また同図に示すように、サーバ3000は、燃費情報管理装置10と、車両(車載装置2000)から集めた情報を記憶するデータ保存装置20と、地図情報を有するサーバ側地図データベース(地図DB)30と、外部へ情報を配信する配信装置40と、車両を含む外部との通信を行う通信装置50とを有する。   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.

これら車載装置2000とサーバ3000とは、通信端末200と通信部50を介して相互に情報の授受を行う。   The in-vehicle device 2000 and the server 3000 exchange information with each other via the communication terminal 200 and the communication unit 50.

図2は、燃費情報処理システム1000のブロック構成を示す図である。以下、図2に基づいて、サーバ3000側の燃費情報管理装置10の各構成、及び車載装置2000側の燃費情報提示装置100の各構成について説明する。   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.

まず、燃費情報管理装置10について説明する。図2に示すように、燃費情報管理装置10は、燃費情報集約部11と、統計処理部12とを有する。   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.

この燃費情報集約部11は、通信端末200及び通信装置50を介して、車両が走行する際の燃費情報を、各車両に搭載された車載装置2000から集約する。本実施形態において、集約された情報はデータ保存装置20に蓄積されるが、これを車載装置2000側のメモリ1211に保存してもよい。   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.

集約される燃費情報は、燃費と、その燃費が検出された際の走行地点の位置情報を含む。燃費は、車両の走行によって消費される燃料の量(燃料消費量)である。走行距離を燃料消費量で割った燃料1リットルあたりの走行距離又は燃料消費量を走行距離で割った走行距離1kmあたりの燃料消費量である。なお、車両の走行によって消費される燃料の量(燃料消費量)を、走行時に排出される二酸化炭素の量で表現してもよい。   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.

また、燃費情報に含まれる位置情報は、緯度経度情報、地図座標、交差点名、施設名その他の走行地点を特定できる情報である。燃費情報集約部11が集約するこの燃費情報により、ある車両が地点Aを走行する際の燃費Yを得ることができる。そして、燃費情報を多数集約することにより、地点A、B、C…を走行する際の燃費の分布をそれぞれ得ることができる。   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.

次に統計処理部12について説明する。統計処理部12は、車両の燃費に影響を与える燃費要因がマッピングされた地図情報31を参照し、集約された燃費情報が燃費要因ごとに統計された燃費統計を生成する。具体的に、統計処理部12は、車両から得た燃費情報に含まれる位置情報に基づいて、燃費要因がマッピングされた地図情報31を参照し、燃費要因と燃費情報とを対応づけ、燃費要因ごとに燃費情報を統計する。   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.

統計に用いられる燃費要因は、道路又はリンクの識別子、道路又はリンクの勾配、道路又はリンクの標高、道路又はリンクの曲率、道路又はリンクの信号機の有無、道路又はリンクの一時停止ポイントの有無、道路又はリンクの減速ゾーンの有無その他の道路属性、車種、車型、排気量その他の車両情報、又は渋滞度、速度、交通規制その他の交通状態などの燃費に影響を与える1又は2以上含む情報である。   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.

図3に燃費要因の一例を示す。図3に示すように、燃費の増減効果に応じて細分化された燃費要因を定義することもできる。たとえば、道路の勾配に関する燃費要因を、上り坂を形成する道路の勾配、下り坂を形成する道路の勾配、急な上り坂を形成する所定値帯の道路傾斜率、緩やかな上り坂を形成する所定値帯の道路の傾斜率と細分化して定義することができる。他の道路属性においても同様である。   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.

車両情報についても、さらに細分化された燃費要因を定義することができる。図3に示すように、一の車種を燃費要因としてもよいし、複数のグループ化された車種を燃費要因と定義してもよい。車型や排気量についても同様に、予め燃費要因の内容を定義することができる。   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.

また、交通状態についても、さらに細分化された燃費要因を定義することができる。たとえば、渋滞度を、所定リンクの走行速度、所定区間の通過所要時間により定量的に表現し、それをレベルごとに定義してもよい。交通規制を、交通規制の有無、交通規制の内容ごとに燃費要因として定義してもよい。   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.

