PROBLEM TO BE SOLVED: To appropriately record various data to be acquired from a camera, sensor and the like attached to a vehicle in a recording device.SOLUTION: In an air bag ECU 10, a buffer unit 12 is configured to acquire data as to travelling of an own vehicle, and a recording control unit 13 is configured to, when an indicator indicative of impact detected by collision sensing sensors 21a-1 to 21c-2 sensing the impact upon collision of the own vehicle with other vehicle is equal to or greater than a record determination threshold, cause a recording unit 27 to record data buffered in the buffer unit 12. A collision possibility determination unit 14 is configured to, when a collision possibility between the other vehicle and the own vehicle output by a monitor sensor 25 outputting the collision possibility between the other vehicle and the own vehicle and a collision predicted location of the own vehicle with the other vehicle is equal to or greater than a prescribed value, change the record determination threshold in accordance with a location relation between the collision predicted location of the own vehicle with the other vehicle and the collision sensing sensors 21a-1 to 21c-2.SELECTED DRAWING: Figure 1
【課題】車両に取り付けられたカメラやセンサ等から取得される各種データを記録装置に適切に記録する。【解決手段】エアバッグECU10において、バッファ部12は、自車の走行に係るデータを取得する。記録制御部13は、自車と他車との衝突の際の衝撃を検知する衝突検知センサ21a−1〜21c−2により検知された衝撃を示す指標が記録判定閾値以上である場合、バッファ部12にバッファリングされているデータを記録部27へ記録させる。衝突可能性判定部14は、他車と自車との衝突可能性及び自車における他車との衝突予測位置を出力する監視センサ25により出力された他車と自車との衝突可能性が所定値以上である際に、自車における他車との衝突予測位置と衝突検知センサ21a−1〜21c−2との位置関係に応じて記録判定閾値を変更する。【選択図】図1
