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. The vehicle information providing device has a presentation information provision unit that provides information regarding a presentation route in which the information regarding the presentation route is presented in a form such that routes in a vicinity of the private location cannot be identified, when the presentation route is determined to include at least one private location.

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 as driving history information;

a private location detection unit that detects a private location determined to pertain to privacy along a route that each of the vehicle drives by referencing the driving history information that is accumulated by the history information accumulation unit;

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

a presentation route determination unit that determines a presentation route that is identical or similar to the planned route that is acquired by the planned route acquisition unit by referencing the driving history information that is accumulated by the history information accumulation unit;

a privacy determination unit that determines whether or not a presentation route determined by the presentation route determination unit includes one or more private locations;

a presentation information determination unit that determines at least one of the power that is consumed when driving along the presentation route determined by the presentation route determination unit and charging hubs that will be traversed when driving along the presentation route determined by the presentation route determination unit; and

a presentation information provision unit that provides information regarding the presentation route, the determination results of the presentation route determination unit, and the determination results of the presentation information determination unit;

wherein

when the presentation route is determined to include at least one of the private locations, the presentation information provision unit provides information regarding the presentation route in a form such that routes in a vicinity of the private location cannot be identified.

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

when the presentation route is determined to include at least one of the private locations, the presentation information provision unit provides information regarding the presentation route in a form such that the routes in the vicinity of the private location and the routes that are within a predetermined distance range from the departure point or the destination point cannot be identified.

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

when the presentation route is determined to include at least one of the private locations, the presentation information provision unit provides information regarding the presentation route in a form such that routes that are within a predetermined distance range from the private location cannot be identified.

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

the privacy determination unit detects locations at which a stay frequency or a stay time is equal to or greater than a predetermined threshold for each of the vehicles by referencing the driving history information that is accumulated by the history information accumulation unit and determines the locations to be one of the private locations.

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

the privacy determination unit detects U-turn locations for each of the vehicles by referencing the driving history information that is accumulated by the history information accumulation unit and determines the U-turn locations to be one of the private locations.

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

a composite route generation unit that generates one or more composite routes 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,

the private location detection unit is configured to detect the private locations in the composite routes that are generated by the composite route generation unit by referencing the driving history information that is accumulated by the history information accumulation unit, and

the presentation route determination unit searches for a composite route of the composite routes 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 presentation route.

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

when a determination is made that the determined presentation route includes at least one of the private locations, the presentation route determination unit searches for a route that is identical or similar to the determined presentation route and that does not include one of the private locations by referencing the driving history information that is accumulated by the history information accumulation unit and determines the searched route to be a presentation route instead of the presentation route that is determined to include the private location.

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

when the number of routes that are identical or similar to the presentation route, which is determined by the presentation route determination unit, is equal to or less than a predetermined number, or when the presentation routes that are identical or similar to the presentation route, which is determined by the presentation route determination unit, are routes from only a single vehicle, the presentation information provision unit does not provide the information.
