Abstract
The disclosure is directed to a method for safe emergency stopping of a utility vehicle having an electronically controllable pneumatic brake system with spring brake cylinders on at least one axle. The electronically controllable pneumatic brake system has a service brake system and a first redundancy system. In the event of a first fault in the service brake system, the vehicle is braked by the redundancy system. The electronically controllable brake system furthermore has an unthrottled ventilation path, and a ventilation path, for the ventilation of the spring brake cylinders. The method includes determining a second fault in the redundancy system, and, in response, automatically throttling ventilation of at least one of the spring brake cylinders via the throttled ventilation path to effect slow, safe stopping of the vehicle.
