PROBLEM TO BE SOLVED: To accurately detect acceleration using a three-axis acceleration sensor.SOLUTION: An acceleration processing device 10 includes a three-axis acceleration sensor 22 to be attached to a vehicle 12, and, with a noise removal unit 44, passes a signal value S acquired from the three-axis acceleration sensor 22 through a temporary delay filter of a predetermined time constant, thereby calculating and storing a temporary delay value L. The acceleration processing device 10, with a stationary component removal unit 46, calculates a present variation Fon the basis of the present temporary delay value L and a temporary delay value Lbefore a prescribed time, and, with a composite value calculation unit 48, calculates an acceleration composite value A from the present variation F.SELECTED DRAWING: Figure 2

    【課題】3軸加速度センサを用いて加速度を一層精度よく検知する。【解決手段】加速度処理装置10は、車両12に取り付けられる3軸加速度センサ22を有し、ノイズ除去部44により、3軸加速度センサ22から取得した信号値Sを、所定の時定数の一時遅れフィルタに通して一時遅れ値Lを算出及び記憶する。また、加速度処理装置10は、定常成分除去部46において今回の一時遅れ値Lと、所定時間前の一時遅れ値Lbeforeとに基づき今回の変動値Fnを算出し、さらに合成値算出部48により今回の変動値Fnから加速度合成値Aを算出する。【選択図】図2
