Further, the processing of each component may be realized by one program or a plurality of programs.

Next, the present location detection unit 101 and the route guidance unit 102 will be described.
The current position detection unit 101 is triggered by a user instruction or other event as a trigger, information input from the GPS unit 14, information input from the relative azimuth detection unit 15, information included in the map data 131, and vehicle state detection. The current position of the vehicle is detected based on the information input from the unit 18. Any method may be used to detect the current position of the vehicle, and information other than the information exemplified in this embodiment may be used.

The route guidance unit 102 guides a predetermined route by a user's instruction or other event as a trigger. For example, when guiding a destination route (a route from the current location of the vehicle detected by the current location detection unit 101 to a destination designated by the user), the route guidance unit 102 is based on the route information included in the map data 131. Then, a destination route, which is a route from the current position of the vehicle detected by the current position detection unit 101 to the destination specified by the user, is searched. The route guidance unit 102 displays the map on the display device 111 in a predetermined manner, displays a mark indicating the current location of the vehicle detected by the current location detection unit 101 on the map, and indicates the searched destination route. Display the image on the map and guide the destination route. Any method may be used to search for the destination route and other routes, and information other than the information exemplified in this embodiment may be used.

By the way, when a user travels to a destination by vehicle, he or she may want to go through a facility corresponding to a predetermined attribute located around the destination route. Note that "facility located around the destination route" means not only facilities located along the road corresponding to the destination route, but also within a predetermined distance from the destination route (for example, from the location of the facility to the destination). Includes facilities located within the predetermined length of the vertical line drawn to the route. For example, the user wants to charge the in-vehicle battery via a charging station corresponding to the attribute: charging station, or wants to have a light meal via a fast food restaurant corresponding to the attribute: fast food restaurant. In this case, there are cases where it is desired to carry out shopping via a convenience store that corresponds to the attribute: convenience store. Then, the navigation device 1 according to the present embodiment performs the following processing so that the user can easily search for a facility that the user desires to go through.
Hereinafter, the process of the navigation device 1 regarding the facility search will be described in detail.

FIG. 2 is a flowchart showing the operation of the navigation device 1.
In the following description with reference to FIG. 2, the user has designated the destination by a predetermined means at the start of the flowchart, and the route guidance unit 102 has searched for the destination route. And

As shown in FIG. 2, when searching for a facility having a predetermined attribute located around the destination route, the user performs a predetermined operation on the touch panel 11 or the operation switch 121 to display the attribute selection screen G31. Is instructed (step S1). Hereinafter, a facility having a predetermined attribute located around the destination route is referred to as a “search target facility”, and an attribute corresponding to the search target facility is referred to as a “search target attribute”.

When the user's instruction in step S1 is detected, the facility attribute setting unit 103 displays the attribute selection screen G31 on the display device 111 (step SA1).

FIG. 3 is a diagram showing the attribute selection screen G31.
The attribute selection screen G31 is a screen for selecting a search target attribute. As shown in FIG. 2, the attribute selection screen G31 has an attribute selection field N31. Information indicating selectable attributes is displayed in a list in the attribute selection field N31. The attribute selection screen G31 also has a confirm button B31 for confirming the attribute selection.

The user confirms the selection by selecting the information corresponding to the search target attribute from the information indicating the attribute displayed in the attribute selection field N21 and operating the confirm button B31 (step S2).

After displaying the attribute selection screen G31, the facility attribute setting unit 103 monitors whether or not the confirm button B31 has been operated (step SA2).
When detecting that the confirm button B31 has been operated (step SA2: YES), the facility attribute setting unit 103 displays the information indicating the attribute selected by the user among the information indicating the attributes displayed in the attribute selection field N31. The attribute indicated by the acquired information is set as the search target attribute (step SA3). That is, the facility attribute setting unit 103 sets the facility attribute based on the user's operation.

Next, the facility display unit 104 searches for a facility (search target facility) corresponding to the search target attribute set by the facility attribute setting unit 103 based on the facility information included in the map data 131 (step SA4). Any method may be used as a method for searching the facility to be searched, and information other than the information exemplified in this embodiment may be used. As a result of the processing in step SA4, the facility display unit 104 indicates that the facility is located around the destination route (for example, the facility located within a radius of 1 km from the destination route) and corresponds to the attribute designated by the user. Is searched for. It should be noted that the facility display unit 104 may search only the facilities located facing the destination route.

Next, the facility display unit 104 detects an event point on the destination route where a predetermined event occurs (step SA5). The event point will be described later in detail together with the predetermined event.

