SYSTEM AND METHOD FOR DETECTING A VEHICLE IN THE VICINITY BY USING WIRELESS COMMUNICATION
First Claim
1. A system for detecting whether one more vehicles are in the vicinity of a first vehicle using wireless communication, the system comprising:
- a plurality of wireless signal transmitting units configured to generate a wireless signal;
a plurality of wireless signal receiving units configured to receive the wireless signal generated within a nearby vehicle;
a nearby vehicle distance calculation unit configured to calculate a distance to the nearby vehicle according to a strength of a received wireless signal from the nearby vehicle;
a nearby vehicle location estimation unit configured to estimate a location of the nearby vehicle by using a distance between the plurality of the wireless signal receiving units and the calculated distance to the nearby vehicle;
a nearby vehicle driving speed estimation unit configured to estimate a driving speed of the nearby vehicle based on a travel distance per a unit of time of the nearby vehicle by using the location of the nearby vehicle; and
a nearby vehicle driving direction estimation unit configured to estimate a driving direction of the nearby vehicle by using the location of the nearby vehicle.

Abstract
The present invention provides a system and a method for detecting whether one more vehicles are in the vicinity of a first vehicle using wireless communication. More specifically, a plurality of transmitters generate a wireless signal and plurality of receivers receive the wireless signal generated in a nearby vehicle. A first unit calculates a distance to the nearby vehicle according to a strength of the received wireless signal. A second estimation unit estimates a location of the nearby vehicle by using a distance between the plurality of the wireless signal receiving units and the calculated distance to the nearby vehicle. A third unit estimates a driving speed of the nearby vehicle based on a travel distance per a unit time of the nearby vehicle by using the location of the nearby vehicle. Subsequently, a fourth unit estimates a driving direction of the nearby vehicle by using the location of the nearby vehicle.
