Description

本発明は、交通事故につながる自動車の暴走等を制御する技術に関する。  The present invention relates to a technique for controlling the runaway of an automobile leading to a traffic accident.

通学中の痛ましい交通事故が相次いだことを受け、文部科学省、警察庁、国土交通省は住宅地にある通学路について、速度制限を法定速度などから時速30キロ以下にすることが望ましいなどとした通学路の安全対策に関する提言をとりまとめた。
しかしながら、ドライバーのブレーキペダルとアクセルペダルの踏み間違え、居眠り運転、脇見運転など、自動車が暴走することは速度を制限したとしても起こりうる。
In response to a series of painful traffic accidents while attending school, the Ministry of Education, Culture, Sports, Science and Technology, the National Police Agency, and the Ministry of Land, Infrastructure, Transport and Tourism said it would be desirable to limit the speed limit to 30 kilometers per hour from the legal speed for commuting routes in residential areas. The recommendations regarding the school road safety measures were compiled.
However, if the driver's brake pedal and accelerator pedal are mistakenly depressed, doze driving, driving aside, etc., the car can run away even if the speed is limited.

その対策として、例えばハンプ(Hump)が知られており、道路上に低いカマボコ形の障害物を設けたり、路面の一部を盛り上げて舗装することによって、道路の横断方向に幅3〜5m、高さ10〜15cm程度の出っ張りを設けることでドライバーに減速を促す方法がある。  As a countermeasure, for example, Hump is known, and by providing a low kamaboko-shaped obstacle on the road or paving by raising a part of the road surface, the width is 3 to 5 m in the transverse direction, There is a method of prompting the driver to decelerate by providing a ledge of about 10 to 15 cm in height.

また、高度交通システム「ITS(IntelligentTransportSystems)」では、先進安全自動車「ASV(AdvancedSafetyVehicle)の取り組みが行われている。
特許文献1には、走行中の道路の制限速度標識を車載カメラで認識し、インパネ上に表示することで、ドライバーが現在の走行速度が制限速度を超過しているか否かを捉えやすくすることができる発明が記載されている。
In the advanced transportation system “ITS (Intelligent Transport Systems)”, an advanced safety vehicle “ASV (Advanced Safety Vehicle)” is being tackled.
In Patent Document 1, it is easy for the driver to grasp whether or not the current traveling speed exceeds the speed limit by recognizing the speed limit sign of the road being traveled by the in-vehicle camera and displaying it on the instrument panel. The invention that can be described is described.

特開2007−199026号公報JP 2007-199026 A

このようにドライバーに減速を促す技術はあるが、あくまでもドライバーに対して警告を発するというレベルであり、やはり自動車が暴走することを完全に防止することはできない。
なお、スピードリミッターは既に実用化されているが、強制的にコントロールされることに不快感をもつドライバーは少なくない。
本発明は上記の点を鑑みてなされたものであり、通学路などの人混みが多い場所や区域、ブラインドコーナーなどの危険箇所で制限速度を超過して自動車が暴走することを防ぐ車両の速度制御システムを提供することを目的とする。
Although there is a technology that prompts the driver to slow down in this way, it is at a level that only warns the driver, and it is impossible to completely prevent the car from running away.
Although speed limiters have already been put into practical use, there are many drivers who feel uncomfortable with being forcibly controlled.
The present invention has been made in view of the above points, and is a vehicle speed control that prevents a vehicle from going out of control by exceeding a speed limit in a dangerous place such as a school road or a crowded place or area, or a blind corner. The purpose is to provide a system.

請求項1の発明は、
安全運転特定エリアの制限速度情報を持った地図情報と、走行中の位置情報に基づき、車両が安全運転特定エリアに位置するときに、走行速度が制限速度を超過しないよう車両の速度制御を行う車両の速度制御システムである。
The invention of claim 1
Based on the map information with the speed limit information of the safe driving specific area and the position information while driving, the vehicle speed control is performed so that the driving speed does not exceed the speed limit when the vehicle is located in the safe driving specific area. A speed control system for a vehicle.

請求項2の発明は、
安全運転特定エリアは、通学路、歩行者天国、公園、住宅街、駐車場、危険箇所のどれかであることを特徴とする請求項1記載の速度制御システムである。
The invention of claim 2
The speed control system according to claim 1, wherein the safe driving specific area is any one of a school road, a pedestrian street, a park, a residential area, a parking lot, and a dangerous place.

