Abstract
A method for damping juddering in the drive train of a vehicle having an electric motor as the drive motor, and a vehicle having a closed-loop control system to carry out the method. The method includes calculating an electric motor setpoint torque for actuating the electric motor from an electric motor request torque which corresponds to a current request for a torque, and calculating a correction torque as a function of the electric motor request torque and a correction factor which is determined from a rotational speed of the electric motor.
