Abstract

ABSTRACT
A14 Degrees Of Freedom vehicle handling dynamics model is presented and
implemented using MATLAB/SIMULINK software. The model is used to predict the
behavior of a golf car in different steering conditions. This work is focusing on the
vehicle heading modeling as a part of “implementation and control of an autonomous
car project” adopted by Autotronics Research Lab (ARL). The vehicle handling
related degrees of freedom are calculated. The vehicle yaw rate and lateral
acceleration for step and sinusoidal steering wheel excitation are computed to predict
the heading of the vehicle. The model results are verified against similar work
studying the steering and handling behavior of different cars. The results show good
agreement with the literature results.
