（第１実施形態）
本発明の第１実施形態に係る運転支援システムの全体構成を図１に示す。本運転支援システムは、車両の駆動制御を行う駆動制御装置１０を装備した車両１に搭載される。本運転支援システムは、車速に応じた車速信号を出力する車速センサ２０、他の車両と車々間通信を行うための通信装置２１、表示装置２２および制御装置２３を備えている。また、制御装置２３には、ＧＰＳ受信機、ジャイロスコープ、地磁気センサ等からなる位置検出器（いずれも図示せず）から自車位置を特定するための信号が入力されるようになっている。 (First embodiment)
FIG. 1 shows the overall configuration of the driving support system according to the first embodiment of the present invention. This driving support system is mounted on a vehicle 1 equipped with a drive control device 10 that performs drive control of the vehicle. This driving support system includes a vehicle speed sensor 20 that outputs a vehicle speed signal corresponding to the vehicle speed, a communication device 21 for performing inter-vehicle communication with other vehicles, a display device 22, and a control device 23. In addition, a signal for specifying the vehicle position is input to the control device 23 from a position detector (all not shown) including a GPS receiver, a gyroscope, a geomagnetic sensor, and the like.

駆動制御装置１０は、各種センサ（アクセルペダルの踏み込み量に応じた信号を出力するアクセルセンサ、エンジンのスロットル開度を検出するスロットル開度センサ、エンジン回転数に応じた信号を出力するエンジン回転数センサなど）より入力される信号に基づいてエンジン制御を行うエンジンＥＣＵ、ブレーキ制御を行うブレーキＥＣＵ等（いずれも図示せず）を備えている。なお、エンジンＥＣＵのエンジン制御には、エンジンのスロットル開度制御、燃料噴射量や燃料噴射タイミングを制御する燃料噴射制御、点火時期制御などがある。 The drive control device 10 includes various sensors (an accelerator sensor that outputs a signal according to the amount of depression of the accelerator pedal, a throttle opening sensor that detects the throttle opening of the engine, and an engine speed that outputs a signal according to the engine speed). An engine ECU that performs engine control based on a signal input from a sensor or the like, a brake ECU that performs brake control, and the like (both not shown) are provided. Engine control of the engine ECU includes engine throttle opening control, fuel injection control for controlling the fuel injection amount and fuel injection timing, ignition timing control, and the like.

本実施形態における駆動制御装置１０は、制御装置２３からの指示に応じてエンジンのスロットルの開閉動作を制限することが可能となっている。これにより、自車１の加速および減速が制限され、アクセルペダル操作に応じた本来の加速および減速が得られないようにすることが可能となる。 The drive control device 10 according to the present embodiment can limit the opening / closing operation of the engine throttle in accordance with an instruction from the control device 23. Thereby, the acceleration and deceleration of the host vehicle 1 are limited, and it is possible to prevent the original acceleration and deceleration according to the accelerator pedal operation from being obtained.

表示装置２２は、ナビゲーション装置のディスプレイとして配置されたナビゲーション用表示装置、メータ内に設けられたメータ内表示装置、車両に装備された警報用表示装置により構成されている。各表示装置は、音声を出力するためのスピーカを備えている。 The display device 22 includes a navigation display device arranged as a display of the navigation device, an in-meter display device provided in the meter, and an alarm display device provided in the vehicle. Each display device includes a speaker for outputting sound.

制御装置２３は、ＣＰＵ、メモリ、Ｉ／Ｏ等を備えたコンピュータとして構成されており、ＣＰＵはメモリに記憶されたプログラムにしたがって各種処理を実施する。 The control device 23 is configured as a computer including a CPU, a memory, an I / O, and the like, and the CPU performs various processes according to a program stored in the memory.

