Qualitative analysis of the methods of improving the controllability and stability of wheeled vehicles

The development of active safety systems of vehicles is very important since they enhance stability and controllability. In this paper, the qualitative study of the stability and controllability of wheeled vehicles is performed and principal solutions to the motion control problem that increase the course and trajectory stability of vehicles are analyzed. Analytical methods are used to study the motion stability of wheeled vehicles. It has been found that the PID controller providing the dynamic stabilization of a wheeled vehicle in its rectilinear or curvilinear motion increases the motion stability margin. The results of research can be used by automotive industry enterprises to design and produce two-axle wheeled vehicles of various classes and purposes, as well as by the organizations that develop control systems for wheeled transport.
