Abstract
(EN)
In this route searching method, a driver behavior history is accumulated in a database. When the behavior history has been accumulated, the area on a map of a familiar region based on map positions for which the behavior history has been accumulated is expanded compared to the area in a case where the behavior history has not been accumulated, and a second route for arriving at a destination that is different from a first route for arriving at the destination is searched for from within the familiar area.

La présente invention concerne un procédé de recherche d'itinéraire, dans le cadre duquel un historique de comportement de conducteur est accumulé dans une base de données. Lorsque l'historique de comportement a été accumulé, la zone sur une carte d'une région familière sur la base de positions de carte pour lesquelles l'historique de comportement a été accumulé est étendue par rapport à la zone au cas où l'historique de comportement n'ait pas été accumulé, et un second itinéraire pour arriver à une destination différente d'une première route pour arriver à la destination est recherchée à partir de l'intérieur de la zone familière.
(JA)
ルート探索方法は、ドライバーの行動履歴をデータベースに蓄積し、行動履歴が蓄積されている場合、行動履歴が蓄積されていない場合に比べて、行動履歴が蓄積されている地図上の位置を基準とする地図上のなじみ領域の面積を広げ、なじみ領域の中から、目的地に到達するための第1のルートとは異なる第2のルートを探索する。
