초록 ▼

A vehicle navigation system enables a recognized vehicle position to be corrected to be a position on the correct road even if the vehicle position has been erroneously determined to be on a wrong road, after passing a branching point. A first map matching processing section obtains a most probable candidate road and other candidate roads by map matching processing after passing a branching point, and corrects the vehicle position to a position on the most probable candidate road, the corrected position being regarded as representing the actual vehicle position. A second map matching section corrects the dead-reckoned vehicle position to be a position on another candidate road, and sets the corrected position as a temporary vehicle position. Thereafter, the map matching processing sections perform first map matching processing based on the actual vehicle position and second map matching based on the temporary vehicle position each time a predetermined distance is traveled, in parallel with each other. When the first map matching processing finds no road on which map matching is to be performed, the first map matching is continued by setting the temporary vehicle position as the actual vehicle position.

대표청구항 ▼

[ What is claimed is:] [1.] A vehicle navigation method in which a position of a vehicle is dead-reckoned when a predetermined distance is traveled by the vehicle, a most probable candidate road satisfying a predetermined condition is obtained from the dead-reckoned vehicle position and by map matching processing, the vehicle position is corrected to a position on a most probable candidate road, and the map matching processing is thereafter continued by dead-reckoning the vehicle position, said method comprising:monitoring whether a point from which two or more branch roads extend has been passed;obtaining a most probable candidate road and a candidate road different from the most probable candidate road and satisfying said predetermined condition by map matching processing after passing the point;correcting the dead-reckoned vehicle position to a position on the most probable candidate road to regard the corrected position as an actual vehicle position;correcting the dead-reckoned vehicle position to be a position on the other candidate road, to set the corrected position as a temporary vehicle position;thereafter executing map matching processing based on the actual vehicle position and map matching processing based on the temporary vehicle position when the predetermined distance is traveled; andcontinuing map matching processing by setting the temporary vehicle position as the actual vehicle position when the map matching processing based on the actual vehicle position finds no road satisfying said predetermined condition.
