摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a brake system for a motor vehicle, wherein the brake system for a motor vehicle is hydraulically associated with wheels FL, FR of a first vehicle axle VA and wheels RL, RR of a second vehicle axle HA wheel brakes 8a to 8d, electrically actuable inlet valve 6a to 6d for each wheel brake 8a to 8d for setting wheel-specific brake pressures and an electrically actuable outlet valve (7a to 7d), a first electrically controllable pressure providing device 5 connected to the brake supply line 13 to which the wheel brakes 8a to 8d are connected, a second electrically controllable pressure providing device 5 connected to the brake supply line 13 An electrically controllable pressure providing device ( 2 ), a first electrical device ( 100 ) having electrical and/or electronic elements controlling the first pressure providing device ( 5 ), and a second pressure providing device ( 2 ) controlling A first electrical partition wall (A) and a second electrical partition wall (B) having a second electrical device (110) having electrical and/or electronic elements are provided which are electrically independent of each other, a first pressure providing device (5) and a second electrical device 100 is associated with the first electrical bulkhead A and includes a second pressure providing device 2 , a second electrical device 110 and inlet and outlet valves 6a to 6d, 7a to 7d is associated with the second electrical bulkhead B, and the inlet and outlet valves 6a to 6d, 7a to 7d are controlled by the second electrical device 110 . The invention also relates to methods for operating said brake system.