統計処理部12は、予め定義された燃費要因ごとに燃費情報を統計する。たとえば、統計処理部12は、燃費要因ごとに集約された燃費情報の分布を調査する。   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.

図4に、リンクIDにより特定される燃費要因(リンクW)ごとに統計された燃費の分布の一例を示す。先述したように、燃費要因は、複数の要因を組み合わせて特定できることから、統計処理部12は排気量が3000クラスの車両のリンクWごとの燃費の分布、車種X〜Yの車両の上り坂を含む道路ごとの分布といった統計処理を行うことができる。統計処理部12は、統計結果をデータ保存装置20又は統計処理部12内の統計記憶部121に記憶する。   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.

また、統計処理部12は統計送出部122を備える。この統計送出部122は、所定のタイミング又は車載装置2000側の要求に応じて、燃費統計を燃費情報提示装置100へ送出する。統計送出部122は、予め定義された燃費要因についての燃費統計又は燃費情報提示装置100が要求する燃費要因についての燃費統計を、燃費情報提示装置100へ送出する。送出された燃費統計は、燃費情報提示装置100の車載送受信部110により受信され、車載送受信部110内の統計記憶部111に記憶される。   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.

続いて、車両に搭載された、燃費情報提示装置100について説明する。図2に示すように、燃費情報提示装置100は、車載送受信部110と、燃費情報収集部120と、燃費算出部130と、評価部140と、燃費推測部150と、経路探索部160と、燃費情報表示部170とを備える。   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.

本実施形態の車載送受信部110は、通信端末200を介してサーバ3000側の燃費情報管理装置10と情報の授受を行う。車載送受信部110は、燃費情報管理装置10の統計処理部12により生成された燃費統計を受信し、統計記憶部111に記憶する。また、車載送受信部110は、自車両の車載装置2000側が取得する位置情報を含む燃費情報を燃費情報管理装置10へ向けて送出する。車載送受信部110は、燃費情報に加えて、燃費要因(道路属性、車両情報、交通状態)、その他のプローブ情報を燃費情報管理装置10へ向けて送出する。   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.

また、燃費情報収集部120は、自車両の走行時の燃費情報を収集する。先述したように、燃費情報は、燃費と、その燃費が検出された際の走行地点の位置情報を含む。この位置情報は、緯度経度情報、地図座標、交差点名、施設名その他の走行地点を特定できる情報である。走行時に収集された燃費情報はメモリ1211に蓄積される。なお、蓄積する燃費情報には、その位置情報に対応する燃費要因を含めてもよい。その場合、燃費情報収集部120は、燃費要因がマッピングされた地図情報301を参照し、燃費情報の走行位置に対応する燃費要因を検索し、その燃費情報と対応づけてメモリ1211に記憶する。なお、燃費情報収集部120は、燃費情報以外に、速度情報、リンク通過所要時間などの交通に関するプローブ情報を収集し、蓄積することもできる。   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.

また、燃費算出部130は、燃費情報収集部120により収集された燃費情報に基づいて、車両の燃費の増減に影響を与える燃費要因がマッピングされた地図情報301を参照し、自車両の燃費要因ごとの燃費情報を算出する。つまり、燃費算出部130は、自身が搭載された自車両について、自車両が走行経験に基づいて、所定の燃費要因下における自車両の実際の燃費情報を算出する。すなわち、車種、車型、排気量が特定された自車両固有について、走行時の気候、走行時刻、走行時の天候などの所定の条件下における、所定の燃費要因下(所定の走行リンクを通過、所定の勾配の上り坂を通過など)での燃費情報を算出する。燃費情報の算出手法は特に限定されないが、燃費算出部130は、所定の燃費要因ごとの燃費の統計をとり、その平均値、中央値、最大値、最頻値などの代表値を算出し、その値を自車両の燃費要因ごとの燃費情報とする。なお、燃費情報提示装置100側において、収集された燃費情報のすべてを蓄積することに不利益(記憶領域の占有、通信料金の増加)がなければ、代表値を求めることなく、収集された燃費情報のすべてをメモリ1211に蓄積してもよい。   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.

