Modeling and Simulation Design of Automotive Power System
Abstract With the shortage of energy and environmental pollution, people began to realize the importance of the concept of environmental protection. However, the traditional fuel vehicles are increasingly to make the environment worse, is not conducive to the concept of green life, so the study of a environmentally friendly and economic car is imperative.
This design is mainly based on the MATLAB/Simulink environment, the vehicle dynamic system modeling, and simulation analysis. Specific content as follows:At first,it introduces the simulation environment and the vehicle dynamic systems, including the simulation environment of MATLAB, the definition of automobile power system, classification, arrangement of engine and vehicle power system basic structure. Then it analyzes the operation of automobile power system in theory, mainly including the working principle and the power transmission sequence of the automobile power system. Finally, the mathematical model and simulation results are given, and the simulation results are given.
At present, the world international automobile structure is undergoing major changes, and the automobile power system as one of the key technologies of the automobile development, to promote the progress of the automobile industry has a very significant meaning.
This paper has 29 figures, 3 tables, 26 references.