Next, the facility display unit 104 displays the search result screen G41 on the display device 111 (step SA6).

FIG. 4 is a diagram showing the search result screen G41.
As shown in FIG. 4, the search result screen G41 is divided into a region A41 and a region A42. A list screen G411 (list) is displayed in the area A41. A map screen G412 (map) is displayed in the area A42.
The list screen G411 will be described below, and then the map screen G412 will be described.

First, the list screen G411 will be described.
The facility display unit 104 arranges, on the list screen G411, information indicating the search target facility searched in the process of step SA4 and information indicating the event point searched in the process of step SA5 in a predetermined order, and a list. indicate. In the following description, when the search target facility and the event point are not distinguished, it is referred to as “corresponding point”, and when the information indicating the search target facility and the information indicating the event point are not distinguished, “corresponding point information” ".

To be more specific, the facility display unit 104 displays each of the corresponding point information on the list screen G411 in order from the top to the bottom in the order in which the traveling distance when the vehicle travels from the current position to the corresponding point is short. .. Hereinafter, the travel distance when the vehicle travels from the current position to the corresponding point is simply referred to as “travel distance”.

Further, the facility display unit 104 displays one corresponding point information (information indicating one search target facility or information indicating one event point) on the list screen G411 in the horizontally long rectangular item image KG. To do. Each of the item images KG can be selected by a touch operation. In the item image KG, as corresponding point information, corresponding point name information J41 indicating the name of the corresponding point, icon information J42 indicating the icon of the corresponding point, and traveling distance information J43 indicating the traveling distance to the corresponding point are displayed. To be done.

In this way, on the list screen G411, the information indicating the search target facility and the information indicating the event point are displayed side by side in the ascending order of the travel distance. Therefore, the list screen G411 displays the information indicating the search target facility above the information indicating the one event point for the search target facility whose traveling distance is shorter than the one event point, and the one event For the search target facility having a longer travel distance than the point, the information indicating the search target facility is displayed below the information indicating the one event point. Therefore, by referring to the list screen G411, the user can intuitively and easily understand whether or not the traveling distance is shorter than the predetermined event point for each of the search target facilities. Specifically, the user only needs to know whether the information indicating the search target facility is displayed above or below the information indicating the predetermined event point as a boundary. Can grasp whether or not the travel distance of the facility to be searched is short.

Hereinafter, the event points will be specifically described, and the effect of displaying the information on the list screen G411 in the above-described manner will be described for each of the event points.

<First example of event location>
A first example of an event point is a point corresponding to a partition between a general road and a highway when the road corresponding to the destination route includes the general road and the highway (for example, in various gates on the highway. Corresponding point).

When the event point includes the event point according to the first example, the list screen G411 indicates that the information indicating the point corresponding to the division between the general road and the highway and the information indicating the search target facility are the traveled distances. Are displayed in short order. This brings about the following effects.

In other words, when the vehicle travels on the highway corresponding to the destination route, the user cannot deviate from the highway corresponding to the destination route to drive the vehicle, and the vehicle basically moves on the highway. You will be traveling along. On the other hand, when the vehicle travels on the general road corresponding to the destination route, the user can drive the vehicle while deviating from the general road corresponding to the destination route. Further, when the vehicle travels on the highway along the destination route, the facilities that can be passed through are limited to the facilities provided along the highway such as the service area and the parking area. On the other hand, when the vehicle travels on the general road corresponding to the destination route, the facilities that can be passed through are not limited to the facilities provided along the general road corresponding to the destination route. As described above, the traveling mode of the vehicle and the transitable facility are different between the case of traveling on the general road and the case of traveling on the highway.

Based on the above, depending on the attribute, there are cases where it is desirable for the vehicle to go through while traveling on a general road and where there are cases where it is desirable for the vehicle to go through while traveling on a highway. To do.
For example, for a charging station that corresponds to the attribute: charging station, it is desirable that charging be performed while the vehicle is traveling on a general road. In some cases, it may be desirable to charge the vehicle via a charging station that has the shortest mileage between the charging station and the charging station. This is because it is possible to drive the highway efficiently without charging the on-vehicle battery at the charging stand as much as possible, and it is possible to shorten the time required to reach the destination.

Then, on the list screen G411, the information indicating the point corresponding to the division between the general road and the expressway and the information indicating the search target facility are displayed side by side in ascending order of mileage. The following can be recognized by referring to the screen G411. That is, the user can recognize whether or not each of the search target facilities can pass through while traveling on the general road before entering the highway, and also the positional relationship between the point entering the highway and the search target facility. Can be recognized intuitively and easily. Based on the recognition, the user can easily select an appropriate facility as a transit facility among the search target facilities by reflecting that the road corresponding to the destination route includes a highway.

