Abstract

An electropneumatic control arrangement for an automatic vehicle level control system, particularly of a commercial vehicle, includes at least; a solenoid valve unit having at least two electropneumatic solenoid valves, a compressed air inlet for infeeding compressed air, at least one compressed air connection for at least one air bellows and electrical control inputs, and an electronic control unit for actuating the solenoid valve unit. The electronic control unit comprises control outputs for electrically connecting to the control inputs of the solenoid valve unit. A plug connector is configured on the housing of the solenoid valve unit, in which the electrical control inputs are disposed, and a plug connector is provided on the housing of the electronic control unit, in which the control outputs are disposed. The plug connectors are mechanically plugged into each other.
