An automatic braking device for a vehicle and a method for automatically braking a vehicle. The vehicle is automatically braked using at least one friction brake of the vehicle in such a way that a brake force that is effectuated by the at least one friction brake is increased, at least at times, with a predefined maximum brake force buildup gradient and/or up to a predefined maximum brake force. At least when no emergency braking situation is present, it is ascertained prior to the automatic braking whether the vehicle at that moment is traveling through a specified or self-determined particulate matter protection area, and, if necessary, the brake force that is effectuated with the aid of the at least one friction brake is increased at most with a predefined or set limiting brake force buildup gradient and/or at most up to a predefined or set limiting brake force.

Automatic braking device for a vehicle and method for automatically braking a vehicle

The disclosure relates to a method for driver assistance, wherein a vehicle automatically performs a driving maneuver. In the method, a service brake of the vehicle is first actuated. Then a parking brake of the vehicle is controlled in such a way that the parking brake exerts no braking influence and that the free travel to be overcome for actuation of the parking brake is minimized. In subsequent steps, the service brake of the vehicle is released and an automatic driving maneuver is performed, wherein, if a fault or a specified event occurs, the parking brake is actuated such that the vehicle is braked to a standstill and is kept at a standstill. The disclosure further relates to a driver assistance system that is designed to perform the method.
