Abstract

A method is provided for reducing engine idling time in a hybrid vehicle that includes a vehicle accessory and a hybrid powertrain having an engine , a generator operatively coupled to the engine, and an energy source . The method includes selectively powering the vehicle accessory using the energy source while the engine is not running, monitoring the energy source state of charge, selectively starting the engine when the energy source state of charge is less than or equal to a predetermined minimum state of charge, operating the engine driven generator to recharge the energy source to a predetermined maximum state of charge, and turning off the engine when the energy source state of charge is greater than or equal to the predetermined maximum state of charge.
A hybrid electric vehicle power delivery system is also provided.
