Due to the complexity of PHEV powertrain, as an important research method, computer simulation technology has been playing more and more significant role in the study of PHEV control strategy. In this paper, both the methods of experiment modeling and theoretical modeling are adopted. By making use of computer simulation, analyzing control strategy and its corresponding result, choosing control parameters, a forward-facing control system simulation software and models of PHEV powertrain based on MATLAB/Simulink are developed to make a study of the PHEV control strategy. Simulation results are also achieved and shown in the paper.
