Improvement of Ride Comfort by Unsprung Negative Skyhook Damper Control Using In-Wheel Motors

インホイールモータを用いたばね下逆スカイフックダンパ制御による 乗り心地の研究

Vehicles equipped with in-wheel motors (IWMs) are capable of independent control of the driving force at each wheel. These vehicles can also control the motion of the sprung mass by driving force distribution. However, one disadvantage of IWMs is an increase in unsprung mass which causes uncomfortable ride. This research aimed to improve ride comfort through driving force control. As a result, a method was derived by analysis that reduced uncomfortable vibration by a control that applies unsprung velocity in the direction that enhances that velocity. Then the improvement effect on ride comfort and stability by this control was verified.インホイールモータ車は駆動により生じるサスペンション反力を利用することで,ばね上運動制御が可能である.本研究の目的は,路面外乱に対し乗員が感じる不快なばね上振動を,駆動力制御により低減することである.ばね下の運動情報のみを用いてばね上を制振させる制御法を提案する.
