Sex can be judged.

  A fuel efficiency information processing system 1000 according to the present embodiment will be described with reference to the drawings. FIG. 1 is a diagram showing an overall outline of a fuel efficiency information processing system 1000.

  The fuel efficiency information processing system 1000 according to the present embodiment includes an in-vehicle device 2000 mounted on a vehicle and a server 3000 that can communicate with the in-vehicle device 2000.

  As shown in FIG. 1, the in-vehicle device 2000 includes a fuel efficiency information presentation device 100, a communication terminal 200 that communicates with the outside, a map database (map DB) 300 having map information, and a GPS (Global Positioning System) 410. And a navigation device 400 that detects a current position and searches for a route to a destination, and a vehicle controller 500 that acquires information about the vehicle.

  The fuel efficiency information presentation device 100 is configured by combining operation circuits such as a CPU, MPU, DSP, and FPGA. The communication terminal 200 communicates with the server 3000 using a mobile phone network, UWB, DSRC, wireless LAN, or the like. The map database 300 uses a recording medium such as an HDD, CD, MD, DVD, or optical disk, and accepts access (reading) of the fuel efficiency information presentation device 100 and the navigation device 400.

  As shown in the figure, the server 3000 includes a fuel efficiency information management device 10, a data storage device 20 for storing information collected from the vehicle (on-vehicle device 2000), and a server-side map database (map DB) having map information. 30, a distribution device 40 that distributes information to the outside, and a communication device 50 that communicates with the outside including the vehicle.

  The fuel consumption information management device 10 is configured by combining operation circuits such as a CPU, MPU, DSP, and FPGA. The data storage device 20 is composed of a RAM or the like. Further, the server-side map database 30 uses a recording medium such as HDD, CD, MD, DVD, optical disk, etc., as in the vehicle side. The communication network of the communication unit 50 is a mobile phone network, UWB, DSRC, wireless LAN, or the like.

  The in-vehicle device 2000 and the server 3000 exchange information with each other via the communication terminal 200 and the communication unit 50.

  FIG. 2 is a diagram showing a block configuration of the fuel efficiency information processing system 1000. Hereinafter, each configuration of the fuel consumption information management device 10 on the server 3000 side and each configuration of the fuel consumption information presentation device 100 on the in-vehicle device 2000 side will be described based on FIG. 2.

  First, the fuel consumption information management device 10 will be described. As shown in FIG. 2, the fuel efficiency information management device 10 includes a fuel efficiency information aggregation unit 11 and a statistical processing unit 12.

  The fuel consumption information aggregating unit 11 collects fuel consumption information when the vehicle travels from the in-vehicle device 2000 mounted on each vehicle via the communication terminal 200 and the communication device 50. In the present embodiment, the collected information is stored in the data storage device 20, but may be stored in the memory 1211 on the in-vehicle device 2000 side.

  The aggregated fuel efficiency information includes the fuel efficiency and the position information of the travel point when the fuel efficiency is detected. The fuel consumption is the amount of fuel consumed by driving the vehicle (fuel consumption). This is the travel distance per liter of fuel divided by the travel distance or the fuel consumption per kilometer of travel distance divided by the travel distance. Note that the amount of fuel consumed by traveling of the vehicle (fuel consumption) may be expressed as the amount of carbon dioxide emitted during traveling.

  The position information included in the fuel consumption information is information that can specify latitude / longitude information, map coordinates, intersection name, facility name, and other travel points. The fuel consumption Y when a certain vehicle travels the point A can be obtained by the fuel consumption information collected by the fuel consumption information collecting unit 11. Then, by collecting a large amount of fuel consumption information, it is possible to obtain fuel consumption distributions when traveling at points A, B, C.

  Next, the statistical processing unit 12 will be described. The statistical processing unit 12 refers to the map information 31 in which the fuel consumption factors that affect the fuel consumption of the vehicle are mapped, and generates the fuel consumption statistics in which the aggregated fuel consumption information is statistics for each fuel consumption factor. Specifically, the statistical processing unit 12 refers to the map information 31 to which the fuel consumption factor is mapped based on the position information included in the fuel consumption information obtained from the vehicle, associates the fuel consumption factor with the fuel consumption information, and Statistics of fuel consumption are taken for each.

