With the development of automobile industry in China, people pay more attention to electric vehicles. The safe operation of the vehicle is related with the stability. The lateral stability of the electric vehicles is relevant with the steering characteristic. Though influenced by four tires' cornering stiffness and the suspension characteristics, the steering characteristic mainly depends on the longitudinal posi-tion of the center of gravity. The steering characteristic of electric vehicles has a great effect on steering control. The steering characteristic of electric vehicles has great influence on the ride comfort and the service life of the tire as well. The study of steering characteristics mainly focused on the influence of the wheels, suspension structure, suspension system and the control system and steering characteristics of four-wheel steering vehicles. Because the battery pack is very heavy, the position of the bat-tery pack directly influence the location of the center of gravity of the vehicle, and then affecting its steering characteristic greatly. Therefore, electric vehicles’ steering characteristic depends on the position of battery pack so much.
