Energy management system for hybrid electric vehicles

摘要

An energy control unit for a hybrid vehicle is operable to control stored energy of an energy storage unit such that the energy level of the hybrid vehicle is maintained substantially at a desired magnitude. The energy level of the hybrid vehicle is a function of at least: (i) mechanical kinetic energy of the hybrid vehicle; (ii) mechanical potential energy of the hybrid vehicle; and (iii) potential energy of the energy storage unit.
