Navigation device and navigation program product
First Claim
1. A navigation device comprising:
- a controller including a processor configured toacquire a current location of a vehicle and specifying a travel road actually traveled by the vehicle based on input information from a geomagnetism sensor, a gyroscope, a distance sensor, and a GPS receiver;
determine an existence of a continuity between the travel road and a first road connected to an end point of the travel road, wherein the end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road;
designate the first road as a first extension road when the continuity is determined to exist between the first road and the travel road;
store, in a travel history, for each time the vehicle travels, a first indication that the travel road is actually traveled by the vehicle, and second indication that the first extension road is determined to have the continuity with the travel road; and
control a map display to be changed to contain a part of a recognition road, wherein the recognition road includes the travel road that is actually traveled and the first extension road determined to have the continuity with the travel road, when the vehicle or a destination of the vehicle are in a range around the recognition road.

Abstract
A navigation device includes a travel road specification portion acquiring a current location of a vehicle and specifying a travel road actually traveled by the vehicle, a continuity determination portion determining an existence of a continuity between the travel road and a first road connected to an end point of the travel road, and an extension road designation portion. The end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road. The extension road designation portion designates the first road as a first extension road when the continuity determination portion determines that the continuity exists between the first road and the travel road.

18. A navigation device comprising:
-
a controller including a processor configured to acquire a current location of a vehicle and specifying a travel road actually traveled by the vehicle based on input information from a geomagnetism sensor, a gyroscope, a distance sensor, and a GPS receiver; determine an existence of a continuity between the travel road and a first road connected to an end point of the travel road, wherein the end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road; designate the first road as a first extension road when the continuity is determined to exist between the first road and the travel road; and control a map display to be changed to contain a part of a recognition road, wherein the recognition road includes the travel road that is actually traveled and the first extension road determined to have the continuity with the travel road, when the vehicle or a destination of the vehicle are in a range around the recognition road, wherein, when the current location of the vehicle corresponds to one link of a double linked road, the processor is further configured to specify both the one link and an other link of the double linked road as the travel road.

19. A navigation device comprising:
-
a controller including a processor configured to acquire a current location of a vehicle and specifying a travel road actually traveled by the vehicle based on input information from a geomagnetism sensor, a gyroscope, a distance sensor, and a GPS receiver; determine an existence of a continuity between the travel road and a first road connected to an end point of the travel road, wherein the end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road; designate the first road as a first extension road when the continuity is determined to exist between the first road and the travel road; and control a map display to be changed to contain a part of a recognition road, wherein the recognition road includes the travel road that is actually traveled and the first extension road determined to have the continuity with the travel road, when the vehicle or a destination of the vehicle are in a range around the recognition road, wherein the processor is further configured to designate a plurality of extension roads including the first extension road and the second extension road based on a predetermined connection count and a continuity determination performed by the processor, and wherein the processor is further configured to set the predetermined connection count according to a scale of the travel road.

20. A navigation device comprising:
-
a controller including a processor configured to acquire a current location of a vehicle and specifying a travel road actually traveled by the vehicle based on input information from a geomagnetism sensor, a gyroscope, a distance sensor, and a GPS receiver; determine an existence of a continuity between the travel road and a first road connected to an end point of the travel road, wherein the end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road; designate the first road as a first extension road when the continuity is determined to exist between the first road and the travel road; and control a map display to be changed to contain a part of a recognition road, wherein the recognition road includes the travel road that is actually traveled and the first extension road determined to have the continuity with the travel road, when the vehicle or a destination of the vehicle are in a range around the recognition road, wherein the processor is further configured to specify the travel road and determine whether a retrieved guidance route includes the travel road, and wherein the processor is further configured to determine the number of extension roads to be established in consideration of whether the retrieved guidance route includes the travel road. - View Dependent Claims (21)
