実施の形態１．
以下、この発明の実施の形態１を図１、図２に基づいて説明する。
図１は、この発明の実施の形態１の車両間通信情報処理装置の概略構成図を示す。
図１において、１は、この発明の車両間通信情報処理装置であり、車両内外の検出情報から自車両の走行履歴５を生成するセンサ処理部２（詳細は後述する。）と、他車両との間で車両間通信を形成するための車両間ネットワーク通信部３と、他車両から受信した他車両の走行履歴情報を処理し適切な経路選択を行なうデータ処理部４を備えている。
また、従来のナビゲーション装置に接続されているものと同様の、ＧＰＳ受信機１０、ジャイロセンサ１１、車速パルス１２などの、自車両の現在位置や、向き、車速等を測定する測定手段と、サイドブレーキ１３、ライト１４、ワイパー１５、ドア１６など、自車両の各部位の動作状態を検出する状態検出手段が備えられており、これら測定手段および状態検出手段の検出情報がセンサ処理部２に入力されるよう構成されている。 Embodiment 1 FIG.
A first embodiment of the present invention will be described below with reference to FIGS.
1 is a schematic configuration diagram of an inter-vehicle communication information processing apparatus according to Embodiment 1 of the present invention.
In FIG. 1, reference numeral 1 denotes an inter-vehicle communication information processing apparatus according to the present invention, which includes a sensor processing unit 2 (details will be described later) that generates a travel history 5 of the host vehicle from information detected inside and outside the vehicle, and other vehicles. A vehicle-to-vehicle network communication unit 3 for forming vehicle-to-vehicle communication, and a data processing unit 4 for processing travel history information of other vehicles received from other vehicles and selecting an appropriate route.
In addition, measurement means for measuring the current position, direction, vehicle speed, etc. of the host vehicle, such as a GPS receiver 10, a gyro sensor 11, and a vehicle speed pulse 12, similar to those connected to a conventional navigation device, The state detection means for detecting the operation state of each part of the host vehicle such as the brake 13, the light 14, the wiper 15, and the door 16 is provided. It is configured to be.

次に、センサ処理部２について説明する。
センサ処理部２は、ＧＰＳ受信機１０から入手できる時刻と位置情報を基本とし、ジャイロセンサ１１によって得られる向き、車速パルス１２によって得られる走行スピード、
さらに、サイドブレーキ１３、ライト１４、ワイパー１５等の状態検出手段から得られる車両各部位の動作状態から、自車両の走行履歴を生成するものである。
例えば、ジャイロセンサ１１により一定角度以上の動きを検出した場合には、曲がり角、あるいは交差点を曲がったと判断し、その時点での履歴を蓄積する。
頻繁にサイドブレーキのＯＮ／ＯＦＦがされれば、極度の渋滞が発生していると予想できるし、高速道路上にてドア１６の開閉をする車があれば、その車は停止しており事故があった可能性がある。
また、ライト１４やワイパー１５のＯＮ／ＯＦＦも走行履歴を蓄積するトリガーとなる。
すなわち、昼間、トンネル内でないにもかかわらず、ライトが点灯された場合、天候が悪いことが予想できる。同時にワイパーも動いていれば厚い雲に覆われて雨が降っている可能性がある。
このように、センサ処理部２は、各検出手段からの検出情報に基いて走行履歴を生成し、時間、あるいは、距離ごとに、あるいは、各センサの状態変化をトリガーにして走行履歴を蓄積するものである。 Next, the sensor processing unit 2 will be described.
The sensor processing unit 2 is based on the time and position information that can be obtained from the GPS receiver 10, the direction obtained by the gyro sensor 11, the traveling speed obtained by the vehicle speed pulse 12,
Furthermore, the travel history of the host vehicle is generated from the operation state of each part of the vehicle obtained from the state detection means such as the side brake 13, the light 14, and the wiper 15.
For example, when the gyro sensor 11 detects a motion of a certain angle or more, it is determined that the vehicle turns at a corner or an intersection, and the history at that time is accumulated.
If the side brakes are frequently turned on and off, it can be expected that heavy traffic has occurred, and if there is a car that opens and closes the door 16 on the highway, the car has stopped and an accident has occurred. There may have been.
Moreover, ON / OFF of the light 14 and the wiper 15 also serves as a trigger for accumulating the travel history.
That is, it can be expected that the weather is bad when the light is turned on in the daytime but not in the tunnel. At the same time, if the wiper is moving, it may be covered with thick clouds and raining.
In this way, the sensor processing unit 2 generates a travel history based on the detection information from each detection means, and accumulates the travel history for each time or distance, or triggered by a change in the state of each sensor. Is.

