METHOD FOR CONTROLLING A DRIVE-OFF PROCESS OF A RAILWAY VEHICLE

摘要

A method controls a drive-off process of an electrically driven vehicle, the electric motor of which is fed via a converter. A holding torque necessary to prevent the vehicle from rolling back is determined. By using sensors for determining carriage masses and sensors for determining route inclinations, the holding torque can be precisely determined. In order to achieve a drive-off process of the electrically driven vehicle that is gentle on the electric motor and as long as a determined rotational motor speed is less than a specified limit rotational speed, a traction torque is limited by a control unit of the vehicle to a limit torque dependent on the holding torque, and the traction torque is increased beyond the limit torque by the control unit only once the rotational motor speed is greater than the limit rotational speed.
