Abstract
A method to control an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and first and second electric machines to transmit power to an output member includes determining motor torque constraints and battery power constraints. A preferred output torque to an output member is determined that is achievable within the motor torque constraints and is achievable within a range for a first torque input and is achievable within a range for a second torque input and is based upon the battery power constraints.
