  According to the present invention, the user can select a desired fueling facility in consideration of both price and location.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a system configuration diagram showing an example of a main configuration of a fuel price display system 10 according to the present invention. The fuel price display system 10 of the present embodiment includes an in-vehicle information terminal 100 mounted on a vehicle, a center server 200 disposed in a center, and a fueling facility operator terminal managed by a fueling operator that provides a fueling service. 300. A plurality of refueling facility operator terminals 300 are installed for each refueling operator or for each specific group. The fuel supplier is a business operator who has signed an alliance agreement in favor of the fuel price display system 10 described in detail below. The center server 200 may be composed of a plurality of servers, but in this case also, the center server 200 functions as a single center server 200 in cooperation with each other.

  Each fueling facility operator terminal 300 is connected to the center server 200 via the Internet, for example, and is configured to be communicable with the center server 200. Each fueling facility operator terminal 300 notifies the center server 200 of the price (for example, price per liter) of fuel provided at each store (fueling facility). The price of the fuel may be notified for each type of fuel, such as gasoline, high-octane, or light oil.

  As shown in FIG. 1, the center server 200 includes a network gateway 202, an information management unit 204, and a national version fueling facility database 206. The information management unit 204 builds a nationwide version of the fueling facility database 206 based on information supplied from each fueling facility operator terminal 300. Further, as will be described later, the information management unit 204 supplies the data in the national version fueling facility database 206 to the vehicle side at a request from the vehicle side or periodically.

  FIG. 2 is a diagram illustrating an example of data stored in the national version fueling facility database 206. The national version fueling facility database 206 stores fueling facility information for each fueling facility. In the example shown in FIG. 2, only four refueling facilities around Shibuya-ku, Tokyo are representatively shown. However, in actuality, in Japan, there are a huge number from Hokkaido in the north to Okinawa in the south. Similar data relating to refueling facilities are stored.

  In the example shown in FIG. 2, the fueling facility information includes the location (address) of the fueling facility, information (sales price information) regarding the sales price of fuel (gasoline, high-octane, light oil, hydrogen, etc.) provided at each fueling facility, Includes business hours and phone number. Among these data, information (fuel price) that can change dynamically is supplied and updated from each refueling facility operator terminal 300 every day or every time there is a change.

  Next, referring again to FIG. 1, the configuration on the vehicle side will be described in detail.

  The in-vehicle information terminal 100 may be embodied as a navigation device. The in-vehicle information terminal 100 has a hardware configuration including a microcomputer including a CPU, a ROM, a RAM, and the like connected to each other via a bus (not shown) and a communication module.

  As shown in FIG. 1, the in-vehicle information terminal 100 includes a host vehicle position detection unit 102, an information output control unit 104, a fueling facility database 106, a map database 108, and a sales price information acquisition unit 110.

  A GPS antenna is connected to the vehicle position detection unit 102. The own vehicle position is measured and calculated based on a GPS signal output from a GPS satellite via a GPS antenna by a GPS receiver. The positioning method may be any method such as single positioning or relative positioning (including interference positioning). At this time, the vehicle position may be corrected based on outputs from various sensors such as a vehicle speed sensor and a gyro sensor, and various information received via the beacon receiver and the FM multiplex receiver. For example, in D-GPS (Differential GPS), which is one of relative positioning, the vehicle position is determined by calculating the distance from four or more GPS satellites, and then received at a known point. Is corrected based on the GPS correction data supplied from the machine (reference station) (so-called differential correction: GPS signal received at two points includes the same error, positioning is performed by subtracting the error. To improve accuracy.) The GPS correction data is broadcast by FM multiplexing periodically (for example, every 5 seconds) from a plurality of reference stations installed throughout the country and received by the FM multiplex receiver of the vehicle. The own vehicle position may be appropriately corrected using the map data in the map database 108 irregularly by a known map matching technique. For example, the trajectory of the own vehicle position (running trajectory) is compared with the road shape of the map data, and the vehicle position is corrected so as to come to a point on the road accordingly. The vehicle position derived in this way is supplied to the information output control unit 104 every calculation cycle.

