  [Description of Operation] Next, the operation of the replenishment facility display process performed by the navigation device 100 will be described. FIG. 6 is a flowchart showing the supply facility display process performed by the navigation device 100. This flow is performed every predetermined period (for example, 10 minutes) after the navigation apparatus 100 is activated.

  First, the movable distance specifying unit 104 acquires information on the remaining amount of the power source (step S001). Specifically, the movable distance specifying unit 104 acquires information on the remaining amount of the battery from the battery management module attached to the battery as a percentage, and uses it as remaining amount information.

  Next, the movable distance specifying unit 104 specifies the output efficiency of the power source (step S002). Specifically, the movable distance specifying unit 104 calculates an average power consumption.

  Then, the movable distance specifying unit 104 specifies the movable distance (step S003). Specifically, the movable distance specifying unit 104 specifies the movable distance according to the remaining battery level using the average power consumption.

  And the range specific | specification part 105 specifies the shape of the range according to the movable distance (step S004). Specifically, the range specifying unit 105 reads and specifies the shape 402 corresponding to the remaining amount level to which the movable distance specified in step S003 belongs, from the display shape table 400.

  Then, the replenishment facility specifying unit 106 lists replenishment facilities inside the range shape (step S005). Specifically, the supply facility specifying unit 106 replaces the shape of the range specified in step S004 with a geographical range, and sets the facility name 301 of the supply facility whose position 302 is included in the range in the facility information table 300. Read from and list.

  Then, the excluded facility specifying unit 107 specifies an unreachable facility among the listed supply facilities as an excluded facility (step S006). Specifically, the excluded facility specifying unit 107 requests the basic control unit 101 to search for a route from the current location for each of the supply facilities listed in step S005. For each supply facility, when the shortest route length exceeds the movable distance specified in step S003, the excluded facility specifying unit 107 specifies the supply facility as an excluded facility.

  Then, the replenishment facility specifying unit 106 determines whether or not an IC (interchange) exists inside the range shape (step S007). Specifically, the replenishment facility specifying unit 106 replaces the shape of the range specified in step S004 with a geographical range, and there is an interchange that can be switched between a general road and an automobile-only road within the range. It is determined whether or not to do. If there is no interchange, the supply facility specifying unit 106 advances the control to step S009.

  When an IC (interchange) exists inside the shape of the range (in the case of “Yes” in step S007), the replenishment facility specifying unit 106 can enter and reach each IC that exists. A supply facility is specified (step S008). Specifically, the replenishment facility specifying unit 106 uses the facility information table 300 to specify a replenishment facility that exists along the destination road that has moved through the IC. In this process, if the road ahead of the IC is an automobile-only road, the supply facility specifying unit 106 refers to the automobile-only road link 304 and the information on the car-only road link 304 is linked to the car-only road. Identify supply facilities that indicate what to do.

When the shortest route length of the replenishment facility exceeds the movable distance specified in step S003, the replenishment facility specifying unit 106 does not set the replenishment facility as an additional facility and does not exceed the movable distance. The supply facility specifying unit 106 specifies the supply facility as an additional facility.

  Next, the replenishment facility specifying unit 106 performs a non-business hours facility specifying process described later (step S009). By the non-business hours facility specifying process, the supply facility specifying unit 106 excludes supply facilities that cannot arrive within business hours.

Specifically, the excluded facility specifying unit 107 acquires information on the business hours 305 of the facility information table 300 for the facilities specified in step S101, and determines whether information specifying the business hours is included. judge.

  If the information specifying the business hours is not included for the replenishment facility ("No" in step S102), the excluded facility specifying unit 107 displays the business hours unknown on the replenishment facility specified in step S101. Information is associated (step S103). Then, the excluded facility specifying unit 107 advances the control to step S106.

