  The route search unit 202 searches for a route from the current location or a specified point to the destination. The charging road detection unit 204 detects whether or not a charging road is included on the route searched by the route search unit 202. The charging road position information is acquired from the charging facility DB 172. When the charging road detection unit 204 detects a charging road on the searched route, the re-search control unit 206 causes the route searching unit 202 to search again for a route to the destination avoiding the charging road.

  The route cost determination unit 208 determines whether a route cost such as travel time and power consumption is equal to or higher than a predetermined value compared to a route including the charging road when the route avoiding the charging road. The battery remaining amount acquisition unit 210 acquires remaining amount information of the battery 20 via the external I / F 140. The battery consumption calculation unit 212 calculates the battery consumption necessary for traveling to the destination on the route avoiding the charging road. In the calculation of the battery consumption, the consumption is calculated in consideration of link data such as slopes and curves stored in the map data.

  The travelability determination unit 214 can use the current battery level to travel to the destination using the route avoiding the charging road, or charge when arriving at the destination using the route avoiding the charging road. It is determined whether the amount does not fall below a predetermined value. The charging lane information acquisition unit 216 acquires information on the lane position and section of the charging lane included in the charging road from the charging facility DB 172. The route guidance output unit 218 performs guidance for the determined route.

  The operation of the navigation device according to the embodiment of the present invention will be described with reference to the flowchart of FIG. First, a destination is set according to an instruction from the user (S100). When this destination is set, the route guidance program 200 is activated. First, the route search unit 202 searches for a route from the vehicle position or a specified point to the destination (S102). The route search is, for example, that the sum of the link cost of each link is the minimum in a continuous link from the current location or a specified point to the destination using link data and node data stored in the map DB 171. Search for a route. In the route search, a plurality of routes can be searched in consideration of various conditions (for example, travel distance priority, highway priority, general road priority). Furthermore, in the case of a navigation device corresponding to an electric vehicle, the route search may search for a route that prioritizes the charging facility.

  When the route to the destination is searched, the charging road detection unit 204 detects whether or not the searched route includes the charging road (S104). The charging road position information is acquired from the charging facility DB 172, and it is detected whether there is a charging road on the searched route. However, the information regarding the charging road may be acquired from an external distribution site (distribution server) via the communication unit 130.

  When the searched route does not include the charging road, the route guidance output unit 218 determines the searched route as it is as the guidance route and guides this route to the user (S106). When the searched route includes a charging road, in response to the detection result, the re-search control unit 206 causes the route searching unit 202 to re-search for a route that does not include the charging road in the route to the destination (S108). ). At this time, the route data holding unit 173 records data on the route including the charging road, the travel time, the power consumption, and the like.

  When searching for a route avoiding the charging road, information on the charging road including the position information is acquired from the charging facility DB 172, and the sum of the link costs is the smallest without passing through the position of the link overlapping the position of the charging road. The route that becomes is calculated. Alternatively, when the charging road information is stored in the link data of the map data, a route that does not pass through the link data including the charging road and has the smallest sum of link costs may be calculated. Information on the charging road may be acquired from an external distribution site (distribution server) via the communication unit 130.

  Next, the route cost determination unit 208 makes a determination regarding the route cost of the route avoiding the charging road (S110). First, the predicted travel time to the destination on the route avoiding the charging road is calculated, and the determination is made with the predicted travel time to the destination on the route including the charging road recorded in the route data holding unit 173. If it is determined that the predicted travel time on the route avoiding the charging road is longer than the predicted travel time on the route including the charging road by a predetermined time or more, it is determined that there is a problem in the route cost, and the process proceeds to S118. The predetermined time may be set in advance, for example, 30 minutes or may be set by the user.

  Next, the predicted power consumption up to the destination on the route avoiding the charging road is calculated, and the comparison determination with the predicted power consumption up to the destination on the route including the certain charging road recorded in the route data holding unit 173 is performed. Do. If the predicted power consumption in the route avoiding the charging road is greater than the predicted power consumption in the route including the charging road by a predetermined amount or more, it is determined that there is a problem in route cost, and the process proceeds to S118. The predetermined amount may be set in advance, such as 30%, or may be set by the user.

  In another embodiment, the route cost determination unit 208 may compare both the travel time and the power consumption described above, or may compare either one. Further, it may be determined whether there is no problem in the route cost based on other than the determination target described above. If it is determined that there is no problem, the process proceeds to the next step.

  In S110, in response to the determination that the route avoiding the charging road has no problem in route cost, the remaining amount of the battery 20 is acquired by the remaining battery amount acquisition unit 210 (S112). Next, based on the acquired battery remaining amount and the route avoiding the charging road, the travel enable determination unit 214 can travel to the destination using the route avoiding the charging road from the current battery remaining amount. It is determined whether or not (S114).

  Preferably, the acquired battery remaining amount is compared with the battery consumption required to travel on the route avoiding the charging road calculated by the battery consumption calculating unit 212, and the vehicle travels on the route avoiding the charging road. If it is determined that the remaining battery level expected at the time of arrival at the destination does not fall below the predetermined value, it is determined that traveling is possible and the process proceeds to the next step. The predetermined value of the expected remaining battery level may be set in advance such as 70% or more, or may be set by the user.

