The invention provides a motor controller for redundant parking, a redundant parking method and a power assembly, if any one of the following preset conditions is met in the process of receiving a parking signal by the motor controller, parking current is output to a driving motor, the parking current is used for controlling the rotating speed of the driving motor to be reduced, and the parking current is used for controlling the rotating speed of the driving motor to be reduced. The parking signal is used for indicating the electric vehicle to execute a parking action, and the preset condition comprises that the rotating speed of the driving motor is greater than zero or the rotating speed of the driving motor is increased after the parking signal lasts for a first preset duration. Under the condition that parking of an original electronic parking brake system fails, the parking current is output to the driving motor, so that the rotating speed of the driving motor is reduced, redundant parking of the electric vehicle is completed, and the parking safety of the electric vehicle is improved under the condition that hardware cost is not increased.

    本申请提供一种用于冗余驻车的电机控制器、冗余驻车的方法及动力总成,电机控制器在接收驻车信号的过程中若满足以下任一预设条件,则向驱动电机输出驻车电流,其中,驻车电流用于控制驱动电机的转速降低,驻车信号用于指示电动汽车执行驻车动作,其中,预设条件包括:在驻车信号持续第一预设时长后驱动电机的转速大于零,或者,驱动电机的转速增加。在原有电子驻车制动系统驻车失败的情况下,本申请通过向驱动电机输出驻车电流,使驱动电机降低转速,从而完成电动汽车的冗余驻车,在不增加硬件成本的情况下,提升电动汽车的驻车安全性。
