Abstract
A slip-controlled hydraulic vehicle brake system includes a first hydraulic pump configured to draw brake fluid out of wheel brakes or out of a hydraulic accumulator connected to the wheel brakes. The brake system also includes two further hydraulic pumps configured to be connected to a brake master cylinder for a rapid pressure buildup. To pump against a high brake pressure while the vehicle brake system is actuated, only the first hydraulic pump is used, while the other two hydraulic pumps are separated from the brake master cylinder and run 'at idle' at the same time. The necessary mechanical driving power of the hydraulic pumps is thereby reduced, and a very rapid pressure buildup is nevertheless possible.
