摘要
针对电子节气门的构造及其机械结构中存在的非线性问题,设计了基于PIC18F458的电子节气门控制系统。该系统利用PIC的A/D转换以及脉宽调制功能来控制节气门,实现了电子节气门的位置控制。试验结果表明,该电子节气门控制系统具有良好的跟随特性,提高了汽车的动力性、平稳性和经济性。
For the structure of electronic throttle and the nonlinearity existed in mechanical structure, the control system of electronic throttle based on PIC18F458 was designed. The position control of electronic throttle was realized through A/D conversion, which belonged to PIC, and PWM. The results show that the control system has better following characteristic, which improves dynamic, stability and fuel economy.
