摘　　要：为了提高某型混合动力AMT汽车的换挡品质,根据其结构与工作模式的特点,对其两种典型工作模式进行研究,并提出了相应的换挡控制策略。在发动机驱动模式下,采用电动机和发动机电子节气门联合调速的换挡控制策略;而在发动机和电动机混合驱动模式下,采用不分离离合器的电动机主动调速的换挡控制策略。通过仿真和台架试验对该控制策略进行了验证。结果表明所采用的换挡控制策略能有效减小换挡冲击,缩短动力中断时间,提高换挡品质。To improve the shift quality of a specific hybrid electric vehicle with AMT, its two typical working modes are studied with corresponding shift control strategies proposed based on the features of its structure and working modes. A motor/engine's electronic throttle combined speed control strategy is adopted for engine drive mode, while a shift control strategy of motor speed active regulation without clutch disengagement is used for engine/motor hybrid drive mode. The control strategies are verified by both the simulations and bench tests. The results show that the control strategies adopted can effectively reduce shift shock, shorten power interruption time and improve shift quality.
