Adaptive Cruise Control Design Based on Fuzzy-PID

Adaptive cruise control (ACC) system is a Driver assistant system, which can provide safe and comfortable driving. Based on the analysis of ACC system, a parameter self-tuning fuzzy-PID algorithm is developed to design the ACC control strategy. According to the traffic condition, the parameters of PID controller are adapted on-line by fuzzy rule. The simulation results show that the parameter self- tuning fuzzy-PID controller integrates the advantages of PID controller and fuzzy controller. It improves driving safety of ACC, behaves higher speed of system response; performs smaller fluctuations and provides more comfortable traveling.
