First Claim
1. A map display apparatus for having a map displayed on a screen together with a current vehicle position, the apparatus comprising:
- a situation determination unit for determining a travel situation of a vehicle; and
a map orientation unit for setting a specific orientation of the map that is to be displayed on the screen on a condition that the travel situation of the vehicle is determined to be corresponding to a specific situation by the situation determination unit, whereinthe situation determination unit is capable of determining whether or not the vehicle is traveling in a registered area that has a predetermined map orientation, andthe map orientation unit sets the orientation of the map to be aligned with the predetermined map orientation of the registered area when the vehicle is determined to be traveling in the registered area by the situation determination unit.

Abstract
A map in a navigation apparatus is displayed on a screen with its orientation aligned with an orientation of a facility map that is distributed in a facility when a vehicle having the navigation apparatus is traveling in a facility area that has pre-memorized guide information. When the vehicle is traveling in a meandering section of a road, a rough direction is oriented upward in the map that is displayed on the screen. Furthermore, the map is displayed with an entrance direction, which is determined as a direction at a time of entering an area outside of the road such as a parking or the like, oriented upward under a circumstance that the vehicle is constantly turning its direction.

4. A map display apparatus for having a map displayed on a screen together with a current vehicle position, the apparatus comprising:
-
a situation determination unit for determining a travel situation of a vehicle; and a map orientation unit for setting a specific orientation of the map that is to be displayed on the screen on a condition that the travel situation of the vehicle is determined to be corresponding to a specific situation by the situation determination unit, wherein the situation determination unit is capable of determining whether or not the current vehicle position is map-matched to a road on the map displayed on the screen, and the map orientation unit sets an upward orientation of the map on the screen to be aligned with one of historical travel directions of the vehicle in a travel history of the vehicle when the vehicle is determined by the situation determination unit to be in a situation that does not have the current vehicle position map-matched to the road. - View Dependent Claims (5)
