Abstract
A brake system for a motor vehicle includes on at least one wheel, an electric-regenerative brake and a friction brake that can be hydraulically actuated by a first generator of brake pressure using a fluid, wherein the friction brake can be connected via an actuatable inlet valve to the first generator of brake pressure and via a first actuatable outlet valve to a pressure accumulator, so that a volume of fluid applied by the first generator of brake pressure can be diverted via the first outlet valve into the pressure accumulator. The first generator of brake pressure can be connected to the pressure accumulator via a further hydraulic connection having a second actuatable outlet valve. A method for operating a brake system is also disclosed.

A brake system for a motor vehicle, which comprises, on at least one wheel, an electric-regenerative brake and a friction brake that can be hydraulically actuated by a first means for generating a brake pressure using a fluid, wherein the friction brake can be connected via an actuatable inlet valve to the first means for generating a brake pressure and via a first actuatable outlet valve to a pressure accumulator, so that a volume of fluid applied by the means for generating a brake pressure can be diverted via the first outlet valve into the pressure accumulator, wherein the first means for generating a brake pressure can be connected to the pressure accumulator via a further hydraulic connection having a second actuatable outlet valve, wherein a further actuatable valve is arranged between the first means for generating a brake pressure and the inlet valve, and the first means for generating a brake pressure can be connected to the pressure accumulator via a connection including both the further valve and the second outlet valve without acting on any friction brake.
A method for the open or closed-loop control of a brake system for a motor vehicle, which comprises, on at least one wheel, an electric-regenerative brake and a friction brake that can be hydraulically actuated by a first means for generating a brake pressure using a fluid, wherein the friction brake can be connected via an actuatable inlet valve to the first means for generating a brake pressure and via a first actuatable outlet valve to a pressure accumulator, so that a volume of fluid applied by the first means for generating a brake pressure can be diverted via the first outlet valve into the pressure accumulator, wherein during a regenerative braking process a volume of fluid applied by the first means for generating a brake pressure is discharged into the pressure accumulator via a second actuatable outlet valve, which is arranged in a further hydraulic connection between the means for generating a brake pressure and the pressure accumulator, wherein a further actuatable valve is arranged between the first means for generating a brake pressure and the inlet valve, and the first means for generating a brake pressure can be connected to the pressure accumulator via a connection including both the further valve and the second outlet valve without acting on any friction brake.