  The fuel economy factors used in the statistics are road or link identifiers, road or link slope, road or link elevation, road or link curvature, road or link traffic lights, road or link pause points, Information including 1 or 2 or more that affects fuel consumption such as presence or absence of road or link deceleration zone, other road attributes, vehicle type, vehicle type, displacement and other vehicle information, or congestion level, speed, traffic regulation and other traffic conditions is there.

  FIG. 3 shows an example of the fuel consumption factor. As shown in FIG. 3, fuel efficiency factors subdivided according to the fuel consumption increase / decrease effect can be defined. For example, the fuel efficiency factors related to the road gradient are the road gradient that forms the uphill, the road gradient that forms the downhill, the road slope rate of the predetermined value range that forms the steep uphill, and the gentle uphill. It can be defined by subdividing the slope ratio of the road in the predetermined value range. The same applies to other road attributes.

  As for the vehicle information, further subdivided fuel efficiency factors can be defined. As shown in FIG. 3, one vehicle type may be defined as a fuel consumption factor, and a plurality of grouped vehicle types may be defined as a fuel consumption factor. Similarly, the contents of the fuel consumption factor can be defined in advance for the vehicle type and the displacement.

  In addition, more detailed fuel consumption factors can be defined for traffic conditions. For example, the degree of traffic congestion may be quantitatively expressed by the traveling speed of a predetermined link and the required travel time of a predetermined section, and may be defined for each level. The traffic regulation may be defined as a fuel consumption factor for each traffic regulation and the contents of the traffic regulation.

  The statistical processing unit 12 statistics fuel consumption information for each predefined fuel consumption factor. For example, the statistical processing unit 12 investigates the distribution of fuel consumption information aggregated for each fuel consumption factor.

  FIG. 4 shows an example of the distribution of fuel consumption statistics for each fuel consumption factor (link W) specified by the link ID. As described above, since the fuel consumption factor can be specified by combining a plurality of factors, the statistical processing unit 12 determines the fuel consumption distribution for each link W of the vehicle having the displacement of 3000 class and the uphill of the vehicle of the vehicle types X to Y. Statistical processing such as distribution for each road can be performed. The statistical processing unit 12 stores the statistical result in the data storage device 20 or the statistical storage unit 121 in the statistical processing unit 12.

  The statistical processing unit 12 includes a statistical transmission unit 122. The statistics sending unit 122 sends the fuel consumption statistics to the fuel consumption information presentation device 100 in accordance with a predetermined timing or a request on the in-vehicle device 2000 side. The statistics sending unit 122 sends to the fuel consumption information presentation device 100 fuel consumption statistics about a predefined fuel consumption factor or fuel consumption statistics about the fuel consumption factor requested by the fuel consumption information presentation device 100. The sent fuel consumption statistics are received by the in-vehicle transmission / reception unit 110 of the fuel consumption information presentation device 100 and stored in the statistics storage unit 111 in the in-vehicle transmission / reception unit 110.

  Next, the fuel consumption information presentation device 100 mounted on the vehicle will be described. As shown in FIG. 2, the fuel efficiency information presentation device 100 includes an in-vehicle transmission / reception unit 110, a fuel efficiency information collection unit 120, a fuel efficiency calculation unit 130, an evaluation unit 140, a fuel efficiency estimation unit 150, a route search unit 160, A fuel consumption information display unit 170.

  The in-vehicle transmission / reception unit 110 according to the present embodiment exchanges information with the fuel consumption information management device 10 on the server 3000 side via the communication terminal 200. The in-vehicle transmission / reception unit 110 receives the fuel consumption statistics generated by the statistical processing unit 12 of the fuel consumption information management device 10 and stores the fuel consumption statistics in the statistics storage unit 111. Further, the in-vehicle transmission / reception unit 110 sends the fuel efficiency information including the position information acquired by the in-vehicle apparatus 2000 side of the host vehicle to the fuel efficiency information management apparatus 10. The in-vehicle transmission / reception unit 110 sends fuel efficiency factors (road attributes, vehicle information, traffic conditions) and other probe information to the fuel efficiency information management apparatus 10 in addition to the fuel efficiency information.

