Abstract
A vehicle and a braking method and a device therefor are 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 the vehicle to output an electric braking torque according to the braking torque required by the vehicle; obtaining a current vehicle speed of the vehicle and an electric braking exit protection speed; and calculating an electric braking exit speed according to the braking torque required by the vehicle and the deceleration required by braking, and controlling the vehicle to unload the electric braking torque when the current vehicle speed is less than a larger one of the electric braking exit speed and the electric braking exit protection speed.
