The control unit 180 executes the route guidance program 200. FIG. 4 is a diagram showing a functional configuration of the route guidance program 200 according to the embodiment of the present invention. The route guidance program 200 includes a route search unit 202, a charging road detection unit 204, a route recontrol unit 206, a route cost determination unit 208, a battery remaining amount acquisition unit 210, a battery consumption calculation unit 212, a travelability determination unit 214, and charging. It is equipped with a lane information acquisition unit 216 and a route guidance output unit 218.

The route search unit 202 searches for a route from the current location or a designated point to the destination. The charging road detecting unit 204 detects whether or not the charging road is included in the route searched by the route searching unit 202. The location information of the charging road is acquired from the charging facility DB172. When the charging road detection unit 204 detects the charging road on the search route, the re-search control unit 206 causes the route search unit 202 to search again for the route to the destination avoiding the charging road.

The route cost determination unit 208 determines whether the route cost such as the traveling time and the power consumption does not exceed a predetermined value in the route avoiding the charging road as compared with the route including the charging road. The battery remaining amount acquisition unit 210 acquires the remaining amount information of the battery 20 via the external I / F 140. The battery consumption calculation unit 212 calculates the battery consumption required for traveling to the destination on the route avoiding the charging road. In the calculation of the battery consumption, the consumption including the link data such as slopes and curves stored in the map data is calculated.

The travelability determination unit 214 can travel to the destination using the route avoiding the charging road with the current remaining battery power, or charge when arriving at the destination using the route avoiding the charging road. Determine if the amount is less than or equal to the 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 provides guidance on 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, the destination is set according to the instruction from the user (S100). When this destination is set, the route guidance program 200 is started. First, the route search unit 202 searches for a route from the position of the own vehicle or a designated point to the destination (S102). The route search is, for example, using the link data and node data stored in the map DB 171 to minimize the total link cost of each link in a continuous link from the current location or a specified point to the destination. Search for a route. Further, in the route search, it is possible to search a plurality of routes in consideration of various conditions (for example, mileage priority, expressway priority, general road priority). Further, in the case of a navigation device corresponding to an electric vehicle, the route search may search for a route that gives priority to the charging facility.

When the route to the destination is searched, next, whether or not the search route includes the charging road is detected by the charging road detection unit 204 (S104). The position information of the charging road is acquired from the charging facility DB172, and it is detected whether or not there is a charging road on the search route. However, the information about the charging road may be acquired from an external distribution site (distribution server) via the communication unit 130.

When the search route does not include the charging road, the route guidance output unit 218 determines the search route as it is as a guidance route and guides the user to this route (S106). When the search route includes the charging road, the re-search control unit 206 causes the route searching unit 202 to re-search the route that does not include the charging road in the route to the destination in response to the detection result (S108). ). Then, at this time, data such as a route including a charging road, a traveling time, and a power consumption amount are recorded in the route data holding unit 173.

When searching for a route that avoids the charging road, information about the charging road including location information is acquired from the charging facility DB172, and the total link cost is the smallest without going through the position of the link that overlaps the position of the charging road. Calculate the route. Alternatively, when the charging road information is stored in the link data of the map data, the route that does not go through the link data including the charging road and has the smallest total link cost may be calculated. Information about 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 determines the route cost of the route avoiding the charging road (S110). First, the estimated travel time to the destination on the route avoiding the charging road is calculated, and the comparison determination with the estimated traveling time to the destination on the route including the charging road recorded in the route data holding unit 173 is performed. If it is determined that the predicted travel time on the route avoiding the charging road is longer than the predicted traveling 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 to the destination on the route avoiding the charging road is calculated, and the comparison judgment with the predicted power consumption to the destination on the route including a certain charging road recorded in the route data holding unit 173 is made. conduct. If the predicted power consumption in the route avoiding the charging road is larger 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 the route cost, and the process proceeds to S118. The predetermined amount may be set in advance, for example, 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 one or the other. Further, it may be determined whether or not there is a problem in terms of route cost from items other than the above-mentioned determination target. If it is determined that there is no problem, proceed to the next step.

