Description

Vehicle remote control system based on the CAN bus

[technical field]

The utility model relates to vehicle control technology field, particularly based on the vehicle remote control system of CAN bus.

[background technology]

Vehicle is more and more important in our daily life.Along with scientific technological advance vehicle degree of automation is more and more higher, the wireless network protection face is increasing simultaneously, and the CAN bus is more and more universal in vehicle, some vitals of vehicle now substantially all join in the vehicle CAN bus network, as Engine ECU (electronic control unit), ABS(anti-lock brake system), Automatic Transmission, car light, air-conditioning, Door Lock and the control of vehicle motor special etc.But vehicle monitoring now and diagnosis can only can only be controlled simple door contact interrupter lock, air conditioning switch, vehicle window etc. with special tool monitoring, Long-distance Control substantially at the vehicle scene; Uncontrollable vehicle rotating speed etc.; Can't satisfy vehicle automation and intelligentification development need.

A kind of " Vehicular intelligent safety control system and method for supervising " disclosed in prior art, see that publication number is: CN102323816A, open day be: the Chinese patent of 2012.01.18, this Vehicular intelligent safety control system, comprise: the bus analysis module, be connected with the CAN bus, be used for directly obtaining the current various running datas of automobile; One key starts module, is connected with the CAN bus, starts corresponding executive command by the information on the CAN bus; Position module is connected with the CAN bus, is used for obtaining the current location information of automobile; Communication module is connected with the CAN bus, is used for uploading the data to long-range background server; The server calling module is used for and described communication module swap data; And background processing module, be connected with described server calling module, the data that receive for the treatment of described server calling module, and command information is delivered to described server calling module.This beneficial effect of the invention is: this system has realized the bidirectional data transfers of vehicle-network-background server, monitoring function.But this system can not be to Engine ECU, and ABS, Automatic Transmission, car light, air-conditioning, Door Lock and vehicle motor special are controlled.

[summary of the invention]

The technical problems to be solved in the utility model is to provide a kind of vehicle remote control system based on the CAN bus, has improved the controlled of vehicle and vehicle driving safety.

The utility model is achieved in that a kind of vehicle remote control system based on the CAN bus, comprising: the controller, CAN bus module and the remote control center that are installed on the car-mounted terminal on vehicle; The controller of described car-mounted terminal comprises wireless module, terminal controller and the CAN communication module that connects successively, and described CAN communication module is connected with described CAN bus module; Described wireless module is connected with described remote control center through wireless network.

Further, described vehicle set has: electric machine controller, variable-speed controller, anti-lock brake system ABS, Engine ECU, instrument carrier panel, light equipment, automatic seat, interior environment system, electric window, electric door lock and safety air bag; Described instrument carrier panel is connected with described CAN bus module; Described electric machine controller, variable-speed controller, anti-lock brake system ABS, Engine ECU all are connected with the high speed network segment of the CAN bus network of described CAN bus module; Described light equipment, automatic seat, interior environment system, electric window, electric door lock, safety air bag all are connected with the low speed network segment of the CAN bus network of CAN bus module.

The utility model has the advantage of: remote control center of the present utility model can be long-range reads significant data message on the vehicle CAN bus module by the controller that is installed on the car-mounted terminal on vehicle, simultaneously data message is reset and sends the relevant control order, come remote monitor and control, diagnosis and control vehicle, it has improved the operational vehicle level of management, can realize vehicle anti-theft, vehicle is anti-snatch and lack of standardization with safety controls such as car remote tracing speed limits, has improved the controlled of vehicle and vehicle driving safety.
