PROBLEM TO BE SOLVED: To estimate ride comfort of an occupant in a vehicle by a simple structure.SOLUTION: An occupant state estimation device 100 obtains a vehicle behavior signal from a vehicle behavior sensor 10 that is fixed and set on a vehicle to detect movements of the vehicle and/or inclination of a vehicle body. The vehicle behavior signal includes vehicle behaviors indicating movements of the vehicle and/or inclination of the vehicle body. The occupant state estimation device obtains a gravity center movement control signal including movements of the gravity center of an occupant from a gravity center movement control sensor 20 that is configured to detect movements of the gravity center of at least one occupant in the vehicle. Then, for example, a fluctuation calculation part 101 calculates fluctuations on the basis of time-sequence data of differences between the vehicle behavior signal and the gravity center movement control signal, and a comfort/discomfort estimation part 102 estimates on the basis of the calculated fluctuations whether the occupant feels comfortable on the vehicle behaviors.SELECTED DRAWING: Figure 2
【課題】簡易な構成で、車両の乗員の乗り心地を推定する。【解決手段】乗員状態推定装置100は、車両に固定して設置された車両の動き及び/又は車体の傾きを検出する車両挙動センサ10から、車両の動き及び/又は車体の傾きを示す車両挙動を含む車両挙動信号を取得し、車両内の少なくとも1人の乗員の重心の動きを検出する重心制動センサ20から、乗員の重心の動きを含む重心制動信号を取得する。そして、例えば、ゆらぎ計算部101が、車両挙動信号及び重心制動信号の差分の時系列データに基づいてゆらぎを計算し、快適度・不快度推定部102が、計算されたゆらぎに基づいて、乗員が車両挙動に関して車両の乗り心地の良さを感じているか否かを推定する。【選択図】図2