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

Preferably, the acquired remaining battery level is compared with the battery consumption required to travel on the route avoiding the charging road calculated by the battery consumption calculation unit 212, and the route avoiding the charging road is traveled. If it is determined that the expected remaining battery level does not fall below the predetermined value when the vehicle arrives at the destination, it is determined that the vehicle can run and the process proceeds to the next step. The predetermined value of the expected remaining battery level may be a preset value such as 70% or more, or may be set by the user.

In this embodiment, the battery consumption in the route traveling avoiding the charging road was calculated, but instead of this, the cruising distance with the current remaining battery level is calculated, and the cruising distance and the charging road are calculated. It may be determined whether or not it is possible to reach the destination by comparing the total distances of the routes avoiding the above.

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

In one embodiment, the route guidance output unit 218 may simultaneously display a route including the charging road and a route avoiding the charging road as candidate routes, and finally let the user select the route. FIG. 6 shows an example of displaying a route including the charging road and a route avoiding the charging road. The route including the charging road is A, and the route avoiding the charging road is B. As shown in the figure, if 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 becomes easy to understand which is the route avoiding the charging road at first glance. .. Further, it may be shown that the route B avoiding the charging road can be selected so that the final decision can be made by the user.

Also, when recommending a route that avoids the charging road, make the input button for selecting the road that avoids the charging road more prominent than the input button for selecting another road, or automatically make the charging road. An input button for selecting the avoided route may be selected. In that case, a sentence or voice may be output to the effect that the vehicle can travel on a route avoiding the charging road. Further, even if it is determined in S110 that there is a problem in terms of cost and cost, or even if it is determined in S114 that the vehicle cannot travel, the route avoiding the charging road can be selected as a note. , The reasons why it is not recommended, such as running time, power consumption, and insufficient cruising range due to the remaining battery power, may be explained by text or voice.

Next, when it is determined in S110 that there is a problem in terms of cost, or when it is determined in S114 that the vehicle cannot travel, the charging lane information acquisition unit 216 responds to the determination result by the charging facility. The charging lane information is acquired from DB172 (S118). The charging lane information acquisition unit 216 may acquire charging lane information from an external distribution site (distribution server) via the communication unit 130. Then, route guidance is performed on the route including the charging road based on the acquired charging lane information (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, lanes other than the charging lane are highlighted or voiced to provide route guidance to avoid the charging lane.

When it is determined that the vehicle cannot travel on the route avoiding the charging road of S114, the user charges the battery by stopping at the charging facility or traveling on the charging road, and the predetermined amount of charge required when arriving at the destination. When it reaches, the re-search control unit 206 detects the charge of a predetermined value or more from the battery remaining amount acquisition unit 210, and in response, causes the re-search control unit 206 to re-search the route avoiding the charging road so that the vehicle can travel. You may do so.

Alternatively, when searching for a route 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 obtains the charging amount by using the charging road and then the charging amount. Search for a route that avoids the charging road including some charging roads, where the remaining battery level at the time of arrival at the destination does not fall below the predetermined value by passing through the charging road from the power consumption due to the route driving avoiding the charging road. You may try to do it.

FIG. 8 shows an example of displaying a route avoiding the charging road including a part of the charging road. The figure shows a route avoiding the charging road 30B after using the charging route 30A closest to the current position, but the charging road 30B near the destination G may be driven, and when the destination is reached. It suffices to prevent the remaining battery level of the above-mentioned predetermined value from falling below the above-mentioned predetermined value. A plurality of routes may be searched, 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 was calculated, but the route avoiding the charging road avoiding not only the charging road but also all the charging facilities such as the charging stand is calculated. May be good. This also makes it possible to avoid congestion in the vicinity of the charging facility caused by a long charging time.

The present invention is also applicable to a vehicle not provided with the storage battery 20, in which case the battery remaining amount acquisition unit 210, the battery consumption calculation unit 212, and the runnability determination unit 214 are not executed or unnecessary. That is, if it is determined that there is no problem in the route cost of the route avoiding the charging road in S110 of FIG. 5, the processing of S112 and S114 is skipped, and the process shifts to S116 to use the charging road. Guide the avoided route. By doing so, it can be adapted to other than electric vehicles, and it becomes possible to provide a route that avoids charging facilities.

In this embodiment, the route guidance program 200 is executed by the navigation device 100 mounted on the car. 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 embodiments of the present invention have been described in detail, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the gist of the invention described in the claims. It is possible.
