Personal Mobility Vehicle (PMV) which has an inward tilting angle according to the steering angle, turns mainly by the lateral force due to the tire camber angle. Although the steering torque characteristics are very different from those of automobiles, there are not many examples which studied the steering torque characteristics of PMV. In this study, the steering torque characteristics of PMV with inward tilting mechanism are organized and the characteristic requirements for the steering mechanism are discussed. Finally, additional centering torque proportional to provisional lateral acceleration is proposed to produce natural and controllable steering torque characteristics for PMV with inward tilting mechanism. Low road friction and oversteer conditions are also considered.
