  • Patent number: 12715414
    Abstract: A method of operating a compressed air system of a vehicle is disclosed. The compressed air system comprises a purge valve controllable to an open state to vent air from the compressed air system at a location between an air compressor and an air processing element. The method comprises the step of controlling the purge valve to the open state if data is indicative of at least one of a preceding, an ongoing and an upcoming accumulation of matter in at least one component of the compressed air system and maintaining the purge valve in the open state until the air pressure in the compressed air system declines below a threshold pressure. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, a compressed air system, and a vehicle.
