Design Requirements for Personal Mobility Vehicle (PMV) with Inward Tilt Mechanism to Minimize Steering Disturbances Caused by Uneven Road Surface

The Personal Mobility Vehicle (PMV), which has an inward-tilting angle, turns with lateral force due to a large camber so it is necessary consider the movement of tire vertical load axis during turning. Although steering torque mechanisms are very different from those automobiles, there not many studies PMVs. In this paper, based on effects six components acting tires, method for setting specifications derived, including geometrical minimization moment disturbance reaction Automobile tires have significant ground angle when traveling rutted roads, but they do slanted roads because vehicle body tilts along road surface. On other hand, in PMVs, always keeps upright both and roads. Therefore, angles types We study straight running ability under such surface disturbances This can be remarkable strong point PMVs inward tilt mechanism. study, was proved that parameters derived uniquely by taking into consideration requirement zero (disturbance) around against at all internal angles.
