【摘要】：混合动力汽车是在电动汽车发展过程中出现的一种低油耗、低排放、续驶历程长、价格适中,兼具纯电动汽车和传统燃油汽车优点的新型汽车,由于在技术、经济和环境等方面的综合优势,混合动力汽车作为当下最切实可行的绿色汽车方案被认可。本文主要研究的内容是,混合动力汽车的控制策略,与实车控制系统开发。控制策略是混合东里汽车的关键技术之一,整车能量管理和对动力系统的精确控制,是混合动力汽车能耗、低排放基础。所谓的控制策略,是实现能源管理和动力系统。控制策略根据驾驶员的行为判断驾驶意图,再满足家事需求。(1)对混合动力汽车发展前景进行研究,并对SUV上运用混合动力技术的可行性进行了分析。(2)分析并设计了混合动力SUV的整体结构布置,建立了整车、驾驶员、发动机、电机、电池、变速器、离合器等模型,并在matlab/simulink中进行了仿真验证。(3)针对SUV的设计要求,研究了混合动力汽车的控制策略,在matlab中建立了基于负荷平衡控制策略的模糊控制器,并在第三章的仿真模型中进行了仿真验证。(4)对本实车的控制器硬件、与硬件配套的软件以及程序的刷写进行详细说明。并将所设计开发的控制系统刷写到实车的整车控制器中,进行道路试验,通过实验结果和仿真结构的对比分析,来验证控制策略的可行性、有效性以及实用性。
[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.
