Abstract
A controller for controlling a pneumatic control valve (PCV) in a central tire inflation system (CTIS). The controller includes an electronic processor having an electrical input for receiving a supply-side pressure signal. The electronic processor is configured to control a first control valve (VINSS) to generate a pneumatic control signal for changing an operating state of a pneumatic control valve (PCV). The electronic processor also monitors the supply-side pressure signal and identifies a change in the operating state of the pneumatic control valve (PCV) in dependence on a change in the supply-side pressure. The electronic processor is configured to output a first valve close signal upon determining that the pneumatic control valve (PCV) has changed operating state. Also provided is a CTIS incorporating a controller; to a vehicle; and to a method of controlling a pneumatic control valve (PCV).