  In addition, the fuel consumption information collection unit 120 collects fuel consumption information when the host vehicle is traveling. As described above, the fuel efficiency information includes the fuel efficiency and the position information of the travel point when the fuel efficiency is detected. This position information is information that can specify latitude and longitude information, map coordinates, intersection names, facility names, and other travel points. Fuel consumption information collected during traveling is stored in the memory 1211. The accumulated fuel consumption information may include a fuel consumption factor corresponding to the position information. In that case, the fuel consumption information collection unit 120 refers to the map information 301 to which the fuel consumption factor is mapped, searches for the fuel consumption factor corresponding to the travel position of the fuel consumption information, and stores it in the memory 1211 in association with the fuel consumption information. The fuel consumption information collecting unit 120 can also collect and accumulate probe information related to traffic such as speed information and link travel time in addition to the fuel consumption information.

  Further, the fuel consumption calculation unit 130 refers to the map information 301 on which the fuel consumption factors affecting the increase or decrease in the vehicle fuel consumption are mapped based on the fuel consumption information collected by the fuel consumption information collection unit 120, and the fuel consumption factors of the host vehicle Fuel consumption information for each is calculated. That is, the fuel consumption calculation unit 130 calculates the actual fuel consumption information of the host vehicle under a predetermined fuel consumption factor based on the traveling experience of the host vehicle with respect to the host vehicle on which it is mounted. That is, the vehicle type, the vehicle type, and the displacement specific to the host vehicle are determined under predetermined fuel efficiency factors (passing through a predetermined travel link, under predetermined conditions such as weather during travel, travel time, and weather during travel) Fuel consumption information at a predetermined slope, etc.). Although the calculation method of fuel consumption information is not particularly limited, the fuel consumption calculation unit 130 takes fuel consumption statistics for each predetermined fuel consumption factor, calculates a representative value such as an average value, a median value, a maximum value, and a mode value, The value is used as fuel consumption information for each fuel consumption factor of the vehicle. If there is no disadvantage (accumulation of storage area, increase in communication fee) in accumulating all of the collected fuel consumption information on the fuel consumption information presentation device 100 side, the collected fuel consumption information is not obtained without obtaining a representative value. All of the information may be stored in the memory 1211.

  And the evaluation part 140 has the fuel consumption statistics acquisition part 141 and the fuel consumption evaluation part 142, the fuel consumption information for every fuel consumption factor of the own vehicle calculated by the fuel consumption calculation means 130, and the statistics on the fuel consumption information management apparatus 10 side In comparison with the fuel consumption statistics for each fuel consumption factor generated by the processing unit 12, the degree of dispersion of the fuel consumption information of the vehicle with respect to the fuel consumption statistics is evaluated.

  First, the fuel consumption statistics acquisition unit 141 acquires the fuel consumption statistics as shown in FIG. The fuel consumption statistics acquisition unit 141 acquires the fuel consumption statistics about the fuel consumption factors common to the fuel consumption factors of the fuel consumption information of the host vehicle calculated by the fuel consumption calculation unit 130. The fuel consumption statistics acquisition unit 141 may request the fuel consumption information management device 10 to acquire the fuel consumption statistics required at the time of evaluation, or may select and acquire the required fuel consumption statistics from the previously stored fuel consumption statistics. Good.

