BRAKING SYSTEM FOR A MOTOR VEHICLE
First Claim
1. A hydraulic brake system for a motor vehicle comprising:
- a first electrically controllable pressure source which supplys a brake pressure for operating wheel brakes;
an electrically controllable pressure modulation device for setting wheel-specific brake pressures for the wheel brakes with an inlet valve that can be operated electrically and an outlet valve that can be operated electrically for each wheel brake;
a second electrically controllable pressure source for supplying a brake pressure for operating the wheel brakes comprising a motor-pump assembly with an at least dual circuit hydraulic pump and at least one low-pressure reservoir, whereby the low-pressure reservoir is connected to an output port of at least one outlet valve; and
a first electrical power supply unit and a second electrical power supply unit that is independent of the first electrical power supply unit, whereby the first pressure source can be supplied with electrical energy by the first power supply unit, the second pressure source can be supplied with electrical energy by the second power supply unit and the pressure modulation device can be supplied with electrical energy by the first power supply unit and the second power supply unit.

Abstract
A braking system for a motor vehicle comprises a first and second electrically controllable pressure source for providing a brake pressure for actuating the wheel brakes. An electrically controllable pressure modulation device sets brake pressures that are individual to each of the wheel brakes, said device having electrically actuatable inlet valves and outlet valves for each wheel brake. The second pressure source comprises a motor-pump unit and at least one low-pressure accumulator. The low-pressure accumulator is connected to an output connection of at least one outlet valve. A first and a second energy supply unit for the braking system are independent from one another. The first energy supply unit supplies the first pressure source with energy. The second energy supply unit supplies the second pressure source with energy. The pressure modulation device is supplied with energy by the first energy supply unit and by the second energy supply unit.
