Thereby, the system controller 20 improves a user's convenience. This specific example will be described below.

(Registration of unique charging facility information Ipi)
First, the registration method of the specific charging facility information Ipi will be described with reference to FIG. FIG. 2 shows a specific example of a display screen (hereinafter referred to as “facility information registration screen”) displayed when facility information is registered. That is, the facility information registration screen shown in FIG. 2 is an example of a screen that is displayed on the navigation device 1 when the user performs a predetermined operation when the user registers the facility information.

  The facility information registration screen of FIG. 2 has setting buttons 401 to 406 that are selected when setting each setting item such as a name. Next to the setting buttons 401 to 406, setting display fields 411 to 416 indicating the contents set by the setting buttons 401 to 406 are provided. When the setting buttons 401 to 406 are selected, the system controller 20 separately displays an input screen (not shown) and accepts input from the user.

  Specifically, the setting button 401 is a button that is selected when registering a facility name of a facility to be registered (a facility to be registered). Here, the setting display field 411 indicates that the facility name of the facility to be registered is set as “XXX's house”. The setting button 402 is a button that is selected when registering the phonetic name of the facility to be registered. The setting display field 412 indicates that the phonetic is set as “No. XXX”. A setting button 403 is a button selected when setting an icon displayed on the map display screen. The setting display column 413 indicates that “♪” is set as the icon of the registration target facility. The setting button 404 is a button that is selected when setting whether or not the registration target facility is the charging facility Pe. The setting display field 414 indicates that the registration target facility is the charging facility Pe. That is, in this case, the registration target facility is the specific charging facility Pi. The setting button 405 is a button that is selected when registering information related to a charging fee when a vehicle is charged at a registration target facility. The setting display column 415 indicates that the charge charge is 300 yen and the late-night charge is 1/3 discount. The setting button 406 is a button that is selected when registering whether or not use permission to charge the vehicle is obtained at the registration target facility. The setting display field 416 indicates that there is a use permission for charging at the registration target facility.

  As described above, the system controller 20 provides the setting buttons 404 to 406 on the facility information registration screen, so that information on whether or not the registration target facility is the charging facility Pe, information on the charging fee, and use permission for charging. The user can input information on the presence or absence of Thereby, the system controller 20 enables registration of the specific charging facility Pi and can perform route guidance using the specific charging facility Pi. Thereby, the system controller 20 can improve a user's convenience.

(Route search)
Next, route search using the specific charging facility information Ipi will be described with reference to FIG. FIG. 3 is an example of a processing procedure executed by the system controller 20 in order to display a candidate route from the current location to the destination when the user designates the destination. The system controller 20 executes the process shown in FIG. 3 when a destination is designated by the user. Hereinafter, the “second candidate route R2” is a route that is a target when selecting a route candidate (hereinafter referred to as “final candidate route”) from the current location to the destination presented to the user. Thus, it refers to a route in which the vehicle can travel by using the charging facility Pe on the route or without charging. The “first candidate route R1” refers to a candidate route that can be taken from the current location to the destination, which is a target when the second candidate route R2 is selected.

  First, the system controller 20 searches for the first candidate route R1 (step S101). For example, the system controller 20 selects, as the first candidate route R1, a predetermined number of routes that are limited based on the travel distance among the possible routes from the current location to the destination based on the map data.

  Next, the system controller 20 calculates the planned travel distance of each first candidate route R1 (hereinafter, referred to as “route-specific travel planned distance Dr”) (step S102). Then, the system controller 20 calculates a travelable distance of the vehicle (hereinafter referred to as “travelable distance Dlim”) (step S103). Specifically, system controller 20 calculates travelable distance Dlim with reference to a predetermined formula or map based on the remaining capacity of the power storage device mounted on the vehicle and the fuel consumption of the vehicle. The fuel consumption described above may be stored in advance in the data storage unit 36 or the ROM 23 (hereinafter simply referred to as “memory”), and is calculated by the system controller 20 based on the past travel distance and the amount of electricity consumed. It may be.

  Next, the system controller 20 determines whether or not it is possible to travel without charging each first candidate route R1 (step S104). Specifically, the system controller 20 determines whether the travelable distance Dlim is greater than or equal to the route-specific travel planned distance Dr. Thus, the system controller 20 determines whether or not it is necessary to perform charging with the charging facility Pe as a stop when the first candidate route R1 is traveled.

  When the system controller 20 determines that the predetermined first candidate route R1 is a route that can be traveled without charging (step S104; Yes), that is, the travelable distance Dlim is greater than or equal to the planned travel distance Dr by route. When it is determined that the first candidate route R1 is designated as the second candidate route R2 (step S105). That is, the system controller 20 recognizes the first candidate route R1 as a travelable route.

  On the other hand, when the system controller 20 determines that the predetermined first candidate route R1 is a route that cannot be traveled without charging (step S104; No), that is, the travelable distance Dlim is traveled by route. If it is determined that the distance is smaller than the planned distance Dr, it is determined whether or not there is a charging facility Pe around the first candidate route R1 (step S106). Here, the “periphery” refers to a place within a predetermined distance from the target route, for example. Accordingly, in this case, for example, the system controller 20 searches for a facility within a predetermined distance from the first candidate route R1, and determines whether or not the charging facility Pe exists in the searched facility. Thereby, the system controller 20 determines whether or not the first candidate route R1 is a travelable route.

