Abstract
For a vehicle equipped with a self-braking system (for example, ASR, ESP, FDR, EBS), a service brake, a parking brake, and at least one associated pressure sensor for detecting at least one pressure in the vehicle brake circuit, the brake circuit comprising a compressed-air circuit, a process to prevent the vehicle from rolling away includes determining whether a pressure in the compressed-air circuit from which the parking brake is fed is below a release threshold, and operating the service brake if the pressure in the compressed-air circuit is below the release threshold.
