PROBLEM TO BE SOLVED: To provide a collision determination device capable of preventing a contribution extent due to side slip from affecting a collision determination using lateral acceleration of a vehicle.SOLUTION: A collision determination device 12 comprises a left side sensor 20, a right side sensor 22, or a Y shaft G sensor 24 for outputting a signal according to lateral acceleration to a vehicle body lateral direction applied to an own vehicle; and a collision determination part 36 for performing a collision determination of a vehicle based on output signals of the sensors. The collision determination device further comprises: a side slip determination part 40 of a CPU 32 for determining whether or not the own vehicle side slips; and a correction part 42 of the CPU 32 for, when it is determined that, the own vehicle side slips by the side slip determination part 40, correcting the output signal of the left side sensor 20, the right side sensor 22, or the Y shaft G sensor 24 for solving zero point deviation of the lateral acceleration due to the side slip, in a period when lateral acceleration due to the side slip is applied to the vehicle.SELECTED DRAWING: Figure 1
【課題】車両の横加速度を用いた衝突判定に横滑りに起因する寄与分が影響するのを防ぐことが可能な衝突判定装置を提供する。【解決手段】衝突判定装置１２は、自車両に加わる車体左右方向への横加速度に応じた信号を出力する左サイドセンサ２０、右サイドセンサ２２、又はＹ軸Ｇセンサ２４と、それらのセンサの出力信号に基づいて車両の衝突判定を行う衝突判定部３６と、を備える。また、自車両が横滑りするか否かを判定するＣＰＵ３２の横滑り判定部４０と、横滑り判定部４０により自車両が横滑りすると判定された場合に、その横滑りによる横加速度が車両に加わる間、その横滑りに起因する横加速度のゼロ点ずれを解消すべく左サイドセンサ２０、右サイドセンサ２２、又はＹ軸Ｇセンサ２４の出力信号を補正するＣＰＵ３２の補正部４２と、を備える。【選択図】図１