車両Ａ、Ｂ、・・・、Ｎには、それぞれ自車両１と同様の車速センサ２０、通信装置２１および制御装置２３が備えられている。また、制御装置２３には、位置検出器（図示せず）から自車位置を特定するための信号が入力されるようになっている。なお、車両Ａ〜Ｎにおいて、自車両１と同様に、表示装置２２、駆動制御装置１０が備えられていてもよい。 Vehicles A, B,..., N are provided with a vehicle speed sensor 20, a communication device 21, and a control device 23 that are the same as the vehicle 1. In addition, a signal for specifying the vehicle position is input to the control device 23 from a position detector (not shown). Note that the vehicles A to N may be provided with the display device 22 and the drive control device 10 as in the case of the host vehicle 1.

車両Ａ、Ｂ、・・・、Ｎに搭載された制御装置２３の処理としては、位置検出器より入力される自車位置を特定するための情報に基づいて自車位置を特定する自車位置特定処理、各車両の車速センサから入力される信号に基づいて車速を特定し、通信装置２１を介して位置情報を含む車速情報を周期的に送出する車速情報送出処理がある。 As a process of the control device 23 mounted on the vehicles A, B,..., N, the vehicle position for specifying the vehicle position based on the information for specifying the vehicle position input from the position detector. Specific processing includes vehicle speed information transmission processing for specifying vehicle speed based on a signal input from a vehicle speed sensor of each vehicle and periodically transmitting vehicle speed information including position information via the communication device 21.

また、自車１に搭載された制御装置２３の処理としては、位置検出器より入力される自車位置を特定するための情報に基づいて自車位置を特定する自車位置特定処理、周辺車両から車速情報を取得して周辺車両の車速の平均値を算出し、当該周辺車両の車速の平均値と自車１の車速との差異に基づいて自車１が周辺車両に対して必要以上の加減速を実施することを判定した場合、駆動制御装置１０に加速を制限するように指示する加速制限処理がある。 Moreover, as a process of the control apparatus 23 mounted in the own vehicle 1, the own vehicle position specific process which specifies the own vehicle position based on the information for specifying the own vehicle position input from a position detector, a surrounding vehicle Vehicle speed information is obtained from the vehicle, and the average value of the vehicle speeds of the surrounding vehicles is calculated. Based on the difference between the vehicle speed average value of the surrounding vehicles and the vehicle speed of the own vehicle 1, the own vehicle 1 is more than necessary for the surrounding vehicles. When it is determined that acceleration / deceleration is to be performed, there is an acceleration limiting process that instructs the drive control device 10 to limit acceleration.

次に、図２に従って、自車１に搭載された制御装置２３によるこの加速制限処理について説明する。車両のイグニッションスイッチがオンすると本運転支援システムは動作状態となり、制御装置２３は、図２に示す処理を開始する。 Next, the acceleration limiting process by the control device 23 mounted on the host vehicle 1 will be described with reference to FIG. When the ignition switch of the vehicle is turned on, the driving support system is in an operating state, and the control device 23 starts the process shown in FIG.

まず、通信装置２１を介して周辺車両から車速情報を取得する（Ｓ１００）。具体的には、通信装置２１を介して通信可能な周辺車両から位置情報（緯度経度情報）を含む車速情報を取得する。 First, vehicle speed information is acquired from surrounding vehicles via the communication device 21 (S100). Specifically, vehicle speed information including position information (latitude and longitude information) is acquired from surrounding vehicles that can communicate via the communication device 21.

