Abstract: A safety park brake system of a vehicle is disclosed. The safety system comprises a pneumatic park brake, a park brake electronic unit, a controller, an air brake sub-system in air communication with the pneumatic park brake, and a compressor. The compressor is configured to provide pressurized air to the air brake sub-system through a discharge line arranged between the compressor and the air brake sub-system. The controller is configured to receive a park brake request, detect an error associated with a failure in the park brake electronic unit, and impede inflow of pressurized air into the air brake sub-system. The safety park-brake system is configured to control discharge of air from the air brake sub-system to thereby achieve a drop in air pressure. The pneumatic park brake is configured to automatically apply once the air pressure in the air brake sub-system drops below a predetermined threshold.
