基于AVR单片机的电子节气门实验控制系统研制

摘要

电子节气门是现代汽车发动机管理系统中的重要部件,也是汽车发动机教学仪器的组成核心.以ATmega128为主控芯片,以电子节气门为研究对象,基于PID控制算法,设计并实现了电子节气门实验控制系统.试验表明,该系统可以直观地展示节气门开度对踏板位置信号的响应,满足汽车发动机电子节气门教学仪器的使用要求.%Electronic throttle is an important part not only in modern automobile engine management system,but also in automobile engine teaching instrument.This paper develops the electronic throttle control experiment system with the ATmega128 as control core and DV-E5 type electronic throttle valve as object of study and based on PID control algorithm.The tests indicate that the response of throttle opening to the pedal position can be directly displayed in this system.It can satisfy the operating requirements of the auto-mobile engine teaching instrument.
