Simulation and fuzzy logic analysis on an Off-road HEV

The hybrid electrical vehicle (HEV) has draw researchers' attention recently. This paper mainly discusses the control strategy of HEV based on fuzzy logic. By using this control strategy, the work space and work efficiency of engine are optimized, which play a vital role on improvement of the operation performance of HEV. Meanwhile, the strategy has been applied to optimize the power balance of battery, which includes the characteristics of battery in the controller. Based on the Matlab/Simulink, the simulation results confirmed the excellent effectiveness of our control strategies, which optimized the fuel consumption of engine and the power balance of battery successfull
