Brake-by-wire actuator for automobile braking system has brake pedal decoupled from force reactions in braking system during brake-by-wire operating mode

摘要

The brake-by-wire actuator has at least one simulator (2) acted on by a brake pedal (1), with an actuation sensor (3) supplying a signal to an electronic control unit (4), for corresponding control of a pressure source, coupled to a distributor (10) for the braking force for the individual wheel brakes (16). A free travel path (a) is provided between the brake pedal and a downstream actuation component for muscle power braking, for mechanical decoupling of the brake pedal from force reactions in the braking system during the brake-by-wire operating mode.
