Abstract:This paper designs a fuzzy controller based on the smart car with the development platform of k60, which can make the car fit better to the center line of the track than the traditional PID control, and it is not easy to get out of the track. This paper introduces the software and hardware of the smart car, constructs a smart car platform, and then introduces the fuzzy controller designed in this paper. Finally, the correctness and effectiveness of the designed controller are obtained through MATLAB simulation and field smart car detection.

Keywords:Fuzzy Control Steering Control Path Tracking Smart Car