この発明の車両間通信情報処理装置は以上のように構成され、生成、蓄積された走行履歴情報は、車両間ネットワーク通信部３を通して他車両に送信され、車両間通信ネットワーク上で相互にデータ交換され、自車両は、他車両からの走行履歴情報を受信してデータ処理部４が処理し、適切な経路選択を行なうものである。   The inter-vehicle communication information processing apparatus of the present invention is configured as described above, and the generated and accumulated travel history information is transmitted to other vehicles through the inter-vehicle network communication unit 3 and exchanges data with each other on the inter-vehicle communication network. Then, the host vehicle receives the travel history information from the other vehicle, and the data processing unit 4 processes it to select an appropriate route.

図２は、車両Ａを車両Ｂが追尾していく様子を示す図である。車両Ａの走行履歴２１を車両Ｂが受信し、車両Ａの履歴通りに走行することができる。複数の車両で同じ目的地に向かう場合に同じ経路で同じ目的地に着くことが可能である。また、途中で車両Ａが目的地を変えた場合にも、車両Ｂは迷わずついていくことができる。 FIG. 2 shows an example of route selection using the above-described inter-vehicle communication information processing apparatus.
FIG. 2 is a diagram illustrating a state in which the vehicle B tracks the vehicle A. The vehicle B receives the travel history 21 of the vehicle A and can travel according to the history of the vehicle A. When traveling to the same destination with multiple vehicles, it is possible to arrive at the same destination on the same route. Further, even when the vehicle A changes its destination on the way, the vehicle B can get lost.

図３は、この発明の実施の形態２の経路選択を示すもので、車両間ネットワーク通信部を通して受信した他車両からの走行履歴を用いて、車両Ａが通過した経路に渋滞が発生していたことを検出し、車両Ｂが迂回路を設定した様子を示すものである。
すなわち、車両Ａの走行履歴において、地点αから地点βまでの距離と通過時間から、特定のスピード以下の場合に渋滞が発生していたと判断することができる。あるいは、頻繁にサイドブレーキのＯＮ／ＯＦＦがなされておれば、極度の渋滞が発生していたと判断することができる。 Embodiment 2. FIG.
FIG. 3 shows route selection according to the second embodiment of the present invention. Congestion has occurred in the route that vehicle A has passed using the travel history from other vehicles received through the inter-vehicle network communication unit. This shows that the vehicle B has set a detour.
That is, in the travel history of the vehicle A, it can be determined from the distance from the point α to the point β and the passage time that traffic congestion has occurred at a specific speed or less. Alternatively, if the side brake is frequently turned ON / OFF, it can be determined that an extreme traffic jam has occurred.

このようにこの発明の実施の形態２によれば、走行履歴情報から自車両の経路上に渋滞箇所があることを確実に把握することができるので、事前にそれを避ける迂回路３０を設定することができる。   As described above, according to the second embodiment of the present invention, it is possible to surely recognize that there is a traffic jam location on the route of the host vehicle from the travel history information. be able to.

なお、渋滞の検出以外にも、前述したように、他車両のライトやワイパーの動作状態から、経路上の天候状態を予測することもでき、このような悪天候を回避するための迂回路も容易に設定することができる。   In addition to detecting traffic jams, as described above, the weather conditions on the route can be predicted from the operating conditions of the lights and wipers of other vehicles, and detours to avoid such bad weather are easy. Can be set to

If there is a vehicle that has traveled the same route as the host vehicle, it is easy to estimate the arrival time to the destination from the travel history of the vehicle. FIG. 4 shows a case where there is no single vehicle that has traveled the same route as the host vehicle.
In FIG. 4, when it is desired to obtain the arrival time from point S to point G, three traveling histories 21 to 23 of vehicle A to vehicle C are used.
The points S to α are calculated from the travel history 23 of the vehicle C. From the point α to the point β is calculated from the travel history 22 of the vehicle B. From the point β to the point G is calculated from the travel history 21 of the vehicle A.
