Research and Teaching Interest

Distributed driving vehicle is different with conventional vehicle, which involves the yaw moment provided by independent electric motors on both sides. Based on that, the conventional handling stability theory could be broken because of the closed-looped handling dynamic system, so that the mobility and overall layout flexibility of the vehicle could be improved by decreasing static margin. We established relaxed static margin design principle, and carried out the vehicle closed-looped handling stability which is the key point during the process. Based on the purpose, the yaw moment provided by steering wheels swing and independent electric motors is defined as 1st and 2nd steer control surface, through studying the coupling action mechanism of double steer control surfaces to build a high-dimensional closed-looped vehicle handling dynamic model. Through revealing the variation law of system constitutive equation after the control law of second control surface is involved, study the instability mechanism of the closed-looped dynamic system. Based on these, obtain the relationship between vehicle static margin and vehicle closed-looped stable region, to provide the base of establishing vehicle relaxed static margin design principle. Apparently, the research could break the constraint of distributed driving vehicle design under conventional handling stability theory, to further improve the mobility and overall layout flexibility of the vehicle, to provide guidance for designing distributed driving special vehicle which has a greater mobility demand.
