Abstract
In a method for operating a braking system of a vehicle by limiting brake pressure buildup during an activation of a brake actuating element, the rear wheel outlet valves of the rear wheel brake cylinders, which are respectively associated with a rear wheel of the vehicle, are controlled, at least temporarily, into an open state during the activation of the brake actuating element, and the front wheel inlet valves of the front wheel brake cylinders, which are respectively associated with a front wheel of the vehicle, are controlled, at least temporarily, into a closed state during the control of the rear wheel outlet valves into the open state.

A method for operating a braking system of a vehicle, comprising:
- limiting, at least temporarily, a brake pressure buildup in at least one brake circuit of the braking system to a response pressure of a storage volume of the at least one brake circuit during an activation by a driver of the vehicle of a brake actuating element connected to a master brake cylinder of the braking system, by controlling at least one wheel outlet valve of at least one wheel brake cylinder of the at least one brake circuit into an open state;
- wherein rear wheel outlet valves of rear wheel brake cylinders, which are respectively associated with rear wheels of the vehicle, are controlled, at least temporarily, into the open state during the activation of the brake actuating element, and the front wheel inlet valves of the front wheel brake cylinders, which are respectively associated with front wheels of the vehicle, are controlled, at least temporarily, into a closed state during the control of the rear wheel outlet valves into the open state.
A control device for a braking system of a vehicle, comprising:
- an actuating device, with the aid of which at least one wheel outlet valve of a wheel brake cylinder of at least one brake circuit of the braking system is controlled into an open state, taking into account at least one provided sensor signal with regard to an activation intensity of an activation by a driver of the vehicle of a brake actuating element which is connected to a master brake cylinder of the braking system, whereby a brake pressure buildup at least in the at least one brake circuit is limited, at least temporarily, during an activation of the brake actuating element to a response pressure of a storage volume of the at least one brake circuit;
- wherein the actuating device is configured for controlling, at least temporarily, during the activation of the brake actuating element, rear wheel outlet valves of rear wheel brake cylinders which are associated with respective rear wheels of the vehicle, into the open state with the aid of at least one first control signal, and during the provision of the at least one first control signal to the rear wheel outlet valves, for controlling, at least temporarily, the front wheel inlet valves of the front wheel brake cylinders which are associated with respective front wheels of the vehicle, into a closed state with the aid of at least one second control signal.
