Abstract
A “brake-by-wire” type brake system for a motor vehicle, having a brake pressure sensor which can be activated by a brake pedal of a pedal unit and can be connected to wheel brakes of the vehicle outside the “brake-by-wire” operating mode, having a pressure source which can be actuated by an electronic control unit and can be connected to the wheel brakes of the vehicle in the “brake-by-wire” operating mode, and having a pedal travel simulator which interacts with the brake pedal and is formed by at least one simulator element, and a restoring force which acts on the brake pedal independently of the actuation of the pressure source can be simulated in the “brake-by-wire” operating mode. In order to provide a simpler and more cost-effective “brake-by-wire” type brake system, a force/travel characteristic of the pedal travel simulator is provided in a controllable fashion.
