Abstract
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.
