基于电磁引导的智能车电控系统设计

摘要

为改变驾驶车“人一车一路”闭环控制方式，确保车辆安全、可靠的行驶，采用单片机MC9S12XS128为核心控制芯片，利用电磁传感器为路径判断，速度传感器为闭环控制，设计了一种基于电磁引导的智能车控制系统。重点介绍系统的工作原理，硬件电路的设计及软件的实现，主要包括传感器模块、电源模块、电机驱动模块、控制算法等。该智能车系统经实际调试与运行的结果表明，小车运行性能优良，满足了设计要求。%In order to change ＂Person-Car-Road＂ closed loop control way, make sure the vehicle drive safe and reliable. The electromagnetic guided intelligent vehicle electronic control system is designed by using SCM MC9S12XS128 as the control core, using electromagnetic sensor as path judgment and speed sensor as the closed loop control. The working principle, hardware circuit and software realization are introduced. It mainly includes sensor module, power module, motor drive module and control algorithm. By actual operation, the results show that the vehicle runs fine and meets design requirements.
