摘　　要：基于模块化思想,针对混合动力系统开发的特点,在AVL PUMA Open动态测试系统的基础上搭建了混合动力系统试验台架。针对混合动力系统中关键技术之一的状态切换问题进行研究,提出相应的控制策略,并在混合动力系统试验台架上对状态切换的策略进行验证。试验表明,采用发动机转矩在线估计的动态控制方法能够有效地解决状态切换过程中出现的转矩突变问题,转矩波动的相对幅度可以控制在5%左右。A modularized hybrid powertrain system test bed was set up based on the AVL PUMA Open dynamic test system. The mode switching control is one of the key problems in designing HEV powertrain system. An appropriate mode switching control strategy was worked out and verified on the developed test bed. The test results show that the dynamic control method by means of engine torque on-line estimation can effectively solve the problem of torque changing abruptly in mode switching process, and the torque fluctuation can be restrained within about 5% of the required value.