次に、自車１と同一方向に走行中の周辺車両の車速情報を抽出する（Ｓ１０２）。本実施形態では、図３に示すように、自車１の位置情報（緯度経度情報）と周辺車両の各位置情報（緯度経度情報）を用いて、自車１との距離が予め定められた基準値（例えば、３０メートル）以内に存在する周辺車両を特定する処理を繰り返し実施して自車１と同一方向に走行中の周辺車両（車群）として特定し、Ｓ１００にて取得した各周辺車両の車速情報の中から、自車１と同一方向に走行中の周辺車両の車速情報を抽出する。なお、自車１との距離が予め定められた基準値以内に存在する周辺車両を特定する処理を繰り返し実施する間に、自車１と反対方向に走行中の周辺車両は除外される。 Next, vehicle speed information of surrounding vehicles that are traveling in the same direction as the host vehicle 1 is extracted (S102). In the present embodiment, as shown in FIG. 3, the distance from the own vehicle 1 is determined in advance using the position information (latitude / longitude information) of the own vehicle 1 and the position information (latitude / longitude information) of surrounding vehicles. Each of the surroundings acquired in step S100 is identified as a surrounding vehicle (vehicle group) that is running in the same direction as the host vehicle 1 by repeatedly performing processing for identifying surrounding vehicles existing within a reference value (for example, 30 meters). From the vehicle speed information of the vehicle, vehicle speed information of surrounding vehicles that are traveling in the same direction as the host vehicle 1 is extracted. In addition, while repeatedly performing the process of specifying the surrounding vehicles whose distance from the own vehicle 1 is within a predetermined reference value, the surrounding vehicles that are traveling in the opposite direction to the own vehicle 1 are excluded.

次に、自車１と同一方向に走行中の周辺車両（車群）から取得した車速情報の平均値（平均車速）を算出する（Ｓ１０４）。 Next, an average value (average vehicle speed) of the vehicle speed information acquired from the surrounding vehicles (vehicle group) traveling in the same direction as the own vehicle 1 is calculated (S104).

次に、車速センサ２０より入力される信号に基づいて自車１の車速情報を特定する（Ｓ１０６）。 Next, the vehicle speed information of the own vehicle 1 is specified based on the signal input from the vehicle speed sensor 20 (S106).

次に、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上大きいか否かに基づいて自車１が周辺車両に対して必要以上の加速を実施したか否かを判定する（Ｓ１０８）。 Next, based on whether or not the current vehicle speed of the host vehicle 1 is higher than the reference value by the average vehicle speed of the vehicles belonging to the vehicle group, whether or not the host vehicle 1 has performed unnecessary acceleration on the surrounding vehicles. Is determined (S108).

自車１の運転者により急な加速が行われ、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上大きくなった場合、Ｓ１０８の判定はＹＥＳとなり、駆動制御装置１０へ加速を制限するように指示する（Ｓ１１０）。具体的には、加速を制限するように指示する信号を駆動制御装置１０へ送出し、Ｓ１００へ戻る。これにより、自車１は加速が制限される。 When the driver of the host vehicle 1 suddenly accelerates and the current vehicle speed of the host vehicle 1 becomes higher than the reference value than the average vehicle speed of the vehicles belonging to the vehicle group, the determination in S108 is YES, and the drive control device 10 is instructed to limit acceleration (S110). Specifically, a signal instructing to limit acceleration is sent to the drive control device 10 and the process returns to S100. Thereby, the acceleration of the own vehicle 1 is limited.

また、自車１が交通流に沿って走行しており、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上ではなくなった場合、Ｓ１０８の判定はＮＯとなり、駆動制御装置１１２へ加速の制限を解除するように指示する（Ｓ１１２）。具体的には、加速を制限するように指示する信号の送出を停止し、Ｓ１００へ戻る。このように加速の制限が解除されると、アクセルペダル操作に応じた本来の加速が可能となる。 If the vehicle 1 is traveling along the traffic flow and the current vehicle speed of the vehicle 1 is no longer equal to or higher than the reference value than the average vehicle speed of the vehicles belonging to the vehicle group, the determination in S108 is NO and the drive The control device 112 is instructed to release the acceleration limitation (S112). Specifically, transmission of a signal instructing to limit acceleration is stopped, and the process returns to S100. When the limitation on acceleration is released in this way, the original acceleration according to the accelerator pedal operation becomes possible.

