  • Utilizing a park brake system to improve the deceleration of a vehicle in the event of failure of the service brake system
    Patent number: 11332110
    Abstract: The invention concerns a method for utilizing a park brake system to improve the deceleration of a vehicle in the event of failure of the service brake system, the service brake system comprising a brake pedal (2) and at least one air supply circuit (40, 42, 44), the method including the steps of a) measuring the pressure in the air supply circuit, in particular in an air tank (40, 42) of the air supply circuit, and b) when the pressure in the air supply circuit falls below a certain value, switching the park brake system from a normal mode, wherein the park brake system is released, to an assistance mode. In the assistance mode, the park brake system assists the service brake system only if the brake pedal (2) is depressed until reaching a threshold position different from a rest position.
