摘要：插电式混合动力汽车由超级电容、蓄电池和电动机作为驱动能量来源。制动控制器设计很大程度上决定了整车的动力性和燃油经济型。本文首先了解了混合动力汽车的定义与分类，并详细介绍了插电式混合动力汽车的结构。而再生制动系统是插电式混合动力汽车的关键技术之一，通过在汽车制动或减速时，将汽车的动能进行回收再利用。为了更好地满足混合动力汽车制动力需求,本文提出了基于模糊逻辑的制动力动态分配控制策略。该策略将总制动力动态分配为再生制动力和前后轮摩擦制动力,在保证制动性能的前提下,使电机最大限度的回收制动能量。然后在Matlab/Simulink仿真环境下，在车速相同的情况下，对不同的制动强度进行仿真，得出制动强度越大，能量回收效果越明显的结论。另外在循环工况下的仿真，也得出所提出的模糊逻辑策略，能有效的提高能量回收效率。20356

Plug-in Hybrid Electric Vehicle Brake System Design Based On Fuzzy Logic
Abstract：Plug-in hybrid electric vehicle drive energy source by the super capacitor, the battery and the motor as. Brake controller design largely determines vehicle power performance and fuel economy.This paper first understand the definition and classification of the hybrid electric vehicle, and introduces in detail the structure of plug-in hybrid electric vehicle. The regenerative braking system is one of the key technology of plug-in hybrid electric vehicle, the vehicle braking and decelerating, the kinetic energy of the automobile recycling. In order to better meet the demand of hybrid electric vehicle braking force, this paper presents a dynamic control strategy of braking force distribution based on fuzzy logic. The total braking force dynamic allocation for the regenerative braking force and front and rear wheel friction braking force, the braking performance, the maximum brake energy recovery machine. Then, in the Matlab/Simulink simulation environment, at the same speed, carries on the simulation of different braking intensity, the greater the braking intensity, energy recovery effect is more obvious conclusion. Also in the cycle simulation, the fuzzy logic strategy is proposed, which can effectively improve the energy recovery efficiency.
