- S240: NO the setting of the extension road based on the link L4 is terminated.
- the intersection when it is determined that guidance is necessary, it includes a case where the intersection has dedicated guidance data because it is a difficult intersection even on a road. For example, as shown in FIG. 5 (b), even if the link L11 is connected to the link L8 along the road, there are many links connected to the end point T8 (L11 to L16), and the determination of the road or road is lost. This corresponds to the case where dedicated guidance data is prepared at the end point T8 when there is a possibility of possibility.
- an area along the actually traveled link (link indicated by a solid line) is defined as area A
- an area along the extended road link (link illustrated by a broken line) is defined as area B.

- the area A1 and the area B are less likely to be recognized by the store than the area A. However, it is an area where promotion to the area A (expansion of the user's action range) can be expected in the future because it has a land intuition and is easy to access compared to the area C. For this reason, it is conceivable to provide information with an emphasis on highly reusable information. For example, information such as a store that matches a user's preference that is likely to become a new favorite store and a popular menu for each store is searched and provided.

That is, on the assumption that the proper noun part is included in the name of the road, the continuity determination unit 10b may determine that there is continuity when the proper noun part matches. By determining the matching of the proper noun parts, it is possible to flexibly determine the matching of the road names.
- road names are composed in the format of [Prefix] + [Body] + [Street Type] + [Suffix].
- the proper noun part corresponds to [Body]. Therefore, when the [Body] part is matched, it may be determined that the road names are matched.
- W MAIN ROAD is composed of [Prefix] + [Body] + [Street Type].
- 5TH5AVE SE is configured by [Body] + [Street Type] + [Suffix].
- CA-10 is composed only of [Body].
- the character string match determination may be based on notation fluctuation. That is, the continuity determination unit 10b may consider the shaking of the notation in determining whether the road names match. For example, “1st” and “First” are handled as the same character string. For example, “W” and “West” are treated as the same character string, and “ST” and “street” are treated as the same character string. In this way, it is possible to more flexibly determine matching of road names.
- the continuity determination unit 10b may determine the presence or absence of continuity according to the size of the reference road connected at the reference end point and the size of the determination target road. For example, in FIG. 5B, even if the link L8 is connected to the link L5 along the road, if the roads indicated by the links L9 and L10 are higher-grade roads than the link L5, the link L8 is changed. It is possible not to set it as an extension road. It can be considered to determine whether or not the vehicle is rated based on at least one of the road type, the road width, and the number of lanes. In this way, the determination of continuity becomes more appropriate.
- the extension road may be distinguished by providing a coefficient correlated with the distance from the actually traveled link.
- the extension road setting unit 10c may set the extension roads separately by using a coefficient correlated with the distance from the moving road.
- the movement history information of the extension road is stored in the order of increasing as “3”, “4”, and “5” in the order of increasing distance from the actually traveled link. In this way, the guidance amount can be changed even on the same extension road.
- the amount of guidance may be continuously changed even on extension roads of the same link by multiplying the coefficient correlated with the above-described distance.
- the control device 10 updates the movement history information (S150) and stores the updated link even when there is a movement history (S120: YES). It may be (S160).
- the update of the movement history information means an update of the travel count of the actually traveled link.
- the moving road specifying unit 10a specifies the moving road and specifies the number of times of traveling on the moving road
- the extension road setting unit 10c may determine the number of times of setting the extension road based on the number of times of driving. . For example, in FIGS.
- extension road setting unit 10c may set the extension roads by dividing them according to a coefficient correlated with the number of travels.
- the moving road specifying unit 10a specifies the moving road and specifies whether or not the moving road is included in the searched route.
- the extension road setting unit 10c determines whether or not the moving road is included in the searched route. The number of times of extension road setting may be determined based on this. At this time, as in the case of (v), for example, in FIGS. 4 and 7, it is conceivable that the upper limit number of extension road settings (S250, S450) is set depending on whether or not it is included in the searched route. Further, for example, in FIG. 7, it may be considered to determine the maximum number N of connections in consideration of whether or not the route is included in the searched route (S310). Further, the extension road setting unit 10c may classify and set the extension road based on whether or not it is included in the searched route. In this way, the guidance amount can be changed even on the same extension road.
- the road name is used for determination of continuity (S240 in FIG. 4 and S410 in FIG. 7).
- the fact that the road scale is approximately the same may be used for determination of continuity.
- whether or not the direction is the same as the moving road, that is, whether or not a right / left turn process is required may be used for the determination of continuity.
- the switching unit 100c may determine the map display switching timing in accordance with the connection state of the road from the current location to the display target recognition road. Even if it does in this way, the same effect as the above-mentioned embodiment is produced.
- the map display is automatically switched (S540: YES, S550), and the switching instruction from the user is determined when switching to a wider map display (S560). ).
- the switching instruction indication from a user as a trigger.

For example, since there is a high possibility of returning to home at night, the direction of the home indicated by symbol H is presented, and since there is a high possibility of going to the company early in the morning or during the daytime, the direction of the company indicated by symbol C Is presented. That is, when there are a plurality of directions in which a moving road exists, the presenting unit 100e may selectively present a direction based on the date / time information. For example, as shown in FIG.
- the first direction which is the direction to the position (left side) where the first part of the moving road (the left part of the moving road with respect to the current location) exists and the second part of the moving road
- the second direction which is the direction to the position (right side) where the portion (the right portion of the moving road with respect to the current location) exists
- the second direction which is the direction to the position (right side) where the portion (the right portion of the moving road with respect to the current location) exists
- an address or city name may be displayed in addition to or instead of displaying an icon or the like.