上記した構成によれば、通信装置を介して、自車と同一方向に走行中の周辺車両から各車両の車速情報を取得するとともに、当該各車両の車速情報の平均値を算出し、自車の車速と周辺車両の車速の平均値（平均車速）との差異に基づいて自車が周辺車両に対して必要以上の加速を実施したことを判定した場合、駆動制御装置に加速を制限するように指示がなされるので、よりエネルギー消費（燃料消費量）の少ない走行制御を行うことができる。 According to the configuration described above, the vehicle speed information of each vehicle is acquired from the surrounding vehicle that is traveling in the same direction as the host vehicle via the communication device, and the average value of the vehicle speed information of each vehicle is calculated. If it is determined that the vehicle has accelerated more than necessary to the surrounding vehicle based on the difference between the vehicle speed of the vehicle and the average value of the vehicle speeds of the surrounding vehicles (average vehicle speed), the drive control device should limit the acceleration. Therefore, traveling control with less energy consumption (fuel consumption) can be performed.

（第２実施形態）
本発明の第２実施形態に係る運転支援システムの構成は、図１に示したものと同じである。図４に、第２実施形態に係る自車１に搭載された制御装置２３による報知処理のフローチャートを示す。上記第１実施形態では、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上大きいことを判定した場合に、駆動制御装置１０へ加速を制限するように指示する処理を実施したが、本実施形態では、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上大きいことを判定した場合に、運転者に急な加速を制限するように報知する報知処理を実施する点が異なる。以下、上記実施形態と同一部分には同一符号を付して説明を省略し、異なる点を中心に説明する。 (Second Embodiment)

In FIG. 4, the flowchart of the alerting | reporting process by the control apparatus 23 mounted in the own vehicle 1 which concerns on 2nd Embodiment is shown. In the said 1st Embodiment, when it determines with the present vehicle speed of the own vehicle 1 being more than a reference value more than the average vehicle speed of the vehicle which belongs to a vehicle group, the process which instruct | indicates to restrict | limit acceleration to the drive control apparatus 10 However, in the present embodiment, when it is determined that the current vehicle speed of the host vehicle 1 is greater than the reference value by the average vehicle speed of the vehicles belonging to the vehicle group, the driver is restricted from sudden acceleration. The point which performs the alerting | reporting process to alert | report is different. Hereinafter, the same parts as those in the above embodiment are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described.

車両のイグニッションスイッチがオンすると本運転支援システムは動作状態となり、制御装置２３は、図４に示す処理を開始する。 When the ignition switch of the vehicle is turned on, the driving support system is in an operating state, and the control device 23 starts the process shown in FIG.

Ｓ１００〜Ｓ１０８については、図２に示した加速制御処理と同様である。そして、自車１の運転者により急な加速が行われ、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上になった場合、Ｓ１０８の判定はＹＥＳとなり、加速を制限するように報知を行う（Ｓ２１０）。具体的には、加速を制限するように指示するメッセージを表示装置２２のディスプレイに表示させるとともに表示装置２２に備えられたスピーカから音声出力させる。 About S100-S108, it is the same as that of the acceleration control process shown in FIG. Then, when the driver of the own vehicle 1 suddenly accelerates and the current vehicle speed of the own vehicle 1 is equal to or higher than the reference value than the average vehicle speed of the vehicles belonging to the vehicle group, the determination in S108 is YES, and the acceleration Notification is performed so as to limit (S210). Specifically, a message instructing to limit acceleration is displayed on the display of the display device 22 and voice is output from a speaker provided in the display device 22.

It is determined whether or not (S212).

そして、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上大きくなった場合には、Ｓ２１２の判定はＹＥＳとなり、Ｓ２１２の判定を繰り返す。この間、繰り返し報知が行われる。 Then, when the current vehicle speed of the host vehicle 1 is greater than the reference value by the average vehicle speed of the vehicles belonging to the vehicle group, the determination in S212 is YES, and the determination in S212 is repeated. During this time, repeated notification is performed.

そして、自車１の現在の車速が車群に属する車両の平均車速よりも基準値以上ではなくなると、Ｓ２１２の判定はＮＯとなり、報知を終了し（Ｓ２１４）、Ｓ１００へ戻る。 Then, when the current vehicle speed of the host vehicle 1 is not equal to or higher than the reference value than the average vehicle speed of the vehicles belonging to the vehicle group, the determination in S212 is NO, the notification is terminated (S214), and the process returns to S100.

