The invention provides a motor controller for vehicle pivot steering, a power assembly and a vehicle. The motor controller is used for controlling a motor to drive a wheel of the vehicle. The vehicle further comprises the other three motors, and the other three motors are used for driving the other three wheels respectively. One motor and the other three motors are used for driving the vehicle to steer in situ, and in the vehicle in-situ steering process, the motor controller is used for receiving a torque indication signal and controlling the output torque of one motor, and responding to the situation that the rotating speed change value of one motor within a preset duration is smaller than a first threshold value; and the motor controller controls a motor to output torque according to the torque indicated by the torque indication signal. And in response to the condition that the rotating speed change value of one motor within the preset duration is greater than or equal to the first threshold value, the motor controller controls the torque output by one motor to be less than or greater than the torque indicated by the torque indication signal. The motor controller actively adjusts the torque output of the motor, so that the steering center of the vehicle is prevented from deviating.
本申请提供一种用于车辆原地转向的电机控制器、动力总成和车辆,电机控制器用于控制一个电机驱动车辆的一个车轮。车辆还包括其他三个电机,其他三个电机分别用于驱动其它三个车轮。一个电机和其他三个电机用于驱动车辆原地转向,车辆原地转向的过程中电机控制器用于接收扭矩指示信号并控制一个电机的输出扭矩,响应于一个电机在预设时长内的转速变化值小于第一阀值,电机控制器根据扭矩指示信号指示的扭矩控制一个电机输出扭矩。响应于一个电机在预设时长内的转速变化值大于或者等于第一阀值,电机控制器控制一个电机输出的扭矩小于或大于扭矩指示信号指示的扭矩。电机控制器通过主动调整电机的扭矩输出,避免车辆的转向中心发生偏移。
