摘要:
A method for hydraulically boosting a vehicle electric parking brake having a hydraulic service brake and an electric parking brake. Application forces electically generated by the parking brake function is superimposed on the boosting brake force generated by a hydraulic boosting brake pressure provided by the service brake to the brake actuator. When the parking brake is actuated to generate a predetermined application force, the force generated by the brake actuator is detected as the actual value, if an actual value of the measured value is smaller than a first target value a boosting brake pressure value is applied to the brake actuator, and by means of the parking brake function an adjustment function for the tension of the brake actuator to which the hydraulic boosting brake pressure is applied is carried out to achieve the predetermined application force.

摘要:
Disclosed is a method for the prevention of erroneous actuator access in a multifunctional general electronic control system wherein the actuator access requirements emanate from different system services (1), a rights management (2), which determines the authorization of actuator access requirements, a mode of operation control unit (4), and an access management (6) are integrated into the general control system. The rights management (2), in the event of an access requirement by a system service (1), brings about an adjustment or a change of the mode of operation according to predefined rules in consideration of the instantaneous mode of operation of the general system and reports the current mode of operation to the access management (6). Depending on the reported general mode of operation, the access management (6) allows actuation of the actuator by means of the ‘authorized’ system service (1) and processes the actuator access requirements of the system services (1) according to predefined arbitration rules.
