Abstract
This paper presents vehicle stability analysis for a nonlinear vehicle model based on phase plane behavior theorem. Vehicle models under pure lateral slip, constant velocity, and constant front steer were developed. Four-wheel, two-track vehicle model was evolved from the bicycle model and were extended to include vehicle roll dynamics. For improving the stability and rollover prevention, then the height of center gravity (CG) is the important parameter must be taken into account. Through the phase plane behavior, the stability zone and instability zone of the vehicle are completely determined. For illustrating the effect of CG height on vehicle stability, extensive simulations with different CG heights are created. Finally, the analysis results would be applied to design the real model or mobile rack for enhancing the stability of the system.
