Abstract

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.
