Patent ID: 8077077

Claim:
A recognition system comprising: a recognition device provided in a subject vehicle and including a radar ECU configured to determine a position of an object by radiating a radar wave and receiving a reflected wave reflected by the object; and a transmission device provided in the subject vehicle, the transmission device configured to wirelessly transmit present position information of the subject vehicle into a surrounding area, wherein the recognition device includes a system ECU configured to: receive position information; acquire the present position information of the recognition device; recognize as a nearby object an object presumed to be equipped with a communication device among objects whose positions have been determined by the radar ECU based on a result of analysis by the radar ECU, the position information received by the system ECU, and a result of acquisition by the system ECU; and correct the position information of the nearby object based on the result of acquisition by the system ECU and the position information of the nearby object received by the system ECU; wherein the recognition device is configured to check whether a plurality of nearby objects recognized by the system ECU are a single object; the transmission device is provided in each of a plurality of vehicles and configured to transmit ID information and size information, the ID information being specific to each vehicle and the size information being indicative of a size of each vehicle; the system ECU is configured to receive the ID information and the size information of vehicles other than the subject vehicle; and the system ECU is configured to perform a check operation on nearby objects of vehicles, which are indentified by the ID information received by the system ECU, based on the corrected position of each nearby object corrected by the system ECU and the size information of each nearby object received by the system ECU.
