A method for increasing the power during an acceleration process of an electrically operated motor vehicle with at least one electrical machine includes detecting a storage request by at least one control unit and initiating an increase in the rotation speed of a rotor of the electrical machine of the motor by the control unit before an acceleration request, so that kinetic energy is stored in the rotor of the electrical machine. The acceleration request is detected by the control unit and the energy stored in the rotor of the electrical machine is released during the acceleration process.

Method for increasing the power during an acceleration process of an electrically operated motor vehicle

Methods are provided for checking the actuating accuracy of a clutch arranged in a force flow between a fixable shaft and an electric machine of an electric or hybrid motor vehicle when at a standstill. One method includes: fixing the shaft, setting a defined setpoint torque on the clutch to be checked, continuously ramping up the electric machine up until the first slipping of the clutch, comparing the achieved torque of the electric machine with the setpoint torque preset on the clutch. Another method includes: fixing the shaft, ramping up the electric machine to a defined rotational speed, setting a defined setpoint torque on the clutch to be checked, comparing the torque of the electric machine needed to maintain a constant rotational speed with the setpoint torque set on the clutch.
