As the primary performance of modern vehicles,it’s important to do some research on handing and stability,which not only affects ease of manipulation of vehicle driving,but also determines the vehicle’s driving safety. Handing and stability is known as “The lifeline of high-speed vehicles”.The general situation of multi-axis steering technique at home and abroad is introduced in this article,especially the research on handing and stability about multi-axis vehicle.The vehicle handing and stability is analyzed by simulation experiment through the establishment of linear multiple degrees of freedom mathematical and dynamic models.The results show the turning radius is effectively reduced by using multi-axis steering technique on heavy trucks,then the handing stability and safety is improved.
