Traffic environment recognition method and system for carrying out the same
First Claim
1. A traffic environment recognition method comprising the steps of:
- recognizing information about a plurality of recognition objects representing an environment of a host vehicle to obtain recognition results;
examining the recognition results;
merging the recognition results on the basis of results of examination of the recognition results to obtain merged information; and
producing output information by adding identification information to the merged information that at least one of the plurality of recognition objects is or is not the same as the merged information.

Abstract
A traffic environment recognition system includes an image-processing unit, an information-merging unit, a radar unit, and a network connected to the image-processing unit, the radar unit, the information-merging unit and a vehicle control unit capable of controlling the traveling operation of a host vehicle. The image-processing unit recognizes headway distance, the azimuth, relative speed and width of the preceding vehicle, and the position of the host vehicle in a lane. The radar unit recognizes headway distance, the azimuth and relative speed of the preceding vehicle. The information-merging unit receives recognition results provided by the image-processing unit and the radar unit through the network, merges the recognition results, identifies recognition objects relating to the recognition results. When a vehicle relating to the recognition results provided by the image-processing unit and a vehicle relating to the recognition results provided by the radar unit are one and the same vehicle, the information-merging unit produces output information by adding a sensor information indicating that the vehicles are one and the same vehicle to the recognition results, and sends the output information through the network to the vehicle control unit.
