A system includes a hybrid power train having an internal combustion engine and an electrical torque provider that combine to provide a total machine torque. The system includes a controller that functionally executes operations to control the hybrid power train. The controller interprets a total machine torque target value and determines a torque contribution for each of the internal combustion engine and the electrical torque provider in response. The controller interprets a supplemental torque contribution value, and controls the internal combustion engine and the electrical torque provider in response to the torque contributions and the supplemental torque contribution value. The supplemental torque contribution value is applied as a limiting value, a target value, or a prescribed ratio for one or both of the torque contributions.
