Abstract
A vehicle air system has an air dryer which is periodically regenerated by reverse flow of dry air. The regeneration threshold is variable, and determined according to the operating state of the vehicle. The operating state is in turn determined from easily measurable vehicle status parameters, preferably in the form of on/off or in/out signals.
