Abstract
A hydraulic brake system for a motor vehicle with redundant braking pressure regulation is presented. The brake system comprises a first functional unit having at least one first electrical braking pressure generator which is designed to generate a braking pressure at each of a plurality of wheel brakes, and further having a valve assembly per wheel brake. The valve assembly can be actuated for braking pressure regulation at the corresponding wheel brake in order to couple a first wheel brake associated with the valve assembly either to the first braking pressure generator or to an unpressurized reservoir for hydraulic fluid. The brake system also comprises a second functional unit having at least one second electrical braking pressure generator which is designed to generate a braking pressure at each of a subset of the wheel brakes. The output of the second braking pressure generator is arranged downstream, as seen from the first braking pressure generator, of the valve assembly associated with the corresponding wheel brake. The second functional unit is also designed to perform braking pressure regulation at each wheel brake of the subset redundantly in relation to the first functional unit.
