摘要
基于某搭载定速巡航系统的在研车辆,对巡航控制系统的结构及功能进行了梳理,通过对PID控制器的原理分析,建立了巡航系统的控制器算法,确定了控制器的关键参数。经过实车道路标定与试验,结果表明,该系统具有较好的精度,响应速度快,系统工作稳定,能够满足汽车巡航系统实际使用要求。
Basing on the automobile with a cruise control system, the paper analyzes the struc- ture and functions of the cruise control system. A controller algorithm for the cruise control system is established according to the analysis to the principle of the PID controller. The key parameters of the controller are set later. After calibration and real road test on the vehicle, the results show that the system has better control accuracy and fast response, and is able to stably work to satisfy the actual needs of the automobile cruise control system.
