Method for controlling a drive-off process of a railway vehicle

A method for controlling a drive-off process of an electrically driven vehicle, with which a holding torque necessary for preventing the electrically driven vehicle from rolling back is determined, which comprises the steps of:

• limiting a traction torque via a control unit of the electrically driven vehicle to a torque limit dependent on the holding torque if a determined motor revolution rate is less than a predetermined first revolution rate limit;
• and
• raising the traction torque above the torque limit by the control unit if the determined motor revolution rate exceeds the predetermined first revolution rate limit.

A control system for an electrically driven vehicle having at least one electric motor and a converter for supplying the electric motor, the control system comprising:

• a control unit for controlling the converter, said control unit configured to determine a holding torque that is necessary to prevent rolling back of the electrically driven vehicle, said control unit further configured to control the converter so that a determined motor revolution rate is less than a predetermined first revolution rate limit, and a traction torque of the vehicle is limited to a torque limit that is dependent on the holding torque and the traction torque is only then raised above the torque limit if the determined motor revolution rate is greater than the predetermined first revolution rate limit.