  A display device 140 and an input device 130 are connected to the information output control unit 104. The display device 140 is a device that visually outputs information, and is a display such as a liquid crystal display. The display device 140 is disposed at a position that is easy for the user (vehicle occupant) in the vehicle compartment to see. The input device 130 may be, for example, a remote controller, a voice recognition microphone, or a display touch switch.

  The information output control unit 104 controls the output of image display on the display device 140. For example, the information output control unit 104 displays and outputs various types of information on the display device 140 in response to a request from the user input via the input device 130. The information output by the display device 140 includes map data in the map database 108 and data in the fueling facility database 106 as described later.

  The map database 108 stores map data. In the map data, as usual, coordinate information of nodes corresponding to road junctions (intersections), coordinate information of nodes corresponding to junctions / branches of expressways, and adjacent nodes are connected. It includes link information, road width information corresponding to each link, road types such as national roads, prefectural roads, and highways corresponding to each link, and various road information such as traffic restriction information for each link. In addition, road information includes speed limit for each link, temporary stop line, parking prohibited area, presence of traffic lights, presence / absence of crossings, overtaking prohibited section, one-way street, school zone, U-turn prohibition, accident frequent occurrence information, etc. It's okay. Further, the map database 108 may store POI (Point Of Interest) information including information on sightseeing spots and various facilities.

  The sales price information acquisition unit 110 receives a request from the information output control unit 104 and acquires data in the national version fueling facility database 206 via wireless communication with the center server 200. The sales price information acquisition unit 110 stores the data acquired from the center server 200 in the refueling facility database 106. The data structure in the fueling facility database 106 may be the same as the data structure in the national version fueling facility database 206 described above. However, all the data in the above-mentioned national version refueling facility database 206 may be stored in the refueling facility database 106. However, in order to increase the efficiency of the capacity, it is preferable that only the data in the necessary area is used as described later. Is acquired and stored.

  FIG. 3 is a flowchart illustrating an example of a fuel price display process realized by the in-vehicle information terminal 100 according to the present embodiment.

  As shown in FIG. 3, when the user requests a display of a peripheral facility (display of a gas station) via the input device 130 (YES determination in step 10), the information output control unit 104 supplies the fuel supply facility in which area. Decide whether facility information should be obtained. That is, the information output control unit 104 determines an area (acquisition area) where the fueling facility information should be acquired (step 20). When the information output control unit 104 determines the acquisition area, the information output control unit 104 requests data related to the fueling facility in the acquisition area to the center server 200 via the sales price information acquisition unit 110 (step 30).

  Here, the acquisition area may be designated by the user. This is because there are cases where it is desired to know information related to the fueling facility around the current vehicle position, and information related to the fueling facility around the destination far from the current vehicle position.

  The designation method may be a method of designating an area corresponding to the acquisition area by a municipality name or the like. Alternatively, a method may be used in which a map of the area corresponding to the acquisition area (map data in the map database 108) is specified by being displayed on the display device 140. That is, the user may specify the acquisition area by displaying a map of a desired area on the display device 140 by specifying a place name or scrolling the screen. In this case, the information output control unit 104 recognizes the area of the map displayed on the display device 140 as an acquisition area when receiving a request for displaying the gasoline price from the user, and informs the refueling facility in the acquisition area. The related data is requested to the center server 200 via the sales price information acquisition unit 110.

  The information output control unit 104 may determine the acquisition area based on the current vehicle position supplied from the vehicle position detection unit 102. In this case, the information output control unit 104 uses an area of a predetermined size centered on the own vehicle position as an acquisition area, and transmits data related to the fueling facility in the acquisition area via the sales price information acquisition unit 110 to the center server 200. To request.

  Alternatively, when the route guidance is being performed, the information output control unit 104 may determine the acquisition area based on the guidance route. In this case, the information output control unit 104 sells data related to the fueling facility around the guide route from the current vehicle position to the destination based on the current vehicle position supplied from the vehicle position detection unit 102. A request is made to the center server 200 via the price information acquisition unit 110. Note that the acquisition area designation / determination method may be selectable by the user.

