NAVIGATION DEVICE

摘要

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