Abstract:
1. A method for controlling a powertrain comprising an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and an electric machine adapted to selectively transmit mechanical power to an output member, wherein a microprocessor performs the following steps: operating said transmission in an operating range state wherein an input speed of an input shaft of said transmission can operate independently of an output speed of said output member and wherein a reactive torque is transmitted through said transmission; monitoring commands affecting a requested output torque; monitoring a calculated output torque; determining said operation of said transmission to comprise one of stable operation and transient operation; if said operation comprises stable operation, controlling said engine and said electric machine based upon said commands affecting said requested output torque; and if said operation comprises transient operation,
