In order to improve overall vehicle performance and decrease movement deviation caused by uncertainties from automobile chassis, a robust vehicle chassis model is built with steering system, suspension system and braking system. In the model, the length of the steering trapezoid arm, the bottom angle of trapezoid mechanism, inclination angle, caster, camber and toe-in are defined as controllable variables, and load, driving force, steering torque are defined as noise factors. The optimum objectives include the maximum turning angle error of steering mechanism, the maximum braking sideslip and the maximum swing angle of front wheel on bumpy road. Taguchi method is applied to solve the robust result for automobile chassis model. Compared that the variances of objective values are decreased with the same noise factors and the robustness of sub-systems of chassis is improved.
