As a type of distributed propulsion technology for new energy vehicles in recent future, in-wheel motorized four-wheel drive systems are increasingly seen in small sized battery energy stored and plug-in hybrid electric vehicles. For integration of the steer and traction controls the vehicle dynamics model is developed in Matlab/Simulink environment, in which the electric vehicle is simplified to be the symmetric half model of two degrees of freedom and the terrain mechanics model counting for side adhesion effect is adopted. Feedforward regulation and feedback correction control algorithms are applied and the vehicle steering angle, drive velocity, yaw rate and sideslip angle are treated as input variables in the control system. Both numerical simulations and experiments are performed for validation of the present method. It is demonstrated by comparison of the test results with the numerical predictions that the present control strategy is fairly good in efficiency for improving handling stability of the in-wheel motorized electric vehicles.
