To provide a vehicle seat that reduces occupant sickness by reducing an acceleration generated by the occupant.SOLUTION: From an image pickup information including a travel path information acquired by an image pickup camera, a predicted acceleration change amount, which is a change amount of an acceleration generated by a control unit on an occupant, is calculated (step S120). When it is determined that the amount is within a predetermined sickness determination threshold range (step S130), a seating surface on which the occupant is seated is tilted to cause the occupant to accelerate by controlling a rotation speed of a motor. At this time, by inclining the seat surface at a speed and direction in which the change amount of the acceleration decreases, the change amount of the acceleration felt by the occupant is reduced to a range that is not included in the predetermined sickness determination threshold range. As a result, a possibility of occupant sickness can be reduced.SELECTED DRAWING: Figure 4
【課題】乗員に生じる加速度を低減させることで乗員の酔いを軽減する車両用シートを提供すること。【解決手段】撮像カメラが取得した走行路情報を含む撮像情報から、制御ユニットが乗員に生じる加速度の変化量である予測加速度変化量を算出し(ステップS120)、予め定められた酔い判定閾値範囲内に含まれていると判定した場合には(ステップS130)、モータの回転速度を制御することで乗員が着座した座面を傾斜させて乗員に加速度を生じさせる。このとき、加速度の変化量が減少する速度及び方向で座面を傾斜することで、乗員が感じる加速度の変化量を予め定められた酔い判定閾値範囲に含まれない範囲まで低減することで、乗員の酔いが発生する可能性を未然に低減することができる。【選択図】図4
