    摘要： A system and method of controlling first and second electric motors of a vehicle having an electrically variable transmission during an engine start/stop operation. The system and method determine an input speed profile and an input acceleration profile based on an optimum engine speed, determine a requested output torque based on a plurality of torque limits and a desired output torque, determine first and second feedforward motor torques based on a requested output torque and the input speed and input acceleration profiles, determine first and second feedback motor torques based on a difference between the input speed profile and an actual input speed, and using the feedforward and feedback first and second motor torques to control the operation of the first and second electric motors when an engine is being turned on or off.

    摘要： An electro-mechanical drive unit connectable with multiple power sources for launching and propelling a vehicle includes an output member, a stationary member, a gear-train, and a torque-transmitting device. The drive unit also includes a compound planetary gear arrangement having a first, second, third, and fourth junction points. The power sources include a first motor/generator and a second motor/generator. The second motor/generator is operatively connected to the compound planetary gear arrangement at the first junction point via the gear-train and the output member is operatively connected to the compound planetary gear arrangement at the second junction point. Additionally, the first motor/generator is operatively connected to the compound planetary gear arrangement at the fourth junction point. Furthermore, the torque-transmitting device is engageable to ground the third junction point to the stationary member.
