Motor controller for vehicle pivot steering, power assembly and vehicle

Abstract

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.
