VEHICLE

A vehicle, in particular to a rail vehicle, has at least one drive motor and a brake control device. A monitoring device measures, in the braking mode of the vehicle, at least one drive current which flows through the drive motor, and at least one drive voltage which is applied to the drive motor, to form measured values, and to generate operational information which specifies the mode of operation of the drive motor, in particular braking information which specifies a braking effect of the drive motor, on the basis of the measured values.
