It has a roadinformation analysis unit 22 in addition to the daily report report creation unit, the driving quality diagnosis unit, and the behavior analysis unit of the vehicle at the time of an accident. is doing.

以下、図3のフローチャートにより、適正度診断部14および総合適正度診断部15の動作を説明する。
まず、運転者が運転操作したときの、カメラ映像、加速度センサ、GPS、ウインカーなどの運転挙動の検知データが信号処理部24で処理されて収集される(ステップS1)。つぎに、このデータが一時的にバッファメモリ8に書き込まれる(例えば、20秒間ループ)(ステップS2)。データの予備加工(ノイズ除去、圧縮処理等)がされ、収集されたデータにトリガーをかけて記録するためのトリガー条件の演算処理(危険度、時刻、タイマーなど)が行われる(ステップS3)。
Hereinafter, the operations of the appropriateness diagnosis unit 14 and the overall appropriateness diagnosis unit 15 will be described with reference to the flowchart of FIG. 3.
First, detection data of driving behavior such as a camera image, an acceleration sensor, a GPS, and a blinker when the driver performs a driving operation is processed and collected by the signal processing unit 24 (step S1). Next, this data is temporarily written in the buffer memory 8 (for example, a loop for 20 seconds) (step S2). Data is preliminarily processed (noise removal, compression processing, etc.), and trigger condition calculation processing (risk level, time, timer, etc.) for triggering and recording the collected data is performed (step S3).

その一方、適正度診断部14は、信号処理部24で処理されたデータをバッファメモリ25で一時的に記憶させたのち、例えば加速度センサ4による前後、左右の加速度のデータ(G表示)により、直前の運転挙動(急アクセル、急ブレーキ、急ハンドル)について診断する。ここではデータのG表示に比例して診断レベルが決定される。そして、運転挙動直後に状態表示器9に以下の運転挙動の適正度の診断結果が表示(報知)される(ステップS4)。  On the other hand, the appropriateness diagnosis unit 14 temporarily stores the data processed by thesignal processing unit 24 in thebuffer memory 25, and then, for example, based on the acceleration data (G display) before and after the acceleration sensor 4, Diagnose the previous driving behavior (sudden accelerator, sudden braking, sudden steering). Here, the diagnosis level is determined in proportion to the G display of the data. Then, immediately after the driving behavior, the diagnosis result of the appropriateness of the following driving behavior is displayed (notified) on the status indicator 9 (step S4).

・ 診断基準レベルの0.3Gを超える場合、適正度が「危険」レベルと診断されて、赤色のLEDのフラッシング、ブザーおよびCCDカメラ3の映像の録画(例えば、前後20秒間)が行われる。
・0.3G以下の場合、適正度が「警告」レベルと診断されて、赤色のLEDが点灯する。
・0.2G以下の場合、適正度が「注意」レベルと診断されて、黄色のLEDが点灯する。
・0.1G以下の場合、適正度が「安全」レベルと診断されて、緑色のLEDが点灯する。
When the diagnostic reference level exceeds 0.3 G, the appropriateness level is diagnosed as a “dangerous” level, and red LED flushing, buzzer, and video recording of the CCD camera 3 (for example, before and after 20 seconds) are performed.
・ If 0.3G or less, the appropriateness is diagnosed as the “warning” level, and the red LED lights up.
・ If the value is 0.2G or less, the appropriateness is diagnosed as the “caution” level, and the yellow LED lights up.
・ If 0.1G or less, the appropriateness is diagnosed as a “safe” level, and the green LED lights up.

つぎに、測定終了したか否か確認され(ステップS5)、測定終了していなければ、トリガー条件をみたすか否かが確認されて(ステップS6)、トリガー条件をみたせば、該データがメモリーカード10に書き込まれ、状態表示器9で「書き込み中」が表示される(ステップS7)。ステップS6でトリガー条件をみたさなければ、ステップS1に戻って、再びデータが収集される。ステップS5で測定終了していれば、以下のように、総合適正度診断部15により総合診断され、この結果が表示される。そして、終了条件に応じて記録、測定が終了する(ステップS8)。  Next, it is confirmed whether or not the measurement is finished (step S5). If the measurement is not finished, it is confirmed whether or not the trigger condition is met (step S6). If the trigger condition is met, the data is stored in the memory. The data is written in thecard 10 and “writing” is displayed on the status display 9 (step S7). If the trigger condition is not met in step S6, the process returns to step S1 and data is collected again. If the measurement is completed in step S5, a comprehensive diagnosis is made by the comprehensive suitability diagnosis unit 15 as follows, and the result is displayed. Then, recording and measurement are completed according to the termination condition (step S8).

前記総合適正度診断では、1日の運転業務、例えば、レコーダ部1の電源ONからOFFまで、または午前8時から午後5時までの運転終了時に、その間の適正度診断部14の診断結果を累計し、全体的な運転挙動を直ちに診断して、運転終了直後にレコーダ部1の状態表示器9に総合適正度を出力する。例えば、上記各運転挙動直後の適正度診断において、1日に「危険」、「警告」、「注意」の診断レベルのうち総合診断基準レベルの3回以上出た場合、総合適正度を判定してそのうち危険度の高い方のLEDを10秒間点滅させるとともに、スピーカからブザーをならして表示する。  In the overall suitability diagnosis, the diagnosis result of the suitability diagnosis unit 14 during one day of operation, for example, when the recorder unit 1 is turned on or off or at the end of operation from 8 am to 5 pm Cumulatively, the overall driving behavior is immediately diagnosed, and the overall appropriateness is output to thestatus indicator 9 of the recorder unit 1 immediately after the end of driving. For example, in the appropriateness diagnosis immediately after each of the driving behaviors described above, if the overall diagnosis standard level of the “Danger”, “Warning”, and “Caution” diagnosis levels appears three times or more, the overall appropriateness is determined. Then, the LED with the higher risk is blinked for 10 seconds and a buzzer is sounded from the speaker.

