PROBLEM TO BE SOLVED: To provide a data recording system for a vehicle capable of suppressing a situation that when accident state data are recorded in a peripheral vehicle which travels in the periphery of an accident target vehicle at occurrence of an accident, highly necessary accident state data recorded in the peripheral vehicle are overwritten.SOLUTION: Each vehicle is configured to, when an accident occurs in an own vehicle, transmit a request signal to a center. The center is configured to, when receiving the request signal, specify a peripheral vehicle in the periphery of an accident vehicle on the basis of location information of each vehicle, and to transmit a command signal including an instruction to record data in a permission area between a permission area and an inhibition area of an in-vehicle storage part set for each vehicle to the peripheral vehicle. Each vehicle is configured to, when receiving the command signal, record data indicating a peripheral state of the vehicle as accident state data in the permission area of the in-vehicle storage part indicated by the command signal. Then, the center is configured to, when determining that necessity of the accident state data is high, change an area in which the accident state data are recorded of the in-vehicle storage part of the peripheral vehicle from the permission area to the inhibition area.SELECTED DRAWING: Figure 4

    【課題】事故発生時、事故の対象車両の周辺を走行等している周辺車両に事故状況データを記録させる場合に、周辺車両に記録された必要性の高い事故状況データが上書きされる事態を抑制することが可能な車両用データ記録システムを提供すること。【解決手段】各車両は、自車に事故が発生すると、要求信号をセンタに送信する。センタは、要求信号を受信すると、各車両の位置情報に基づき、事故車両の周辺の周辺車両を特定し、車両毎に設定される車載記憶部の許可領域と禁止領域のうちの許可領域にデータを記録する旨の指示を含む指令信号を周辺車両に送信する。各車両は、指令信号を受信すると、車両の周辺状況を示すデータを事故状況データとして指令信号で指示される車載記憶部の許可領域に記録する。そして、センタは、事故状況データの必要性が高いと判断すると、周辺車両の車載記憶部の事故状況データが記録される領域を許可領域から禁止領域に変更する。【選択図】図4
