PROBLEM TO BE SOLVED: To provide an inexpensive vehicle body vibration control device capable of obtaining a vibration control effect of a vehicle body.SOLUTION: The vehicle body vibration control device comprises vehicle body vibration control device swiveling detection means 4 and 12; suspension geometry constant calculating means 5 for changing changes the size of a suspension geometry constant which is displacement characteristics of a tire based on a suspension geometry according to a swiveling state of a vehicle, and differing the suspension geometry constant in the swiveling state and a straight advance state; vertical force calculating means 2 for calculating vertical force applied on the tire from a road surface on the basis od wheel speed changes, by using the suspension geometry constant; on-spring behavior estimating means 7 for estimating a behavior of a vehicle body 100 on the basis of the vertical force; and torque command calculating means 12 for calculating torque outputted by a prime mover 106 from a required braking/driving torque and a correction torque on the basis of the behavior information of a vehicle body.

    【課題】 安価で、車体の制振効果を得ることが可能な車体車体制振制御装置を提供する。【解決手段】車体制振制御装置は、旋回検出手段4、12と、サスペンションジオメトリに基づくタイヤの変位特性であるサスペンションジオメトリ定数の大きさを車両の旋回状況に応じて変更し、旋回状況と直進状況とでサスペンションジオメトリ定数を異ならせるサスジオ定数算出手段5と、サスペンションジオメトリ定数を用いて、車輪速変動に基づき路面からタイヤに加わる上下力を算出する上下力算出手段2と、上下力に基づいて車体100の挙動を推定するバネ上挙動推定手段7と、車体の挙動情報に基づき車体の振動を抑えるように要求制駆動トルクと補正トルクとから原動機106が出力するトルクを算出するトルク指令値算出手段12とを備える。【選択図】図3