  Subsequently, the fuel consumption evaluation unit 142 compares the fuel consumption information calculated by the fuel consumption calculation unit 130 with the fuel consumption statistics acquired by the fuel consumption statistics acquisition unit 141 and evaluates the degree of dispersion of the fuel consumption information of the vehicle with respect to the fuel consumption statistics. . This is because the fuel efficiency statistics calculated based on the fuel efficiency information of an unspecified number of vehicles and the fuel efficiency information of the own vehicle detected in the specific vehicle performance and the specific environment usually show different values (trends). The degree of dispersion is obtained as a value indicating the positioning of the fuel efficiency information unique to the host vehicle with respect to the fuel efficiency statistics of an unspecified number of vehicles. The method for calculating the degree of dispersion is not particularly limited, and the amount of deviation or other deviation from the representative value such as the mode value or median value of the fuel economy statistics can be used as the degree of dispersion. For example, when the fuel consumption statistics acquisition unit 141 acquires “statistics of fuel consumption information of a vehicle traveling on an uphill in the inclination rate band B” shown in FIG. As shown in FIG. 4, the obtained fuel consumption statistics are compared with the “fuel consumption information of the vehicle traveling on the uphill in the slope rate band B” calculated by the fuel consumption calculation unit 130, and the difference from the mode value of the fuel consumption statistics a is evaluated as the degree of dispersion of the fuel consumption information of the vehicle relative to the fuel consumption statistics. By this evaluation, the position of the fuel consumption information of the own vehicle with respect to the fuel consumption statistics obtained for the plurality of vehicles by the fuel consumption information management device 10 can be obtained quantitatively.

  Next, the fuel consumption estimation unit 150 will be described. The fuel consumption estimation unit 150 acquires the fuel consumption statistics regarding the fuel consumption factors of the route to the input destination, and estimates the fuel consumption information of the route based on the fuel consumption statistics and the degree of dispersion evaluated by the evaluation unit. The navigation device 400 receives an input of a destination and searches for one or more routes from the current position (departure point) to the destination. The fuel consumption estimation unit 150 refers to the map information on which the fuel consumption factor is mapped, and extracts the fuel consumption factor of the route (candidate) searched by the navigation device 400 or the fuel consumption factor included in the route (candidate). Then, the fuel consumption estimation unit 150 acquires the fuel consumption statistics related to each extracted fuel consumption factor, and based on the fuel consumption statistics related to each fuel consumption factor and the variance of the fuel consumption information of the host vehicle obtained by the evaluation unit 140, The fuel consumption under the factor is calculated, the fuel consumption under each fuel consumption factor is totaled for each route, and the fuel consumption information for each route is estimated.

  For example, when the route Y to the destination includes an uphill in the slope zone C and a sharp curve in the curvature zone O, the fuel consumption estimation unit 150 travels on the uphill in the slope zone C shown in FIG. The vehicle fuel consumption statistics and the variance a of the host vehicle obtained by the evaluation unit 140 are acquired, and a value R that is separated from the mode value of the fuel consumption statistics by the variance a is estimated as the fuel consumption information of the host vehicle. Similar processing is executed for the fuel consumption factor of the curvature band O. Then, the fuel consumption information for each of the obtained fuel consumption factors (uphill in the slope zone C, sharp curve in the curvature zone O) is summed, and the fuel consumption information on the route Y is estimated. Similarly, fuel consumption information is estimated for all routes (other than route Y) to the destination.

  Of course, it is possible to calculate the fuel consumption information of the host vehicle when traveling on the route Y by using the fuel consumption statistics for the route Y (links constituting the route Y). When there is a route composed of links W1 to W5 as shown in FIG. 7, the fuel consumption estimation unit 150 acquires the fuel consumption statistics of each link W1 to W5, and uses the degree of dispersion a of the fuel consumption information of the host vehicle, The fuel consumption information R1 to R5 of each link is estimated. And fuel consumption information R1-R5 is added and the fuel information of the path | route from a departure place (Start) to the destination (Goal) is estimated.

  In addition, the fuel consumption estimation unit 150 uses the fuel consumption statistics for each link using the fuel consumption statistics for each link, such as the road gradient, altitude, curvature, and presence / absence of signals, without using the fuel consumption statistics of the links W1 to W5. Fuel consumption information can also be estimated. In addition, what is necessary is just to add the fuel consumption information estimated for every fuel consumption factor, when each link contains a several fuel consumption factor.

