【摘要】 传统内燃机汽车的使用给人类带来了严重的环境污染和石油资源危机问题，为了解决这些问题，同时具有纯电动汽车和传统内燃机汽车优点的混合动力电动汽车应运而生，并成为有效方法之一。混合动力电动汽车是发动机、电机和蓄电池协调工作的整体，其中，本文使用了集成一体化起动／发电机(Integrated Starter／Generator-ISG)技术，它是当前国际公认的、未来汽车的先进技术之一，非常适合今天及未来提高汽车经济效率及改善排放等方面的要求。 本文是以夏利7100轿车为原型进行的混合动力电动汽车控制策略的仿真研究。首先对混合动力电动汽车的结构形式和混合程度分类进行介绍，确定了本文以并联式、ISG轻度混合动力电动汽车为设计方案。其次针对确定的方案，在简要分析了ISG轻度混合动力电动汽车结构和功能的基础上，对各个部件进行选型及参数确定。再次，对并联式混合动力电动汽车的工作模式进行分析，制定了汽车在起动、巡航、加速或爬坡、怠速及减速制动时的控制策略，在综合分析了各部件特性之后，制定了适用于本系统的基于逻辑门限值的瞬时优化控制策略，并确定了燃油消耗效率的评估方法。最后，使用MATLAB／Simulink仿真工具建立了整个系统的燃油消耗评估模型，并利用建立的模型对该款混合动力车在中国典型城市公交循环工况下的燃油经济性进行仿真分析和比较。 仿真结果表明，采用了合理的控制策略和有效的控制算法的ISG轻度混合动力电动汽车的燃油消耗指标优于传统汽车，验证了ISG混合动力电动汽车动力匹配的合理性及高效性，并验证了控制策略制定的有效性，为ISG轻度混合动力电动汽车的进一步优化设计提供了参考和依据。更多还原

【Abstract】 Conventional automobile has caused serious environment pollution and crisis of petroleum.In order to solve these problems, Hybrid Electric Vehicle (HEV) which combines the advantages of the conventional automobile and electric vehile arises and becomes one of the most feasible ways to solve pollution and fuel problems.HEV is a whole body assort with engine, generator/motor and battery. As one of the world-famous advanced technologies for future car, Integrated Starter/Generator (ISG) we used satisfies the requirements of high efficiency and low exhaust.Based on the Xiali 7100, the paper study on the control strategy of HEV with simulink.First, it introduces the HEV class on the structure format and hybrid degree.As a conclusion, it chooses to design Parallel, Integrated Starter/Generator mild HEV (ISG-MHV).According to the conclusion, based on analysis about the structure and functions of ISG-MHV, the parameters designing method of the powertrain components are presented. After analyzing the working modes of ISG-MHV, the control strategy during start, cruise, accelerate or climb, idle and brake is defined.According to the object considering the minimum fuel consumption and the battery SOC, the paper designs an instantaneous optimization control strategy based on the logical gateway and ensures the fuel consumption evaluated method.At the end, a fuel consumption evaluated module is built with MATLAB/Simulink.According the Chinese type city bus circle, the fuel economy performance is analysed and compared using the module. Compared with the conventional vehicle of similar dynamic performance, the fuel economy performance of the ISG-MHV increased using reasonable control strategy and effective arithmetic.It is proved that the powertrain design and the control strategy are effective.It also provides a base for ISG-MHV further optimized design.更多还原
