Vehicle fault remote diagnosis system and method

The invention provides a vehicle fault remote diagnosis system, which includes a remote diagnosis ECU and a remote diagnosis server. The remote diagnosis ECU is connected with a CAN bus of a vehicle. The remote ECU collects fault information stored in ECUs on the vehicle and collects real-time dynamic information of the vehicle according to the needs of a user. Meanwhile, the remote diagnosis ECU executes the real-time information interaction between the vehicle and the remote diagnosis server. The ECUs on the vehicle refer to all the other ECUs on the vehicle except the remote diagnosis ECU. The remote diagnosis server stores an ECU diagnosis database, the vehicle model and the vehicle VIN code information, sends the collected diagnosis request of the user to the remote diagnosis ECU, and converts fault data returned by the remote diagnosis ECU into a diagnosis result which is sent to the user. According to the invention, a faulty vehicle can be remotely diagnosed in real time, the influence of the remote diagnosis on the normal running of the vehicle is eliminated, and the vehicle driving safety is ensured.