  In this way, in order to evaluate the degree of dispersion of the fuel consumption information of the vehicle relative to the fuel consumption statistics in advance for a predetermined fuel consumption factor (positioning with respect to the fuel consumption statistics), for the route where the vehicle has never actually traveled, The fuel consumption information of the host vehicle can be calculated using the fuel consumption statistics of the route. That is, even if the host vehicle has never traveled, the fuel efficiency information in consideration of conditions unique to the host vehicle can be calculated using the fuel efficiency information when the other vehicle has traveled.

  Furthermore, the route search unit 160 searches for a route using fuel consumption as an index based on the estimated fuel consumption information of each route. The route search unit 160 of the present embodiment performs a search that gives priority to a route with a small amount of fuel consumption (or carbon dioxide emission). The route search unit 160 searches for route candidates based on any one or more of a required time, a required fee, a travel distance, and a travel road type in addition to the fuel consumption. This is because the user selects a route in consideration of indices other than fuel consumption. Incidentally, a route searched based on an index other than fuel efficiency is displayed by a fuel efficiency information display unit 170 described later. The selected route information is output in accordance with a selection command for selecting one route input by the user.

  Next, the fuel information display unit 170 will be described. The fuel information display unit 170 includes an editing unit 171, a selection receiving unit 172, and an output unit 173. The fuel information display unit 170 includes a route searched by the route search unit 160, fuel consumption information estimated for the route, and the route. The information including the fuel efficiency factor to be displayed and the influence of the fuel efficiency factor on the fuel efficiency is displayed.

  The editing unit 171 edits the display information in which the route searched by the route searching unit 160, the fuel efficiency factor of the route, and the influence of the fuel efficiency factor on the fuel efficiency are associated with each other. Although the display mode is not particularly limited, the editing unit 171 of the present embodiment edits display information that displays the fuel efficiency factor and the influence of the fuel efficiency factor on the fuel efficiency along the route. The display position of the fuel consumption factor is preferably displayed at a position corresponding to the positional relationship between the actual position of the fuel consumption factor and the route.

  In this way, by displaying the route, fuel efficiency factor, and their impact in association with each other, it is possible to determine the total amount of fuel efficiency factor that exists and what effect (increase or decrease in fuel efficiency) on the route. Can be recognized at a glance. By visually recognizing the route, the fuel consumption factor, and the information associated with the influence of the fuel consumption factor, the user can understand the breakdown of the fuel consumption of the searched route and make a reasonable judgment on the fuel consumption for each route. In addition, since the position of the fuel consumption factor on the route and its influence can be comprehensively recognized, a new route avoiding the fuel consumption factor that increases the fuel consumption can be searched. Furthermore, in addition to the fuel consumption information of the entire route (candidate), the breakdown of the fuel consumption information of each route (candidate) can be shown in detail, so after narrowing down to one route after examining the breakdown of fuel information It is possible to search for other routes and output route guidance that satisfies the requirements.

  In addition, when the fuel consumption factor is displayed together with the route, the editing unit 171 edits display information for displaying a factor display image associated with the content of each fuel consumption factor in advance, and displays the influence of the fuel consumption factor on the fuel consumption. In this case, the display information for displaying the influence display image associated in advance with the content of the influence on the fuel consumption is edited. An example of the factor display image and the influence display image is shown in FIG. The factor display image is not particularly limited and can be arbitrarily defined as long as it is an image reminiscent of the fuel consumption factor. Similarly, the influence display image can be associated with the content of the influence of the fuel consumption factor on the fuel consumption, but can be arbitrarily defined as long as it is an image. Further, the display size of the influence display image may be changed according to the contents of the influence.