  When information specifying the business hours is included for the supply facility (“Yes” in step S102), the excluded facility specifying unit 107 specifies the estimated arrival time at the supply facility (step S104). ). Specifically, the excluded facility specifying unit 107 requests the basic control unit 101 to search for a route to the replenishment facility for the replenishment facility that includes information for specifying business hours. Then, the excluded facility specifying unit 107 determines whether or not the estimated arrival time at the supply facility is outside business hours.

  When it reaches within the business hours of the replenishment facility (in the case of “Yes” in step S105), the excluded facility specifying unit 107 includes all the facilities that are replenishment facilities and are not excluded facilities, and additional facilities. It is determined whether or not business hours have been determined for (step S106). If all the facilities have not been determined, the excluded facility specifying unit 107 returns the control to step S101. If all the facilities have been determined, the excluded facility specifying unit 107 performs the non-business hours facility specifying process. Terminate.

  When it does not reach within the business hours of the replenishment facility (in the case of “No” in step S105), the excluded facility specifying unit 107 sets the replenishment facility as an excluded facility (step S107). Then, the excluded facility specifying unit 107 advances the control to step S106.

  The above is the processing flow of the facility specifying process outside business hours. According to the facility identification process outside business hours, as a result of searching for a route within a predetermined range of replenishment facilities, a replenishment facility located at a distance exceeding the movable distance is searched and specified as a facility to be excluded from the display.

Icons are displayed on the map by solid lines or dark lines at the positions of the replenishment facilities 510A and 510D included in the circular range. Note that supply facilities 505A to 505D, 510B, 510C, 510E, 520A, and 520B exist outside the range 701, but these icons are excluded from the display.

  FIG. 11 shows the replenishment facility display displayed in the replenishment facility display process according to the first embodiment of the present invention when the movable distance is long, that is, the movable distance is not different from the fully charged movable distance by a certain amount. It is a screen example 500 of the screen.

  The screen example 500 in FIG. 11 is basically the same as the screen example 500 in FIG. However, as a result of the route search, the supply facility 805A included in the fan-shaped range 501 is determined to be unreachable within the movable distance, and is therefore excluded from the display.

  FIG. 12 shows the replenishment facility display displayed in the replenishment facility display process according to the first embodiment of the present invention when the movable distance is long, that is, the movable distance is not different from the fully charged movable distance by a certain amount. It is a screen example 500 of the screen.

  The screen example 500 in FIG. 12 is basically the same as the screen example 500 in FIG. However, the fan-shaped area 501 includes the interchange 902 of the highway 901, and the replenishment facility 920B that travels from the interchange 902 to the right side of the screen on the highway 901, as a result of the route search, can move the distance. It is determined that it can be reached within, and is therefore displayed as an additional facility. In addition, the replenishment facility 520A that travels from the interchange 902 to the upper left of the screen on the highway 901 is not an additional facility because it is not reachable within the movable distance as a result of the route search. Excluded from display.

  The first embodiment of the present invention has been described above. According to the first embodiment of the present invention, more appropriate replenishment can be supported by displaying a replenishment facility according to the need for replenishment.

  The present invention is not limited to the above embodiment. The first embodiment described above can be variously modified within the scope of the technical idea of the present invention. For example, in the first embodiment, the range is specified using the display shape table 400 in step S004, but the present invention is not limited to this. That is, for example, a fan-shaped interior angle that is inversely proportional to the remaining amount may be obtained by inputting the remaining amount of the power source. That is, a more detailed fan-shaped shape may be specified according to a small decrease in the remaining amount. By doing in this way, a range can be changed smoothly according to the change of remaining amount.

  Further, for example, in the first embodiment described above, the sector range is specified using the display shape table 400 in step S004, but the present invention is not limited to this. That is, for example, when the remaining amount is sufficiently large, an ellipse having a certain aspect ratio and a long axis length is a movable distance, and the long side is disposed in front of the traveling direction. Specify the range with. When the remaining amount is small, the aspect ratio of the shape is changed to shorten the difference between the length of the short axis and the length of the long axis, and the current location is placed on the long axis to specify the range. You may do it. In such a case, if the remaining amount falls below a predetermined lower limit, the length of the major axis and the length of the minor axis are the same, that is, as a perfect circle, the current location is arranged at the center of the circle. The range may be specified.

