To provide a vehicle, a vehicle motion state estimation device and a vehicle motion estimation method capable of estimating a state amount of bounce motion of a vehicle having nonlinear suspension characteristic with high accuracy.SOLUTION: A vehicle motion state estimation device in a vehicle in which wheels and a vehicle body are combined through a suspension includes: a bounce motion estimation part for estimating and outputting a state amount of bounce motion of the vehicle on the basis of travel state information of the vehicle; and a correction value estimation part for calculating a correction value for correcting an output of the bounce motion estimation part on the basis of an output of the bounce motion estimation part. In the vehicle motion state estimation device, the correction value estimation part considers a nonlinear characteristic of the suspension to calculate the correction value.SELECTED DRAWING: Figure 2

    【課題】非線形なサスペンション特性を有する車両のバウンス運動の状態量を高精度に推定できる車両、車両運動状態推定装置、および車両運動状態推定方法を提供する。【解決手段】車輪と車体がサスペンションを介して結合された車両における車両運動状態推定装置であって、車両の走行状態情報に基づいて車両のバウンス運動の状態量を推定し出力するバウンス運動推定部と、バウンス運動推定部の出力に基づいて、バウンス運動推定部の出力を補正する補正値を算出する補正値推定部を有し、補正値推定部はサスペンションの非線形特性を考慮して補正値を算出する車両運動状態推定装置。【選択図】図2
