Simultaneous optimisation of fuel consumption and emissions for a parallel hybrid electric SUV using fuzzy logic control

International Journal of Vehicle Design (IJVD), Vol. 46, No. 2, 2008

Abstract: A Fuzzy Logic Control Strategy (FLCS) for a parallel hybrid electric SUV is described. In this control strategy, an optimal torque provided by the Internal Combustion Engine (ICE) is first evaluated based on the ICE characteristics. Then, with the consideration of control-state constraints and the characteristics of other power components, the acquired optimal torque is modified by a fuzzy logic controller. Consequently, the actual required output torques of the ICE are figured out. The proposed control strategy was modelled in Simulink and incorporated into the vehicle simulation software Advisor. The simulation results demonstrate that the proposed control strategy is more effective overall than the conventional.
