Patent ID: 7040721

Claim:
A braking system for a motor vehicle, comprising: a hydraulic service braking system; an electric service braking system including wheel brakes to which braking pressure is applied when a brake pedal is operated; a control unit capable of changing a braking-force distribution between the electrical service braking system and the hydraulic service braking system; and a braking pressure modulator situated in the hydraulic service braking system for boosting the braking pressure acting on hydraulic brakes, wherein: the control unit is able to control an actuating element in the electric service braking system as well as the braking pressure modulator to change the braking-force distribution; the hydraulic service braking system includes a device via which a ratio between a pedal travel of the brake pedal and the braking pressure acting on the hydraulic wheel brakes is adjustable; and the control unit controls the device for adjusting the pedal travel in such a way that a ratio between the pedal travel and a total braking torque remains essentially constant during a change in the braking-force distribution.
