Abstract
A method for controlling a multi-mode transmission system employing torque machines under dynamic operating conditions includes calculating a phase shift between a control parameter of one of the torque machines and a response parameter of the multi-mode transmission system under dynamic operating conditions, comparing the calculated phase shift and an expected phase shift, and executing remedial action when the calculated phase shift exceeds a threshold associated with the expected phase shift.
