Simulat ions w ere done under some typical operating conditions. T hen, the tract ion saddle parameters w ere debugged and w ell extract ed, and the system stabilit y w as investigated under the inf luence of t hese paramet ers, which provided ref erence for the desig ner . T he changes of driving conditions and parameters of the traction saddle could cause body ro