FIG. 4 shows the list screen G411 when the search target attribute is attribute: charging station and the event point includes the event point according to the first example. By referring to the list screen G411 shown in FIG. 4, the user travels in the order of AAA charging station→BBB charging station→CCC charging station→XXX highway entrance→DDD charging station, AAA charging station and BBB charging. It is possible to intuitively and easily recognize that the stand and the CCC charging stand are the charging stands that can be passed through while traveling on the general road before entering the highway. In addition, the user can intuitively easily understand that the CCC charging station is the charging station that has the shortest traveling distance between the XXX highway entrance and the charging station among the charging stations that can be passed through while traveling on a general road. Can be recognized by. Based on these recognitions, the user can easily select the CCC charging station as the facility to pass through.

<Second example of event location>
A second example of an event point is a reachable point. The reachable point is a point where the vehicle can travel normally without traveling to the road corresponding to the destination route without charging the in-vehicle battery, and can be reached normally. That is. The facility display unit 104 detects a reachable point based on the information indicating the cruising distance detected based on the input from the battery remaining amount detection unit 19, the information included in the map data 131, and other information. Any method may be used to detect the reachable point, and information other than the information exemplified in this embodiment may be used.

When the event point includes the event point according to the second example, the list screen G411 displays the information indicating the reachable point and the information indicating the search target facility side by side in the order of shorter travel distance. .. This brings about the following effects.

That is, the electric vehicle has a characteristic that the cruising distance is shorter than that of the gasoline vehicle. The cruising range refers to a distance that an electric vehicle can travel without charging a vehicle battery, and a gasoline vehicle can travel without refueling. In addition, in the situation where the charging station is not widely used, even if the charging station is searched for the first time when the remaining amount of the vehicle battery is low, there is no charging station that can be reached without running out of the vehicle battery level. It may happen that it does not exist. Therefore, when the user drives the electric vehicle to reach the destination, it is necessary to charge the vehicle-mounted battery at an appropriate timing and at an appropriate charging stand.

Based on this, there are some facilities that may be required to pass before the reachable point or may need to pass before the reachable point depending on the attribute.
For example, for the charging station corresponding to the attribute: charging station, it is necessary to pass before the reachable point.

Then, on the list screen G411, the information indicating the reachable points and the information indicating the facilities to be searched are displayed side by side in the ascending order of mileage. Therefore, the user can refer to the list screen G411 to I can recognize that. That is, the user can recognize whether or not each of the search target facilities can be reached before the reachable point, and can intuitively and easily recognize the positional relationship between the reachable point and the search target facility. Based on the recognition, the user can easily select an appropriate facility as a routed facility among the search target facilities based on the position of the reachable point.

<Third example of event location>
A third example of the event point is a traffic jam start point and a traffic jam end point. The congestion start point is a point where congestion starts on the road corresponding to the destination route. The congestion ending point is a point where the congestion ends on the road corresponding to the destination route. The facility display unit 104 detects the congestion start point and the congestion end point based on the road traffic information input from the beacon reception unit 16 or the FM multiplex reception unit 17. Any method may be used to detect the congestion start point and the congestion end point, and information other than the information exemplified in this embodiment may be used. For example, it may be configured to communicate with a server that provides information about the congestion start point and the congestion end point via a network including the Internet, and acquire the congestion start point and the congestion end point from the server.

When the event point includes the event point according to the third example, the list screen G411 indicates that the information indicating the congestion start point and the congestion end point and the information indicating the search target facility are in the order of the shortest travel distance. Are displayed side by side. This brings about the following effects.

That is, when a vehicle travels on a road that is congested, the traveling distance per unit time is shorter than when it travels on a road that is not congested. The movement of the vehicle is restricted. As described above, the traveling mode of the vehicle is different between the case where the vehicle travels on the congested road and the case where the vehicle travels on the non-congested road.

Based on the above, some facilities may be desirable to pass while traveling on a road that is not congested, depending on the attributes.
For example, for a restaurant (for example, a fast food restaurant corresponding to an attribute: fast food restaurant), it may be desirable to pass while traveling on a road that is not congested before entering a road that is congested. .. The restaurant is required to pass through at the time desired by the user, reflecting the hunger of the user. However, when the restaurant is located at a position corresponding to the congested road, it corresponds to the uncongested road. This is because there is a high possibility that it will not be possible to go through at the desired time as compared with the case of being in the position.

