  • Patent number: 10479273
    Abstract: A method for avoiding or reducing damage to a parked vehicle caused by a collision with an approaching vehicle performing a parking operation included determining, by the parked vehicle, a risk of collision, transmitting a warning signal if the risk of collision is sufficiently high, monitoring whether the approaching vehicle reacts to the warning signal, and performing a maneuver by the parked vehicle to avoid or reduce collision damage if there is no reaction. The maneuver may permit a controlled contact between the parked vehicle and the approaching vehicle to minimize the force of the contact. After such a controlled contact, a braking torque exerted by the parked vehicle is increased. Following completion of the damage avoidance maneuver, an estimate of the extent of the completed damage prevention is made and provided to the owner of the parked vehicle (including information about potential saved repair costs).

  • Patent number: 10363960
    Abstract: A maneuvering process of a motor vehicle is assisted in at least partially automated fashion from a present position into a target position. A multiplicity of possible trajectories from the present position into the target position are determined. One of said trajectories is defined as the trajectory to be followed by the vehicle during the maneuvering process on the basis of a predefined criterion. The definition is performed repeatedly during the execution of the maneuvering process, with the trajectory to be followed being updated in each case.

  • Patent number: 10328843
    Abstract: A driving assistance system for a vehicle has a longer-distance sensor device for determining longer-distance information between a vehicle and an obstacle, and a shorter-distance sensor device for determining shorter-distance information between the vehicle and the obstacle. A dual-mode light emitting diode (LED module) can selectively emit both visible light and infrared light, and is part of the vehicle's driving-lights system, such as a headlight and/or a reversing light. The LED module emits infrared light when operating as part of the shorter-distance sensor device and an infrared receiver detects the reflected infrared light for distance determination. The longer-distance sensor device uses ultrasonic waves to determine distance information, and when it indicates that the distance has fallen below a threshold distance (below which the longer-distance sensing device is not reliable), a controller activates the shorter-distance sensing device.
