基于单片机的导航智能车设计

Design of Navigation Intelligent Vehicle Based on Microcontroller

设计了一款以MC9S12XS128单片机为系统控制器的导航智能车,采用传感器采集道路信息,利用单片机的信息处理能力寻找小车与自动寻迹路径线之间的误差数据,再通过PID策略和PWM技术自动控制小车舵机的偏转角度和电机转速的参数,使得智能车能自动检测和跟踪道路寻迹线,从而实现智能车的自动导航。

This paper designs a navigation intelligent vehicle with MC9S12XS128 microcontroller as the system controller for the key technology of intelligent transportation systems.It uses sensors to collect information on the road,uses the information processing ability of the microcontroller to find error data between the car and the automatic tracking path line,and then uses PID strategy and PWM technology to automatically control the deflection angle and motor speed of the car servo,allowing the intelligent vehicle to automatically detect and track the road tracking line,thereby achieving automatic navigation of the intelligent vehicle.
