Claim 7:
8. An electrohydraulic brake system of a vehicle operable both in a manual and in an autonomous driving mode, comprising:
a first and a second hydraulic brake circuit hydraulically decouplable from one another by a circuit-separating valve, each being assigned to enable at least one respective wheel brake of the vehicle;
an actuating cylinder actuatable by a brake pedal;
a hydraulic pressure source controllable by an electronic open-loop and/or closed-loop control unit by a pressure in which the at least one wheel brake of one of the first and second hydraulic brake circuits is controllable in an autonomous driving mode of the vehicle;
an actuating valve to produce a hydraulic connection between the actuating cylinder and two or more wheel brakes assigned to a common brake circuit of the first and second hydraulic brake circuits, and
a brake pedal actuator or a driver by which the brake pedal is movable into an at least partially actuated position, wherein
the wheel brakes of the vehicle are assigned to one outlet valve that is controllable by the electronic open-loop and/or closed-loop control unit,
in the opened state, the one outlet valve produces a hydraulic bypass of brake fluid into a brake fluid vessel, and
the brake pedal is configured to be mechanically coupled and decoupled to an accelerator pedal such that, in the autonomous driving mode of the vehicle, the accelerator pedal is likewise held in an actuated position.
