摘要
国内乘用车市场越来越成熟,消费者对驾乘的需求也在不断提高,诸如动力性、经济性、操控性、平顺性、耐久性、NVH特性等等,都是消费者所关注的事项。而在众多驾乘评价项目中,换挡平顺性是重点抱怨之一。随着自动挡车型的兴起,搭载AT/DCT/CVT/AMT变速器的传统燃油车占领了大部分市场份额,相较于搭载MT变速器的车辆换挡平顺性有了很大程度的改善。在众多类型的自动变速器中,AMT成本低廉且传递效率高,却因其换挡动力中断感明显而被各大主机厂冷落,成了小众类型。而近年来P2.5/P3/P4等混合动力构型汽车的发展,为换挡平顺性和经济性不能兼顾的问题提供了一个解决方案。本文针对基于AMT变速器技术基础拓展的P3构型,讨论驱动电机对AMT加速升挡过程中动力中断的补偿方法及补偿效果的评价方法,希望为主机厂后续的产品开发提供一些参考。
The domestic passenger car market is becoming more and more mature,and consumers’demand for driving is also increasing,such as power,economy,handling,smoothness,durability,NVH characteristics,etc.,which are all matters of concern to consumers.In many driving evaluation projects,shifting smoothness is one of the key complaints.With the rise of automatic transmission,traditional fuel vehicles equipped with at/DCT/CVT/AMT transmission occupy most of the market share,and the shift smoothness of vehicles equipped with MT transmission has been greatly improved.Among many types of automatic transmission,AMT has low cost and high transmission efficiency,but it has been ignored by major engine plants because of its obvious sense of power interruption in shifting,which has become a small type.In recent years,the development of p2.5/p3/p4 and other hybrid electric vehicles provides a solution to the problem that shift smoothness and economy cannot be considered.In this paper,aiming at P3 configuration based on AMT transmission technology,the compensation method of power interruption and the evaluation method of compensation effect of drive motor in the process of AMT acceleration upshift are discussed,hoping to provide some reference for the subsequent product development of the main engine plant.
