Rail vehicle having power limiter

1. A rail vehicle, comprising:

a drive controller for providing drive power required for movement of the rail vehicle;

a man-machine interface connected to said drive controller and configured to demand a drive power from said drive controller; and

a limiter module connected to said drive controller for limiting said drive power able to be demanded by said man-machine interface, said limiter module defining a maximum value for said drive power, depending on running data of the rail vehicle, and said running data including data reflecting compliance with a timetable of the rail vehicle.

2. The rail vehicle according to claim 1 , wherein said limiter module adapts the maximum value for the drive power able to be demanded, if said running data reflects non-compliance with the timetable of the rail vehicle.

3. The rail vehicle according to claim 1 , wherein said limiter module is part of said drive controller.

4. The rail vehicle according to claim 1 , wherein said limiter module is an external appliance acting through a vehicle bus on said drive controller or said man-machine interface.

5. A method for driving a rail vehicle, the method comprising the following steps:

providing a drive controller for providing drive power required for movement of the rail vehicle;

providing a man-machine interface connected to the drive controller for demanding the drive power from the drive controller;

providing running data of the rail vehicle;

computing a maximum value for the drive power depending on the running data;

limiting the drive power able to be demanded via the man-machine interface to the maximum value; and

demanding the drive power via the man-machine interface.
