A general formulation of the instantaneous power split strategy between an IC engine and an electric machine in a charge-sustaining hybrid-electric vehicle is given. It is based on the instantaneous optimization of an equivalent fuel cost based on the average 'cost' of electricity through the various power paths (present and future). This control strategy was implemented on a HEV prototype and real-world results are presented here, demostrating that this approach provides excellent fuel efficiency along with robustness and charge sustaining operation. Then, a general and scalable formulation of this control strategy is proposed.
