METHOD FOR ADJUSTING THE CLAMPING FORCE EXERTED BY A PARKING BRAKE, REGULATING AND CONTROL APPLIANCE FOR CARRYING OUT SAID METHOD, AND VEHICLE PARKING BRAKE COMPRISING SUCH A CONTROL APPLIANCE

摘要

In a method for adjusting the clamping force exerted by a parking brake, which force is applied by an electric-motor braking apparatus and a hydraulic braking apparatus, the electric braking motor impinging upon a brake piston of a hydraulic wheel brake unit of the hydraulic braking apparatus, for the case in which the pre-pressure existing in the hydraulic braking apparatus exceeds a threshold pressure value, an inlet valve in the braking circuit of the hydraulic braking apparatus is closed, and the target braking force is established by actuation of the electric-motor braking apparatus.
