Research On Control Strategy Of New Energy Vehicle Based On Driving Behavior Recognition

With the rapid development of automobile industry and people’s living standards greatly improved,car retains in the quantity also gradually increased,and the resulting traditional car caused by environmental pollution and lack of resources has become a serious problem,now the world major research institutions and enterprises to pursue research and new energy vehicles has to imminent.Pure electric vehicles are a new energy vehicles,because it dose not need to rely on fuel to provide power,but it will be converted into kinetic energy,so there is a very good development prospects.But there is a big problem,that is necessary to develop high energy density of the battery and the use of effecient and reasonable control strategy,this paper will study the second issues.According to the above problems,the main research contents of this paper ara as follow:(1) Through the collection and analysis of operation intention and vehicle operation action mode of data,using principal component analysis method to real time recognition of three kinds of operation intention,the driver should be what kind of anctoions.(2) According to the results of operation intention recognition, in order to achieve pure electric vehicles energy optimization control study based on the theory of fuzzy control, for cruise behavior in operation intention, the fuzzy control strategy model is established using Simulink, the control system module embedded in the ADVISOR to complete the simulation experiment.(3) Can use fuzzy control strategy to control the drive motor, the motor can according to the driver and the surrounding environment and reasonable output torque to achieve on-demand supply and use software advisor simulation platform is built.The results also demonstrated that the feasibility of the method. The result shows:(1) The principal component analysis method can be used to determine the impact of the specific operation intention on the driving action.(2) Using the simulation software of MATLAB/SIMULINK to build a simulation model can effectively control of pure electric vehicle mode of operation of the torque coordination. Simulation results show that the this strategy can make the car is stable in the power mode transition to the economic model,can be used as a kind of effective and feasible scheme.(3) Using fuzzy control strategy to control the drive motor, the motor can according to the driver and the surrounding environment and reasonable output torque to achieve on-demand supply and use software advisor simulation platform is built.The results also demonstrated that the feasibility of the method.
