Abstract
Method for optimizing the operational efficiency of a hybrid electric vehicle is disclosed. The method comprises operating an engine of a hybrid electric vehicle preferentially on an optimized power curve of the engine for maximizing the efficiency of the engine and sensing a state-of-charge (SOC) condition of a battery of the hybrid electric vehicle being at a preferential value indicative of no additional charging being desired. The running torque of the engine is reduced below the optimized torque curve to a point that the power produced by the engine is substantially equal to the power demanded for driving the hybrid electric vehicle.
