Abstract
A braking method includes: obtaining a first state information of the vehicle, which includes a vehicle mass and a deceleration required by braking; calculating a braking torque according to the first state information, and controlling the vehicle to output an electric braking torque according to the braking torque; obtaining a current vehicle speed and a mechanical braking application delay time; calculating an electric braking exit speed according to the braking torque required by the vehicle and the deceleration required by braking; calculating a mechanical braking application speed according to the mechanical braking application delay time, the deceleration required by braking, and the electric braking exit speed; and determining whether to control the vehicle to unload the electric braking torque, and whether to control the vehicle to apply a mechanical braking torque according to the current vehicle speed, the electric braking exit speed, and the mechanical braking application speed.
