Abstract: A method for controlling an electric parking brake for a motor vehicle including a brake actuator having an electric motor disposed directly on the brake caliper. When the parking brake is utilized as an additional service brake, depending on a brake pedal brake command, the electric motor is initially energized on detection of an imminent or commencing brake-pedal actuation however the electric motor generates no braking force until a predetermined or specific brake command is received. As a result, an overload of the vehicle voltage source is avoided if simultaneous utilization of multiple parking-brake actuators occurs.

Abstract: A method of controlling a brake system of a motor vehicle having a braking assistance function. The brake system including a master brake cylinder, activated with a brake pedal. A distance s between a valve piston connected to the brake pedal, and a transmission element, connected to a pressure piston of the master brake cylinder is sensed and the brake system is controlled as a function of the sensed distance s. Within the scope of this monitoring process, brake pedal release is detected even when the pressure-generating unit is activated. In addition, despite an active braking assistance function, consistent interplay occurs between activation by the driver and assistance-side activation of the brakes given satisfactory pedal feedback.

Abstract: A method for controlling a brake pressure booster with hydraulic brake boosting wherein the activation of an additional pressure source takes place upon exceeding a specified brake cylinder pressure threshold value. The threshold value lying between 50% and 100%, preferably between 70% and 80%, of a pressure limit value, from which the operating travel/brake pressure curve without additional brake pressure assistance has a knee point. Further upon exceeding a specified piston rod activation travel limit value, which lies at 20% to 100% of the available travel, preferably at 40% to 60% of the available travel.

Deactivation takes place on falling below a specified piston rod deactivation travel limit value. Based on selection of activation/deactivation criteria additional brake pressure boosting can be operational during braking maneuvers.
