Abstract

Disclosed herein are a vehicle-to-vehicle (V2V) communication-based vehicle identification apparatus and an identification method thereof. The V2V communication-based vehicle identification apparatus includes a radar sensor unit sensing radar information corresponding to relative distances to object vehicles, a GPS module unit generating GPS information from GPS satellites, a V2V communication unit transmitting the generated GPS information to the object vehicles and receiving GPS information of the object vehicles from the object vehicles through vehicle to vehicle (V2V) communication, and a controller calculating probabilities that the GPS information of the object vehicles will be located at areas, set based on the sensed radar information, and identifying vehicles corresponding to the radar information and the GPS information of the object vehicles based on the calculated probabilities.