  In addition, when the fuel efficiency factor deteriorates the fuel efficiency, the editing unit 171 indicates the fuel efficiency factor and / or the influence of the fuel efficiency factor on the fuel efficiency in warm colors including red, and the fuel efficiency factor improves the fuel efficiency. Edits display information for displaying the fuel efficiency factor and / or the influence of the fuel efficiency factor on the fuel efficiency in a cool color including blue. For this reason, in this embodiment, as shown in FIG. 8, the display color of a fuel consumption factor (a factor display image is included) and / or fuel consumption information (an influence display image is included) is defined beforehand.

  An example of the display information edited by the editing unit 171 is shown in FIG. As shown in FIG. 9, along with the route from the departure point to the destination, the fuel consumption factors (uphill, high degree of traffic jam, downhill) existing on the route are displayed in the factor display image. The factor display image is displayed at a position corresponding to the position where the fuel consumption factor exists. Further, an influence display image indicating the influence is displayed together with the factor display image. That is, on the displayed route, a position with an uphill is displayed as a factor display image, and an effect display image displays that the fuel consumption is increased due to the uphill.

  Note that the degree of traffic congestion, traveling speed, time required for passing, etc. occur in a predetermined range of the route, so that the degree of traffic congestion is displayed by changing the color of the route or blinking the route. That is, the editing unit 171 displays the traffic information (congested section, congested section, smooth running section) acquired from the outside superimposed on the searched route. The degree of traffic congestion, traveling speed, time required for passing, etc. are obtained from VICS (Vehicle Information and Communication System).

  As shown in FIG. 9, the editing unit 171 includes, in the display information, the fuel consumption amount and the fuel fee of the entire route, in which the fuel consumption amount of each link is integrated. Further, the editing unit 171 calculates the fuel consumption of each link * the fuel consumption of each link obtained from the link length, the total fuel consumption of the route obtained by integrating the fuel fuel consumption of each link, the total fuel consumption of the route / The average fuel and the like of the route determined by the route distance can be included in the display information.

  Thus, by displaying the presence and location of the fuel consumption factor and the influence of the fuel consumption factor on the fuel consumption together with the route, the breakdown of the fuel consumption information up to the destination can be viewed at a glance.

  In addition, the editing unit 171 edits display information displayed when one of the routes searched by the route searching unit 160 is selected. For the selected route, the editing unit 171 edits the display information in which the fuel efficiency factor of the route and the influence of the fuel efficiency factor on the fuel efficiency are associated with each other. The display mode is not particularly limited. The fuel consumption factor and its influence are grayed out in advance, and when the route is selected with a cursor or touch panel, the grayout is removed and the fuel consumption factor and its influence are displayed. You may do it. As an example of the display mode, as shown in FIG. 9, when there are a route represented by a solid line and a route represented by a dotted line, the editing unit 171 displays the route selected by the user (with the cursor applied). Display information indicating the table fuel efficiency factor and the influence of the fuel efficiency factor is edited only for the selected route or the route selected by input to the touch panel. Thus, detailed fuel consumption information can be provided only for the route for which the user wants information. Note that the editing unit 171 may edit the display information that displays the route, the fuel efficiency factor of the route, and the influence of the fuel efficiency factor on the fuel efficiency in association with the route other than the selected route. These display modes are preferably switchable by user input.

  Further, as shown in FIG. 10, the editing unit 171 can edit display information that displays the content of the fuel consumption factor and the fuel consumption when the fuel consumption factor passes as text information.

  Further, the editing unit 171 edits display information that displays fuel consumption information by the amount of carbon dioxide emission. For example, as shown in FIG. 10, the carbon dioxide emission amount can be displayed together with the fuel consumption. The amount of carbon dioxide emission may be indicated by a number or may be displayed as an image showing the magnitude.

  In addition, the editing unit 171 displays the fuel efficiency factor for each route and the effect of the fuel efficiency factor on the fuel efficiency in a region different from the region where the route searched by the route search unit 160 is displayed. Edit the display information. An example of display information such as fuel efficiency factors that do not include a route (map information) is shown in FIG. As shown in FIG. 11, the editing unit 171 edits display information including an influence display image indicating the influence of the fuel efficiency factor on the fuel efficiency as well as indicating the upward and downward slopes of the routes 1 to 3. Further, the editing unit 171 includes the required time for each of the routes 1 to 3, the toll road fee, the fuel consumption amount, and the fuel fee in the display information.

