NAVIGATION DEVICE

摘要

A navigation device (10) having a route search section (112) for searching for a route from a start point to destination that are specified, a sensor section (15) for detecting traveling conditions of the vehicle, a GPS reception section (12) for positioning a current position, a map storage section (13) having map information stored in it, output means (voice output section (19)), an acceleration determination section (111), and a rapid- acceleration/deceleration-information recording section (18). The acceleration determination section (111) determines that acceleration calculated based on an output of the sensor section (15) or the GPS reception section (12) is above a predetermined threshold, determines operation of rapid acceleration/deceleration based on map information obtained from the map storage section (13) on the basis of the current position positioned by the GPS reception section (12), records information on the rapid acceleration/deceleration on the rapid- acceleration/deceleration-information recording section (18), and, if the acceleration/deceleration operation is inappropriate, informs the fact to the output means (19).
