Research On Dynamics Of Hybrid Electric Vehicles Based On CRUISE And Hybrid Electric Vehicles

With the rapid development of the global economy,global problems such as energy shortage,environmental pollution and climate warming have received increasing attention.The development of new energy vehicles with low fuel consumption and low emissions has become an important development target for the automotive industry worldwide..Hybrid vehicles use a variety of energy sources,while having the advantages of fuel vehicles and new electric vehicles,is an important development direction of modern vehicles.With the application of hybrid vehicles,its power and economy have also become the focus of the society.To this end,this paper takes the hybrid vehicle as the research object,and studies its power and economy.Firstly,on the basis of the previous research results,the function and energy-saving principle of hybrid electric vehicles are summarized,and the system classification is expounded as the theoretical basis of the research.Then,based on a certain vehicle of Beiqi New Energy,the whole model is given.The performance requirements of the car,the selection and setting of the parameters of the hybrid vehicle power system;on this basis,the AVL CRUISE software is used to build the vehicle model,including the whole vehicle,generator,battery,motor,transmission,reducer,etc.The related model is constructed,and the energy management strategy of the hybrid vehicle is given.Finally,combined with the vehicle model of the hybrid vehicle,the simulation platform is built to simulate and analyze the economy and dynamics of the hybrid vehicle,and according to the simulation results,The particle swarm optimization algorithm is used to optimize the parameters of the hybrid vehicle to achieve the goal of improving the overall performance of the hybrid vehicle.Through research,the optimized hybrid vehicle basically meets the basic requirements of power,economy and energy consumption,which can reduce the development cost of the whole vehicle and shorten the development cycle.For the production,modification and application of hybrid vehicles,The important significance and value also have important engineering applications and reference value for improving the production efficiency of enterprises.
