The invention provides a vehicle control unit abnormity detection method of an electric vehicle and the electric vehicle, the electric vehicle comprises a vehicle control unit, a motor controller and a battery management system, and the motor controller and the battery management system are respectively provided with an output control interface for controlling the vehicle control unit to close a CAN output signal. The method comprises the steps that a motor controller and/or a battery management system judges whether a vehicle control unit is abnormal or not according to a CAN output signal of the vehicle control unit; and if yes, the motor controller and/or the battery management system controls the vehicle control unit to close output through the corresponding output control interface. According to the abnormity detection method for the vehicle control unit of the electric vehicle, the motor controller and the battery management system can detect whether the vehicle control unit is abnormal or not through the signal output by the vehicle control unit, and when it is detected that the vehicle control unit is abnormal, the output of the vehicle control unit is controlled, so that the reliability of the vehicle is improved.
本申请提出一种电动汽车的整车控制器异常检测方法及电动汽车,其中,电动汽车包括整车控制器、电机控制器与电池管理系统,电机控制器与电池管理系统均具有控制整车控制器的关闭CAN输出信号的输出控制接口,方法包括:电机控制器和/或电池管理系统根据整车控制器的CAN输出信号判断整车控制器是否异常;如果是,则电机控制器和/或电池管理系统通过对应的输出控制接口控制整车控制器关闭输出。本申请的电动汽车的整车控制器异常检测方法,可以由电机控制器、电池管理系统通过整车控制器输出的信号检测整车控制器是否存在异常,并在检测出整车控制器发生异常时,对整车控制器的输出进行控制,从而提升车辆的可靠性。