  On the center side, when the above request is received from the vehicle side, the information management unit 204 of the center server 200 extracts the refueling facility information relating to the requested area from the data in the national version refueling facility database 206, It transmits to the in-vehicle information terminal 100 of the request source. At this time, the information management unit 204 of the center server 200 extracts the refueling facility information related to the refueling facility that is currently operating (within business hours) from the refueling facilities related to the requested area, and the request source It is good also as transmitting to the vehicle-mounted information terminal 100. Thereby, it is possible to prevent unnecessary transmission of the fueling facility information relating to the fueling facility outside the business hours. More preferably, the information management unit 204 of the center server 200 predicts the arrival time of the vehicle at each refueling facility, and sets the refueling facility that is predicted to be out of business hours upon arrival even within the current business hours. Such refueling facility information may not be transmitted to the requesting in-vehicle information terminal 100. Accordingly, it is possible to prevent unnecessary transmission of refueling facility information related to a refueling facility that is out of business hours upon arrival in consideration of the travel time of the vehicle, and the operation of an inexpensive refueling facility selected by the user The inconvenience of ending before arrival is prevented. The arrival time of the vehicle at each refueling facility may be the time when the vehicle enters the acquisition area to which each refueling facility belongs. Further, the information management unit 204 of the center server 200 predicts the required fuel amount to each refueling facility, and for the refueling facility information related to the refueling facility existing in the area that cannot be reached with the current fuel amount, the requesting vehicle It is good also as not transmitting to the information terminal 100. As a result, it is possible to prevent unnecessary transmission of refueling facility information relating to a refueling facility that cannot be reached with the current amount of fuel, and there is a disadvantage that the user selects a distant and inexpensive refueling facility and runs out of fuel. Is prevented.

  When the sales price information acquisition unit 110 receives the fueling facility information from the center server 200 (step 40), it updates the data in the fueling facility database 106 using the fueling facility information (step 50). Note that the sales price information acquisition unit 110 may notify the information output control unit 104 that acquisition of the requested fueling facility information from the center server 200 has been completed. The information output control unit 104 receives the request from the user in step 10 above, and until the sales price information acquisition unit 110 receives the fueling facility information from the center server 200 in step 40 above, for example, “ A message stating “Now downloading” may be displayed and output on the display device 140.

  The information output control unit 104 extracts the fueling facility information to be displayed from the fueling facility database 106 (step 60). The refueling facility information to be displayed may be refueling facility information of an area corresponding to the area of the map currently displayed on the display device 140, for example. Alternatively, the refueling facility information to be displayed may be refueling facility information relating to the area designated by the user in step 10 above. In this case, the fueling facility information to be displayed corresponds to the fueling facility information received from the center server 200. The information output control unit 104 may display and output a message indicating that “data processing is in progress” on the display device 140 from step 50 to step 70 described above.

  The information output control unit 104 sorts the fueling facility information extracted from the fueling facility database 106 in ascending order of the gasoline price (step 70). That is, the information output control unit 104 rearranges the list of refueling facilities in ascending order of gasoline prices based on the refueling facility information extracted from the refueling facility database 106. Further, the information output control unit 104 calculates an average value of gasoline prices based on the fueling facility information extracted from the fueling facility database 106. The average value of the gasoline price may be the average value of the refueling facilities to be displayed, or may be the average value of all the refueling facilities in the acquisition area. The average value of the gasoline price may be calculated on the center server 200 side and supplied from the center server 200 side together with the fueling facility information. In this case, the average value of the gasoline price may be an average value in a wider area, for example, an average price in the whole country or an average price in the area.

  The information output control unit 104 displays the fueling facility information extracted from the fueling facility database 106 together with the map (map data in the map database 108) on the display device 140 (step 80). In the present embodiment, on the display device 140, the fuel sales price and / or price ranking of each refueling facility and the position of each refueling facility are displayed. The location of each refueling facility may be displayed as a list of addresses, but may preferably be indicated by superimposing a predetermined refueling facility icon (graphic) on the location of each refueling facility on the map (FIG. 4).

