【摘要】：随着世界汽车保有量的持续增加和全球石油供应在不久的未来将出现缺口之间的矛盾,同时随着世界汽车技术不断朝着低碳化、信息化、智能化方向前进,新能源汽车已经成为各个大学、研发机构的新兴热点研究领域之一。混合电动汽车(Hybrid Electric Vehicle.HEV)由于其绿色低碳的显著优势,且目前仍处于初始发展阶段,成为全球各大车企着力发展的方向之一,也成为我国政府大力扶持,以实现民族汽车业弯道超车的战略内容之一。本文基于工程项目实践,以插电式并联混合动力物流车驱动控制系统作为研究对象,对永磁同步驱动电机进行了控制方法研究,在此基础上,研究并制定了整车驱动系统的控制策略,最后在仿真平台验证并分析了控制效果。全文主要完成以下几方面的工作:1,介绍了本文研究的背景、意义及路面耦合式(Through The Road.TTR)混合动力汽车的研究现状,分析了混合动力汽车的分类、节能机理及关键技术。2,研究了永磁同步驱动电机的直接转矩控制方法,基于矢量电压开关表搭建了控制模型对永磁同步电机控制策略进行验证分析,并基于空间矢量调制(SVM.Space Vector Modulation)技术进行了优化控制及仿真。3,研究并制定了车辆驱动系统控制策略,主要包括模式划分、动力分配及基于模糊增益调度的协调控制策略,并对策略搭建的内在逻辑进行了详细说明。4,利用MATLAB/Simulink/Simscape模块搭建了路面耦合式混合动力物流车的车辆动态模型,包括驾驶员、发动机、电动机、变速器、离合器、车身、车轮等部件模型。5,介绍实际开发过程中具有的硬件设备,设置目标工况,通过仿真模型进行了驱动控制策略的效果验证和分析。
[Abstract]:With the continuous increase in the world's automobile holdings and the gap in the global oil supply in the near future, as the world's automotive technology continues to move towards low-carbon, information-based and intelligent direction, New energy vehicles have become one of the hot research fields in universities and R & D institutions. Hybrid Electric vehicle. HEV) is still in its initial stage of development because of its advantages of green and low carbon. It has become one of the development directions of the major automobile enterprises in the world, and it has also become one of the strategic contents of the national auto industry to achieve the national auto industry detour overtaking. This paper is based on the engineering project practice, and also becomes one of the strategic contents of our government's support. The control method of permanent magnet synchronous motor (PMSM) is studied in this paper. Based on this, the control strategy of PMSM is studied and worked out. Finally, the control effect is verified and analyzed on the simulation platform. This paper mainly completes the following work: 1, introduces the background, significance and research status of the road coupling rough The Road.TTR. The classification, energy saving mechanism and key technology of hybrid electric vehicle (HEV) are analyzed, and the direct torque control method of PMSM is studied. The control strategy of permanent magnet synchronous motor (PMSM) is verified and analyzed based on the control model of VVS, and the optimal control and simulation based on SVM.Space Vector Modulation (SVM) technology are carried out, and the control strategy of vehicle driving system is studied and formulated. It mainly includes mode partition, power allocation and coordinated control strategy based on fuzzy gain scheduling. The inner logic of the strategy is explained in detail. The vehicle dynamic model of road coupling hybrid logistics vehicle is built by using MATLAB/Simulink/Simscape module. Including driver, engine, motor, transmission, clutch, body, wheel and other components model. The effect of driving control strategy is verified and analyzed by simulation model.
