摘要
基于串联混合动力汽车建立了电传动系统各关键部件的数学模型,并分析了其工作特性;进而以燃油经济性和电池寿命为控制目标对电传动系统的控制策略进行了研究与设计;结合城市循环工况US06,在MATLAB/Simulink环境中进行了系统仿真,结果表明所设计的控制策略合理有效,可以使电传动系统工作在效率较优状态,在保证动力性的同时实现良好的经济性目标。
Mathematic models of electric transmission system pivotal components are established based on series hybrid vehicle and working characteristics are analyzed.A control strategy of electric transmission is proposed for purposes of improving economical efficiency and maintaining battery life.System simulation is made in MATLAB/Simulink circumstance combining the cycling condition US06,which results show that strategy presented,making system working in high efficiency state,is effective to realize both dynamic property and the favorable economy control target.
