Abstract

The disclosure relates to a hydraulic brake system for a highly automated or autonomous vehicle which includes three pressure generators which provide sufficient braking force even in a case of a fault. Two of the pressure generators are assigned in a redundant manner to one axle and a modulation unit is configured to hydraulically connect the two pressure generators to the wheel brakes of the first axle, and to perform individual brake pressure modulation in the wheel brakes. The third pressure generator is hydraulically separate from the other pressure generators, and another modulation unit is configured to hydraulically connect the third pressure generator to wheel brakes of another axle, and to perform individual brake pressure modulation in the wheel brakes.
