A method for controlling a hybrid powertrain includes monitoring input torque of an input member and may include determining an oscillation torque. The method monitors critical vehicle characteristics, including at least a transmission operating mode and an input speed, and operates the powertrain at the input torque. The method compares input torque to a minimum threshold or oscillation torque to a fatigue threshold and identifies a first critical event, which occurs when input torque exceeds the minimum threshold or oscillation torque exceeds the fatigue threshold. The method identifies a first peak with the on-board controller during the first critical event. Peak events occur when the monitored input torque or oscillation torque changes between positive and negative slope. The method identifies a first CVC set occurring with the first peak and may record the first CVC set and the first peak in a look-up table.
