Inordertoimprovetherobustnessofthecontrolstrategyanddrivethemotoref-ficiency， as even degree of freedom dynamic model of a distributed drive electric vehicle is established firstly.Then based on the robust control theory， a stability controller with states estimation is designed based on H ∞ robust control.Using the characteristics of each wheel can be controlled independently of distributed drive electric vehicle， combining differential braking with differential drive， a torque distribution control strategy based on direct yaw moment is proposed.A numerical simulation was implemented for atypical condition of lane changing.The results show that the lateral stability is improved under lateral stability con-trol strategy with torque distribution control， and the wheel slip ratios is guaranteed in the lower range.
