Embodiment Construction
[0042] figure 1 A first exemplary embodiment of a brake system according to the invention for a motor vehicle with four hydraulically actuatable wheel brakes 8 a - 8 d is shown very schematically in FIG. According to the example, the wheel brake 8a is assigned to the left rear wheel (RL), the wheel brake 8b is assigned to the right rear wheel (RR), the wheel brake 8c is assigned to the left front wheel (FL), and the wheel brake 8d is assigned to the right front wheel (FR) . That is to say, wheel brakes 8 a , 8 b are assigned to rear axle HA and wheel brakes 8 c , 8 d are assigned to front axle VA. Other assignments of wheel brakes 8 a - 8 d to wheels (FL, FR, RL, RR) are conceivable, but a "black and white" assignment is particularly advantageous, as will be explained below.
[0043] The brake system comprises an electrically controllable first pressure supply device 5 , an electrically controllable second pressure supply device 2 , a pressure medium reservoir 4 at atmospher...

The invention relates to a braking system for a motor vehicle, comprising: hydraulically actuatable wheel brakes (8a-8d), which are assigned to the wheels (FL, FR) of a first axle (VA) and to a second vehicle axle Wheels (RL, RR) of axle (HA); respective electrically actuatable inlet valve (6a‑6d) and electrically actuatable outlet valve (7a‑7d) for each wheel brake (8a‑8d) for regulating wheel-specific brake pressure; an electrically controllable first pressure supply device (5), which is connected to the brake supply line (13) to which the wheel brakes (8a‑8d) are connected; electrically controllable a controlled second pressure supply device (2), which is connected to the brake supply line (13); a first electrical device (100) with electrical and / or electronic components, which controls the first pressure supply device (5); and a second electrical device (110) with electrical and / or electronic components, which controls the second pressure providing device (2), wherein a first electrical partition (A) and a second electrical partition (B) electrically independent of each other are provided ), the first pressure supply device (5) and the first electric device (100) are assigned to the first electric partition (A), the second pressure supply device (2), the second electric device (110) and the inlet valve (6a- 6d) and the outlet valve (7a-7d) are assigned to the second electrical section (B), the inlet valve (6a-6d) and the outlet valve (7a-7d) are controlled by the second electrical device (110). The invention also relates to a method for operating the brake system.
Description
technical field [0001] The invention relates to a brake system for a motor vehicle and to a method for operating the brake system. Background technique [0002] A brake system with two electrically controllable pressure sources and a brake master cylinder is known from DE 10 2013 217 954 A1 for a motor vehicle with four hydraulically actuatable wheel brakes. In addition to the wheel-specific inlet and outlet valves, the brake system also includes a circuit isolating valve and four isolating valves for isolating the brake master cylinder and the electrically controllable pressure source from the inlet valves. In its disconnected position, the circuit separation valve separates the brake system into two brake circuits, wherein the first brake circuit is assigned two front wheel brakes and the second brake circuit is assigned two rear wheel brakes . In the first brake circuit only the first pressure source and in the second brake circuit only the second pressure source build ...
