1. , a kind of method that is used to control powertrain system, described powertrain system comprises the driving engine on the input block that is coupled to hybrid gearbox, described hybrid gearbox is operable in transmitting torque between described input block and torque generation device and the output block, and described method comprises:

  • Policer operation person'"'"'s torque-demand;

    Determine the output torque instruction and the output speed of described output block;

    Select candidate'"'"'s input speed of described input block iteratively;

    Be identified for the mechanical horsepower loss in described hybrid gearbox of each described candidate'"'"'s input speed and described output speed;

    AndSelect preferred input speed, described preferred input speed is included in described candidate'"'"'s input speed that described output speed is issued to the minimum mechanical loss in efficiency in the described hybrid gearbox.
