摘　　要：文中介绍一种基于电磁传感器路径识别的智能车控制系统,系统采用Freescale16位单片机MC9S12XS128为核心控制器,利用4个电磁传感器构成的传感器阵列采集路面信息,单片机获得传感器采集的路面信息和车速信息后控制智能车的舵机转向,同时对直流电机进行调速,从而实现智能车沿给定的赛道快速平稳的行驶。实验证明:系统设计可靠,智能车运行良好。A smart car control system based on the electromagnetic sensors was introduced.The system employs Freescale XS series 16 bit MCU MC9S12XS128 as its main controller and an array of electromagnetic sensors for recognizing the path information. MC9S12XS128 energizes the server to steer and control the speed of the DC electric motor according to the analysis of the path and speed information from sensors.Consequently, this intelligent vehicle can track the black- guide-line automatically and move forward following the line quickly and smoothly.Experimental results show that the design of system is reliable and the smart car works well.
