Claim 0:
1. A brake system for a two-axle vehicle, comprising:
a master brake cylinder to which a brake actuating element is connected in such a way that a target vehicle deceleration desired by a driver of the vehicle is input by actuating the brake actuating element;
at least one brake circuit which is connected to the master brake cylinder, each of the at least one brake circuit having a respective front wheel brake cylinder, a respective rear wheel brake cylinder, a respective front wheel inlet valve associated with the respective front wheel brake cylinder, a respective front wheel outlet valve associated with the respective front wheel brake cylinder, a respective rear wheel inlet valve associated with the respective rear wheel brake cylinder, a respective rear wheel outlet valve associated with the respective rear wheel brake cylinder and a respective accumulator chamber downstream of the respective front wheel outlet valve and the respective rear wheel outlet valve; and
a control device which, in response to an actively input target vehicle deceleration unequal to zero, is able to discern or effect that a generator operation of at least one electric motor of the vehicle is able to effect a recuperative vehicle deceleration that is equal to the input target vehicle deceleration, and which is configured to optionally displace a brake fluid pressed out of the master brake cylinder via the respective rear wheel outlet valve into the respective downstream disposed accumulator chamber by opening the respective rear wheel outlet valve;
wherein, when the respective front wheel outlet valve is kept closed or closed, the control device is configured to optionally increase and limit a brake pressure prevailing in the respective associated front wheel brake cylinder to an accumulator chamber pressure actively prevailing in the respective accumulator chamber of the same brake circuit by keeping open or opening the respective front wheel inlet valve.