上記した構成によれば、通信装置を介して、自車と同一方向に走行中の周辺車両から各車両の車速情報を取得するとともに、当該各車両の車速情報の平均値を算出し、自車の車速と周辺車両の車速の平均値（平均車速）との差異に基づいて自車が周辺車両に対して必要以上の加速を実施したことを判定した場合、乗員に低燃費走行を促す報知が行われるので、よりエネルギー消費（燃料消費量）の少ない走行制御を行うことができる。 According to the configuration described above, the vehicle speed information of each vehicle is acquired from the surrounding vehicle that is traveling in the same direction as the host vehicle via the communication device, and the average value of the vehicle speed information of each vehicle is calculated.

（第３実施形態）
本発明の第３実施形態に係る運転支援システムの全体構成を図５に示す。本実施形態に係る運転支援システムは、図１に示した駆動制御装置１０に代えて、ＡＣＣ装置１１を備えた構成となっている。このＡＣＣ装置１１は、図１に示した駆動制御装置１０の機能に加え、先行車両との車間距離を計測し、先行車両と自車との車間距離および相対速度を検出し、設定した車間距離を保つようにスロットルアクチュエータ、ブレーキアクチュエータを制御することにより自車速度を自動制御し、先行車両の追従走行制御を行う、所謂ＡＣＣ（ＡｄａｐｔｉｖｅＣｒｕｉｓｅＣｏｎｔｒｏｌ）機能を備えたものである。 (Third embodiment)
FIG. 5 shows an overall configuration of a driving support system according to the third embodiment of the present invention. The driving support system according to the present embodiment includes an ACC device 11 instead of the drive control device 10 shown in FIG. In addition to the function of the drive control device 10 shown in FIG. 1, the ACC device 11 measures the inter-vehicle distance from the preceding vehicle, detects the inter-vehicle distance and the relative speed between the preceding vehicle and the host vehicle, and sets the inter-vehicle distance. The vehicle is equipped with a so-called ACC (Adaptive Cruise Control) function that automatically controls the own vehicle speed by controlling the throttle actuator and the brake actuator so as to maintain the following, and performs the following traveling control of the preceding vehicle.

ＡＣＣ装置１１は、先行車両と自車両の車間距離が予め定められた基準値以上になると、車間距離が基準値以上になったことを示す信号を制御装置２３へ出力するようになっている。 The ACC device 11 outputs a signal indicating that the inter-vehicle distance is equal to or greater than the reference value to the control device 23 when the inter-vehicle distance between the preceding vehicle and the host vehicle is equal to or greater than a predetermined reference value.

図６に、本実施形態に係る自車１に搭載された制御装置２３のフローチャートを示す。図６に従って、制御装置２３の処理について説明する。制御装置２３は、図２に示した加速制限処理と並行して図６に示す処理を実施する。 In FIG. 6, the flowchart of the control apparatus 23 mounted in the own vehicle 1 which concerns on this embodiment is shown. The process of the control apparatus 23 is demonstrated according to FIG. The control device 23 performs the process shown in FIG. 6 in parallel with the acceleration limiting process shown in FIG.

Ｓ１００〜１０４については、図２に示した加速制御処理と同様である。そして、ＡＣＣ装置１１から先行車両と自車１の車間距離が基準値以上になったことを示す信号を受信したか否かを判定する（Ｓ１０６）。 S100 to 104 are the same as the acceleration control process shown in FIG. Then, it is determined whether or not a signal indicating that the inter-vehicle distance between the preceding vehicle and the host vehicle 1 is equal to or greater than a reference value is received from the ACC device 11 (S106).

ここで、先行車両が交通流に沿って走行しており、車間距離が基準値以上になったことを示す信号が受信されない場合、Ｓ１０６の判定はＮＯとなり、Ｓ１００へ戻る。 Here, when the preceding vehicle is traveling along the traffic flow and a signal indicating that the inter-vehicle distance is equal to or greater than the reference value is not received, the determination in S106 is NO and the process returns to S100.