そして、評価部140は、燃費統計取得部141と、燃費評価部142とを有し、燃費算出手段130により算出された自車両の燃費要因ごとの燃費情報と、燃費情報管理装置10側の統計処理部12にて生成された燃費要因ごとの燃費統計と対比して、燃費統計に対する自車両の燃費情報の分散度を評価する。   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.

まず、燃費統計取得部141は、図5(A)に示すような燃費統計を燃費統計管理装置10から取得する。燃費統計取得部141は、燃費算出部130により算出された自車両の燃費情報の燃費要因と共通する燃費要因についての燃費統計を取得する。燃費統計取得部141は、評価時に必要な燃費統計の取得を燃費情報管理装置10へ要求してもよいし、予め蓄積された燃費統計の中から必要な燃費統計を選択して取得してもよい。   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.

続いて、燃費評価部142は、燃費算出部130により算出された燃費情報と、燃費統計取得部141により取得された燃費統計を対比して燃費統計に対する自車両の燃費情報の分散度を評価する。不特定多数の車両の燃費情報に基づいて統計された燃費統計と、固有の車両性能、固有の環境において検知された自車両の燃費情報とは、通常異なる値(傾向)を示すからである。不特定多数の車両の燃費統計に対する自車両固有の燃費情報の位置づけを示す値として、分散度を求める。この分散度の算出手法は特に限定されず、燃費統計の最頻値、中央値などの代表値からのずれ量その他の偏差を分散度とすることができる。たとえば、燃費統計取得部141が、図5(A)に示す「傾斜率帯Bの上り坂を走行する車両の燃費情報の統計」を取得した場合、燃費評価部142は、図5(B)に示すように、取得した燃費統計と、燃費算出部130により算出された「傾斜率帯Bの上り坂を走行する自車両の燃費情報」とを対比し、燃費統計の最頻値からの差分aを、燃費統計に対する自車両の燃費情報の分散度として評価する。この評価により、燃費情報管理装置10により複数の車両について求められた燃費統計に対する自車両の燃費情報の位置づけを定量的に得ることができる。   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.

続いて、燃費推測部150について説明する。燃費推測部150は、入力された目的地に至る経路の燃費要因に関する燃費統計を取得し、この燃費統計と評価手段により評価された分散度とに基づいて、経路の燃費情報をそれぞれ推測する。ナビゲーション装置400は、目的地の入力を受け付け、現在位置(出発地)から目的地に至る一又は二以上の経路を探索する。燃費推測部150は、燃費要因がマッピングされた地図情報を参照して、ナビゲーション装置400により探索された経路(候補)の燃費要因、または経路(候補)に含まれる燃費要因を抽出する。そして、燃費推測部150は、抽出された各燃費要因に関する燃費統計を取得し、各燃費要因に関する燃費統計と評価部140により求められた自車両の燃費情報の分散度とに基づいて、各燃費要因下の燃費を算出し、各燃費要因下の燃費を経路ごとに合計し、経路ごとの燃費情報を推測する。   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.

例えば、目的地に至る経路Yに傾斜率帯Cの上り坂と、曲率帯Oの急カーブとが含まれる場合、燃費推測部150は、図6に示す傾斜率帯Cの上り坂を走行する車両の燃費統計と、評価部140により求められた自車両の分散度aとを取得し、燃費統計の最頻値から分散度aだけ離れた値Rを自車両の燃費情報として推測する。同様の処理を曲率帯Oの燃費要因についても実行する。そして、求めた各燃費要因(傾斜率帯Cの上り坂、曲率帯Oの急カーブ)についての燃費情報を合計し、経路Yの燃費情報を推測する。同じく、目的地に至るすべての経路(経路Y以外)について燃費情報を推測する。   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.

