| Abstract: | After analyzing the basic principle and structure traits of Auto Cruise Control System(CCS) and defining input signals and output signals,A CCS simulant equipment was built up,We brought forward a kind of new control scheme which is that Dual closed-loop controlling method of auto speed and throttle threshold is adopted and controlling arithmetic is parameter adaptive PI.The controller ceaselessly adjusts proportion and integral parameters intelligently so that the controlling effect is improved.By analysis of experimental results,it is confirmed that the cruise control system designed is rational and practical.It will play a good part in extensive application of Chinese automobile CCS in the future. |
