摘要 |
<p>A route search location determining section (12d) of a mobile body (10) decides whether to conduct a route search at the mobile body (10) or to request the route search to an information center(30) based on various conditions such as priorities and how old the map data version is. In this manner, effective search can be conducted using two distinct route searching devices. Also, a current position calculating section (12a) can execute map matching by adding route data obtained from the information center (30) as a map matching candidate. <IMAGE></p> |
