车用动力电池混合预热远程控制系统设计
摘要： 当今世界，随着经济、科技的高速发展，人们也日益意识到能源的问题。作为世界经济、科学发展的支柱产业之一的汽车业，也面临着新的挑战与机遇。为了减少燃油的消耗并降低有害气体的排放，目前汽车业的发展方向为混合预热汽车与电动汽车。传统混合预热汽车，能减少一定的燃油消耗，但是并不能彻底实现燃油替代。而电动汽车实现了零油耗，零排放，但是续驶里程较短。因此，结合了两者优点，可通过外部电网充电的车用动力电池混合预热汽车（Plug-in Hybrid Electric Vehicle，以下简称EK2）成为了研究的热点。
本文根据EK2技术的研究现状与发展趋势，以满足整车动力性能和提高整车经济性能为目标，设计适合于城市工况的EK2EK2远程，并设计适用于该EK2的远程控制系统。
本文首先进行EK2EK2远程关键部件设计，包括发动机、电动机、电池的选型与参数匹配，并在AVL CRUISE软件中构建EK2EK2的整车模型。通过分析车辆在各个工作模式下的能量流动，针对EK2EK2的特点，设计基于规则的逻辑门限值的远程控制系统，在MATLAB/SIMULINK中建立EK2EK2远程控制系统的仿真模型。最后通过CRUISE与MATLAB/SIMULINK的联合仿真，检验远程控制系统的效果。仿真结果表明，本文设计的EK2EK2，在满足动力性要求的基础上，能量消耗明显下降，尾气排放明显减少，达到设计目标。

Abstract: The world today, with the rapid development of economy and technology, people are increasingly aware of the problems of energy. As the pillar industries of the world's economic, scientific development, automobile industry is also facing new challenges and opportunities. In order to reduce fuel consumption and reduce harmful exhaust emissions, the direction of development of the automotive industry is hybrid vehicles and electric vehicles.
Traditional hybrid vehicles can reduce fuel consumption, but not the full realization of the alternative fuel. Electric vehicles to achieve a zero fuel consumption and zero emissions, but the short for driving range. Combines the advantages of both, the Plug-in Hybrid Electric Vehicle (hereinafter referred to as the EK2) which can be charged by an external grid has become a research hot spot.
Based on the research status and development trend of the EK2 technology ，to meet the goal of vehicle dynamic performance and improve the vehicle of economic performance, design the EK2 bus power system which is suitable for urban conditions , and design the bus control strategy.
Firstly, design the key components of the EK2 bus power system, including the selection matches the parameter of the engine, electric motor, battery, and build the EK2 bus model in software AVL CRUISE. Design rule-based logic threshold control strategy through the analysis of the energy flow of vehicles in each operating mode, the characteristics of the EK2 bus, established in MATLAB / SIMULINK simulation model of the EK2 bus power system control strategy. Finally, build a CRUISE and MATLAB /SIMULINK simulation, inspect and control the effects of the strategy. The simulation results show that this paper, the design of the EK2 bus, to meet the power requirements on the basis of energy consumption decreased emissions significantly reduced to achieve the design goals.
