  • Patent number: 8712642
    Abstract: An obscured state of a vehicle, in which a distance measuring sensor of an assistance system is obscured by a part of the vehicle, is automatically detected. If the obscured state is present, a steering intervention of the assistance system into a steering system of the vehicle during a parking or parking-bay-exiting process of the vehicle using the assistance system is automatically deactivated or prevented. Furthermore, to avoid a collision of the vehicle using the assistance system, a notification of an obscured state is automatically generated when the obscured state is present.
