摘要
双离合器式自动变速器(DCT)为一种新型自动变速器,其既可实现单离合器接合起步,又可以双离合器联合起步。基于对两种起步方式的分析,结合DCT车辆起步过程的影响因素,论述了离合器控制策略的研究现状。考虑DCT车辆起步滑摩功和冲击度两项性能指标,综合起步时间、功率循环等因素,对两种起步方式进行了全面分析比较。
Dual clutch transmission(DCT),as a kind of new automatic transmission,can realize single- clutch engagement start and dual- clutch joint start. Based on the analysis of the above two start modes,coupled with the influencing factors for DCT vehicle start process,the research status of clutch control strategies is stated. Considering two performance indicators for DCT vehicle start,i. e. jerk and slipping friction work,based on such factors as start time and power cycle,analysis and comparison of the two start modes are conducted.