  FIG. 4 shows an example of a display mode of the fueling facility information displayed on the display device 140. In the example shown in FIG. 4, an example of the display mode of the fueling facility information when the acquisition area and the fueling facility to be displayed are determined based on the current vehicle position is shown.

  In the example shown in FIG. 4, the position of each fueling facility is displayed on the map by a figure (fueling facility icon) in which the letter “G” is surrounded by a square. In this case, the fueling facility icon may be highlighted as compared with the icons of other facilities. Thereby, the position of the refueling facility where the refueling facility information is shown becomes clear.

  In the example shown in FIG. 4, the sales price of each refueling facility (in this example, the price of gasoline) is displayed in association with the refueling facility icon. Thereby, the user can grasp | ascertain the sales price and position of each fueling facility simultaneously. When a fueling facility is registered in the map database 108, the fueling facility icon related to the fueling facility may be drawn based on data in the map database 108. In the case of a new refueling facility that is not registered in the map database 108, the refueling facility icon of the refueling facility is newly generated using, for example, a given template, and is appropriately displayed on the map according to the location information of the refueling facility. It is displayed in a superimposed position. From the same point of view, the data related to the fueling facility in the map database 108 may be updated based on data sent from the center server 200 side, and new fueling facility information may be added as needed.

  Moreover, in the example shown in FIG. 4, the order of the price is displayed together with the sales price of each refueling facility. Thereby, the user can grasp at a glance which fueling facility is the cheapest. As shown in FIG. 4, the sales price ranking may be a ranking in the fueling facilities to be displayed, or may be a ranking in the fueling facilities in a wider area. In the latter case, the selling price of each refueling facility may be displayed so that the number among the number of refueling facilities is known. The order of sales prices of refueling facilities in a wider area may be calculated on the center server 200 side and supplied from the center server 200 side together with the refueling facility information. Further, the fueling facility icon related to the lowest priced fueling facility may be highlighted. Thereby, the user can grasp | ascertain the position of the cheapest fueling facility at a glance.

  Moreover, in the example shown in FIG. 4, the gasoline price of the area average is displayed with the sales price of each fueling facility. Thereby, the user can understand how the selling price of the fueling facility currently displayed is related to the market price in the surrounding area. Note that the average gasoline price in the district does not need to be displayed in association with the refueling facility icon, and in order to minimize the area of the map hidden behind the display of the refueling facility information, avoid duplication in one place. May be displayed. Further, from the same viewpoint, the display of the fueling facility information as shown in FIG. 4 may be displayed only for the fueling facility icon selected by the user. The selection of the fueling facility icon may be realized by a touch operation on the touch panel. Further, from the same viewpoint, for example, detailed information such as business hours, telephone numbers, and the presence / absence of self-service may be displayed only for the fueling facility icon selected by the user.

  As described above, according to the present embodiment, the location of each refueling facility is displayed together with the selling price of each refueling facility, so the user can select a desired refueling facility by taking both the location and price into consideration. Can do. For example, in the example shown in FIG. 4, if the user wants a relatively cheaper refueling facility in the vicinity rather than the cheapest refueling facility, compare not in the cheapest refueling facility C but in the vicinity. A cheaper refueling facility A would be selected. Alternatively, the user may select refueling at the refueling facility B because the refueling facility B is on the future route and is cheaper than the refueling facility A. On the other hand, even if it takes some time, a user who desires the cheapest fueling facility will select the cheapest fueling facility C that is not on the route.

  In addition, according to the present embodiment, since the order is displayed together with the sales price of each refueling facility, the user does not have to compare the sales prices of many refueling facilities one by one. The order of sales prices can be grasped. For example, in the example shown in FIG. 4, since there are three refueling facilities, the ranking among them can be grasped relatively easily, but in reality, more refueling facilities may be displayed. This is particularly effective when information on a large number (for example, five or more) of refueling facilities is displayed.

