The invention provides a motor controller with an automatic parking control function for an electric vehicle, a power assembly and an automatic parking control method for the electric vehicle. The power assembly comprises a motor controller and a motor, and the motor controller is used for controlling the output torque of the motor. In the driving process of the electric vehicle, the motor controller responds to the torque signal and is used for controlling the motor to output a torque value indicated by the torque signal. In the parking process of the electric vehicle, the motor controller is used for controlling the motor to drive the electric vehicle to run for a preset distance, and in the process that the motor controller controls the motor to drive the electric vehicle to run for the preset distance, the motor controller controls the torque output by the motor to change along with the change of the running distance of the electric vehicle. According to the power assembly, the motor controller and the control method, the signal transmission time delay in the automatic parking process of the electric vehicle can be reduced, and the control speed and accuracy of the automatic parking process are improved.
