Energy management strategies for hybrid electric vehicles

Coupled with the accelerated search of "clean generation" of electric energy is the growing need for alternative energy source in urban transportation that can reduce the overall impact on air pollution. Hybrid electric vehicles, HEV, are offering the best possibility for the use of new energy sources, because electricity can result from a transformation with high efficiency in a system with electric drives and components. In this paper the authors pretend to show the possible application of a particular motion system, the joint system, JS, in a simplified HEV model. A special energy management strategy must be applied in order to take into account the operation modes of the JS and the particular constraints linked to the structure and configuration of an HEV. An application-oriented overview of a rule-based control is presented and is demonstrated the suitability for the control of HEVs.
