Abstract
A powertrain includes an electric motor and a first planetary gear stage having a first rotatable member drivingly connected to the electric motor and at least one second rotatable member. A second planetary gear stage includes a third rotatable member drivingly connected to the at least one second rotatable member and includes at least one fourth rotatable member. One of the third rotatable member and the at least one fourth rotatable member is connected to an output member. A passive one-way clutch and a selectable one-way clutch are associated with at least one of the first and second planetary gear stages for varying operation of the first and second planetary gear stages based upon an operation state of the selectable one-way clutch and a direction of rotation of the electric motor.
