Description

  The present invention relates to a telematics service for electric vehicles, and more particularly to a system for providing means for distributing charging facility information.

Various efforts have been started on a global scale to deal with environmental problems, and the automobile industry is active in reducing CO2 emissions. Mainly in the EU, the introduction of a levy system for vehicles that violate CO2 emission regulations, the transition of automobile tax based on emissions to the CO2 emission standard, and subsidy systems for the acquisition of environmentally friendly vehicles such as hybrid cars and electric cars It has been. In parallel with environmental issues, in 2008, the rise in crude oil prices increased the need for fossil fuels in the transportation sector, and general consumers are now paying attention to environmentally friendly vehicles. In particular, government agencies, Japan Post, and electric power companies are planning to switch electric vehicles to public vehicles and commercial vehicles. Each car manufacturer is focusing on electric vehicle development, and commercial vehicle sales of electric vehicles started in 2009. Sales of electric cars for general public are scheduled for '10 years.

  The challenge in the current popularization of electric vehicles is the maintenance of infrastructure including battery performance, price and charging facilities. The cruising range of an electric vehicle is as short as a few tens of kilometers, and it is thought that it will be popularized for use as a public commuter and commercial vehicle, which are closed within the cruising range, and as a city commuter with a relatively short moving distance. . In the future, replacing electric vehicles with current gasoline vehicles will require charging facilities in parallel with technological development of the batteries themselves. With the assistance of the national and local governments, the charging business is starting up mainly by electric power companies. Highways, gas stations and convenience stores are beginning to install chargers, and networking chargers to guide them to charging facilities that can use electric vehicles is also being considered.

The following processing is performed for each information collected from the electric vehicle 102 currently being processed and registered in the temporary recording DB 221. When the position attribute is “unknown” (step 900), the registration information is deleted from the temporary recording DB 221 (step 905). If the position attribute is other than “unknown”, it is determined whether or not there is information on a plurality of electric vehicles 102 with respect to the position information (step 901). It is determined whether or not the total value is equal to or greater than a predetermined threshold value (step 902). If the total number of usages is greater than or equal to the threshold value, the entity confirms the location information to the charging facility, confirms the presence / absence of a membership system, the number of charging devices, availability of the general public, available time, holiday information, etc. and charging Negotiate information disclosure of facilities, etc., and set a negotiation flag.

When data is received from the in-vehicle device 405 mounted on the electric vehicle 102 and the received data is a charging facility information request (step 1000), from the identifier of the electric vehicle 102 or the in-vehicle device 405 included in the charging facility information request, Member information is searched in the member DB 320 (step 1001). The charging facility information request includes the identifier of the electric vehicle 102 or the vehicle-mounted device 405, current location information, remaining battery capacity, destination, and the like. The member information includes the identifier of the electric vehicle 102 or the vehicle-mounted device 405, the attribute of the vehicle, the owner's name, address, telephone number, lease information and the like. The attribute of the vehicle indicates whether the vehicle is an individual contract, a corporate contract, or used as a lease or rental vehicle. When the vehicle is a lease vehicle or a rental vehicle, the lease information indicates the user and the use time zone when the user who uses the lease and the use time zone are known. The member information acquired from the member DB 320 and the current location information included in the charging facility information request are acquired (step 1002). The present location information, the remaining battery level included in the charging facility information request, and the charging facility POI request message are generated and transmitted to the charging infrastructure information service portal 100 (step 1003). The charging facility POI request message is calculated from the remaining battery level in addition to the identifier, vehicle attribute, lease information, current location information, destination, etc. of the electric vehicle 102 or vehicle-mounted device 405 notified by the charging facility information request. Includes reachable distance. When the charging facility POI response message is received from the charging infrastructure information service portal 100 (step 1004), the charging facility information included in the charging facility POI response message is converted into a format that can be handled by the in-vehicle device 405, and the charging facility information response message is displayed. Generate and transmit to the vehicle-mounted device 405 (step 1005). When data is received from the charging infrastructure information service portal 100 and the received data is a map / facility information request message for the location information (step 1006), the location information included in the request message is converted into the map DB 321 and the facility POI-DB 322. The search is performed (step 1007). When there is facility information corresponding to the location information (step 1008), a location information acquisition response message including the facility information is generated and transmitted to the charging infrastructure information service portal 100 (step 1010). If there is no facility information for the position information, the facility information is set to “unknown” (step 1009), and a position information acquisition response message is generated and transmitted to the charging infrastructure information service portal 100.