もちろん、経路Y(経路Yを構成するリンク)についての燃費統計を用いて、経路Yを走行する際の自車両の燃費情報を算出することができる。図7に示すようなリンクW1〜W5から構成される経路がある場合、燃費推測部150は、各リンクW1〜W5の燃費統計を取得し、自車両の燃費情報の分散度aを用いて、各リンクの燃費情報R1〜R5をそれぞれ推測する。そして、燃費情報R1〜R5を加算し、出発地(Start)から目的地(Goal)までの経路の燃料情報を推測する。   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.

また、燃費推測部150は、リンクW1〜W5の燃費統計を用いることなく、各リンクに含まれる道路の勾配、標高、曲率、信号の有無といった燃費要因ごとの燃費統計を用いて、各リンクの燃費情報を推測することもできる。なお、各リンクに複数の燃費要因が含まれる場合は、燃費要因ごとに推測された燃費情報を加算すればよい。   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.

このように、前もって、所定の燃費要因について燃費統計に対する自車両の燃費情報の分散度(燃費統計に対する位置づけ)を評価しておくため、自車両が実際には走行したことがない経路についても、その経路の燃費統計を用いて自車両の燃費情報を算出することができる。つまり、自車両が走行したことがなくても、他車両が走行した際の燃費情報を利用して、自車両固有の条件が考慮された燃費情報を算出することができる。   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.

さらに、経路探索部160は、推測された各経路の燃費情報に基づいて、燃費を指標とする経路を探索する。本実施形態の経路探索部160は、燃料消費量(又は二酸化炭素の排出量)が少ない経路を優先する探索を行う。経路探索部160は、燃費のほか、所要時間、所要料金、走行距離、走行道路種別の何れか一つ以上の指標に基づいて経路候補を探索する。ユーザは燃費以外の指標も考慮して経路を選択するからである。ちなみに、燃費以外の指標に基づいて探索された経路は、後述する燃費情報表示部170により表示される。そして、ユーザから入力された一の経路を選択する選択命令に従い、選択された経路情報が出力される。   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.

次に、燃料情報表示部170について説明する。燃料情報表示部170は、編集部171と、選択受付部172と、出力部173とを備え、経路探索部160により探索された経路と、この経路について推測された燃費情報と、この経路に含まれる燃費要因と、その燃費要因が燃費に与える影響とを含む情報を表示する。   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.

編集部171は、経路探索部160により探索された経路と、その経路の燃費要因と、燃費要因が燃費に与える影響とが対応づけられた表示情報を編集する。表示態様は特に限定されないが、本実施形態の編集部171は、経路の傍らに燃費要因及びその燃費要因が燃費に与える影響が表示される表示情報を編集する。燃費要因の表示位置は、燃費要因の実際の位置と経路との位置関係に応じた位置に表示することが好ましい。   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.

このように、経路と燃費要因とその影響とを対応づけて表示することにより、経路のどこに、どのような燃費要因が存在し、どのような影響を与えるのか(燃費の増減)を、総合的に一目で認識させることができる。ユーザは、経路、燃費要因及び燃費要因の影響が対応づけられた情報を視認することにより、探索された経路の燃費の内訳を理解し、経路ごとの燃費について妥当な判断をすることができる。また、経路上の燃費要因の位置及びその影響を総合的に認定できるため、燃料消費量を増加させる燃費要因を避けた新たな経路を探索することができる。さらに、経路(候補)全体の燃費情報に加えて、各経路(候補)のそれぞれの燃費情報の内訳を詳細に示すことができるため、燃料情報の内訳を検討してから一の経路に絞り込み又は他の経路を探索させ、要求を満たす経路の案内を出力させることができる。   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.

