To acquire behavior information which follows a vehicle coordinate system with high accuracy by using a measurement device attached to a lean vehicle.SOLUTION: A behavior information estimation method estimates behavior information of a vehicle by using a three-axis acceleration sensor attached to the vehicle which can travel in an inclined state and is provided with a stand member for causing the vehicle to autonomously get still in an inclined state. The behavior information estimation method includes: a still measurement value acquisition step for acquiring an acceleration measurement value by the three-axis acceleration sensor in two states of an upright still state in which the vehicle is upright and still and an inclined still state in which the stand member is used to cause the vehicle to be inclined and still; and a behavior estimation step for converting the acceleration measurement value of the three-axis acceleration sensor in a traveling state of the vehicle into a value following a vehicle coordinate system regulated in advance to the vehicle on the basis of acceleration measurement values of the upright still state and the inclined still state.SELECTED DRAWING: Figure 3

    【課題】リーン乗物に対し取り付けられた計測装置を用いて、乗物座標系に従う挙動情報を精度良く取得する。【解決手段】挙動情報推定方法は、傾斜状態で走行可能でかつ、傾斜状態で乗物を自立静止するためのスタンド部材を備える乗物に対して取り付けられる3軸加速度センサを用いて、乗物の挙動情報を推定する挙動情報推定方法であって、乗物が直立したまま静止した直立静止状態と、スタンド部材が用いられて乗物が傾斜したまま静止した傾斜静止状態の2つの状態において、3軸加速度センサにより加速度計測値を取得する静止計測値取得工程と、直立静止状態及び傾斜静止状態の加速度計測値に基づいて、乗物の走行状態における3軸加速度センサの加速度計測値を、乗物に対して予め規定される乗物座標系に従う値に変換して挙動情報を推定する挙動推定工程と、を有する。【選択図】図3
