ABSTRACT:
A method for distributing energy in a vehicle having a hybrid electric drive system that includes an internal combustion engine and at least one electric motor which deliver torque to a primary drive shift having at least two drive wheels operatively associated therewith. The method includes the steps of delivering torque from the internal combustion engine and the electric motor to the primary drive shaft to accelerate the vehicle from a stationary position to a predetermined cruising velocity, disengaging the electric motor from the primary drive shaft once the vehicle has accelerate to the cruising velocity to reduce parasitic drag on the system, and delivering torque from the internal combustion engine to the primary drive shaft utilizing the mean horsepower of the internal combustion engine to maintain the vehicle at the cruising velocity.
