Abstract
AbstractIn this paper, a mathematical model describing the vehicle dynamics is built based on a nonlinear tire model and vehicle dynamic model of longitudinal and lateral motion. The influence of two drivetrain layouts FWD and RWD on vehicle lateral dynamics are considered. The analysis is done in MATLAB/SIMULINK environment. The results confirm that the inertia and lateral forces generated at the tires when the vehicle is cornering depend on many different parameters, in which these forces have a proportional relationship with the vehicle velocity and steering angle. The greater the vehicle velocity and/or steering angle, the greater the inertia and lateral forces generated. Besides that, when cornering, the lateral forces of the tires and the inertia forces in the longitudinal and transversal directions of the FWD vehicle are greater than those of RWD vehicle.KeywordsLateral dynamicsDrivetrain layoutSimulationLateral forceInertia forceNon-linear tire model
