基于导航系统的自动寻迹智能小车研究

摘要

提出了基于主动导航的自动寻迹智能车设计方案,通过设计主控芯片、驱动控制电路和导航系统等,建立主动寻迹模型,实时准确地对航向角和行驶路线进行控制,并完成了程序编译,搭建自动寻迹智能小车模型.道路试验结果表明,智能小车中心点偏移量在±0.30 m范围内,达到预期要求,可以依靠GPS定位数据实现基于主动导航的自动寻迹.%Based on active navigation, this paper proposed design proposal of automatic tracking intelligent car. the model of automatic tracking by designing master chip was established, with control circuit and navigation system that could control the real-time heading angle and driving routes accurately; and finally the control program were compiled and a model of automatic tracking car was established. The road test shows that the offset at the center of the intelligent car ranges within ±0.30 m, which meets the expected requirements. Therefore, the intelligent car can rely on GPS positioning data to achieve automatic tracking under the active navigation.
