Disclosed is a method for operating an electromechanically operable parking brake for motor vehicles with a driving engine furnished with a mechanical gear box, being substantially composed of an operating element, an electronic control unit, to which are sent wheel rotational speed values from wheel rotational speed sensors, at least one unit for generating a brake application force, and brake devices on at least one axle being lockable by the unit, with the electronic control unit actuating the unit after detection of a starting maneuver of the motor vehicle in the sense of a release operation of the parking brake. In order to render a release operation of the parking brake as comfortable as possible after detection of a starting maneuver of the motor vehicle, the method at issued arranges that the electronic control unit () actuates the unit () in order to reduce the brake application force to an inclination-responsive holding force when a starting maneuver is detected and before the release operation of the parking brake is performed.

Method for operation of a braking system for a motor vehicle

An electromechanically actuable parking brake for motor vehicles is disclosed. The brake includes at least one electromechanical actuator whose rotational movement is converted into a translational movement by an actuating unit, and which moves at least one brake element in such a way that at least one brake lining which is connected to the brake element is pressed with a locking force against a rotor which is connected to a motor vehicle wheel, wherein the current consumption of electromechanical actuator when the parking brake is engaged and/or released can be acquired. Furthermore, a method for operating the electromechanically actuable parking brake is also disclosed.

Method for the operation of an electromechanically operable parking brake

Disclosed is a method for operating an electromechanically operable and/or electromechanically lockable parking brake for motor vehicles having an operating element, an electronic control unit, to which are sent wheel speed values from wheel speed sensors, at least one unit for generating a brake application force, and electromechanically lockable brake devices on at least one axle, with the brake devices being adapted to be applied by the unit. Also disclosed is a parking brake for motor vehicles for implementing the method. When wheel speed values are missing, the operator decides whether a static operating mode is assigned to the parking brake, i.e. that the brakes are applied with maximum allowable force upon actuation of the operating element, and release is possible only by means of new actuation of the operating element, or decides whether a dynamic operating mode is assigned, i.e. the brake application force is exclusively developed and provided during actuation of the operating element.

Device and method for operating a motor-vehicle parking brake

The invention relates to a method for determining that a motor vehicle is driving uphill or downhill, and for this purpose the vehicle acceleration a is determined by means of differentiation from V and compared with a longitudinal vehicle acceleration a determined by a sensor. The method checks whether there is a deviation from normal driving by monitoring whether &verbar;a &minus;a &verbar; is greater than a threshold value SL. In addition a deviation time t is determined, within which the deviation from normal driving prevails without interruption; the deviation time t is monitored to determine whether a minimum time value T is exceeded in order to conclude that the vehicle is climbing or descending a slope when t is greater than T . The invention also relates to a device that uses a digital logic with a counter to measure the times t, t , t and t , with one digit of the logic corresponding to a defined time unit.

Method for determining that a motor vehicle is climbing or descending a slope

For controlling a traction slip control system with brake and motor management, motor regulating signals (m) are derived from electrical signals indicative of the brake pressure or which influence the brake pressure. Preferably, a brake pressure pattern (p[t]) is formed taking into account the pressure build-up and pressure decrease characterics of the wheel brakes or of the entire system as a basis for computing the motor regulating signals (m).
