| 摘 要： | 混合动力汽车(HEV)大都在原有液压制动系统的基础上增加了电机能量回收制动,能量回收制动力矩的存在使得传统液压制动控制策略必须进行调整以确保制动安全性。提出了一种综合制动控制策略,基于总制动力矩的动态分配,采用模糊控制逻辑对液压制动力矩和能量回收制动力矩进行动态调整,两种制动力矩在该控制策略下能够协同工作,仿真结果表明该控制策略稳定有效,在确保制动安全性的同时能够有效回收制动能量。

| Abstract: | Most hybrid electric vehicle (HEV) employs both hydraulic braking system and regenerative braking system together, due to the effect of regenerative braking torque; the traditional hydraulic braking control strategy should be adjusted to assure the braking safety. A combined control strategy was proposed, and a fuzzy logic approach was applied to dynamically adjust the hydraulic braking torque and the regenerative braking torque which based on the dynamic distribution of total braking torque, a good compromise between two kinds braking torque could be obtained for the vehicle. The simulation results shows that the proposed strategy is steady and effective, and it can regenerate energy effectively and assure the braking safety. |
