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.
A modulator for a pneumatic brake system of a vehicle, the modulator being connectable to a central module via a data bus and configured to reside in a valve block of the pneumatic brake system to combine with at least one solenoid valve in the valve block when the modulator is operatively disposed in the valve block, the modulator comprising at least one input for acquiring measured values and at least one output for actuating the at least one solenoid valve in the valve block, the modulator being configured to be a part of a control circuit and to first close the control circuit when the modulator is connected to the central module via the data bus to effect transmission of the measured values to the central module, and to receive control commands from the central module in the form of ON/OFF signals generated in the central module based on the measured values and operative to cause the modulator to actuate and deactuate the at least one solenoid valve via the at least one output.
