The Research And Simulation Of Control Strategy In ISG Iveco Hybrid Electric Vehicle

With emission regulations increasingly stringent and the energy pressure gradually increase,for the current,energy saving and environmental protection is the theme of the development of automobile industry.As a source of clean energy vehicles,electric vehicles has become a hot topic of the automotive industry at home and abroad,but due to the impact of the development of battery technology,its very difficult to be taken to the market in a short period.Hybrid Electric Vehicle integrates the advantages of the traditional cars and electric vehicles,which can be very good to meet the requirements of environmental protection.Before electric vehicle be taken to the market,the hybrid vehicles will become the most potential of the traditional automotive replacement for him.Control strategy is the key to achieve good vehicle performance of Hybrid vehicles,the formulation of to carry out the research of control strategies has become the top priority of hybrid vehicles.In this paper, control strategy is the key to achieve good vehicle performance of Hybrid vehicles,carrying out research of control strategies has become the top priority of hybrid vehicles.In this paper,take light commercial vehicle IVECO as the study object,the hybrid electric vehicle control strategy have been researched through the software simulation,laying the foundation for vehicle development.Taking ISG motor coupled with the engine as the powertrain rigid structure in the thesis,key components and parameters of its powertrain have been selected;a detailed analysis of electric assist control strategy and torque split control strategy is carried out,pointing out their weaknesses and carrying out appropriate improvement.In accordance with the characteristics of the study object,SOC-based torque distribution fuzzy control strategy is established;Finally,taking simulation software ADVISOR as a platform,simulation models of power system are set up.Through simulation,the control strategy is proved to be effective and feasible,the economy and power performance of ISG IVECO Hybrid Electric Vehicle are forecasted,all of which can laid a foundation for next research and exploiture works on the ISG IVECO Hybrid Electric Vehicle.
