Abstract
Methods and systems are provided for raising the speed of a hybrid electric vehicle operating in an electric-only mode. During conditions when the vehicle is driven only by an electric motor, vehicle speed may be raised by spinning the engine unfueled using power from a system battery, while adjusting valve operation to reduce engine pumping losses. In this way, vehicle speed may be raised more efficiently and without damaging rotating transmission components.
