Research On The Parallel Hybrid And Simulation Of Composite Power Supply Project Based On The Software Of Cruise

The article firstly analyses the strategic needs and the urgency of developing the new energy vehicles from the following aspects:resource crisis, environmental pollution and the national new energy vehicles project. The paper finally choose the parallel hybrid vehicle as the research object after stating the three kinds of structures and characteristics of the hybrid vehicle in detail.Secondly, the article introduces the idea and the control logic of the hybrid vehicles control strategy fully and builds the controller model of the vehicle through the software of Matlab/Simulink. The vehicle controller model is mainly consisted of control module of torque distribution, control module of SOC balance and control module of automatic clutch.Thirdly, the article chooses the simulation result of the forward simulation structure which is more practical than the back simulation structure. It also builds the hybrid system simulation model by using Cruise software. And the paper makes the hybrid system come true by means of vehicle controller model which is built by Simulink and the hybrid system model that by Cruise.Finally, the thesis suggests the plan which mixed the battery with the super capacitor, facing the bottleneck problems of the hybrid battery energy storage system. It not only debates the characteristic of the plan but also completely states the technical characteristics of the DC/DC power supply control ideas and the system control strategy model.The article aims at research on the simulation analysis of hybrid by the Cruise software in order to provide an efficient and fast method, which can contribute for the optimization of vehicle control strategy and the advanced plan. And it will be applied in more wild fields. What’s more, the project which combined the battery and super capacitor supplied a good project and directed the future of the research for the difficulty of single storage energy.
