Abstract
An electrohydraulic multi-circuit power brake system for autonomous driving. The power brake system includes a piston-cylinder unit for each brake circuit, using which the brake circuits are connected to a common power brake pressure generator. In the event of a failure of the power brake pressure generator, the power brake system can be actuated with a hydraulic pump of a slip control system of the vehicle brake system.

1-9. (canceled)
A hydraulic multi-circuit power brake system, comprising:
- a plurality of brake circuits, each brake circuit of the plurality of brake including at least one hydraulic wheel brake and a first hydraulic power brake pressure generator;
- and
- a second piston-cylinder unit for each brake circuit, wherein first piston sides of pistons of the second piston-cylinder units communicate with the first hydraulic power brake pressure generator and second piston sides of the pistons of the second piston-cylinder units each communicate with one of the brake circuits.