  In addition, according to the present embodiment, since the average value of the sales prices of the surrounding fueling facilities is displayed together with the selling price of each fueling facility, the user can select a desired fueling facility in consideration of the market price. it can. For example, as in the example shown in FIG. 4, since the average gasoline price in the district is 125 yen, the user can determine that the fueling facilities A and B displayed are sufficiently cheaper than the surroundings. .

  In addition, according to the present embodiment, since the information of the refueling facility that is outside the business hours in relation to the current time is not displayed, the user does not unintentionally go to the refueling facility outside the business hours. Can give you a sense of security. From the same viewpoint, the acquisition time (reliability) of the information may be displayed together with the sales price of each refueling facility. This is because the sales price can change dynamically, and the user can grasp that the reliability is low if, for example, the displayed sales price is yesterday's information. Thereby, the distrust of the user which can be given when the displayed sales price is different from the actual sales price can be prevented.

  In the description related to FIG. 3 and FIG. 4, the fuel is related to gasoline. However, the present invention can be similarly applied when the fuel is high-octane or light oil. Further, the type of fuel for which the price is displayed may be designated by the user. Alternatively, when the type of fuel to be used is specified by the vehicle, the price may be displayed only for the specified fuel.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the center server 200 collects fueling facility information from each fueling facility operator terminal 300 and supplies it to each in-vehicle information terminal 100, but the fueling facility information from each fueling facility operator terminal 300. Can be directly supplied to each in-vehicle information terminal 100. Moreover, the fueling facility information supplied from the center server 200 may be transmitted to a plurality of vehicles via communication between the in-vehicle information terminals 100 (so-called inter-vehicle communication).

  In the above-described embodiment, the sales price information acquisition unit 110 acquires data from the center server 200 when a request from the user is input. However, the present invention is not limited to this. No. For example, the sales price information acquisition unit 110 may acquire data from the center server 200 and update the data in the fueling facility database 106 when the ignition switch is turned on. In this case, since the data in the fueling facility database 106 is updated in advance before the request from the user is input, the fueling facility information can be displayed and output with excellent responsiveness.

  Moreover, in the above-mentioned Example, the sales price information acquisition part 110 of the vehicle-mounted information terminal 100 may acquire only the sales price information which can change dynamically from the center server 200 among fueling facility information. In this case, the sales price information acquisition unit 110 may acquire other fueling facility information from the center server 200 periodically (for example, every month) and update the data in the fueling facility database 106. Thereby, it is possible to reduce the amount of communication data between the in-vehicle information terminal 100 and the center server 200 required for one sales price display.

  In the above-described embodiment, when the number of refueling facilities to be displayed is large, sales price information on the top five refueling facilities with the lowest sales prices is displayed on the map in order to avoid complicated display. It is good to do. In this case, the refueling facility icons of the top five refueling facilities may be highlighted so as to be easily distinguishable from the refueling facility icons of other refueling facilities. Also in this case, when the user selects a fueling facility icon of another fueling facility, information on the fueling facility may be output.

  In the above-described embodiment, in order to reduce the amount of communication data between the in-vehicle information terminal 100 and the center server 200, the information management unit 204 of the center server 200 is currently in business (within business hours). ) Although the fueling facility information related to the fueling facility is extracted and transmitted to the requesting vehicle-mounted information terminal 100, even if the fueling facility information related to all the fueling facilities outside business hours is transmitted to the vehicle-mounted information terminal 100 Good. In this case, filtering may be performed on the in-vehicle information terminal 100 side so as not to display the refueling facility information related to the refueling facility outside business hours. Similarly, on the vehicle-mounted information terminal 100 side, the arrival time of the vehicle to each refueling facility is predicted, and the refueling facility information related to the refueling facility that is predicted to be out of business hours when arriving even within the current business hours. , Do not display. Further, the in-vehicle information terminal 100 side predicts the required fuel amount to each refueling facility, and does not display the refueling facility information relating to the refueling facility existing in the area that cannot be reached with the current fuel amount. .
