ROUTE GUIDANCE DEVICE, ROUTE GUIDANCE METHOD, ROUTE GUIDANCE PROGRAM, AND RECORDING MEDIUM

摘要

A movement history is recorded in a recording section (101), and in the movement history, the date and time of movement is associated with information on a history route on which a mobile body has moved up to a destination. When it is determined based on the result of detection by a detection section (102) that the electronic power source of the mobile body is activated, a date/time acquisition section (103) acquires a current date and time, and a position acquisition section (104) acquires positional information on a current waypoint. Then, a determination section (105) determines a destination and a history route up to the destination based on the current date and time, the positional information on the current waypoint, and the movement history. After that, when the positional information on the current waypoint acquired by the position acquisition section (104) is deviated from the history route, a search section (107) searches for a guidance route up to the destination. Then, a display section (108) displays the searched guidance route up to the destination.
