A system for controlling an internal combustion engine start threshold in a parallel hybrid-electric vehicle. A predetermined conditions tracking module determines whether or not conditions of a plurality of predetermined conditions exist. Responsive to a determination that the conditions exist, a required power estimation module estimates a next acceleration required by the vehicle and a final power requirement for the next acceleration. A propulsion system control module determines if the estimated final power requirement is between a first amount of electric motor power available at a predetermined base engine start threshold and a second amount of electric motor power available at a predetermined elevated engine start threshold. If the estimated final power requirement is between the first and second amounts of power, operation of the vehicle is controlled so as to ensure that the engine start threshold is at the predetermined elevated threshold.
