摘要
公路限速系统是一种可以对行驶在限速路段中的车辆速度进行控制的综合交通安全系统,本文运用巡航技术对公路限速系统中的车载部分进行设计。文中利用M A T L A B工具建立了汽油机汽车发动机的仿真模型,并用B P神经网络自适应P I D设计了控制器,通过仿真验证了该车载系统的有效性。
The speed limit system in highway is a comprehensive transportantion safety system, which are used to control speed of vehicle in specific roadway. In this article, the automotive onboard conlroller .as the important part of speed limit system is designed. The simulation model of motor engine is established based on Matlab tools. Its controller is realized on neural BP network adaptive PID. The results show that this automotive onboard system is efficient.
