Matlab-simulink software was utilized to build the model of PHEV with power split transmis-sion.The instantaneous performances of engine,TM-motor,ISG-motor and battery in all kinds of working conditions were analyzed.Based on the model,a power distribution strategy was proposed for the least of general energy consumption.The computed result shows that the strategy makes the best fit of engine,TM-motor and ISG-motor,reduces the general energy consumption rate.
