<p><P>PROBLEM TO BE SOLVED: To accurately guide a car 25 to an exit 13 from a parking place when the car exits outward from an inside of a parking lot 10. <P>SOLUTION: At an entrance 12, a guide device on a car side receives information about a section view 30, information about each square 31 in the a section view 30, communication site square information and exit square information together with a parking lot image 28 by a DSRC 27 from a road side machine 24. A square number indicating a position in the view 30, is granted to each square 31. The information of the square 31 determines which of a passage square (corresponding to a passage 16), an exit square (corresponding to an exit 13) and a parking place square (corresponding to a parking lot 15) has been turned from each square 31. The guide device detects a current site square "26", on the basis of the communication site square, etc., and when the car 25 exits, the guide device searches a guide route 34, depending on the possibility of tracing from the current site square "26" to an exit square "EF" through continuous passage squares to display the route on a display of a car navigation device on the car 25. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
