Abstract
Vehicle parameters and operation conditions play a critical role in vehicular handling and stability. This study aimed to evaluate vehicle stability based on cornering tire stiffness integrated with vehicle parameters. A passenger vehicle is considered in which a two-state linear bicycle model is developed in the Matlab/Simulink. The effect of the vehicle parameters on lateral vehicle stability has been investigated and analyzed. The investigated parameters included CG longitudinal position, wheelbase, and tire cornering stiffness. Furthermore, the effects of load variation and vehicle speed were addressed. Based on a Fishhook steering maneuver, the lateral stability criteria represented in lateral acceleration, yaw rate, vehicle sideslip angle, tire sideslip angles, and the lateral tire force were analyzed. The results demonstrated that the parameters that affect the lateral vehicle stability the most are the cornering stiffness coefficient and the CG longitudinal location. The findings also indicated a positive correlation between vehicle properties and lateral handling and stability.

Summary
Conflict and Sensitivity Analysis of Vehicular Stability Using a Two-State Linear Bicycle Model. In another study [15], computer simulation analyses were presented based on a bicycle model to demonstrate the influence of tire characteristics on the handling and stability trends under normal and extreme maneuvering conditions. Most of the conducted studies have mainly focused on the vehicle parameters’ effect, including the vehicle inertial properties on the vehicular stability and its sensitivity to each parameter, while others were only limited to the investigation of the tire characteristics’ influences on the lateral vehicle dynamics. Δf donates for the front wheel steering angle, whereas a and b are the distances from the vehicle center of gravity to the front and rear axles, respectively In this investigation, the vehicular stability sensitivity analysis is conducted based on a bicycle model as described above. At 15 m/ s driving speed, the time-domain sideslip angles are plotted to illustrate the effect of the high and low tire cornering stiffness cases. e results indicated a significant increase in the sideslip with low cornering stiffness, especially at high
