Elelctronically controllable brake actuation system

Abstract

The present invention relates to an electronically controllable brake actuation system for automotive vehicles, including a master brake cylinder operable by way of an actuating pedal, braking pressure generators actuatable by an electronic control unit and directly connected to the wheel brakes of the vehicle, the braking pressure generators being connectable to the master brake cylinder by way of hydraulic connections closable by valve assemblies, at least one sensor device to identify the driver's wish for deceleration, and at least one simulator chamber which interacts with the master brake cylinder. To improve the operation of such a system, in particular the dynamics of the braking pressure generators, and to shorten the response time of the entire system in addition, the present invention proposes that the valve assemblies be configured as solenoid valves which are actuatable by the electronic control unit with time delay, and low-pressure accumulators are connected to the pressure chambers of the braking pressure generators to be connected to the wheel brakes in the release position of the braking pressure generators.
