| Abstract(E) | This paper investigates the dynamic equilibrium conditions required for a three-wheeled personal mobility vehicle (PMV) with an inward-tilting mechanism to achieve hands-free straight-line motion on slanted roads. The analysis compares the force balance of four-wheeled passenger cars, motorcycles, and tilting PMVs, revealing that the tilting PMV behaves analogously to a motorcycle—tilting slightly uphill while maintaining straight-line stability through camberthrust-induced lateral forces. Furthermore, it is shown that steering moments caused by load reaction forces can be neutralized by appropriately matching the kingpin angle, kingpin offset, and caster angle to the tire crown radius. These findings establish design requirements that enable a PMV to maintain hands-free straight-line travel even on slanted surfaces. |
