ABSTRACT:
A hydraulic brake system for automotive vehicles with at least one load sensor (41) sensing the load condition of the vehicle and with at least one sensor (14, 15, 21, 22) associated wtih each vehicle axle for the detection of a braking parameter decisive for the braking operation. The measured values sensed are supplied to an electric evaluation circuit (18) which during a braking operation permanently computes suitable braking pressure values for the wheel brakes (3, 4) of the rear axle and delivers corresponding control signals to a braking pressure modulator (31, 53, 54). A braking force sensor (14, 15, 21, 22) is associated with at least one vehicle wheel (12, 13, 19, 20) of each vehicle axle. By measuring the braking force actually transmitted to the road surface via the electronic evaluation circuit (18), braking pressure is adjusted in the wheel brakes (3, 4) of the rear axle which allows for the existing marginal conditions such as allowance made for friction value variations of the brake pads of the wheel brakes (1, 2, 3, 4).
