四轮驱动电动汽车再生制动控制策略研究 摘要 电动汽车显著的特点是能够进行再生制动，也就是当汽车制动时，可以将汽车在制动过程中的部分动能转变为电能并储存到蓄电池中，从而提高了蓄电池电能的利用率，提高电动汽车的续驶里程。当前制约电动汽车产业化的瓶颈是电动汽车续驶里程短，而再生制动是电机的固有特性，它能充分发挥电动汽车的优点，并且还能够同时实现节能与电气制动两个目的，故对再生制动的研究在电机各类应用场合都得到了广泛的关注。 关键词：iECar；电动汽车；再生制动；控制策略 STUDY ON FOUR-WHEEL DRIVE ELECTRIC VEHICLE REGENERATIVE BRAKING CONTROL STRATEGY ABSTRACT regenerative braking is striking characteristic of electric car，when the car is braking, part of the kinetic energy in the braking process can be turned into electricity and stored into the battery, so as to improve the utilization rate of the battery power, improve the electric car trip range of. Currently the bottleneck of restricting the industrialization of electric vehicle is that the electric car trip range is short, and the regenerative braking is the inherent characteristics of the machine, it can give full play to the advantages of electric cars, and also can realize energy saving and electrical brake two purposes at the same time, so the study of regenerative braking in motor all kinds of applications received widespread attention . This paper that consider the timely all-wheel-drive structure characteristics of the electric car wheel drive network have set up relevant model of regenerative braking system , and the characteristics of iECar regenerative braking process has carried on the analysis and research,on the basis of the domestic and foreign existing related research results, this paper put forward the suitable for this project iECar electric vehicle regenerative braking control strategy, the main research contents as follows: Key words: electric vehicle; regenerative braking; control strategy  目录 1 绪论 1 1.1 课题研究的背景及意义 1 1.2 国外研究现状 2 1.3 国内研究现状 5 1.4 论文主要研究内容 8 2 再生制动系统结构分析 9 2.1再生制动系统概述 9 2.2 整车控制系统 10 2.2.1 驱动系统 10 2.2.2 制动系统控制单元ECU 13 2.2.3 能源管理系统 14 2.3 制动系统 14 2.4 轮毂电机 15 2.4.1 轮毂电机应用特点 15 2.4.2 轮毂电机在上的应用 16 2.5 储能装置 18 2.6 本章小结 19 3 再生制动控制策略的研究 20 3.1 再生制动 20 3.1.1 电动汽车再生制动的定义 20 3.1.2 再生制动的作用 20 3.2 iECar再生制动的基
