Abstract

A vehicle information providing device provides route information to vehicles. The vehicle information providing device has a history information accumulation unit that sequentially acquires at least one of driving location information, power consumption information and charging location information from vehicle-mounted devices of a plurality of vehicle, and accumulates this as driving history information. A composite route generation unit generates a composite route by combining a plurality of routes traveled by the same vehicle or by a plurality of vehicles. A presentation information provision unit provides information regarding the composite routes that are generated by the composite route generation unit. The composite route generation unit extracts information regarding the travel start and end points of the routes included in the driving history information when generating the composite route and combines the routes for which the travel end points and the travel start points are within a predetermined spatial range.

Claims

1. A vehicle information providing device comprising:

a history information accumulation unit that sequentially acquires at least one of driving location information, power consumption information and charging location information from vehicle-mounted devices installed on a plurality of vehicles that each have an electric motor as a drive source and accumulates this information as the driving history information;

a composite route generation unit that generates a composite route by combining a plurality of routes that are driven by the same vehicle by referencing the driving history information that is accumulated by the history information accumulation unit; and

a presentation information provision unit that provides information regarding a composite route generated by the composite route generation unit,

the composite route generation unit extracting from information regarding a travel start point and a travel end point of each route included in the driving history information when generating the composite route and combines routes having travel end points and travel start points within a predetermined spatial range.

2. The vehicle information providing device as recited in claim 1, further comprising:

a planned route acquisition unit that acquires a planned route from a departure point to a destination point;

a first presentation route determination unit that searches for a composite route that is identical or similar to the planned route that is acquired by the planned route acquisition unit from the composite routes that are generated by the composite route generation unit and determines the searched composite route to be a first presentation route; and

a first presentation information determination unit that determines at least one of the power that is consumed when driving along the first presentation route and charging hubs that will be traversed when driving along the first presentation route by referencing the driving history information that is accumulated in the history information accumulation unit;

the presentation information provision unit providing information regarding determination results of the first presentation route determination unit and determination results of the first presentation information determination unit as composite route information.

3. The vehicle information providing device as recited in claim 2, further comprising:

a second presentation route determination unit that determines a route that is identical or similar to the planned route that is acquired by the planned route acquisition unit as a second presentation route, within single routes that are routes traveled by one vehicle at once, by referencing the driving history information that is accumulated by the history information accumulation unit; and

a second presentation information determination unit that determines at least one of the power that is consumed when driving along the second presentation route and the charging hubs that will be traversed when driving along the second presentation route by referencing the driving history information that is accumulated in the history information accumulation unit;

the presentation information provision unit providing information regarding determination results of the second presentation route determination unit and determination results of the second presentation information determination unit, along with information regarding the determination results of the first presentation route determination unit and the determination results of the first presentation information determination unit.

4. The vehicle information providing device as recited in claim 2, further comprising:

a second presentation route determination unit that determines a route that is identical or similar to the planned route that is acquired by the planned route acquisition unit as a second presentation route, within single routes that are routes traveled by one vehicle at once, by referencing the driving history information that is accumulated by the history information accumulation unit; and

a second presentation information determination unit that determines at least one of the power that is consumed when driving along the second presentation route and the charging hubs that will be traversed when driving along the second presentation route by referencing the driving history information that is accumulated in the history information accumulation unit;

the presentation information provision unit providing information regarding the determination results of the second presentation route determination unit and the determination results of the second presentation information determination unit if a second presentation route can be determined by the second presentation information determination unit and provides information regarding the determination results of the first presentation route determination unit and the determination results of the first presentation information determination unit if the second presentation route cannot be determined by the second presentation information determination unit.

5. The vehicle information providing device as recited in claim 1, wherein

the composite route generation unit refers to information regarding a travel start point and a travel end point of each route included in the driving history information when generating the composite route and combines the routes having travel end points and travel start points within a predetermined distance range.

6. The vehicle information providing device as recited in claim 1, wherein

the composite route generation unit refers to information regarding a travel start point and a travel end point for each route included in the driving history information when generating the composite route, performs an indexing operation in an area in which a travel start point and a travel end point of each route is divided into predetermined ranges, and combines the routes for which the travel end points and the travel start points belong to the same index.

7. The vehicle information providing device as recited in claim 1, wherein

the composite route generation unit records at least one of the information regarding large-scale facilities of a predetermined scale or greater and information regarding chargeable facilities equipped with public charging facilities, and

the composite route generation unit sets a priority to be higher as the distance between a travel start point and a travel end point at a combined point of a plurality of routes used for generating the composite route become closer, and

the first presentation route determination unit selects the first presentation route, in consideration of the priority of the composite route, when determining the first presentation route from the composite routes.

11. The vehicle information providing device as recited in claim 8, wherein

the composite route generation unit sets a priority to be higher as the travel conditions of a plurality of routes used for generating the composite route become more similar, and

the first presentation route determination unit selects the first presentation route, in consideration of the priority of the composite route, when determining the first presentation route from the composite routes.

12. The vehicle information providing device as recited in claim 10, wherein
