APPARATUS, BRAKE SYSTEM AND METHOD FOR CONTROLLING PASSIVE BRAKE DEVICE

The present invention relates to a device (V) for controlling a passive braking device (2), in particular a passive electromechanical braking device, wherein the device (V) comprises: an electric motor (M) for releasing the passive braking device (2) against a spring force; a motor control unit (4) for controlling the electric motor (M) for service braking and/or emergency braking, wherein the motor control unit (4) is detachably electrically connected to the electric motor (M), a first brake control unit (6) for safety braking, wherein the first brake control unit (6) is detachably electrically connected to the electric motor (M), and a second brake control unit (8) for parking braking, wherein the second brake control unit (8) is detachably electrically connected to the electric motor (M), wherein the service braking and/or emergency braking by means of the motor control unit (4), the safety braking by means of the first brake control unit (6) and the parking braking by means of the second brake control unit (8) are functionally independently activatable relative to one another. Furthermore, the present invention relates to a braking system (BS) with said device (V) and a method for controlling a passive braking device (2), in particular a passive electromechanical braking device.
