MATLAB混合动力汽车车载故障诊断系统设计

摘要：近年来，随着社会的不断发展，人们对生态的保护越来越关注，作为大气污染主要排放源的汽车也进行了相应的改变，逐渐由燃油车向电动汽车过渡。混合动力汽车是集内燃机与电动机为一体的过渡型动力汽车，是当前主要的替代内燃机汽车的车型。在如今能源日益紧张、空气日渐污浊的情况下，人们越来越注重自己生活的环境质量好坏，而混合动力汽车一种节能，低碳排放的交通工具，因此在不久将来其一定会成为消费者热衷的车型，然而由于混合动力汽车的复杂程度较传统汽车相比有较大的难度，因此其检测文修也对文修人员提出较高要求，本文对混合动力汽车的检测与文修进行了简单的概述。对混合动力系统的各部件进行建模，其实包括发动机模型，电池管理系统模型，并利用基于MATLAB/SIMULINK界面的ADVISOR软件进行仿真，进行汽车车载故障的设计。33888

Hybrid electrical vehicle fault diagnosis system design
Abstract: In recent years, with the continuous development of society, more and more attention to the ecological protection are paid by people. As the main sources of atmospheric pollution, cars also have a corresponding change and gradual transition from fuel vehicles to electric cars. Hybrid vehicle is a set of internal combustion engine and electric motor as one of the transitional powered cars and is currently the main alternative to internal combustion engine cars as well. In today's increasingly tense energy situation, the air is dirty. People pay more and more attention to the environmental quality of their lives, and hybrid vehicle energy saving, low carbon emission vehicles, so in the near future it will become a consumer to be fond of cars, but because of the more complexity of hybrid cars than the traditional car compared with great difficulty, so the detection of repair need personnel to put forward higher requirements, inspection and repair of HEV in this paper gives a brief overview. Modeling of the various components of the hybrid system, it includes engine model, battery management system model, and use ADVISOR software based on MATLAB/SIMULINK simulation interface in order to check and design vehicle fault.
