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.

Abstract: A parking area detection system and method is disclosed which uses mesh space analysis to virtually divide a space to be detected in a mesh shape having a lattice structure and sequentially excludes a lattice region in which an obstacle is not recognized based on a recognition signal by the ultrasonic sensor. Thus the parking area detection system is able to prevent information distortion from occurring in a space recognition process.
