Abstract: A method for warning the driver of a vehicle against cross traffic when leaving a parking space, wherein the motor vehicle has far-field sensors at least in the region of the rear-end corners for detecting possible cross traffic and lateral near-field sensors for detecting the near surroundings of the vehicle and wherein the warning is generated if at least one of the far-field sensors detects cross traffic. The method surveys the nearby lateral surroundings of the driver's vehicle while leaving the parking space, determines from the results of the near-field detection whether the far-field sensors have a free view of the cross traffic, and generates a notification to the driver if one or both far-field sensors do not have a free view of the cross traffic.

Abstract: A method and a device for locating a vehicle from a fixed reference map in which objects are assigned one or more positions in the reference map. At successive points of a vehicle trajectory, in each case a radar impulse is emitted and subsequently, angle-resolved and time-resolved measurements of the radar impulse response are performed. Object positions are identified in the environment surrounding the vehicle from the radar impulse response, the current identified object positions forming an environment map. The vehicle position is identified in the reference map by comparing the environment map to the reference map, the reference map being created from the identified positions and is continuously updated. An object classification for the identified object positions in the current environment map and/or reference map is performed and the identification of the vehicle position is performed while taking the object classification into account.
