Study on the influence of the arrangement of battery pack on the steering characteristics of electric vehicle

Abstract

This paper established the three degree of freedom mathematical model,based on the two degree of freedom linear model with two wheel steering.Then the dynamics differential equation is obtained. With a step input of the front wheel, observing and analyzing the yaw rate response and the side slip angle response in the whole process based on MATLAB/Simulink. Finally, by changing the position of the battery pack to transform the location of the gravity center of the whole vehicle, analyzing the impact on the electric vehicle’s steering characteristic while the location of battery pack changed.
