| Abstract: | A 3-DOF full vehicle model was established using MATLAB/Simulink to examine the influence of road geometry parameters on vehicle handling stability.The dynamic responses of vehicle in different road superelevations,longitudinal grades,and longitudinal/transverse grade combinations were discussed by numerical simulation.A further sensitive analysis was also conducted to evaluate the influence of road geometry parameter on vehicle handling stability at different vehicle speeds and front wheel steering angle i... |
