摘 要: 当前各国对混合动力汽车发动机节能控制器的研究尚不健全,所研究出的产品稳定性较差、节能效果不佳。因此,设计兼顾高稳定性和高节能效果的混合动力汽车发动机节能控制器。该节能控制器的X186单片微控制器利用PID控制,对混合动力汽车发动机转速和行驶指令等信号进行实时监管,并经由信号二次处理电路进行转速信号再处理,降低发动机转速对混合动力汽车的能耗。由X186单片微控制器和信号二次处理电路获取到的节能控制信号,传输到输出控制电路进行汇总和解析,最终输出最优节能方案。控制器的实现部分给出了其功能图,以及控制器采用PID控制算法对发动机进行节能控制的过程。实验结果表明,所设计混合动力汽车发动机节能控制器的节能控制效果较为明显,并具有较高的稳定性。

Abstract: The research on engine energy?saving controller of hybrid power automobile is not perfect in various countries, which has caused poor stability of the researched products and poor energy?saving effect. Therefore, the engine energy?saving controller with high stability and high energy?saving effect for hybrid power automobile are considered. X186 single chip microcontroller of the energy?saving controller is controlled by PID to mornitor the engine speed and driving instruction signals of the hybrid power vehicle in real time. The signal secondary processing circuit is used to reprocess speed signal to reduce energy consumption of hybrid power automobile caused by engine speed. The energy?saving control signals acquired by X186 single chip microcontroller and the signal secondary processing circuit are transmitted to the output control circuit for the summary and analysis to output an optimal energy?saving solution finally. The functional diagram and the process of engine energy?saving control adopting PID control algorithm are given in the Controller Paragraph. The experiment result shows that the energy?saving control effect of the engine energy?saving controller for hybrid power automobiles is more obvious, and has high stability.