Then, on the list screen G411, the information indicating the congestion start point and the congestion end point, and the information indicating the search target facility are displayed side by side in the order of the shortest mileage. Therefore, the user can display the list screen G411. By referring to it, the following can be recognized. That is, the user can recognize whether or not each of the search target facilities can pass through while traveling on a road that is not congested, and intuitively determine the positional relationship between the congested section and the search target facility. Can be recognized by. Based on the recognition, the user can easily select an appropriate facility as a facility to be routed from among the search target facilities.

The event points have been described above with three examples. However, the event point is not limited to the example.

For example, the event location may include a location where an accident has occurred. Driving of the vehicle may be restricted at the point where the accident occurs. For this reason, there are some facilities where it may be desirable to pass before or after the point where the accident has occurred. By displaying the information indicating the location where the accident has occurred on the list screen G411 together with the information indicating the facility to be searched, the user intuitively finds the positional relationship between the location where the accident has occurred and the facility to be searched. After recognizing it easily, you can easily select the appropriate facility as the facility to pass through.

Further, for example, the event point may include a point where construction is being performed. According to this configuration, the same effect as in the case where the event location includes the location where the accident has occurred is achieved.

Further, for example, the event point may include a waypoint preset by the user. The list screen G411 displays the information indicating the facility to be searched and the waypoint, so that the user can intuitively and easily recognize the positional relationship between the waypoint and the facility to be searched, and then select the facility as the waypoint. Easy selection of suitable facilities.

Here, in the present embodiment, as event points, three types are prepared: a point corresponding to the division between the above-described general road and the expressway, a reachable point, a traffic jam start point, and a traffic jam end point. .. Then, in the present embodiment, when displaying the list screen G411, the facility display unit 104 does not display information indicating all types of event points, but does not display any type of event points. Can be That is, the facility display unit 104 may not include information on some of the event points (points at which a predetermined event occurs) in the list screen G411 (list).

More specifically, the navigation device 1 has a configuration in which the user can preset the type of an event point whose information is to be displayed on the list screen G411 among the three types of event points. Then, the facility display unit 104 displays, on the list screen G411, information indicating an event point of a type preset as a target for displaying information by the user, while information indicating an event point of another type is displayed on the list screen G411. Do not display in. This brings the following effects. That is, with the above configuration, it is possible to prevent information indicating unnecessary types of event points that the user does not want from being displayed on the list screen G411, and thus it is possible to improve the legibility of the list screen G411.

Note that the facility display unit 104 may be configured to automatically determine the type of event point for which information is to be displayed on the list screen G411 according to the search target attribute. In this case, regarding the type of the event spot to be displayed according to the search target attribute, is it useful for the user to select the search target facility by displaying the information indicating the event spot together with the information indicating the search target facility? It is set appropriately from the perspective of whether or not. For example, when the search target attribute is the attribute: charging station, the facility display unit 104 determines the type of reachable point as the type of event point for which information is displayed on the list screen G411.

Further, the facility display unit 104 includes the information indicating the event point in the list screen G411 in a mode different from the mode of displaying the information indicating the search target facility. The details will be described below with reference to FIG. Among the item images KG displayed on the list screen G411 of FIG. 4, the item image KG1 is the item image KG on which the information indicating the search target facility is displayed, and the item image KG2 is the item on which the information indicating the event point is displayed. This is the image KG. As is clear from a comparison between the item image KG1 and the item image KG2, the horizontal length of the item image KG2 is smaller than the horizontal length of the item image KG1. Thereby, the user who refers to the list screen G411 can easily and intuitively recognize which item image KG is the item image KG related to the search target facility and which item image KG is the item image KG related to the event point. it can. It should be noted that the method of making the display mode of the information indicating the event point different from the display mode of the information indicating the search target facility is not limited to the method exemplified in the present embodiment. For example, the color or font of the character string displayed in the item image KG may be changed, the color or shape of the item image KG may be changed, and each information displayed in the item image KG (this example Then, the order of the corresponding point name information J41, the icon information J42, and the traveling distance information J43) may be changed.

Next, the map screen G412 will be described.
The facility display unit 104 displays the map on the map screen G412 in the following manner. That is, as shown in FIG. 4, the facility display unit 104 displays a map of a predetermined scale previously designated by the user on the map screen G412. Further, the facility display unit 104 displays the vehicle position mark PM indicating the current position of the vehicle and the destination route image MG indicating the destination route on the map displayed on the map screen G412 by the route guide unit 102 described above.