また、上記運転挙動の適正度診断に際して、CCDカメラ3により、前記0.3Gを超える場合、危険画像として危険発生前後の連続映像がメモリーカード10に記録されるので、事故時の解析が容易になる。これとともに、CCDカメラ3により、例えば1分毎のように間欠的に撮影した画像(写真)が記録されるので、効率的にビジュアルで通常の運転傾向を把握でき、間欠記録なのでメモリーカード10の記録量も節約できる。  In addition, when the above-mentioned driving behavior suitability diagnosis is performed, if theCCD camera 3 exceeds 0.3 G, a continuous image before and after the occurrence of a danger is recorded on thememory card 10 as a danger image, so that analysis at the time of an accident is easy. Become. At the same time, images (photographs) taken intermittently, for example, every minute are recorded by theCCD camera 3 so that the normal driving tendency can be grasped efficiently and intermittently, so that thememory card 10 The amount of recording can also be saved.

この例では、加速度センサ4による前後、左右の加速度のデータにより急アクセルなどの危険度についての適正度を診断しているが、そのほかに以下の適正度診断が例示される。
・タイミング連動診断では、例えばポンピングブレーキのようなブレーキ時における加減速度、加減速時間を計測したデータを、事前に登録した車両の速度と停止までの時間における警告、注意、安全領域を示す基準プロファイルと照合して、運行データがどの領域に一番多く存在したかで危険度の適正度を診断する。
・地図情報連動診断では、ディジタル地図データから読み出した、または事前に登録した交差点やカーブ、歩道の位置と、上記タイミング連動診断とを用いて、例えば、交差点の30m手前でウインカーを出したかで危険度の適正度を診断する。
In this example, the appropriateness degree of the danger level of the sudden accelerator or the like is diagnosed by the acceleration sensor 4 before and after, and left and right acceleration data, but the following appropriateness diagnosis is exemplified.
・ In the timing-linked diagnosis, for example, the acceleration / deceleration and acceleration / deceleration time data during braking such as pumping brake is used as a reference profile that indicates warnings, cautions, and safety areas for the vehicle speed and time to stop registered in advance. The appropriateness of the degree of risk is diagnosed based on which region the operation data is most frequently present.
-Map information linked diagnosis is dangerous because, for example, the blinker is issued 30m before the intersection using the intersection, curve, or sidewalk position read from digital map data or registered in advance and the timing linked diagnosis described above. Diagnose the appropriateness of the degree.

なお、この実施形態では、運転挙動のうち危険挙動の適正度を診断しているが、危険挙動に代えて経済挙動(エコロジー)やスムーズ挙動の適正度などを診断してもよい。  In this embodiment, the appropriateness of the dangerous behavior among the driving behaviors is diagnosed, but the appropriateness of economic behavior (ecology) and smooth behavior may be diagnosed instead of the dangerous behavior.

こうして、本発明では、適正度診断部14が、運転中に、直前の運転挙動ごとに当該運転挙動の適正度を判定し、当該運転挙動直後に、当該運転挙動の適正度についてその診断結果を報知するので、従来のように運転挙動の終了後の所定時間経過後に運転挙動を診断するのに比べて運転挙動の記憶も鮮明であり、運転者の運転挙動を適切なタイミングで診断することにより、効果的な運転指導が可能となる。また、総合適正度診断部15が、一連の運転挙動の終了直後に、当該運転挙動の総合適正度についてその診断結果を報知するので、やはり運転者の運転挙動の記憶も鮮明であり、運転者の運転挙動を適切なタイミングで診断することにより、効果的な運転指導が可能となる。  In this way, in the present invention, the appropriateness diagnosis unit 14 determines the appropriateness of the driving behavior for each immediately preceding driving behavior during driving, and immediately after the driving behavior, the diagnostic result for the appropriateness of the driving behavior is obtained. Since the notification is made, the memory of the driving behavior is clearer than the conventional case of diagnosing the driving behavior after a lapse of a predetermined time after the end of the driving behavior, and by diagnosing the driving behavior of the driver at an appropriate timing. Effective driving guidance becomes possible. Further, immediately after the end of the series of driving behaviors, the overall suitability diagnosis unit 15 notifies the diagnosis result of the overall suitability of the driving behavior, so that the driver's driving behavior is also clearly stored, and the driver By diagnosing the driving behavior of the vehicle at an appropriate timing, it is possible to provide effective driving guidance.

なお、この実施形態では、診断部12は適正度診断部14および総合適正度診断部15を有しているが、総合適正度診断部15を省略してもよい。  In this embodiment, thediagnosis unit 12 includes the appropriateness diagnosis unit 14 and the overall appropriateness diagnosis unit 15, but the overall appropriateness diagnosis unit 15 may be omitted.

なお、この運転指導装置を用いて、自動車教習所のような運転教習場所で運転中に運転挙動の適正度を診断して運転指導を行なうようにしてもよい。  Note that this driving guidance device may be used to perform driving guidance by diagnosing the appropriateness of driving behavior during driving at a driving school such as a driving school.
