a. government a.encies continue to tighten emissions regula.ions due to the continued increa.e in greenhouse ga. production, a.tomotive industries a.e seeking to produce increa.ingly efficient vehicle technology. Hybrid electric vehicles (HEVs) ha.e been introduced to mitiga.e problems while improving fuel economy. HEVs ha.e led to the dema.d of crea.ing more a.va.ced controls softwa.e to consider multiple components for propulsive power in a.vehicle. a.la.ge section in the softwa.e development process is the implementa.ion of a. optima. energy ma.a.ement stra.egy mea.t to improve the overa.l fuel efficiency of the vehicle. Optima. stra.egies ca. be implemented when driving conditions a.e known a.prior. The Equiva.ent consumption Minimiza.ion Stra.egy (EcMS) is a. optima. control stra.egy tha. uses a. equiva.ence fa.tor to equa.e electrica. to mecha.ica. power when performing torque split determina.ion between the interna. combustion engine a.d electric motor for propulsive a.d regenera.ive torque. This equiva.ence fa.tor is determined from offline vehicle simula.ions using a.sensitivity a.a.ysis to provide optima. fuel economy results while ma.nta.ning predetermined high volta.e ba.tery sta.e of cha.ge (SOc) constra.nts. When the control hiera.chy is modified or different driving styles a.e a.plied, the a.a.ysis must be redone to upda.e the equiva.ence fa.tor.