  If the system controller 20 determines that the charging facility Pe exists around the first candidate route R1 (step S106; Yes), the system controller 20 generates a second candidate route R2 with the charging facility Pe as a stoppage (step). S107). That is, in this case, the system controller 20 changes the first candidate route R1 described above to a route that passes through the charging facility Pe. Then, when it is assumed that the vehicle is charged at the charging facility Pe, the system controller 20 determines that the route can travel. Preferably, the charging facility Pe set as a stopover is limited to a traveling distance from the current location to the charging facility Pe that is equal to or less than the travelable distance Dim.

  Here, the system controller 20 includes the unique charging facility Pi in the charging facility Pe and executes the processes of step S106 and step S107. Thereby, the system controller 20 can increase the number of candidate routes that can be traveled and can improve the convenience for the user.

  Note that, when a plurality of charging facilities Pe can be set as stopovers, the system controller 20 selects and sets one charging facility Pe as a stopover based on a predetermined rule or at random. The case where there are a plurality of charging facilities Pe around the first candidate route R1 will be further described in detail in the second embodiment.

  On the other hand, when the system controller 20 determines that there is no charging facility Pe around the first candidate route R1 (step S106; No), the process proceeds to step S108. That is, in this case, the system controller 20 determines that the first candidate route R1 is not a travelable route.

  Then, the system controller 20 determines whether or not the process of step S104 has been executed for all the first candidate routes R1 (step S108). When the system controller 20 determines that the process of step S104 has been executed for all the first candidate routes R1 (step S108: Yes), the process proceeds to step S109. On the other hand, when the system controller 20 determines that there is a first candidate route R1 for which step S104 has not been executed (step S108; No), the system controller 20 executes the process of step S104 for the first candidate route R1.

  Next, the processing after step S109 will be described. The system controller 20 displays a route selection screen based on the second candidate route R2, and changes the display screen based on a user operation (step S109). Specifically, the system controller 20 selects the final candidate route from various viewpoints such as the distance, road width, and presence / absence of a toll road from the second candidate route R2, and displays a route selection screen. Further, the system controller 20 changes the display screen as appropriate based on the input from the input device 60. A specific example of the display screen displayed in step S109 will be described in detail later (screen display example). As a result, the system controller 20 causes the user to select a route for route guidance.

  Next, the system controller 20 determines whether or not a route that uses the specific charging facility Pi as a stopover has been selected (step S110). In other words, the system controller 20 sets a route (hereinafter also referred to as “route guidance route Rd”) as a route guidance target selected as a route traveled by the user in step S107 as the specific charging facility Pi as a stop. It is determined whether or not If the system controller 20 determines that the route having the specific charging facility Pi as the stoppage has been selected as the route guidance route Rd (step S110; Yes), the system controller 20 determines whether or not the specific charging facility Pi has permission to charge. (Step S111). For example, the system controller 20 determines whether or not charging permission is set by the setting button 406 as the registration information of the specific charging facility Pi. If the system controller 20 determines that there is a charge permission for the specific charging facility Pi (step S111; Yes), the process of the flowchart ends. On the other hand, if the system controller 20 determines that there is no charging permission for the specific charging facility Pi (step S111; No), the system controller 20 displays the contact information of the specific charging facility Pi for obtaining the charging permission, and makes a prior contact. (Step S112). Here, the contact information corresponds to, for example, a telephone number or an e-mail address. Thereby, the system controller 20 can make the user use the charging facility Pe smoothly.

  On the other hand, when the system controller 20 determines that the route having the specific charging facility Pi as the stoppage is not selected as the route guidance route Rd (step S110; No), the process of the flowchart ends.

(Example of screen display)
Next, an example of a screen display that the system controller 20 displays on the display unit 40 in step S109 described above will be described with reference to FIGS.

  FIG. 4A is an example of a screen for confirming and selecting a candidate route displayed when the user sets a destination (hereinafter referred to as “route selection screen”). As shown in FIG. 4A, the route selection screen displays the candidate routes “R421” to “R425” in the map display area 420 on the left side, and each candidate on the selection screen on the right side of the map display area 420.

The icon “Ig” is an icon that displays the location of the destination, and the icon “In” is an icon that displays the location of the current location.

  Here, the buttons 421 to 426 will be supplementarily described. The button 421 displayed as “distance priority” is a button for selecting, as the route guidance route Rd, the candidate route R421 having the shortest route-specific travel distance Dr out of the second candidate routes R2. In addition, the button 422 displayed as “toll road priority” is a button for selecting, as the route guidance route Rd, the candidate route R422 having the longest toll road distance or distance among the second candidate routes R2. The button 423 displayed as “general road priority” is a button for selecting, as the route guidance route Rd, the candidate route R423 having a long general road ratio or distance from the second candidate route R2.