また、編集部171は、経路とともに燃費要因を表示する場合は、各燃費要因の内容に予め対応づけた要因表示画像を表示する表示情報を編集するとともに、燃費要因が燃費に与える影響を表示する場合は、燃費に与える影響の内容に予め対応づけた影響表示画像を表示する表示情報を編集する。要因表示画像及び影響表示画像の一例を図8に示す。要因表示画像は燃費要因の内容を連想できる画像であれば、特に限定されず任意に定義することができる。同じく影響表示画像は燃費要因が燃料消費量に与える影響の内容を連想できるも画像であれば、特に限定されず任意に定義することができる。また影響の内容に応じて影響表示画像の表示サイズを変化させてもよい。   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.

また、編集部171は、燃費要因が燃費を悪化させる場合は、その燃費要因および/または燃費要因が燃費に与える影響を、赤色を含む暖色系の色で示し、燃費要因が燃費を向上させる場合は、その燃費要因および/または燃費要因が燃費に与える影響を、青色を含む寒色系の色で表示する表示情報を編集する。このため、本実施形態では、図8に示すように、燃費要因(要因表示画像を含む)および/または燃費情報(影響表示画像を含む)の表示色を予め定義する。   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.

編集部171により編集された表示情報の一例を図9に示す。図9に示すように、出発地から目的地に至る経路とともに、その経路に存在する燃費要因(上り坂、渋滞度高、下り坂)を要因表示画像で表示する。なお、要因表示画像は、その燃費要因が存在する位置に対応する位置に表示する。また、要因表示画像とともにその影響を示す影響表示画像を表示する。つまり、表示された経路上に、上り坂のある位置を要因表示画像で表示するとともに、上り坂によって燃料消費量が増加する旨を影響表示画像で表示する。   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.

なお、渋滞度、走行速度、通過所要時間などは、経路の所定範囲において発生するため、経路の色を変化させ、又は経路を点滅させることにより渋滞度が高いことを表示する。つまり、編集部171は、外部から取得する渋滞情報(渋滞区間、混雑区間、順調走行区間)を、探索された経路に重畳させて表示する。なお、渋滞度、走行速度、通過所要時間などは、VICS(Vehicle Information and Communication System)から取得する。   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).

なお、編集部171は、図9に示すように、各リンクの燃料消費量が積分された、経路全体の燃料消費量及び燃料の料金を表示情報に含める。さらに、編集部171は、各リンクの燃費*リンク長から求められる各リンクの燃料消費量、各リンクの燃料燃費量を積分して求められる経路の総燃料消費量、経路の総燃料消費量 / 経路の距離により求められる経路の平均燃等を表示情報に含めることができる。   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.

このように、燃費要因の存在及び存在位置、並びに燃費要因が燃費に与える影響を経路とともに表示することにより、目的地までの燃費情報の内訳を一目で視認することができる。   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.

また、編集部171は、経路探索部160により探索された経路のうち一の経路が選択された場合に表示される表示情報を編集する。編集部171は、選択された経路について、その経路の燃費要因と、燃費要因が燃費に与える影響とが対応づけられた表示情報を編集する。表示の態様は特に限定されず、燃費要因及びその影響については予めグレーアウトにより非表示とさせておき、カーソルやタッチパネル等で経路を選ぶと、そのグレーアウトを外して、燃費要因及びその影響を表示するようにしてもよい。表示態様の一例を示すと、図9に示すように、実線で表わされた経路と点線で表わされた経路とがある場合、編集部171は、ユーザにより選択された経路(カーソルが当てられた経路、又はタッチパネルへの入力により選択された)経路についてのみ、表燃費要因、燃費要因の影響が表示される表示情報を編集する。これより、ユーザが情報を欲する経路についてのみ詳細な燃費情報を提供することができる。なお、編集部171は、選択された経路以外の経路についても、その経路と、経路の燃費要因と、燃費要因が燃費に与える影響とを対応づけて表示する表示情報を編集してもよい。これらの表示モードはユーザの入力により切り替え可能であることが好ましい。   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.

また、図10に示すように、編集部171は、燃費要因の内容、燃費要因通過時の燃費をテキスト情報で表示する表示情報を編集することができる。   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.

