Abstract

A braking method for a vehicle is provided. The method includes the following steps: obtaining a first state information of the vehicle, where the first state information includes a vehicle mass and a deceleration required by braking; calculating a braking torque required by the vehicle according to the first state information, and controlling an output of an electric braking torque according to the braking torque required by the vehicle; obtaining a current vehicle speed of the vehicle and a maximum electric braking exit speed; and; controlling, if the deceleration required by braking of the vehicle changes to zero, the vehicle to unload the electric braking torque when the current vehicle speed is less than the maximum electric braking exit speed. A braking device for a vehicle and a vehicle are further provided.
