The velocity center theorem of a spinning mobile object and its application to the vehicles

Abstract

In this paper, focus on the mathematical physical theorem of spinning mobile objects, and introduce its application to the vehicles. By using this theorem, and considering the velocity center point CV of the rotating moving object and the turning center point CT of the representative point of the object separately, it will be able to explain various vehicles motion with one simple concept. In addition, it will be possible to clearly explain that the intersection point of the wheels axes of an automobile does not necessarily become the turning center point. This concept can also be applied to improving the driving stability of vehicles and to making quick steering decisions in autonomous driving. Since this theorem can be widely applied to various mobile objects, it is expected to be applied to new fields other than vehicle using wheels.
