Abstract

A brake system comprises a first electrohydraulic open-loop and closed-loop control unit. The first electrohydraulic control unit comprises a master brake cylinder actuatable by a brake pedal; a first electrically controllable pressure-providing device; and an electrically controllable pressure-modulating device sets wheel-specific brake pressures for the wheel brakes. The electrically controllable pressure-modulating device has at least one electrically actuatable inlet valve for each wheel brake. A first pressure-medium reservoir for supplying the first electrohydraulic control unit with pressure medium is arranged on the first electrohydraulic control unit. The brake system also comprises a second electrohydraulic open-loop and closed-loop control unit, which comprises a second electrically controllable pressure-providing device for actuating at least some of the wheel brakes and electrically actuatable valves. A second pressure-medium reservoir for supplying the second electrohydraulic control unit with pressure medium is provided, the second pressure-medium reservoir being arranged on the second electrohydraulic control unit.