  The selection receiving unit 172 receives a route selection command from the user. The output unit 173 outputs the route selected via the selection receiving unit 172.

  The monitor 1731 displays the display information illustrated in FIGS. 9 to 11 on the screen.

  Note that the fuel efficiency factor and the influence of the fuel efficiency factor may be output by voice together with the position of the fuel efficiency factor. In this case, the editing unit 171 edits text information in which the position of the fuel efficiency factor and the influence thereof are known, such as “the fuel economy is reduced at the crossing of XX station”.

  Next, the control procedure of the information processing system 1000 of this embodiment will be described. FIG. 12 is a flowchart for explaining control procedures of the fuel consumption information presentation devices 100-1, 100-2, 100-n and the fuel consumption information management device 10 of the information processing system 1000.

  First, the fuel consumption information collection unit 120 of the fuel information presentation device 100 detects the fuel consumption information of the host vehicle (S101). The fuel consumption information collection unit 120 refers to the map information on which the predefined fuel consumption factors are mapped (S102), and associates the fuel consumption information with the fuel consumption factors and stores them in the memory 1211 (S103). The in-vehicle transmission / reception unit 110 sends the collected fuel efficiency information to the fuel efficiency information management apparatus 10 at a predetermined timing (S104). The timing of sending is not particularly limited, and the fuel consumption information (probe information) collected when an operation using the communication function is performed or collected at a predetermined cycle is sent.

  Furthermore, the fuel consumption calculation unit 130 calculates fuel consumption information for each fuel consumption factor of the host vehicle based on the collected fuel consumption information of the host vehicle (S105). The calculation of the fuel consumption information of the host vehicle may be executed at a predetermined cycle, or may be executed at a timing when the fuel consumption information regarding the fuel consumption factor is newly acquired.

  The fuel consumption information collection unit 11 of the fuel consumption information management device 10 on the server 3000 side collects the fuel consumption information sent from the in-vehicle transmission / reception unit 110 mounted on an unspecified number of vehicles (probe vehicles) (S120). Then, the statistical processing unit 12 generates fuel consumption statistics in which the aggregated fuel consumption information is statistically calculated for each fuel consumption factor (S121). The generated fuel consumption statistics are stored in the statistics storage unit 121. The collection of information on the probe vehicle (on-vehicle device 2000), the aggregation of information on the server 3000, and the statistical processing are repeated at a predetermined timing.

  The fuel consumption information presentation device 100 starts the fuel consumption information presentation process triggered by the input of the destination from the user (S106). The destination may be directly input to the fuel efficiency information presentation device 100 or may be input via the navigation device 400 connected by the in-vehicle LAN.

  The evaluation unit 140 requests the fuel information management apparatus 10 for fuel consumption statistics regarding the fuel consumption factor for which the fuel consumption of the host vehicle has been calculated (S108). The method for specifying the fuel consumption factor of the required fuel consumption statistics is not particularly limited, and may be a fuel consumption factor for the latest fuel consumption information, or may be a fuel consumption factor having the largest collection amount of fuel consumption information.

  In response to this request, the statistics sending unit 122 of the fuel consumption information management unit 10 sends the fuel consumption statistics regarding the fuel consumption factor related to the request to the fuel consumption information presentation device 100 (S123).

  The fuel statistics acquisition unit 141 of the evaluation unit 140 acquires fuel consumption statistics related to the request. Then, the fuel consumption evaluation unit 142 compares the fuel consumption information of the own vehicle calculated in S105 with the fuel consumption statistics, and evaluates the degree of dispersion of the fuel consumption information of the own vehicle with respect to the fuel consumption statistics (S108). The fuel consumption evaluation unit 142 obtains the difference from the representative value (average value, median value, mode value, etc.) of the fuel consumption statistics as the degree of dispersion.
