Abstract： In order to solve the problems of the model developed with Simulink can only be run under Matlab environment and the interface of the model is not amiable enough to operate，the Simulink and VC++ hybrid programming method was investigated in developing software used for electrical multiple unit（EMU） traction drive system. After the analysis of the advantages and disadvantages of the Simulink and VC++ at programming and developing simulation model，the relationship between the simulation window and simulation kernel was established. A method that simulation window and simulation kernel exchange data through data interface was presented to the hybrid programming method. The traction drive simulation software was run on one computer without Matlab installed. The result is fully consistent with the result of Simulink. The result shows that not only the software can be run independent of Matlab environment，but also it is valid and useful.
