Abstract
A hybrid vehicle and method for reducing fuel consumption include upper and lower engine speed limits set based upon whether the state of charge of a battery electrically connected to an electric machine, which may be implemented by an integrated starter-generator is sufficiently high to permit the electric machine to provide a temporary torque boost to an engine of the motor vehicle. If the state of charge of the battery is sufficiently high to permit temporary torque boosting, then the upper and lower engine speed limits are reduced from baseline upper and lower limits to adjusted upper and lower limits to reduce fuel consumption of the engine without adversely affecting NVH.
