Abstract
Systems and methods for operating an engine that may selectively enter and exit a fuel cut-off mode are described. In one example, the method holds the engine in the fuel cut-off mode even though a propulsive effort pedal is applied. An electric machine may provide torque to a vehicle driveline while the engine is in the fuel cut-off mode.
