If a communication enable / disable determination request is received, the process flow proceeds to step S22. If not received, the process flow returns to step S21.
- step S22 a communication enable determination is transmitted. Note that the information transmission device 5 mounted on the host vehicle 3 determines whether or not the communication enable determination has been received in step S2. In step S23, it is determined whether the communication device 15 has received an information provision request. The information provision request is transmitted by the information transmission device 5 mounted on the host vehicle 3 in the step S3. If an information provision request is received, the process flow proceeds to step S24. If not received, the process flow proceeds to step S25.

Abstract
Description
1.電子制御装置1の構成
電子制御装置1の構成を図1に基づき説明する。電子制御装置1は、車両に搭載される車載装置である。電子制御装置1は、複数の車両にそれぞれ搭載されている。以下では、電子制御装置1を搭載する複数の車両のうち、任意の一台を自車両3とし、その他の車両を他車とする。ここでは、自車両3に搭載された電子制御装置1の構成を説明するが、他車に搭載された電子制御装置1も同様の構成を有する。
運転制御装置7は、自動運転に対応する制御を行うことができる。自動運転に対応する制御としては、以下のものがある。
(ii)後述するセンサ16を用いて障害物を検出し、その障害物と自車両3との衝突を避けるために減速、操舵等を行う制御。
(iv)先行車がない場合、目標速度を維持しながら走行する制御。
(vi)センサ16を用いてレーン内における自車両3の相対位置を取得し、レーンから自車両3が逸脱しないように操舵、減速等を行う制御。
アクチュエータ17は、運転制御装置7からの指令に応じて、自車両3のエンジン、ブレーキ、ステアリング等に対する操作を行う。また、アクチュエータ17は、運転制御装置7からの指令通りに操作を行えたか否か、及び、操作の結果(例えば、運転制御装置7からの指令が「車速を50Km/hにせよ」というものであった場合、操作の結果、車速が51Km/hになったこと)を、運転制御装置7に応答する。
自車両3の情報伝達装置5が実行する情報伝達処理を図2に基づき説明する。
ステップS1では、情報取得ユニット9が、通信機15を用いて通信可否判定依頼を送信する。
ステップS4では、情報Iを受信した否かを情報取得ユニット9が判断する。情報Iとは、前記ステップS3で送信した情報提供依頼に応じて、他車に搭載された情報伝達装置5が後述するステップS24において送信した情報である。情報Iには、以下の内容が含まれる。
(b)自動運転に関する他車の機能を表す情報。
(c)自動運転に関する他車の予定を表す情報。
(e)他車に搭載されたセンサ16により取得した、他車の周囲に存在する車両の位置や速度等を表す情報。
(g)他車の行き先を緯度、経度により表す情報。
(i)行き先までのルートにおける、直線部、直線部の継続距離、勾配、勾配の継続距離、カーブ半径、カーブの継続距離、カント(バンク)、カントの継続距離等を表す情報。
前記(b)の情報が表す機能としては、前記(i)~(vii)の制御を行う機能が挙げられる。また、前記(c)の予定としては、自動運転のオンオフ切り替え予定、自動運転における制御モードの変更予定、自動運転における操舵(右左折や車線変更)の予定、及び自動運転における加減速や停止の予定、速度計画等が挙げられる。
ステップS5では、情報処理ユニット11が、前記ステップS4で受信したと判断した情報Iを運転制御装置7に出力する。また、情報処理ユニット11は、情報Iに基づく報知をディスプレイ19及びスピーカ21を用いて行う。具体的には、情報Iの内容に対応する文字や画像等をディスプレイ19上に表示し、情報Iの内容に対応する音声をスピーカ21から出力する。自車両3のドライバは、ディスプレイ19の表示を見、スピーカ21の音声を聞くことで、情報Iの内容を知ることができる。
自車両3の運転制御装置7が実行する運転制御処理を図3に基づき説明する。ステップS11では、情報Iを取得したか否かを判断する。この情報Iは、前記ステップS5において情報伝達装置5が出力したものである。情報Iを取得した場合は処理の流れはステップS12に進み、情報Iを取得しなかった場合は処理の流れはステップS11の前に戻る。
先行車が送信元である情報Iに自動運転中であるという情報、及びその先行車の予定(例えば速度計画)が含まれる場合、前記(iii)の制御における先行車と自車両3との目標車間距離を、通常よりも小さくする。その結果、交通容量を増加させることができる。また、先行車は自動運転中であり、運転制御装置7は自動運転における予定を取得しているので、目標車間距離を小さくしても、安全性は低下しにくい。
特に、速度を合わせる対象である他車が、“ルート上にある信号機の表示予定を路車間通信により取得し、赤の表示で停止する回数又は時間がなるべく少なくなるように、または、赤の表示に対し緩やかに減速又は停止できるように速度計画を作成する機能”を有する場合は、他車の速度に合わせて走行する自車両も、赤の表示による停止や加減速を抑制でき、燃費性能が一層向上する。
例えば、前記(ii)の制御において、情報Iに含まれる他車の予定を利用し、その情報Iの送信元である他車との衝突を避けるために減速、操舵等を行う。その結果、自車両3の安全性が向上する。
他車に搭載された情報伝達装置5(特に送信ユニット13)が実行する情報送信処理を図4に基づき説明する。
ステップS21では、通信機15において通信可否判定依頼を受信したか否かを判断する。なお、通信可否判定依頼は、前記ステップS1において、自車両3に搭載された情報伝達装置5が送信したものである。通信可否判定依頼を受信した場合は処理の流れはステップS22に進み、受信しなかった場合は処理の流れはステップS21の前に戻る。
ステップS23では、通信機15において情報提供依頼を受信したか否かを判定する。なお、情報提供依頼は、前記ステップS3において、自車両3に搭載された情報伝達装置5が送信したものである。情報提供依頼を受信した場合は処理の流れはステップS24に進み、受信しなかった場合は処理の流れはステップS25に進む。
(1A)自車両3に搭載された情報伝達装置5は、情報Iを他車から取得し、運転制御装置7に出力する。運転制御装置7は、情報Iに基づき、自車両3の自動運転における制御モードを変更する。そのことにより、自車両3の動きを最適化することができる。
以上、本発明の特定の実施形態について説明したが、本発明は上記特定の実施形態に限定されることなく、種々の形態を採り得る。
