弱电混合动力系统设计解决方案与控制策略研究

Mild Solution of Hybrid System Design and Control Strategy

介绍了一种具有启停功能的并联式混合动力系统的工作原理,首先给出汽车启停系统和并联式混合动力车实现思路并分析其在燃油经济性与排放性的优势,进而设计同时具有以上功能的弱电混合动力系统布置方式及结构方案。最后,根据汽车的各项功能结合实际情况规划出弱电混合动力系统的控制功能定义层,对在各种行驶状态下此系统的控制功能进行策略分析,结合结构方案与控制动力策略制作试验车,得出实验数据。

A parallel with the start-stop function of mild solution to hybrid systems is presented.First are given car start-stop system and the implement ideas of parallel hybrid,and its fuel economy and emissions of the advantages are analyzed,and then layout and structure of mild hybrid system simultaneously with the above mentioned functions are designed.Finally,according to the car＇s various functions with the actual situation,the control functions defined layer of a mild hybrid system is planned,strategic analysis is done for control functions in the system in various driving conditions,combined with the structure plan strategy for making power and control test vehicle,experimental data is obtained.
