MOTOR VEHICLE BRAKING SYSTEM

摘要

The invention relates to a "Brake-by-wire" braking system comprising a main cylinder (3) and wheel braking circuits (I, II) associated thereto and two brake booster pressure fluid circuits which are completely separated from said wheel braking circuits wheel braking circuits. In order to use a pressure control valve (34) associated with the first brake booster pressure fluid circuit for controlling a pressure in an intermediate space (21) not only by pressing on a pedal but also electrically, means (39, 40) for electrically controlling the intermediate space (21) pressure are provided with the pressure control valve (34).