  FIG. 13 shows such a modified example, and is a screen example 500 ′ when the remaining amount is sufficiently large. The screen example 500 ′ is basically the same as FIG. 8, but the range 501 has an elliptical shape with the range 501 ′. Therefore, the supply facility 505A is excluded from the display.

  FIG. 14 shows such a modified example, and is a screen example 600 ′ when the remaining amount is low. Screen example 600 ′ is basically the same as FIG. 9, but range 601 has an elliptical shape of range 601 ′, and the distance from the current location within the ellipse to the ellipse is the front in the traveling direction. Longest. Therefore, supply facilities 505C, 510A, and 510C are excluded from the display.

  By deforming in this way, replenishment facilities in front of the traveling direction with a high possibility of traveling can be displayed more preferentially than in the left-right direction that tends to be a detour.

  Further, for example, in the first embodiment, the second embodiment, and the respective modified examples, the position of the home where sufficient replenishment can be performed is irrelevant, but may be related. For example, when the preset home position is included in the movable range, the display of the supply facility may be stopped. In this way, the home can be prioritized near the home.

  In addition, for example, in the first embodiment, the second embodiment, and the respective modifications, affiliated stores that can perform sufficient replenishment or replacement with a fully charged battery while riding a rental car or the like. It is irrelevant to the position of, but may be related to these. For example, in a case where the preset vehicle sequence information is included in the supply facility sequence, the supply facility in the range within the range may be displayed. By doing in this way, quicker replenishment can be performed.

  Further, for example, in the first embodiment, the second embodiment, and the respective modified examples, it is irrelevant to the number of replenishment facilities existing in the range, but may be associated with this. For example, when there is only one replenishment facility in the range, the basic control unit 101 may set the replenishment facility as a waypoint and guide the route. By doing so, the risk of getting stuck due to insufficient replenishment can be reduced.

  In addition, for example, in the first embodiment, the second embodiment, and the respective modifications, the exclusion is determined according to whether or not it can arrive within business hours, but it arrives within business hours. However, if the waiting time until the start of replenishment is long, replenishment cannot be performed substantially, so that the facility may also be excluded. For example, statistical information on the average waiting time of the replenishment facility may be acquired via a wireless communication network (not shown), and the estimated arrival time may be lowered by the average waiting time. By doing so, it is possible to reduce the risk of getting stuck due to insufficient supply.

  In addition, for example, in the first embodiment, the second embodiment, and the respective modifications, there is an IC within the range, and the supply facility is attached to the road that has advanced from the IC. If it is reachable, the supply facility is displayed as an additional facility, but for supply facilities that cannot be reached within the movable distance, guidance information is displayed so as to avoid entering the IC. Also good. By doing in this way, the risk that it cannot be replenished at the point of entry from the IC and gets stuck can be reduced.

  In addition, for example, in the first embodiment, the second embodiment, and the respective modifications, there is an IC within the range, and the supply facility is attached to the road that has advanced from the IC. If it is reachable, the supply facility is displayed as an additional facility. However, not only for ICs, but also for entrances to roads that do not have avoidance routes such as bridges, roads that have advanced from the entrance If it is possible to reach the replenishment facility attached to the facility, the replenishment facility may be displayed as an additional facility. By doing in this way, the risk that it cannot be replenished at the point of entry from the entrance of a bridge or the like and gets stuck can be reduced.

  In the above, this invention was demonstrated centering on embodiment. In each of the above-described embodiments, description has been made on the assumption that a mobile body (for example, an electric vehicle) using electric power as a power source is supplied (charging by a charging stand). It can be applied to replenish the power source of the whole body.
