Abstract
A multi-circuit, hydraulically open brake system includes a first pressure generator assigned to a main system with a first energy supply and a first evaluation and control unit (ECU), and is connectable via a first shut-off valve to wheel brake(s) of a first brake circuit and via a second shut-off valve to wheel brake(s) of a second brake circuit. A second pressure generator is assigned to a secondary system which includes a second energy supply and a second ECU, and is connectable via a third shut-off valve to wheel brake(s) of the first brake circuit and via a fourth shut-off valve to wheel brake(s) of the second brake circuit. The second ECU controls the second pressure generator. Components of the modulation unit for individual brake pressure modulation are assigned to the main system, and the components are controlled by the first ECU and are supplied by the first energy supply.
