摘要
研究装有AMT的越野车的巡航控制技术.分析了巡航系统的功能,设计了巡航控制程序的执行流程.采用模糊PID控制策略,建立了控制参数KP,KI与KD与速度偏差E和偏差变化率Ec的二元函数关系;在大量实验和熟练驾驶员经验的基础上,建立了系统的模糊控制规则表.在台架上完成了巡航的进入与退出,加、减速功能及恒速控制功能的实验,并进行了模糊PID与普通PID的对比控制实验.实验结果表明,所开发的基于AMT越野车的巡航控制系统具有良好的性能.
Investigates the cruise control for an off-road vehicle with automated mechanical transmission.The cruise control system（CCS） functions are analyzed and the program flow chart of the CCS developed.A fuzzy PID control strategy is developed for the CCS.Relations between the KP,KI,KD and speed error E and error change rate Ec are established.Based on a large number of tests and the experiences of skilled drivers,fuzzy control rules are developed.Experiments of entry and exit of the cruise control system and engine responses at different speed errors are conducted on a test bench.Also,comparison experiments between the fuzzy PID and PID are accomplished.Experiment results showed that the developed cruise control system has a good performance.
