以下、添付図面に基づいて、本発明の一実施形態を説明する。運転記録装置10は、契機検出手段11,契機解析手段12,記録場所変更部13,記録方法変更部14,記録内容変更部15,情報保存処理部16から構成されている。制御手段17は、記録場所変更部13,記録方法変更部14及び記録内容変更部15からなるものである。   Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The operation recording apparatus 10 includes an opportunity detection unit 11, an opportunity analysis unit 12, a recording location changing unit 13, a recording method changing unit 14, a recording content changing unit 15, and an information storage processing unit 16. The control means 17 includes a recording location changing unit 13, a recording method changing unit 14, and a recording content changing unit 15.

運転記録装置10は、車内ネットワーク20に接続されており、車内ネットワーク20より記録を開始する契機や記録すべき運転情報を取得する。車内ネットワーク20に接続された運転記録装置10において、契機検出手段11は、運転情報の記録を開始する契機(エアバッグ動作情報/加減速度情報/運転記録装置のSW動作等)を検出した場合、前記契機を契機解析手段12へ伝達する。   The driving recording apparatus 10 is connected to the in-vehicle network 20 and acquires an opportunity to start recording and driving information to be recorded from the in-vehicle network 20. In the driving recording device 10 connected to the in-vehicle network 20, when the trigger detection unit 11 detects a trigger (airbag operation information / acceleration / deceleration information / SW operation of the driving recording device, etc.) to start recording driving information, The trigger is transmitted to the trigger analysis means 12.

契機解析手段12は、契機を解析して得られる契機情報を制御手段17に伝達する。契機解析手段12は、契機がエアバッグ動作情報だった場合は事故として判断し、減速度Bが0≧B>B1だった場合は通常動作、B1≧B>B2だった場合は危険運転、B2≧Bだった場合は事故、また、操作スイッチ(図示しない)の操作によるものだった場合には運転者の意思として判断し、契機情報を決定する。   The trigger analysis unit 12 transmits the trigger information obtained by analyzing the trigger to the control unit 17. When the trigger is air bag operation information, the trigger analysis unit 12 determines that the accident is an accident. When the deceleration B is 0 ≧ B> B1, the normal operation is performed. When B1 ≧ B> B2, the dangerous driving is performed. B2 If it is ≧ B, an accident is caused, and if it is caused by an operation of an operation switch (not shown), it is determined as the driver's intention and the trigger information is determined.

記録場所変更部13は、契機情報に応じて、耐熱・耐衝撃性に優れた筐体に格納された記録素子/着脱可能な記録素子/装置内部にある記録素子/無線通信等を利用し外部へ保存可能な素子のどこに記録するのかを設定されており、契機情報に基づいて契機情報を記録すべき場所を決定し、情報保存処理部16に対し記録場所情報を伝達する。   The recording location changing unit 13 uses a recording element stored in a case with excellent heat resistance and shock resistance / detachable recording element / recording element in the device / wireless communication, etc. according to the trigger information.

That is, when the trigger information is triggered by an accident, the operation information to be recorded is encrypted as an alteration prevention measure, and key information is attached to provide browsing restrictions. When the trigger information is triggered by dangerous driving, only encryption is performed on the information. When the trigger information is triggered by the driver's intention, encryption / key information is not added.

記録内容変更部15は、予め、契機情報により運転情報を保存するかを設定されており、契機情報に基づいて記録方法情報/該当する記録内容を決定し、情報保存処理部16へ伝達する。   The recording content changing unit 15 is set in advance as to whether or not to save the operation information based on the trigger information, determines the recording method information / corresponding recording content based on the trigger information, and transmits the recording method information to the information storage processing unit 16.

情報保存処理部16は、伝達された記録場所情報/記録方法情報/記録内容に基づいて、指定された内容を、指定された方法に基づき加工し、指定された場所へ保存を行う。   Based on the transmitted recording location information / recording method information / recording content, the information storage processing unit 16 processes the specified content based on the specified method, and stores it in the specified location.

本実施形態によれば、運転情報の記録を開始する契機の種別・組み合わせにより、記録する運転情報を変更し、事故時以外の契機においても運転情報を記録することにより用途毎に記録装置を設置することなく、運転情報の記録が行うことができる。
なお、本実施形態では、運転記録装置10は車内ネットワーク20から運転情報を取得するものであったが、各種センサにより運転情報を取得するものであっても良い。
