Abstract
A control method for a hybrid powerplant includes receiving a pre-transition signal, and selectively adjusting a combustion torque of an engine of the powerplant between a first torque value and a second torque value prior to a deactivation transition period based on the pre-transition signal, wherein the second torque value is less than the first torque value. The method further includes selectively adjusting an electric drive torque of an electric machine of the powerplant prior to the deactivation transition period based on the pre-transition signal and the combustion torque. The selectively adjusting the electric drive torque includes adjusting the electric drive torque such that a sum of the combustion torque and the electric drive torque is equal to a desired drive torque of the powerplant during a pre-transition period prior to the deactivation transition period. A related control system is also provided.
