Hydraulic Vehicle Braking System with Electromechanical Actuator, and Method for Operating Such a Hydraulic Vehicle Braking System

摘要

A hydraulic vehicle braking system comprises a master cylinder having at least one piston displacably accommodated therein, a mechanical actuator that is coupled, or can be coupled, to a brake pedal for actuating the piston, and an electromechanical actuator. The electromechanical actuator is likewise provided for actuating the piston and can be activated, at least for boosting or generating brake force, when the brake pedal is actuated. Furthermore, a valve arrangement is provided, which has a first valve per wheel brake for selectively uncoupling the wheel brake from the master cylinder, and a second valve for selectively reducing the brake pressure at the wheel brake. The valve arrangement can be controlled at least within the framework of an ABS control mode.

1. Hydraulic vehicle braking system (100; 400; 500), comprising:
a master cylinder (136) having at least one piston (140) displaceably accommodated therein; a mechanical actuator (162), coupled or couplable to a brake pedal, for actuating the piston (140); an electromechanical actuator (158) for actuating the piston (140), the electromechanical actuator (158) being drivable at least for brake force boosting or brake force generation upon an actuation of the brake pedal; and a first valve arrangement (300), which per wheel brake (116) has a first valve (304) for selectively uncoupling the wheel brake (116) from the master cylinder (136) and a second valve (308) for selectively reducing the brake pressure at the wheel brake (116), the first valve arrangement (300) being drivable at least in the context of an ABS control mode.
