Abstract
A hybrid powertrain includes an engine and electric motors configured to transfer torque through a transmission. A method for controlling the hybrid powertrain includes determining a transition window associated with torque output of one of the electric motors coupled to an element of the transmission. A noise reduction control scheme is executed when the torque output of the one of the electric motors coupled to the element of the transmission is within the transition window.
