摘　　要：分析了电子节气门系统的构成,将电子节气门系统软、硬件集成到了自行开发的基于16位单片机的发动机控制系统中,对控制参数进行了标定,利用变参数PID策略实现了节气门系统的位置控制,构建了电子节气门系统在发动机控制系统中的应用框架,为通过对发动机进气量进行智能化的控制从而提高其动力性、经济性、排放性打下了基础。The system structure of electronical throttle control（ETC） system and its software were described. The control method used in the system was PID arithmetic. The application structure of ETC was also constructed based on a 16-bit microcontroller. On the base of the ETC system, the intelligent control of engine＇s intake rate of air could be achieved. The system will benefit the engine in fuel consumption, power performance and emission.
