Abstract: In the design of the smart car system，the performance of smart car is directly determined by steering control.And the deflection continuity of the front wheels can’t be achieved ideally by the ordinary PID control algorithm.Thus，fuzzy control algorithm is put forward through the continuous exploration.In addition，at the level of hardware，dual steering gears are introduced to control every steering angle of the front wheels separately and continuously，with the view of an effective solution for the conflict between the rapidity and steady-state error of the system.A large number of experimental results prove that such method can significantly improve the performance of smart car system.
