Air treatment system and method for securely releasing a parking brake system
First Claim
1. An air treatment system for supplying a commercial vehicle brake system with compressed air, having a compressed air outlet which is provided for supplying a parking brake system and which is intended for ventilating at least one spring-loaded cylinder of a parking brake to release the parking brake, the system comprising:
- an electrically actuable valve, by which a supply of the compressed air outlet with compressed air is preventable;
an electrically evaluatable indicator signal, which is made available when a person for driving the commercial vehicle is present;
wherein the electrically actuable valve operates to prevent the supply of the compressed air outlet with compressed air when the indicator signal is absent.

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.

13. A method for ventilating at least one spring-loaded cylinder of a parking brake to release the parking brake of a commercial vehicle brake system, which system is supplied with compressed air by an air treatment system, the air treatment system having a compressed air outlet provided for supplying the parking brake system, the method comprising the acts of:
-
when a person for driving the commercial vehicle is present, making available an electrically evaluatable indicator signal; and
preventing a supply of the compressed air outlet with compressed air via an electrically actuable valve when the indicator signal is absent. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
