| Abstract: | For a study on the torque fluctuation in the switching process from motor drive to engine drive for a new type of hybrid powertrain system with planetary gear mechanism,a dynamics model for the hybrid powertrain system is built and the process of power switching is analyzed.A torque coordinated control strategy for the process is proposed and verified by simulation and bench test.The results show that the torque coordinated control strategy can effectively reduce the torque fluctuation in power switching pr... |
