Abstract
A rail vehicle braking device has at least one electrodynamic brake, which comprises a drive unit, which has at least one drive motor and a power supply unit for supplying the drive motor when the drive unit is in a traction mode. The rail vehicle braking device has at least two brake control units in order to increase the safety of the electrodynamic brake. In a first braking mode, a first brake control unit in an active state controls the power supply unit for providing a braking effect, a first brake effect monitoring unit and a switching unit, which serves to switch, depending on a brake effect parameter in the first braking mode, into a second braking mode, in which the second brake control unit in an active state controls the power supply unit for providing a brake effect.
