<p>A brake system for motor vehicles, which brake system can be actuated both by the vehicle driver and also independently of the vehicle driver in a“brake by wire”operating mode, is preferentially operated in the“brake by wire”operating mode, and can be operated in at least one fall-back operating mode in which only operation by the vehicle driver is possible. The brake system has inter alia an electrohydraulic pressure generating device (5) which outputs a brake system pressure, and a pressure modulation unit which has one inlet valve (6a-6d) and one outlet valve (7a-7d) per wheel brake (8, 9, 10, 11) for setting wheel-specific brake pressures derived from the brake system pressure, wherein the inlet and outlet valves (6a-6d, 7a-7d) output or transmit the brake system pressure when in the non-actuated state.</p> |
