Abstract
An air treatment system and method are provided for supplying a brake system of a utility vehicle with compressed air. The air treatment system includes a compressed air outlet that is used for feeding a parking brake system, more specifically for ventilating at least one spring-loaded cylinder of a parking brake and thus for releasing the parking brake. An electrically actuated valve, by which the compressed air outlet can be prevented from being supplied with compressed air, is provided, along with an indicator that can be electrically evaluated to determine if a person is present for driving the vehicle. The electrically actuated valve prevents the compressed air outlet from being supplied with compressed air when the indicator is not provided.
