[Abstract]:Hybrid electric vehicle (HEV) is a new type of vehicle which has the advantages of low fuel consumption, low emission, long driving process, moderate price and both advantages of pure electric vehicle and traditional fuel vehicle. With the comprehensive advantages of economy and environment, hybrid electric vehicle (HEV) is recognized as the most feasible green car scheme. The main content of this paper is the control strategy of HEV and the development of real vehicle control system. The control strategy is one of the key technologies of HEV. Energy management and accurate control of power system are the basis of energy consumption and low emission of HEV. The so-called control strategy is to achieve energy management and power systems. The control strategy judges the driving intention according to the driver's behavior, and then meets the needs of family affairs. (1) the development prospect of hybrid electric vehicle is studied. The feasibility of using hybrid power technology on SUV is analyzed. (2) the overall structure layout of hybrid power SUV is analyzed and designed, and the models of vehicle, driver, engine, battery, transmission, clutch and so on are established. Simulation results in matlab/simulink are carried out. (3) according to the design requirements of SUV, the control strategy of hybrid electric vehicle is studied, and a fuzzy controller based on load balancing control strategy is established in matlab. And in the third chapter of the simulation model for simulation verification. (4) the hardware of the controller hardware and hardware matching software as well as the writing of the program are described in detail. The design and development of the control system is written into the real vehicle controller, and road tests are carried out. The feasibility, effectiveness and practicability of the control strategy are verified by comparing the experimental results with the simulation structure.
