In view of the control problem of electronic differential(ED)system in a hybrid electric vehicle with dual in-wheel-motor rear drive and considering the effects of axle load transfer, centripetal force and tire slip angle, a ED control strategy based on threshold control is proposed with the slip ratio of tire as control objective, and a simulation is conducted. The results show that the ED control system proposed can keep tire slip ratio within the optimum range, ensuring the stable driving of vehicle along preset direction either on straight road or curved one.
