Claim 13:
14. A braking device for a vehicle, comprising:
a first obtaining module, configured to obtain a first state information of the vehicle, wherein the first state information comprises a vehicle mass and a deceleration required by braking;
a calculation module, configured to calculate a braking torque required by the vehicle according to the first state information;
a control module, configured to control an output of an electric braking torque according to the braking torque required by the vehicle; and
a second obtaining module, configured to obtain a current vehicle speed of the vehicle and a maximum electric braking exit speed, wherein
if the deceleration required by braking of the vehicle changes to zero, the control module is further configured to control the vehicle to unload the electric braking torque when the current vehicle speed is less than the maximum electric braking exit speed.
