Method and apparatus for analysis of a vehicle environment, and vehicle equipped with such a device
First Claim
1. A method to analyze a vehicle environment, comprising:
- arranging a first sensor group, having at least two radar sensors, on a vehicle such that emitted and received radar waves interfere;
emitting radar waves to a vehicle environment via the radar sensors;
receiving reflected radar waves via the radar sensors to generate interference data indicative of the vehicle environment;
detecting an object via the reflected radar waves and via one or more camera sensors;
outputting radar information, determined by the interference data, about the vehicle environment from received radar waves;
outputting a longitudinal position of the object relative to the vehicle based on the reflected radar waves; and
outputting a transverse position of the object relative to the vehicle based on data from the one or more camera sensors.

Abstract
A method to analyze of a vehicle'"'"'s surroundings is specified. The method includes: arranging a first sensor group with at least two radar sensors on a vehicle, emitting radar waves using the radar sensors into the vehicle environment, reflecting the emitted radar waves at objects in the vehicle'"'"'s environment, receiving the reflected radar waves using the radar sensors, identifying information about the vehicle'"'"'s environment from the received radar waves and outputting the radar information. In order to improve the analysis of the carriageway environment, the radar sensors are arranged on the vehicle such that the emitted and received radar waves interfere. Radar information is obtained by taking account of the resulting interference data. In addition, a vehicle apparatus to analyze a vehicle'"'"'s surroundings.
