Design of Follow-Up Control in Auto-Tracking Smart Car System

Abstract:

Aiming the problems caused by the narrow path recognition range of auto-tracking smart cars, this paper proposes a follow-up control based on the Freescale K10 microcontroller. A laser detection sensor was used to percept the path information. And a follow-up steering servo was used to drive the laser detection sensor to track the road path and controlled by the PID algorithm. Moreover, the system combined Ziegler-Nichols method and trial-and-error method to tune the PID parameters. Experiments show that, the smart car with the follow-up control has a wider path recognition range, an improved driving path and a higher speed.