また、図７に示すように、先行車両が車群の中で加速し、車間距離が基準値以上になったことを示す信号を受信すると、Ｓ１０６の判定はＹＥＳとなり、次に、Ｓ１００〜Ｓ１０４と同様の処理を行い（Ｓ３００〜Ｓ３０４）、車群に属する車両の平均車速を算出する。 In addition, as shown in FIG. 7, when the preceding vehicle accelerates in the vehicle group and receives a signal indicating that the inter-vehicle distance is equal to or greater than the reference value, the determination in S106 is YES, and then S100 to S104. The same processing is performed (S300 to S304), and the average vehicle speed of the vehicles belonging to the vehicle group is calculated.

次に、ＡＣＣ装置１１から信号を受信する前に対して車群の平均車速が上がっていないかを判定する（Ｓ３０６）。具体的には、最新の車群の平均車速と自車の直前を走行する車両との車間距離が予め定められた閾値以上になる直前に算出された車群の平均車速を比較して、車群の平均車速が上昇していないか否かを判定する。 Next, it is determined whether the average vehicle speed of the vehicle group has increased compared to before receiving a signal from the ACC device 11 (S306). Specifically, the average vehicle speed of the latest vehicle group is compared with the average vehicle speed of the vehicle group calculated immediately before the inter-vehicle distance between the vehicle traveling immediately before the host vehicle is equal to or greater than a predetermined threshold. It is determined whether or not the average vehicle speed of the group has increased.

ここで、車群の平均車速が上昇していない場合、Ｓ３０６の判定はＹＥＳとなり、ＡＣＣ装置１１に対して加速を制限するように指示する（Ｓ３０８）。具体的には、加速を制限するように指示する信号をＡＣＣ装置１１へ送出し、Ｓ１００へ戻る。すなわち、先行車両が加速して先行車両との車間距離が予め定められた閾値以上になっても、車群の平均車速が上昇していない場合、自車１は加速が制限され、無駄な加速は行われない。 Here, when the average vehicle speed of the vehicle group has not increased, the determination in S306 is YES, and the ACC device 11 is instructed to limit acceleration (S308). Specifically, a signal instructing to limit acceleration is sent to the ACC device 11, and the process returns to S100. That is, even if the preceding vehicle accelerates and the distance between the preceding vehicle and the preceding vehicle exceeds a predetermined threshold, if the average vehicle speed of the vehicle group has not increased, the acceleration of the own vehicle 1 is limited and unnecessary acceleration is achieved. Is not done.

また、車群の平均車速が上昇している場合、Ｓ３０６の判定はＮＯとなり、図示してないが、加速を制限するように指示する信号の送出を停止し、Ｓ１００へ戻る。このように、先行車両が加速して先行車両との車間距離が予め定められた閾値以上になっても、車群の平均車速が上昇している場合には、自車１の加速は制限されない。 If the average vehicle speed of the vehicle group is increasing, the determination in S306 is NO, and although not shown, the transmission of a signal instructing to limit acceleration is stopped, and the process returns to S100. Thus, even if the preceding vehicle accelerates and the inter-vehicle distance from the preceding vehicle exceeds a predetermined threshold value, the acceleration of the host vehicle 1 is not limited when the average vehicle speed of the vehicle group increases. .

