The invention discloses a fault processing method of a central distributed electric drive system and a vehicle, and belongs to the technical field of vehicle control. The central distributed electric drive system comprises a motor controller, a first motor and a second motor, the first motor and the second motor are coaxial, and the method comprises the steps that the motor controller controls the first motor and the second motor to enter a safety mode under the condition that the first motor or the second motor has a preset fault, and the preset fault is the fault with the highest severity level; the safety mode comprises a free-wheel FW mode; taking the motor entering the FW mode as a current motor, and controlling the current motor to maintain the FW mode under the condition that the current motor has a preset fault; and under the condition that the current motor does not have the preset fault, controlling the current motor to exit the FW mode. According to the technical scheme provided by the invention, when any motor has the fault with the highest severity level, the two coaxial motors enter the safety mode, so that instantaneous response synchronization of the left wheel and the right wheel is guaranteed, and the safety of the vehicle is improved.
本申请公开了一种中央分布式电驱系统的故障处理方法及车辆,属于车辆控制技术领域。其中,中央分布式电驱系统包括电机控制器、同轴的第一电机和第二电机,所述方法包括:电机控制器在第一电机或第二电机出现预设故障的情况下,控制第一电机和第二电机进入安全模式,其中,预设故障为严重等级最高的故障,安全模式包括自由轮转FW模式;将进入FW模式的电机作为当前电机,在当前电机出现预设故障的情况下,控制当前电机保持FW模式;在当前电机未出现预设故障的情况下,控制当前电机退出FW模式。本申请提供的技术方案在任意电机发生严重等级最高的故障时,使同轴的两个电机均进入安全模式,以保障左右轮的瞬时响应同步,提高了车辆的安全性。
