Device and method for saving traction energy in rail vehicles
The invention relate to, among other things, a device (5) for a rail vehicle that comprises a control unit (10), which calculates a switch off time using given data and measured values after which the coasting rail vehicle arrives on time at the next stop stipulated by the time-table while adhering to the same. The aim of the invention is to make it possible to reliably detect deviations of the actual travelling characteristics from travelling characteristics recommended by the device. To this end, the invention provides that the device (5) comprises a data input (E5) at which an actual value signal (Si) stating the actual drive switch off time can be input into the device (5), whereby the actual drive switch off time indicates the time at which the drive was actually switched off after the generation of the switch off signal. In addition, the invention provides that the control unit (10) has a memory in which it stores the actual and the respectively assigned recommended drive switch off time (tab, ist; tab, soll) for evaluation.
