摘要： 为以更低的制造成本，实现轻度混合动力传动系统节省燃油和降低排放的控制效果，以新型回流式无级自动变速传动系统为基础，利用其大的速比变化范围、较低转速时传动效率高和承载能力大的特点，克服轻/微度混合动力传动系统不具备纯电动驱动工况的局限性，通过采用新的传动方式和匹配控制策略，开展基于大速比变化范围的混合动力传动系统匹配设计理论与控制方法的研究。试验结果表明，超轻度混合动力汽车节油率可达到13.02%，其中回流式无级变速器的节油贡献率为1.88%。

Abstract: In order to reduce production cost, improve control effect of saving fuel and reducing emission, a new super-mild hybrid transmission system is developed to over the limitation of the existing mild hybrid electric vehicle (HEV) which has not the working condition as the pure electric drive. The new one is based on continuously variable transmission (CVT) with reflux power, which features wide speed ratio range, high transmission efficiency and big loading ability. Through adoption of the new transmission mode and match control strategy, the match design theory and control method of hybrid transmission system based on large speed range are researched. The test results show that the super-mild HEV saves fuel by 13.02%, in which 1.88% is contributed by the continuously variable transmission (CVT) with reflux power.

Key words: Continuously variable transmission, Control strategy, Hybrid transmission, Simulation analysis