  In the present embodiment, the battery consumption in the route travel avoiding the charging road is calculated. Instead, the cruising distance in the current battery remaining amount is calculated, and the cruising distance and the charging road are calculated. It is also possible to determine whether or not it is possible to reach the destination by comparing the total distances of the routes avoiding the above.

  If it is determined in S114 that the route avoiding the charging road can be traveled, the route guidance output unit 218 guides the route avoiding the charging road as a guidance route to the user (S116). Thus, when a charging road is included on the route to the destination, a route that avoids the charging road is automatically searched.

  In an embodiment, the route guidance output unit 218 may simultaneously display a route including a charging road and a route avoiding the charging road as candidate routes, and finally allow the user to select a route. In FIG. 6, a route including a charging road and a route including a charging road showing a display example of a route avoiding the charging road are A, and a route avoiding the charging road is B. As shown in the figure, when the route A including the charging road, the route B avoiding the charging road, and the charging road 30 existing on the route are also displayed at the same time, it is easy to understand which is the route avoiding the charging road. . In addition, the user may make a final decision by presenting that the route B avoiding the charging road can be selected.

  Also, when recommending a route that avoids the charging road, the input button for selecting the road that avoids the charging road is made more prominent than the input button for selecting another road, or the charging road is automatically selected. An input button for selecting the avoided route may be selected. In that case, you may make it output by a sentence and a voice that it can drive | work the path | route which avoided the charging road. Furthermore, even if it is determined that there is a problem in expense cost in S110, or even if it is determined that traveling is not possible in S114, it is possible to select a route that avoids the charging road as an annotation. The reason why the travel time, the power consumption, the cruising distance shortage due to the remaining amount of the battery, etc., which are not recommended, may be explained by sentences or voices.

  Next, when it is determined in S110 that there is a problem in terms of cost or when it is determined in S114 that traveling is not possible, in response to the determination result, the charging lane information acquisition unit 216 Charge lane information is acquired from DB172 (S118). Charging lane information acquisition unit 216 may acquire charging lane information from an external distribution site (distribution server) via communication unit 130. Then, route guidance on the route including the charging road based on the acquired charging lane information is performed (S120). FIG. 7 shows a display example of route guidance in consideration of the charging lane according to the embodiment of the present invention. As shown in the figure, route guidance for avoiding the charging lane is performed by highlighting lanes other than the charging lane or informing by voice.

  In addition, when it is determined that traveling on the route avoiding the charging road in S114 is impossible, charging is performed by the user by dropping in to the charging facility or traveling on the charging road, and the predetermined charging amount required upon arrival at the destination In the case of reaching the above, the re-search control unit 206 detects charging exceeding a predetermined value from the battery remaining amount acquiring unit 210 and, in response, re-searches for a route avoiding the charging road that can be run. You may do it.

  Alternatively, at the time of route search avoiding the charging road, the re-search control unit 206 acquires information on the charging amount obtained by traveling on each charging road from the charging facility DB 172, and the charging amount by using the charging road and thereafter Search for routes avoiding charging roads, including some charging roads, where the remaining battery level at arrival at the destination does not fall below a predetermined value via the charging roads, based on the power consumption of the route driving that avoids charging roads You may make it do.

  A display example of a route that avoids a charging road including a part of the charging road is shown in FIG. Although the figure shows a route that avoids the charging road 30B after using the charging route 30A that is closest to the current position, it may be allowed to travel on the charging road 30B that is close to the destination G. What is necessary is just to make it the battery remaining amount of less than the above-mentioned predetermined value. A plurality of routes may be searched for, and the route with the shortest travel time may be used as the guide route.

  In the above embodiment, the route avoiding the charging road only for the charging road is calculated, but not only the charging road but also the route avoiding the charging road that avoids all charging facilities such as the charging station is calculated. Also good. Thereby, it is also possible to avoid the congestion near the charging facility caused by the long charging time.

  Note that the present invention can also be applied to a vehicle that does not include the storage battery 20, and in this case, the remaining battery level acquisition unit 210, the battery consumption calculation unit 212, and the travelability determination unit 214 are not executed or unnecessary. In other words, if it is determined that there is no problem in the route cost in the route avoiding the charging road in S110 of FIG. 5, if it is determined that there is no problem, the processing of S112 and S114 is skipped, and the processing proceeds to S116 and the charging road is Guide the avoided route. By doing so, it can be adapted to other than electric vehicles, and a route avoiding the charging facility can be provided.

  In the present embodiment, the route guidance program 200 is executed by the navigation device 100 mounted on the car. However, the present invention is not limited to this, and the communication unit 130 is connected to a server having an external calculation function for information on the destination and the current location. The external server may execute the route guidance program 200 to receive the searched guidance route from the communication unit 130, and the navigation device 100 may perform route guidance based on the received guidance route.

  Although the preferred embodiment of the present invention has been described in detail, the present invention is not limited to the specific embodiment, and various modifications and changes can be made within the scope of the gist of the invention described in the claims. Is possible.
