Brake system e.g. break-by-wire system, for motor vehicle i.e. small car, has hydraulic brake system comprising simulator unit to extract hydraulic fluid from brake system to provide driver about pedal sensation at brake pedal

摘要

The system has a driving dynamics control system (24) covered with a main brake cylinder by one of hydraulic lines (20, 22) to conduct hydraulic fluid into a wheel brake (VL). A generator brake system (28) provides a braking action by controlling a generator (32). A hydraulic brake system (8) comprises a simulator unit (36b), which is designed to extract the hydraulic fluid from the hydraulic brake system and to return back into the hydraulic brake system to provide a driver about pedal sensation at a brake pedal (10). A pedal sensation is independent of the brake systems (8, 28). An independent claim is also included for a method for operating a brake system of a motor vehicle.
