the diagnostic trouble code of the long-range removing vehicle electrically controlling system of remote monitoring center, and close alarm indicator on the panel board.
Adopt vehicle fault remote detecting diagnosis system of the present invention and diagnostic method thereof, remote control center can regularly carry out remote failure to vehicle and detect diagnosis, and vehicle user also can initiatively be initiated remote failure to remote control center and detect diagnosis request.The mode of the present invention by fault detect is separated with fault diagnosis improved the versatility of equipment, can support most of medium-to-high grade automobile.The present invention can detect a plurality of systems of vehicle and diagnose, and in time notifies vehicle user with diagnostic result, and can and close alarm indicator according to the long-range removing diagnostic trouble code of diagnostic result.
Description of drawings
Fig. 1 is the vehicle fault remote detecting diagnosis system schematic diagram that the present invention proposes;
Fig. 2 is that the vehicle fault remote that the present invention proposes detects the diagnostic method process flow diagram.
Embodiment
Below in conjunction with accompanying drawing vehicle fault remote detecting diagnosis system of the present invention and method are elaborated.
Vehicle fault remote detecting diagnosis system schematic diagram as shown in Figure 1, fault detector is installed in the vehicle, by vehicle self diagnosis interface vehicle is carried out fault detect.For versatility that fault detector is provided and reduce cost, fault detector can be designed to only possess fault detection capability, promptly only extracts vehicle trouble information, does not carry out fault analysis.Fault detector can detect one or more in the following parts of vehicle: engine, ripple case, air bag, ABS, panel board, burglary-resisting system, sound system, air-conditioning system etc.Vehicle communication terminal links to each other with fault detector, be responsible for the fault detector testing result that receives is forwarded to remote control center by cordless communication network, and the remote failure of remote control center is detected instruction be issued in the described fault detector and carry out.Vehicle communication terminal can be the GPRS data communication units, also can adopt existing vehicle GPS monitor terminal, and it carries out data interaction by cordless communication networks such as GPRS and remote control center.Remote control center is used for generating fault diagnosis result according to testing result.Remote monitoring center can also be with the fault diagnosis result that generates by vehicle user, diagnostic trouble code that can also long-range removing vehicle electrically controlling system, and close alarm indicator on the panel board.
Vehicle fault remote as shown in Figure 2 detects the diagnostic method flow process, and treatment scheme is as follows:
1) remote control center is initiated remote failure by the GPRS communication network and is detected, and promptly issues remote failure and detects and instruct vehicle communication terminal;
