Design of an Integrated VDC/EMS System for Hybrid Electric Vehicles

In this article an integrated controller has been designed for hybrid electric vehicles through controlling of vehicle dynamic and energy management system. This integrated controller was designed within three layers. The control strategy has to determine the power distribution between internal combustion engine and electric motor to minimize fuel consumption and allowing the vehicle to be charge sustaining. Using a nonlinear eight degrees of freedom vehicle model, the simulation results illustrate considerable improvements that are achieved in vehicle handling and minimization of the vehicle fuel consumption through the integrated control system.