さらに、編集部171は、燃費情報を二酸化炭素の排出量により表示する表示情報を編集する。例えば、図10に示すように、燃費とともに二酸化炭素の排出量を表示することができる。二酸化炭素の排出量は数字で示してもよいし、大小を示す画像で表示してもよい。   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.

加えて、編集部171は、経路探索部160により探索された経路が表示される領域とは別の領域に、経路ごとの燃費要因と、燃費要因が燃費に与える影響とを対応づけて表示する表示情報を編集する。経路(地図情報)を含まない燃費要因等の表示情報の一例を図11に示す。図11に示すように、編集部171は、経路1〜3の上り勾配及び下り勾配をそれぞれ示すとともに、燃費要因が燃費に与える影響を示す影響表示画像を含む表示情報を編集する。また、編集部171は、各経路1〜3の所要時間、有料道路の料金、燃料消費量、燃料料金を表示情報に含める。   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.

選択受付部172は、ユーザからの経路選択命令を受け付ける。出力部173は、選択受付部172を介して選択された経路を出力する。   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.

そして、モニタ1731は、図9〜11に例示する表示情報を画面に表示する。   The monitor 1731 displays the display information illustrated in FIGS. 9 to 11 on the screen.

なお、燃費要因及び燃費要因が与える影響は、その燃費要因の位置とともに音声にて出力してもよい。この場合、編集部171は、「○○駅踏切で燃費がダウンします」というように、燃費要因の位置とその影響がわかるテキスト情報を編集する。   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”.

次に、本実施形態の情報処理システム1000の制御手順を説明する。図12は情報処理システム1000の燃費情報提示装置100−1,100−2,100−nおよび燃費情報管理装置10の制御手順を説明するためのフローチャートである。   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.

まず、燃料情報提示装置100の燃費情報収集部120は、自車両の燃費情報を検出する(S101)。燃費情報収集部120は、予め定義された燃費要因がマッピングされた地図情報を参照し(S102)、燃費情報と燃費要因とを対応づけてメモリ1211に格納する(S103)。車載送受信部110は、所定のタイミングで、収集された燃費情報を燃費情報管理装置10へ送出する(S104)。送出のタイミングは特に限定されず、通信機能を利用する操作を行った場合や、予め定めた所定周期で収集された燃費情報(プローブ情報)を送出する。   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.

さらに、燃費算出部130は、収集された自車両の燃費情報に基づいて、自車両の燃費要因ごとの燃費情報を算出する(S105)。自車両の燃費情報の算出は、所定周期で実行してもよいし、その燃費要因についての燃費情報が新たに取得されたタイミングで実行してもよい。   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.

サーバ3000側の燃費情報管理装置10の燃費情報集約部11は、不特定多数の車両(プローブ車両)に搭載された車載送受信部110から送られてきた燃費情報を集約する(S120)。そして、統計処理部12は、集約された燃費情報が燃費要因ごとに統計された燃費統計を生成する(S121)生成された燃費統計は、統計記憶部121に記憶する。プローブ車両(車載装置2000)の情報の収集、サーバ3000の情報の集約、統計処理は所定のタイミングで繰り返される。   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.

燃費情報提示装置100は、ユーザから目的地が入力されたことをトリガとして、燃費情報の提示処理を開始する(S106)。目的地は、燃費情報提示装置100に直接入力されてもよいし、車載LANにて接続されたナビゲーション装置400を介して入力されてもよい。   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.

評価部140は、自車両の燃費が算出された燃費要因についての燃費統計を燃料情報管理装置10へ要求する(S108)。要求する燃費統計の燃費要因の特定手法は特に限定されず、最も新しい燃費情報についての燃費要因としてもよいし、燃費情報の収集量が最も多い燃費要因としてもよい。   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.

この要求に呼応して、燃費情報管理部10の統計送出部122は、要求に係る燃費要因についての燃費統計を燃費情報提示装置100へ送出する(S123)。   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).

