Abstract:
A device for controlling at least one operating-dynamics variable of a vehicle in a closed loop, comprising:a braking system including at least one brake circuit and a reservoir for accommodating a braking medium, the at least one brake circuit including wheel brake cylinders, a first valve arrangement on an output side and a second valve arrangement on an input side, the first valve arrangement being connected to the wheel brake cylinders which are assigned to the at least one brake circuit, the second valve arrangement being connected to the reservoir; and a system determining a particular cylinder of the wheel brake cylinders which exhibits a highest brake pressure, wherein the system adjusts a particular brake pressure of the particular cylinder in response to a driver-independent brake actuation, the particular brake pressure being adjusted by driving the second valve arrangement, and wherein the system drives the first valve arrangement which is assigned to a respective cylinder of the wheel brake cylinders, the first valve arrangement being driven to adjust a further brake pressure of at least one remaining cylinder of the wheel brake cylinders, and further comprising: a first arrangement determining volumetric requirement values for the wheel brake cylinders which are assigned to the at least one brake circuit, wherein the system performs at least one of the following functions: driving the second valve arrangement as a function of a sum of the volumetric requirement values, and driving the first valve arrangement of the at least one remaining cylinder as a function of a particular value of the volumetric requirement values of a corresponding wheel brake cylinder of the at least one remaining cylinder.
