A controller (15, Fig.1B) for controlling a pneumatic control valve (PCV, Fig.1A) in a central tyre inflation system (CTIS) where the controller includes an electronic processor having an electrical input for receiving a supply-side pressure signal and the electronic processor is electrically coupled an electronic memory device having instructions stored therein; where 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 and the electronic processor also monitors the supply-side pressure signal and identifies a change in the operating state of the pneumatic control valve in dependence on a change in the supply-side pressure; wherein the electronic processor is configured to output a first valve close signal upon determining that the pneumatic control valve has changed operating state. The present disclosure also relates to a CTIS incorporating a controller; to a vehicle comprising the CTIS; and to a method of controlling a pneumatic control valve. |
