A brake system for a motor vehicle and a related method includes a hydraulic service brake system, having a brake booster and is operable via a brake operating element, an electric machine, operable as a generator to brake the motor vehicle, and an electromechanical braking device. A setpoint braking torque is determined as a function of a brake pedal travel. The hydraulic service brake system has an idle travel between the brake operating element and a master brake cylinder, in which no braking torque is generated by the vehicle brake system. In the range of the idle travel, the setpoint braking torque is generated by the generator and/or the electromechanical braking device, and a portion of the electromechanical braking device in the setpoint braking torque is modulated as a function of a portion of the generator in the setpoint braking torque so that variations of the generator portion are compensated. |
