The invention discloses an electric vehicle fault processing system and method, the system comprises a vehicle control unit and vehicle-mounted controllers connected with the vehicle control unit through a CAN network, each vehicle-mounted controller sends a fault flag bit and a fault level to the vehicle control unit through the CAN network after a fault occurs, and the vehicle-mounted controllers are connected with the vehicle control unit through the CAN network. And the vehicle control unit carries out integration processing according to the fault flag bit and the fault level sent by each vehicle-mounted controller and outputs a corresponding control strategy. The method has the advantages that the method is suitable for fault processing of the electric automobile, faults reported by all the controllers of the whole automobile are processed and arbitrated, the safety of the whole automobile is comprehensively considered, and corresponding control strategies are executed, so that the safety of the electric automobile is improved.

    本发明公开了一种电动汽车故障处理系统及方法,包括整车控制器及通过CAN网络与整车控制器连接的各车辆车载控制器,所述各车载控制器在发生故障后通过CAN网络将故障标志位和故障等级发送至整车控制器,所述整车控制器根据各个车载控制器发来的故障标志位及故障等级进行整合处理并输出对应的控制策略。本发明的优点在于:适用于电动汽车的故障处理,对整车的所有控制器报出的故障进行处理与仲裁,综合考虑整车的安全性执行对应的控制策略,从而提高了电动汽车的安全性。
