PROBLEM TO BE SOLVED: To provide a vehicle overturn detector capable of accurately detecting the occurrence of a vehicle overturn.SOLUTION: A vehicle overturn detector 1 comprises: a right acceleration sensor 2; a left acceleration sensor 3; and an overturn detection ECU 4. The overturn detection ECU 4 has a vertical velocity calculation unit 41; an overturn-angular-velocity calculation unit 42; and an overturn determination unit 43. The right acceleration sensor 2 detects an acceleration in the vehicle vertical direction on a right side of a vehicle. The left acceleration sensor 3 detects an acceleration in the vehicle vertical direction on a left side of the vehicle. The vertical velocity calculation unit 41 calculates values of velocities in the vehicle vertical direction on the right side of the vehicle and the left side of the vehicle. The overturn-angular-velocity calculation unit 42 calculates a value of an overturn angular velocity of the vehicle on the basis of a difference between a velocity in the vehicle vertical direction on the right side of the vehicle and a velocity in the vehicle vertical direction on the left side of the vehicle. The overturn determination unit 43 determines that an overturn has occurred to the vehicle when the calculated value of the overturn angular velocity becomes not smaller than a predetermined overturn determination threshold.SELECTED DRAWING: Figure 2

    【課題】車両の横転発生を正確に検出可能な車両横転検出装置を提供する。【解決手段】車両横転検出装置1は、右加速度センサ2と、左加速度センサ3と、横転検出ECU4とを備えている。横転検出ECU4は、上下速度算出部41と、横転角速度算出部42と、横転判定部43とを有して構成される。右加速度センサ2は、車両右側における車両上下方向の加速度を検出する。左加速度センサ3は、車両左側における車両上下方向の加速度を検出する。上下速度算出部41は、車両右側及び左側における車両上下方向の速度の値を算出する。横転角速度算出部42は、車両右側における車両上下方向の速度と車両左側における車両上下方向の速度との差に基づいて、車両の横転角速度の値を算出する。横転判定部43は、算出された横転角速度の値が所定の横転判定閾値以上になった場合に車両に横転が発生したものと判定する。【選択図】図2
