1. A method for braking a vehicle with at least one electric machine, operated as a generator, of the vehicle, wherein a torque generated by the electric machine is controlled by a processor implementing 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, wherein the method comprises the following steps:
detecting, by the processor, a braking request signal representing a target braking torque;
identifying, by the processor, a deactivation condition to deactivate the damping control function on the basis of the braking request signal;
deactivating, by the processor, the damping control function when a deactivation condition is identified;
generating, by the processor, a braking torque based on the braking request signal by operating the electric machine as a generator;
identifying, by the processor, a reactivation condition for reactivating the damping control function during the process of generating the braking torque; and
reactivating, by the processor, the damping control function when the reactivation condition is identified.
