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 8-th 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 and ??-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.

In this paper, dynamic performance of 4WD/4WS Electric-driven vehicles is investigated. A coupled dynamic model is introduced for longitudinal, lateral and yawing motion of 4WD/4WS vehicles. Based on the coupled model, dynamic performance is analyzed for steady-state steering, acceleration steering and brake steering, respectively. These non steady-state cornering analysis is important for non-paved road maneuvering, trajectory projection for armored vehicle and future AVCS(Advanced Vehicle Control System) technology. Simulation results are obtained based on a simulink module for the introduced model.<br/>
