| 摘 要： | 针对单轴并联式(ISG)混合动力系统中能量回收效率低等不足,设计了一套含双离合器的总成结构方案,并采用较大功率的电动机.根据汽车动力学理论计算了车辆在中国典型城市等多种工况下的需求动力,对新方案的动力和传动进行了稳态工况的建模和仿真,仿真及试验结果表明,新方案的动力性可以实现无转矩波动的状态切换过程,改善了状态切换过程中动力传递的平顺性,缩短工况过渡的时间(从8s缩短剑4s),燃油经济性和排放性能也有一定的提高.

| Abstract: | For solving the problem that the ISG single-axis parallel hybrid energy recovery system is low efficiency, a structure with double-clutch and high power electric motor was designed. According to the theoretical of vehicle dynamics, the power demand in driving cycle for typical cities in China was calculated. Base on the stable conditions, simulation of the power and transmission conditions of the new power system was carried out, test results showed that the power and economy could achieved state switching process without torque ripple, and the smoothness of power delivery was improved, the time of transition conditions was shorten (reduced from 8 s to 4 s), fuel economy and emission performance also were improved. |
