PROBLEM TO BE SOLVED: To provide a lateral turning detection device for a vehicle which can detect lateral turning of a vehicle which is slowly rotated to such an extent that cannot be detected by a roll angular velocity sensor while suppressing increase in the number of components.SOLUTION: A lateral turning detection device has detection means 11 which is provided on a vehicle 1 and detects a detected object existing on a lateral side of the vehicle 1, and control means 20 which determines lateral turning of the vehicle 1 based on a detection result of the detection means 11. The control means 20 calculates an approach degree of the detected object based on an area ratio of a range in which existence of the detected object is detected to the whole range of a detection area of the detection means 11, and determines lateral turning of the vehicle 1 based on the approach degree. Consequently, lateral turning of the vehicle 1 can be detected even in the case of a low speed rotation of such an extent that cannot be detected by a roll angular velocity sensor in the prior art. Further, even if the vehicle 1 comprises a device or the like which detects the detected object which approaches from a lateral side and expands an air bag or the like, lateral turning of the vehicle 1 can be determined without addition of a new sensor and so on.SELECTED DRAWING: Figure 3
【課題】部品数の増加を抑えつつ、従来のロール角速度センサでは検知できない程度にゆっくりと回転する車両の横転を検出することができる車両用横転検出装置を提供する。【解決手段】車両1に設けられ車両1の側方に存在する被検知体を検知する検知手段11と、検知手段11の検知結果に基づき車両1の横転の判定をする制御手段20と、を有し、制御手段20は、検知手段11の検知領域の全範囲に対する被検知体の存在が検知される範囲の面積比に基づいて被検知体の接近度を演算し、前記接近度に基づいて車両1の横転を判定する。これにより、従来技術のロール角速度センサでは検出することができない程度の低速回転であっても、車両1の横転を検知することができる。また、側方から接近する被検知体を検知してエアバッグ等を展開させる装置等を備えている車両1であれば、新たなセンサ等を追加することなく、車両1の横転を判定することができる。【選択図】図3