評価部140の燃料統計取得部141は、要求に係る燃費統計を取得する。そして燃費評価部142は、S105で算出された自車両の燃費情報と、燃費統計とを対比して、燃費統計に対する自車両の燃費情報の分散度を評価する(S108)。燃費評価部142は、燃費統計の代表値(平均値、中央値、最頻値など)との差分を分散度として得る。   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.

なお、分散度を求める際に対比される自車両の燃費情報の燃費要因と、燃費統計の燃費要因とは共通するものであることが好ましい。燃費要因の共通性を判断する際には、燃費に与える影響が共通するものとして予め定義された燃費要因であるか否かを判断することにより行う。燃費要因の共通性は、形式的な一致に拘泥せず、燃費に与える影響の共通性に基づいて適宜定義することができる。   In addition, it is preferable that the fuel consumption factor of the fuel consumption information of the own vehicle and the fuel consumption factor of the fuel consumption statistics to be compared when determining the degree of dispersion are common. When determining the commonality of the fuel consumption factors, it is performed by determining whether or not the fuel consumption factors are predefined as having a common influence on the fuel consumption. The commonality of the fuel consumption factors can be appropriately defined based on the commonality of the influence on the fuel consumption, regardless of the formal agreement.

続いて、燃費推測部150は、目的地に至る経路に含まれる燃費要因に関する燃費統計を燃費情報管理装置10に要求する(S109)。統計送出部122は要求に係る燃費統計を燃費情報提示装置100へ送出する(S124)。ちなみに、目的地に至る経路の候補は、車載LANで接続されたナビゲーション装置400から取得してもよいし、経路探索部160から取得してもよい。   Subsequently, the fuel consumption estimation unit 150 requests the fuel consumption information management apparatus 10 for fuel consumption statistics regarding fuel consumption factors included in the route to the destination (S109). The statistics sending unit 122 sends the fuel consumption statistics related to the request to the fuel consumption information presentation device 100 (S124). Incidentally, the candidate for the route to the destination may be acquired from the navigation device 400 connected via the in-vehicle LAN, or may be acquired from the route search unit 160.

そして、燃費推測部150は、取得した燃費統計とS108にて得た分散度とに基づいて、経路候補の燃費情報を推測する(S110)。   And the fuel consumption estimation part 150 estimates the fuel consumption information of a route candidate based on the acquired fuel consumption statistics and the dispersion degree obtained in S108 (S110).

経路探索部160は、推測された燃費情報に基づいて、燃料消費量が少ない(又は排出する二酸化炭素量が少ない)経路を優先的に探索する(S111)。   The route search unit 160 preferentially searches for a route with a small fuel consumption (or a small amount of carbon dioxide to be discharged) based on the estimated fuel efficiency information (S111).

燃費情報表示部170の編集部171は、探索された経路と、経路について推測された燃費情報と、経路の燃費要因と、その燃費要因が燃費に与える影響とを含む表示情報を編集する(S112)。   The editing unit 171 of the fuel consumption information display unit 170 edits display information including the searched route, the fuel consumption information estimated for the route, the fuel consumption factor of the route, and the influence of the fuel consumption factor on the fuel consumption (S112). ).

出力部173は、編集された表示情報を出力する(S113)。ユーザは、経路ごとに表示された燃費情報、燃費要因及び燃費要因が与える影響を参考に、案内を求める経路を選択する。選択受付部172に入力された選択命令に従い、選択された経路の案内情報を表示し、誘導を実行する(S115)。   The output unit 173 outputs the edited display information (S113). The user selects a route for which guidance is sought with reference to the fuel efficiency information displayed for each route, fuel efficiency factors, and the influence of fuel efficiency factors. According to the selection command input to the selection receiving unit 172, the guide information of the selected route is displayed and guidance is executed (S115).

自車両は、案内情報を参考に走行を開始し(S116)、S101以降の処理を実行する。   The host vehicle starts traveling with reference to the guidance information (S116), and executes the processing after S101.
