Abstract
A torque compensation method of a vehicle, a torque compensation device of the vehicle, and an associated computer readable storage medium. The method comprises: when a vehicle control module of the vehicle determines that the vehicle is in a brake free play coasting state, the vehicle control module acquires a pressure of a brake master cylinder of the vehicle, and controls a motor of the vehicle to output a compensation torque according to the pressure of the brake master cylinder. The application can accurately determine the brake free play range of the vehicle, control the motor of the vehicle to timely output the compensation torque, thereby effectively inhibiting the brake free play coasting of the vehicle and ensuring driving safety.
