【摘要】 本文针对华晨汽车集团A平台插电式混合动力轿车开发项目,进行相关的研究。根据车型目标,确定了各关键零部件的方案及关键参数,确定了整车控制系统的电气架构及CAN网络通讯,明确了整车控制系统的开发流程。首先,对插电式混合动力车的定义及优势,混合动力车的分类及优缺点进行了综述。根据相关的边界条件(基础车型及性能指标),使用理论计算结合仿真分析的方法确定整车动力系统各关键零部件的解决方案及主参数。在此基础上,对整车进行了总布置设计分析,确定了冷却系统方案。随后,对底盘各系统(转向系统、制动系统、前后桥及弹簧刚度)进行了校核分析,确定了各系统的更改方案。最后,对整车控制系统进行了研究分析,主要包括控制策略控制算法的确定,整车控制系统架构及CAN通讯的方案设计,整车控制开发流程的阐述。本文为A平台插电式混合动力车预研项目的后续工作提供输入。同时整个可行性分析的过程也可以作为华晨汽车工程研究院的经验积累,有助于其他新能源汽车的设计和开发研究。更多还原

【Abstract】 Energy shortage and environment worsening are two big challenges to the word. In the area of automobile, most of the big auto companies are developing new energy vehicle. Plug-in Hybrid Electric Vehicle (PHEV) has the zero emission function like the pure electric vehicle, and the driving distance of PHEV is not be restricted with the capacity of battery like the conventional HEV. So it’s been considered as one important development direction of the new energy vehicle.This paper is based on the A platform plug-in HEV project of Brilliance auto Group, carried out the relative development. Based on the vehicle performance object, the technical solution and main parameters of key components are defined. The electric structure and CAN communication protocol are defined too. The development flow of the vehicle management system is selected.The main content of the paper is as follows,1. Advantage analysis of the plug-in HEV and classification of HEV. The definition and advantage description of plug-in HEV is represented. Plug-in HEV is one important development direction of new energy vehicle. The classification of HEV (serial HEV, parallel HEV, parallel-series HEV) and the character are introduced.2. Definition of the drive-train and key parameters. Based on the relative boundary conditions (vehicle performance target, base vehicle information), the drive-train system is defined. By using theory computation and simulation analysis, the main parameters are determined.3. Proposal design of general layout and cooling system. Because of the restriction of boundary conditions, the proposal design of general layout and cooling system is a difficult task. Depending on the experience and relative information, carrying out repeated check, the system proposal is designed finally.4. Changing proposal of chassis. Based on the result of general layout, the vehicle weight and axle weight distribution are estimated. Using this as the input information, the chassis system (including steering system, brake system and suspension system) is checked and analyzed. The changing proposal is designed.5. Vehicle management system proposal. The several control algorithms are discussed, the using control algorithm is defined. The structure and CAN communication technical proposal are designed. The development flow is defined.This paper can provide input information for the subsequent development work of A platform plug-in HEV project. At the same time the feasibility analysis can accumulate design experience for the Brilliance auto Group, this can help the design and development for the other new energy vehicle project.更多还原
