| 摘要 |
The invention relates to a brake system for a motor vehicle for actuating hydraulically actuatable wheel brakes (8a, 8b, 8c, 8d). The brake system comprises a first electrohydraulic open-loop and closed-loop control unit (60). The first electrohydraulic open-loop and closed-loop control unit comprises: a master brake cylinder (2) that can be actuated by means of a brake pedal (1); a first electrically controllable pressure-providing device (5); and an electrically controllable pressure-modulating device (61) for setting wheel-specific brake pressures for the wheel brakes, the electrically controllable pressure-modulating device having at least one electrically actuatable inlet valve (6a-6d) for each wheel brake. A first pressure-medium reservoir (4) for supplying the first electrohydraulic open-loop and closed-loop control unit (60) with pressure medium is arranged on the first electrohydraulic open-loop and closed-loop control unit (60). The brake system also comprises a second electrohydraulic open-loop and closed-loop control unit (160), which comprises a second electrically controllable pressure-providing device (105) for actuating at least some of the wheel brakes (8a, 8c) and electrically actuatable valves (145a, 145b, 146a, 146b, 147a, 147b). A second pressure-medium reservoir (104, 204) for supplying the second electrohydraulic open-loop and closed-loop control unit (160) with pressure medium is provided, the second pressure-medium reservoir being arranged on the second electrohydraulic open-loop and closed-loop control unit (160). |
