Embodiment Construction

[0016] A circuit diagram of a hydraulic brake system is schematically shown in FIG. 1 . The hydraulic braking system has wheel brakes 2 on the first axle, the front axle, which can be applied with pressure during service braking via hydraulic lines 9 . In order to control the desired braking deceleration and to implement anti-lock brake regulation (ABS), the wheels of the front axle are assigned wheel speed sensors 12, the output signals of which are fed to the electronic control and regulation unit (ECU) 5 . The electronic control and regulating unit 5 is assigned to the service brake system. Wheel brakes 3 are also arranged on the second, ie rear, axle, which can be acted upon with pressure during service braking via the second hydraulic line 10 . The rotational speeds of the wheels of the rear axle are detected by wheel rotational speed sensors 13 and supplied to the aforementioned electronic control and regulating unit 5 . Furthermore, the wheels of the rear axle have e...

Abstract

The invention relates to a method for operation of an electromechanically-operated parking brake for motor vehicles with a drive motor provided with a mechanical manual gearbox, essentially comprising an operating element, an electronic controller, provided with wheel rotational speed values from wheel rotational speed sensors, at least one unit for generation of an application force and braking devices applied by the unit on at least one axle, whereby the electronic controller operates the unit, after recognition of a starting procedure for the motor vehicle, in the manner of a release process for the parking brake. According to the invention, a release process for the parking brake, after recognition of a starting process, may be configured to be as convenient as possible, whereby, on recognition of a starting process and before carrying out the release process for the parking brake, the electronic controller 6a operates the unit 1 such as to reduce the application force to a slope-dependent holding force.

Description

technical field [0001] The invention relates to a method for actuating an electromechanically actuated parking brake of a motor vehicle having a drive motor provided with a mechanical shift transmission, the parking brake being essentially composed of an actuating element, An electronic control unit, at least one unit for generating a pressing force, and a brake device on at least one axle that can be applied by the unit, to which wheel speed values ​​are fed from wheel speed sensors, wherein The electronic control unit controls the unit to carry out a release process of the parking brake after a drive-off process of the motor vehicle has been detected. Background technique [0002] DE 103 24 446 B3 discloses a method for controlling a braking system equipped with an electric parking brake. In this previously disclosed method, a first time interval is determined from the start of the engagement action to the clutch response time, which corresponds to the so-called clutch co...
