Abstract

A brake system, including four hydraulically actuatable wheel brakes. Each wheel brake is assigned in each case one outlet valve which is closed when electrically deenergized. Each wheel brake is assigned in each case one inlet valve which is open when electrically deenergized. The brake system furthermore includes a simulator which is actuatable by a brake pedal, wherein two pressure provision devices are provided for actively building up pressure in the wheel brakes, two brake circuits are hydraulically formed, wherein, in each brake circuit, in each case one pressure provision device is hydraulically connected to two wheel brakes, and wherein two separate on-board electrical systems are provided, and wherein each pressure provision device is fed in each case by one of the two on-board electrical systems.
