摘要

  Power system structure of hybrid electric vehicle impact s critically on the performance of the vehicle.A power-integrated transmission mechanism is put forward, which consists of 2 planetary gear system, 1 engine, 1 electric motor and some clutch es.The mechanism can provide some operating modes like motor drive, engine drive, hybrid drive, and so on, these modes can be classified into 13 sub-modes, the modes can be switched freely.A operating switching procedures is gave, a control strategy for switching is designed , which based on neural fuzzy algorithm, and the rationality of the control strategy is verified by simulation.
