Abstract
A brake system for automotive vehicles includes a pneumatic brake power booster with a control valve which is operable by a solenoid irrespective of the driver's wish. A control structure having a position controller which influences the position of the control valve provides the signals representative of voltage which are supplied to the solenoid. To achieve a comfortable, exactly controllable independent operation of the brake power booster, the position controller is provided by a comparator, connected upstream of which is a second summer wherein the output quantity of the deceleration controller is compared with a weighted signal representative of the speed of the armature. The output quantity of the deceleration controller corresponds to the position of the armature relative to the housing of the solenoid, and the travel signal which corresponds to the actual condition of the control valve represents the actual position of the armature relative to the housing of the solenoid.