請求項3の発明は、
制限速度情報は、ネットワーク回線を介して最新情報に更新されることを特徴とする請求項1記載の速度制御システムである。
The invention of claim 3
The speed control system according to claim 1, wherein the speed limit information is updated to the latest information via a network line.

本発明によれば、予期せぬ事態によってドライバーが運転をあやまっても、安全運転特定エリア内では、制限速度を超過して暴走することを防止することができる。
なお、速度制御システムが稼働するのは安全運転特定エリア内に限定されるため、一般道や高速道路などでは通常の運転ができるのでドライバーはストレスを感じることが少なく、本速度制御システム導入の拒否感や抵抗感は押さえられる。
According to the present invention, even if the driver misbehaves due to an unexpected situation, it is possible to prevent the runaway exceeding the speed limit in the safe driving specific area.
Since the speed control system operates only in certain areas for safe driving, normal driving on ordinary roads and expressways is possible, so the driver is less likely to feel stress and refuses to introduce this speed control system. Feeling and resistance can be suppressed.

制限速度情報はインターネット等のネットワーク回線を介して常に最新情報に更新されるので、情報の新旧を心配することなく運転することができる。  Since the speed limit information is always updated to the latest information via a network line such as the Internet, it is possible to drive without worrying about new or old information.

速度制御のフローチャートSpeed control flowchart

この車両の速度制限システムにおける地図情報には、実用化されているカーナビゲーションシステムの地図情報に加え、安全運転特定エリアが設定される。
この安全運転特定エリアは、学校を含む通学路、歩行者天国、公園、住宅街、駐車場などの人混みが多い場所や区域、ブラインドコーナー、工事現場、災害地などの危険箇所、その他ドライバー自身が設定したエリアを指す。
そして、この地図情報は、この安全運転特定エリアの制限速度情報を持っていて、この制限速度情報は、インターネット等のネットワーク回線を介して常に最新情報に更新される。
なお、制限速度情報は、特許文献1に記載されている走行中の道路の制限速度標識を車載カメラで認識してデータとして取り込んでもよいし、高度交通システム(ITS)等のインフラにより無線を通じて取り込んでもよい。
In the map information in the vehicle speed limiting system, a safe driving specific area is set in addition to the map information of a car navigation system that has been put into practical use.
This safe driving specific area is a crowded place such as a school road including school, pedestrian heaven, park, residential area, parking lot, dangerous corners such as blind corners, construction sites, disaster areas, etc. Refers to the set area.
And this map information has the speed limit information of this safe driving specific area, and this speed limit information is always updated to the latest information via a network line such as the Internet.
The speed limit information may be acquired as data by recognizing a speed limit sign for a road that is running as described in Patent Document 1 with an in-vehicle camera, or may be acquired wirelessly using an infrastructure such as an intelligent transportation system (ITS). But you can.

走行中の位置情報は、GPS(全地球測位システム)衛星からの位置情報を利用する。  Position information during traveling uses position information from a GPS (Global Positioning System) satellite.

この位置情報により車両が安全運転特定エリアに位置するとき、走行速度が制限速度情報の制限速度を超過しないよう車両の速度制御を行う。
速度制御は実用化されたスピードリミッター等の技術を使用すればよい。
When the vehicle is located in the safe driving specific area based on this position information, the vehicle speed is controlled so that the traveling speed does not exceed the speed limit of the speed limit information.
For speed control, a technology such as a speed limiter put into practical use may be used.

速度制御の流れをフローチャートで示したものが図1である。
まず、位置情報が取り込まれ、車両の位置が安全運転特定エリアにある場合は、速度制御システムが稼働する。
車両の位置が安全運転特定エリアにない場合は、速度制御システムは稼働せず、通常の運転ができる。
そして、このフローは運転中は常に実行される。
このように、速度制御システムが稼働するのは安全運転特定エリア内に限定されるため、一般道や高速道路などでは通常の運転ができるのでドライバーはストレスを感じることが少なく、本速度制御システム導入の拒否感や抵抗感は押さえられる。
FIG. 1 is a flow chart showing the flow of speed control.
First, when the position information is captured and the position of the vehicle is in the safe driving specific area, the speed control system is activated.
When the position of the vehicle is not in the safe driving specific area, the speed control system does not operate and normal driving can be performed.
This flow is always executed during operation.
In this way, the speed control system operates only in a safe driving specific area, so normal driving on ordinary roads and highways can be performed, so the driver is less likely to feel stress, and this speed control system is introduced. The feeling of refusal and resistance can be suppressed.
