Abstract:
1. A powertrain for a vehicle, the powertrain comprising: a first electric motor; a second electric motor; an internal combustion engine; and a transmission including: wherein the transmission is operable in a first electric mode with the first torque transmitting mechanism coupling the second planetary gearset and the stationary component, the third torque transmitting mechanism coupling the first planetary gearset and the stationary component, and the second torque transmitting mechanism de-coupling the first electric motor and the second planetary gearset to engage both the first electric motor and the second electric motor simultaneously to provide vehicle propulsion when the internal combustion engine is off; wherein the transmission is operable in a second electric mode with the second torque transmitting mechanism de-coupling the first electric motor and the second planetary gearset, the first torque transmitting mechanism de-coupling the second planetary gearset and the stationary component, and the third torque transmitting mechanism coupling the first planetary gearset and the stationary component; and wherein the transmission is operable in a third mode with the second torque transmitting mechanism de-coupling the first electric motor and the second planetary gearset, the first torque transmitting mechanism coupling the stationary component and the second planetary gearset, and the third torque transmitting mechanism de-coupling the first planetary gearset and the stationary component to provide vehicle propulsion from the second electric motor.
