摘　　要：以混合动力商用车电控机械式自动变速器(Automated Mechanical Transmission,AMT)换挡过程为研究对象,以减小换挡冲击和缩短换挡时间为目的,使用Simulink搭建了包含动力源动态协调与基于最优控制原理的电动机主动同步控制的无同步器换挡控制模型,并使用AMESim建立了动力系统及整车动力学仿真模型;以5挡升至6挡为例,采用AMESim与Simulink开展联合仿真分析,并与传统换挡策略的换挡性能进行了对比。仿真结果表明,换挡过程中,同步时间缩短21.42%,最大冲击度减少24.88%,整个换挡时间缩短18%。最后,基于dSPACE半实物仿真平台对所提控制策略进行了实时验证。This study takes the shift process of a commercial vehicle equipped with an automated mechanical transmission(AMT)as the research object,with the aim of reducing shift shock and shortening shift time.Simulink was used to construct a shift control strategy without the participation of synchronizers,which includes dynamic coordination of power sources and active synchronization control of motors based on optimal control principles.Then,AMESim was used to establish a complete vehicle shift simulation model.Taking the shift from fifth gear to sixth gear as an example,a comparative analysis of the shift performance between AMESim and Simulink joint simulation and traditional shift strategies was conducted.The simulation results show that the synchronization time is reduced by 21.42%during the shift process,the maximum impact is reduced by 24.88%,and the entire shift time is reduced by 18%.Finally,the control strategy proposed in this research was validated in real-time using the dSPACE semi physical simulation platform.
