摘　　要：制动能量回收技术是电动汽车节能和环保的关键技术之一,技术难点在于如何在保证制动安全的前提下,使液压制动系统和制动能量回收系统协调工作,既符合驾驶员的制动意图又具有较高的制动能量回收率。首先,将模糊控制理论用于驾驶员制动意图辨别,提出制动能量回收控制策略。其次,利用MATLAB/Simulink平台,建立制动能量回收控制系统模型,利用AVL CRUISE建立整车模型。最后,基于不同的制动强度,进行联合仿真分析,综合制动能量回收率在60%以上,验证了该方法的有效性。As a key energy-saving and eco-friendly technology, braking energy recovery has become an important means of improving energy efficiency of electric vehicles. The key point of braking energy recovery of EV is how to make the hydraulic braking part and braking energy recovery part work together well to meet the driver＇s braking intention and regenerate as much energy as possible. This paper focuses on the identification of braking intention for EV based on fuzzy theory. A control strategy of braking energy recovery is proposed. Based on MATLAB/Simulink, a control model of braking energy recovery is built. A vehicle model is built based on AVL CRUISE. The method proposed in this paper is validated by combined simulation and analysis on the different braking conditions.
