Abstract

In a method for braking a vehicle with the aid of at least one electric machine, operated as a generator, of the vehicle, a torque generated by the electric machine is controlled by a damping control function in order to reduce a periodic deflection of a drive train, coupled to a rotor shaft of the electric machine, relative to the rotor shaft. Furthermore, a braking request signal representing a target braking torque is detected, a deactivation condition for deactivating the damping control function is identified on the basis of the braking request signal, the damping control function is deactivated when a deactivation condition is identified, a braking torque is generated based on the braking request signal by operating the electric machine as a generator, a reactivation condition for reactivating the damping control function is identified during the process of generating the braking torque, and the damping control function is reactivated when the reactivation condition is identified.
