A modulator for a vehicle brake system connected to a central module via a data bus, includes at least one input for capturing measured values and at least one output for controlling at least one electromagnetic valve. A control circuit for actuating the valve is connected by the bus such that the measured values are transmitted to the central module. Control commands for actuating the valve are calculated from the measured values in the central module, and are transmitted via the data bus to the modulator so that the it selects the valve as a function of the commands. A vehicle system has at least two modulators and a central module integrated in a modulator. The modulator can be used as a pressure modulator in an air suspension system or in an electronic braking system or in a conventional braking system with an anti-lock braking system or an electronic stability program.
