Abstract
A method for operating an electromechanically operable parking brake for motor vehicles with a driving motor furnished with a mechanical gearbox, uses a clutch pedal travel sensor to sense the position of a clutch pedal of the motor vehicle and a gear information sensor to find out whether the operator has selected a gear of the gearbox. Since the automated release operation of the parking brake is a safety-critical method, the signals of the clutch pedal travel sensor (18) and the gear information sensor (15) are checked in terms of their plausibility.

A method for operating an electromechanically operable parking brake for motor vehicles with a driving motor furnished with a manual-shift gearbox and a pedal-operated clutch, the vehicle having an operating element (7), an electronic control unit (6), to which are sent wheel rotational speed values from rotational wheel speed sensors (12, 13), at least one unit (1) for generating a brake application force, and brake devices (4) on at least one axle being applicable by the unit (1), the method comprising the steps of
- engaging the parking brake,
- detecting, by means of a gear information sensor, that a gear has been selected,
- detecting, by means of a travel sensor, that the clutch pedal (14) is being released,
- verifying the information received from the clutch pedal travel sensor (18) and the gear information sensor (15) for plausibility, and,
- if the signals are plausible, actuating the unit (1) to release the parking brake.
