In this study, a simulation tool is developed in order to investigate non steady-state cornering performance of 4WD/4WS vehicles. The 4WD/4WS vehicles are modeled as a 8th order dynamic system which includes complex non-linear vehicle dynamics and tire models. The vehicle models are constructed into a simulation tool and are utilized for analyzing cornering performance such as combined braking and cornering, cornering on the icy road the μ-split braking. The whole process is done with the simulation tool which consists of a number of subsystems with modular approach and offers graphic environment. Simulation results show that this tool is useful and cost effective in the dynamic analysis of the combustion-engine vehicles as well as electrically driven vehicles.
