Considering the inertia moment of control arm, wheel mass and its inertia moment about the longitudinal axis and tire damping and lateral deflection, a novel model based on a quarter car one with MacPherson suspension is established. This kinematic-dynamic model overcomes two weaknesses of the classical 2DOF model: it accounts for linkage geometry and lateral stiffness of tire. The displacement of the sprung mass and the tire dynamic load of proposed model, three-dimensional model established in the ADAMAS/View and the classical 2DOFs model are calculated and compared. It is found that the proposed model in this paper is closer to the three-dimensional model than classical 2DOFs model. This proposed model is validated by comparing with two kinematic parameters: camber angle and track width variation calculated in this model and three-dimensional model respectively. In addition, the PID and sky-hook on-off control algorithm are applied to the proposed model respectively and the control effects of two algorithms are compared.
