Since last century, the exhausts of fossil fuel energy, excessive gas emission and global warming have been calling for the alternative methods to generate energy for vehicles urgently. The hybrid electrical vehicle (HEV), which is considered as a potential solution to solve this problem, has draw researchers attention. 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. Though the model based on 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 successfully.