上記した構成によれば、自車の直前を走行する車両との車間距離が一定距離以上になったことを判定した場合、自車と同一方向に走行中の周辺車両の最新の平均車速と自車の直前を走行する車両との車間距離が予め定められた閾値以上になる直前に算出された平均車速を比較して、平均車速が上昇していないことを判定した場合、追従制御装置に加速を制限するように指示がなされる。すなわち、自車の直前を走行する車両が無駄な加速をして、自車の直前を走行する車両との車間距離が一定距離以上になったとしても、自車と同一方向に走行中の周辺車両の平均車速が上昇していない場合には、駆動制御装置に加速を制限するように指示するので、無駄な加速をしないようにし、無駄なエネルギーを消費しないようにすることができる。 According to the above configuration, when it is determined that the inter-vehicle distance with the vehicle traveling immediately before the own vehicle is equal to or greater than a certain distance, the latest average vehicle speed of the surrounding vehicles traveling in the same direction as the own vehicle If the average vehicle speed calculated immediately before the distance between the vehicle and the vehicle traveling immediately before the vehicle is equal to or greater than a predetermined threshold is determined and it is determined that the average vehicle speed has not increased, the tracking control device is accelerated. Is instructed to limit In other words, even if the vehicle traveling immediately before the host vehicle accelerates unnecessarily and the inter-vehicle distance from the vehicle traveling immediately before the host vehicle exceeds a certain distance, When the average vehicle speed of the vehicle is not increased, the drive control device is instructed to limit acceleration, so that unnecessary acceleration can be prevented and wasteful energy can be prevented from being consumed.

Further, the vehicles 1 to N are also equipped with fuel consumption meters.

自車１に搭載された制御装置２３は、自車１の瞬間燃費と車群に属する車両の瞬間燃費を比較して車群における自車の燃費の順位を特定し、車群における自車の燃費の順位に基づいて自車１の燃費のランク付けを行い、自車１の燃費のランクを報知するランク報知処理を実施する。 The control device 23 mounted on the host vehicle 1 compares the instantaneous fuel consumption of the host vehicle 1 with the instantaneous fuel consumption of the vehicles belonging to the vehicle group, identifies the order of the fuel consumption of the host vehicle in the vehicle group, and Based on the ranking of the fuel consumption, the ranking of the fuel consumption of the host vehicle 1 is performed, and rank notification processing for notifying the rank of the fuel consumption of the host vehicle 1 is performed.

まず、通信装置２１を介して周辺車両から燃費情報を取得する（Ｓ４００）。具体的には、通信装置２１を介して通信可能な周辺車両から位置情報（緯度経度情報）を含む燃費情報を取得する。ここでいう燃費情報は瞬間燃費である。 First, fuel consumption information is acquired from surrounding vehicles via the communication device 21 (S400). Specifically, fuel consumption information including position information (latitude and longitude information) is acquired from surrounding vehicles that can communicate via the communication device 21. The fuel efficiency information here is instantaneous fuel efficiency.

次に、自車１と同一方向に走行中の周辺車両の燃費情報を抽出する（Ｓ４０２）。本実施形態では、自車１の位置情報（緯度経度情報）と周辺車両の各位置情報（緯度経度情報）を用いて、自車１との距離が予め定められた基準値（例えば、３０メートル）以内に存在する周辺車両を自車１と同一方向に走行中の周辺車両として特定し、Ｓ４００にて取得した各周辺車両の燃費情報の中から、自車１と同一方向に走行中の周辺車両の燃費情報を抽出する。 Next, fuel consumption information of surrounding vehicles that are traveling in the same direction as the host vehicle 1 is extracted (S402). In the present embodiment, a reference value (for example, 30 meters) in which the distance from the own vehicle 1 is determined in advance using the position information (latitude / longitude information) of the own vehicle 1 and each position information (latitude / longitude information) of surrounding vehicles. ) Is identified as a peripheral vehicle that is traveling in the same direction as the own vehicle 1, and the surroundings that are traveling in the same direction as the own vehicle 1 are determined from the fuel consumption information of each peripheral vehicle acquired in S 400.

次に、自車１に搭載された燃費計から入力される信号に基づいて自車１の瞬間燃費を特定する（Ｓ４０４）。 Next, the instantaneous fuel consumption of the own vehicle 1 is specified based on the signal input from the fuel consumption meter mounted on the own vehicle 1 (S404).

