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.

A method for damping juddering in a drive train of a vehicle having an electric motor as a drive motor, the method comprising:
- 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.
A vehicle, comprising:
- a drive train having an electric motor as the drive motor;
- and
- a closed-loop control system including at least partially comprising hardware configured to, configured to:
- calculate 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
- calculate 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.
