PROBLEM TO BE SOLVED: To provide a vehicle bank angle detection device in which a vehicle bank angle can accurately be detected even when turned while a rider's posture is displaced to one side in the lateral direction from the central line of a vehicle body.SOLUTION: A bank angle detection device 20 of a motorcycle includes bank angle estimation means 28 for estimating a moving body bank angle, and correction means 30 for estimating a vehicle body bank angle. The bank angle estimation means 28 estimates the moving body bank angle, a tilt of the moving body axis line, on the basis of a state of matching the centrifugal force acting on the moving body with the gravity acting on the moving body in turning. The correction means 30 corrects the moving body bank angle on the basis of the inertial force around the back and forth axial center acting on the vehicle body, and estimates the vehicle body bank angle, the tilt to the vertical line of the center of gravity of the vehicle body.SELECTED DRAWING: Figure 3
【課題】ライダーの姿勢が車体の中心線よりも左右方向一方にずれた状態で旋回した場合でも、乗物のバンク角を精度よく検出することができる乗物のバンク角検出装置を提供する。【解決手段】自動二輪車のバンク角検出装置20は、移動体バンク角を推定するバンク角推定手段28と、車体バンク角を推定する補正手段30とを備えている。バンク角推定手段28は、移動体に働く遠心力と旋回時に移動体に働く重力とが釣り合う状態に基づいて、移動体軸線の傾きである移動体バンク角を推定する。補正手段30は、車体に働く前後軸心周りの慣性力に基づいて、移動体バンク角を補正して、車体重心の鉛直線に対する傾きである車体バンク角を推定する。【選択図】図3