次に、自車１の燃費と自車と同一方向に走行中の周辺車両の各燃費を比較して周辺車両と自車１を含む車群における自車の燃費の順位およびランクを特定する（Ｓ４０６）。 Next, the fuel consumption of the own vehicle 1 is compared with the respective fuel consumptions of the surrounding vehicles traveling in the same direction as the own vehicle, and the rank and rank of the own vehicle fuel consumption in the vehicle group including the surrounding vehicle and the own vehicle 1 are specified ( S406).

次に、車群における自車１の燃費のランクが特定ランクに位置づけられているか否かを判定する（Ｓ４０８）。本実施形態では、車群中の下位３０％を特定ランクとして、自車の燃費のランクが特定ランクに位置づけられているか否かを判定する。 Next, it is determined whether or not the fuel economy rank of the vehicle 1 in the vehicle group is positioned at a specific rank (S408). In the present embodiment, the lower 30% in the vehicle group is set as the specific rank, and it is determined whether or not the fuel efficiency rank of the own vehicle is positioned at the specific rank.

ここで、自車の燃費のランクが特定ランクに位置づけられていない場合、Ｓ４０８の判定はＮＯとなり、Ｓ４００へ戻る。 Here, when the rank of the fuel consumption of the own vehicle is not positioned at the specific rank, the determination in S408 is NO, and the process returns to S400.

また、自車の燃費のランクが特定ランクに位置づけられている場合、Ｓ４０８の判定はＹＥＳとなり、表示装置２２に自車の燃費の順位および自車の燃費のランクを表示させる（Ｓ４１０）。具体的には、自車の燃費の順位および自車の燃費のランクを表示するための情報を表示装置２２へ送出する。これにより、表示装置２２のディスプレイに自車の燃費の順位および自車の燃費のランクが表示される。 If the fuel efficiency rank of the host vehicle is positioned at the specific rank, the determination in S408 is YES, and the ranking of the fuel economy of the host vehicle and the fuel efficiency rank of the host vehicle are displayed on the display device 22 (S410). Specifically, information for displaying the ranking of the fuel consumption of the own vehicle and the rank of the fuel consumption of the own vehicle is sent to the display device 22. Thereby, the ranking of the fuel consumption of the own vehicle and the rank of the fuel consumption of the own vehicle are displayed on the display of the display device 22.

そして、Ｓ４００へ戻り、上記した処理を再度実施する。自車の燃費のランクが特定ランクから外れ、自車の燃費のランクが特定ランクに位置づけられなくなると、Ｓ４０８の判定はＮＯとなり、表示装置２２による自車の燃費の順位および自車の燃費のランクの表示を中止させる（Ｓ４１２）。具体的には、表示装置２２に対する自車の燃費の順位および自車の燃費のランクを表示するための情報の送出を停止する。 And it returns to S400 and implements the above-mentioned process again. If the fuel efficiency rank of the own vehicle deviates from the specific rank and the fuel efficiency rank of the own vehicle is no longer positioned at the specific rank, the determination in S408 is NO, and the fuel efficiency ranking of the own vehicle and the fuel efficiency of the own vehicle by the display device 22 are determined. The display of the rank is stopped (S412). Specifically, the transmission of information for displaying the ranking of the fuel consumption of the own vehicle and the rank of the fuel consumption of the own vehicle to the display device 22 is stopped.

上記した構成によれば、自車と同一方向に走行中の周辺車両から取得した各車両の燃費と自車の燃費を比較して周辺車両と自車を含む車群における自車の燃費の順位および燃費のランクを特定し、自車の燃費のランクが特定ランクに位置づけられていることを判定すると、乗員に自車の燃費のランクが報知されるので、車群における自車の位置づけを運転者に認識させ、環境負荷の少ない省エネ運転を誘導することが可能である。 According to the above configuration, the fuel efficiency ranking of the vehicle in the vehicle group including the surrounding vehicle and the own vehicle by comparing the fuel efficiency of each vehicle obtained from the surrounding vehicle traveling in the same direction as the own vehicle with the fuel efficiency of the own vehicle.
