3. Simulation of Hybrid Power-Split System

Due to the complexity of hybrid system, many issues should be considered in the research and development of the hybrid vehicle, such as the choice of components, the determination of the best configuration, the formulation and optimization of vehicle control strategy, etc. Through the simulation technology, reasonable and effective computer models for hybrid vehicle can be established before the technical scheme is determined. Then according to the simulation result, design parameters for each candidate subsystem and hybrid vehicle configuration can be provided. Thus the trail production work of original candidate subsystem and different vehicle configuration can be simplified. After confirming the configuration of hybrid vehicle and each subsystem, the energy distribution strategy can be established quickly and optimized by simulation software.
