A control device for the parking brake of a motor vehicle has a hydraulic cylinder with a piston chamber that can be pressurized by means of a valve arrangement, and has a hydraulic piston connected mechanically to engagement elements of the parking brake. The parking brake is forced into an engaged or disengaged position depending on the hydraulic pressure in the piston chamber. The piston chamber connects to a pressure sensor providing pressure signals that represent the state of the parking brake and that are evaluated by an electrical control unit. The control unit defines a first predetermined pressure threshold corresponding to the engaged state of the parking brake, and a second predetermined pressure threshold corresponding to the disengaged state of the parking brake.

An emergency release device for the parking lock of a motor vehicle is described which contains an locking device ( ) that is pressed into its engaged position by a spring element ( ) and which can move into its disengaged position by at least one actuator ( ) that is actuated by a control element ( ) against the spring force. The locking device ( ) can be linked with a clutch pedal located on the operator's station by releasable mechanical connecting elements ( ), in such a way that it is possible to emergency-release the parking lock in case of vehicle malfunction.

A control device for the parking lock of a motor vehicle has at least one actuating drive ( ) that can be operated by triggering devices and with which a locking device ( ) can be moved between engaged and disengaged positions. For reliable operation, at least two independent triggering devices are provided and a change in position takes place only if both triggering devices ( ) are actuated. Preferably a hydraulic piston ( ) brings the parking lock into its disengaged position when subjected to pressure. The triggering devices are constructed as solenoids ( ) under the control of two electrical controllers ( ) that undertake an evaluation of relevant control and measurement parameters.

An electric drive motor with a rotor in the form of an external rotor and with a stator, which has a base body comprised of heat conductive material. A bearing hub for the rotor and a support that extends radially away from the hub and is for containing a printed circuit board. The printed circuit board is equipped with electronics and is disposed on a side of the support oriented away from the rotor for the sake of an improved removal of the dissipated heat that is produced in the electronics, a multitude of concentric cooling ribs are embodied on the radial surface of the support oriented toward the rotor.
