摘要：随着当今社会不断的高速发展，交通系统的不断完善，人们的出行已经离不开汽车了，传统的燃油汽车在提供给人类方便的同时也伴随着环境的污染问题日趋严重，而混合动力汽车有助于改善环境污染问题，所以优化混合动力汽车的能源管理系统势在必行。优化能源系统管理的前提是实时获取汽车在行驶过程中的各类行车信息，本课题主要通过利用TMS320F2812系列的采集芯片模块以及JTAG接口电路并使用DSP程序设计其主要程序语言组成车辆数据采集系统，并采用CAN总线通讯技术，对车辆实际运行过程中的各种数据进行跟踪记录，并建立车辆数据采集系统并对采集到的数据进行储存分析，为需求功率预测提供数据。最后通过Advisor仿真软件对设计好的数据采集系统进行模拟测试，进行仿真验证车辆各项性能指标的优化，从而提高燃油经济性。77011

Design of data analysis system for hybrid electric vehicle based on data fusion

Abstract：With the rapid development of today's society, the continuous improvement of the transportation system, people's travel has been inseparable from the car, the traditional fuel vehicles in the convenience provided to the human also accompanied by environmental pollution is becoming increasingly serious, optimizing the hybrid car The energy management system is imperative to optimize the energy system management is the premise of real-time access to the car in the process of driving all kinds of traffic information, the subject mainly through the use of TMS320F2812 series of acquisition chip modules and JATG interface circuit and use DSP program design The main program language composed of vehicle data acquisition system, and the use of CAN bus communication technology as a vehicle driving process to collect the data transmission, The data of the various data during the actual operation of the vehicle are tracked and the vehicle data acquisition system is established and the collected data is stored and analyzed to provide data for the demand power forecast。 Finally, the developed data acquisition system is simulated by Advisor simulation software, and the factors influencing the driving power of the vehicle are obtained, so as to improve the fuel economy。
