METHOD AND APPARATUS FOR DETECTING ENGINE FIRING IN A HYBRID POWERTRAIN SYSTEM

A method for controlling a hybrid powertrain system includes commanding engine operation to transition from an engine-off state to an engine-on state. A control scheme detects engine firing based upon input speed, input torque and a change in the input torque.
