Rider's operation of a motorcycle running straight at low speed

Abstract

To maintain the stability of a motorcycle running straight, the rider steers the handlebars with his hands and leans his body to the right or left on the seat in dead time (time lag) to the motion of the disturbances of the motorcycle's frame. Since these three movements relate to one another and it is difficult to analyze the motion of the motorcycle-rider system, we treat the motorcycle and the rider as one rigid body. In this report, we studied the conditions necessary for stability and the rider's operation and control of the motorcycle running straight at low speed using the equation of motion, in which the movement of the center of gravity of the rider to the right or left, the reaction of the motorcycle to the rider's movement and the moment of inertia of the rider are considered.
