Abstract: An actuator for an electric parking brake, EPB, is described. The actuator comprises a motor configured to actuate an actuating member of the EPB, as well as a reception interface configured to receive an enablement code. An enablement code is assigned to the EPB actuator which individualizes the EPB actuator against other EPB actuators. The actuator further comprises an evaluation unit configured to verify the received enablement code on the basis of the enablement code allocated to the EPB actuator and to enable a control of the motor in case of a positively verified enablement code. There is further provided a control device for the EPB actuator, an electric parking brake and a vehicle having the EPB actuator and corresponding operating methods.

Abstract: A measuring system for linear and angular movements with a first length or angle sensor (3) which operates in accordance with a first measuring method and which converts an input value (s, alpha) in the form of a linear or angular movement into an electrically processible first output value (UPOT) is further developed to increase the functional reliability and to avoid "coomon model" errors in such a manner that a second length or angle sensor (1) which is mechanically coupled with the first length or angle sensor (3) is provided which operates to a measuring method that is different from the first measuring method, and which converts the linear and angular movement (s, alpha) into an electrically processible second output value (UPULS), with the first and second output value (UPOT, UPULS) being available for subsequent processing and evaluation.

Abstract: An apparatus for controlling the brake pressure in a vehicle brake system equipped with an electronically adjustable brake booster (10), comprising an actuator (22) which transmits the actuating movement of the brake pedal to a master brake cylinder and has assigned a path limiting element (80) which limits the axial actuating movement of the actuator (22) in that it is received between abutments (90, 92), the apparatus being characterized in that a switch is actuated by the path limiting element (80) together with one of the abutments (90), said switch supplying a signal to the brake booster when the path limiting element (80) abuts the one abutment (90).

Abstract: The vehicle brake system including an electronically controlled brake booster (10), comprising a first actuator (350) which is connected to a second actuator (360) for transmitting to the same an actuating movement (P) of a brake pedal, wherein the second actuator (360) transmits the movement to a master brake cylinder, a signal generator (365) disposed between first and second actuators (350, 360) for generating a signal to be supplied to the controller of the brake booster (10), wherein the signal generator (365) is triggered by a relative movement between the first actuator and the housing of the brake booster.
