VEHICLE AND SLIDING FEEDBACK CONTROL SYSTEM OF VEHICLE AND METHOD FOR THE SAME

摘要

A sliding feedback control system of a vehicle is provided. The system includes: an electric motor; a power battery; a battery manager connected with the power battery, and configured to obtain a maximum charging power of the power battery; and a motor controller connected with the electric motor, and configured to obtain maximum feedback torque values of the motor controller and the electric motor, to convert the maximum charging power of the power battery into a maximum feedback torque value of the power battery, to determine a minimum of the maximum feedback torque values as a first feedback torque value, to obtain a second feedback torque value, and to determine a final feedback torque value of the electric motor as a minimum of the first and second feedback torque values, such that the electric motor controls the vehicle to perform the sliding feedback operation according to the final feedback torque value.
