摘要：
A hybrid transmission is operative to transfer torque between an input member and torque machines and an output member in one of a plurality of fixed gear and continuously variable operating range states through selective application of torque transfer clutches. The torque machines are operative to transfer power from an energy storage device. A method for controlling the hybrid transmission includes operating the hybrid transmission in one of the operating range states, determining a first set of internal system constraints on output torque transferred to the output member, determining a second set of internal system constraints on the output torque transferred to the output member, and determining an allowable output torque range that is achievable within the first set of internal system constraints and the second set of internal system constraints on the output torque transferred to the output member.
