The invention discloses a fault processing method and device for a vehicle electric drive system and a vehicle, and the method comprises the steps: responding to a preset fault signal of the vehicle electric drive system, and controlling a motor controller of the vehicle electric drive system to be switched from a normal mode to a safe mode, the safety mode is a mode in which the vehicle control unit is prohibited from issuing a control instruction to the motor controller; after the motor controller enters the safety mode, if a preset condition is met, a software control program used for controlling the motor controller is adjusted so as to allow the whole vehicle controller to issue a control instruction to the motor controller; if the target control instruction is issued to the motor controller after the software control program is adjusted, the motor controller is controlled to execute the target control instruction according to the safety response strategy. According to the invention, the technical problem of low driving safety of the vehicle is solved.
本发明公开了一种车辆电驱系统的故障处理方法、装置及车辆,该方法包括:响应于车辆电驱系统的预设故障信号,控制车辆电驱系统的电机控制器由正常模式切换至安全模式,安全模式为禁止整车控制器向电机控制器下发控制指令的模式;在电机控制器进入安全模式之后,若满足预设条件,调整用于控制电机控制器的软件控制程序,以允许整车控制器向电机控制器下发控制指令;若在调整软件控制程序之后向电机控制器下发目标控制指令,控制电机控制器按照安全响应策略执行目标控制指令。通过本发明解决了车辆的驾驶安全性低的技术问题。
