Abstract
An electro-mechanical drive unit connectable with multiple power sources for launching and propelling a vehicle includes an output member, a stationary member, and a torque-transmitting device. The drive unit also includes a compound planetary gear arrangement having a first, second, third, and fourth junction point. The power sources include a first motor/generator and a second motor/generator. The first motor/generator and the second motor/generator are disposed on a common rotating axis. The second motor/generator is operatively connected to the compound planetary gear arrangement at the first junction point 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.
