摘要
在分析和比较混合动力电动汽车(HEV)不同制动控制策略的基础上,提出了一种新的制动控制策略。在MATLAB/Simulink环境下搭建了制动系统控制模型。考虑到能量回收制动力矩和总制动力矩的连续变化,采用模糊控制策略对液压制动力矩进行动态调整。能量回收制动力矩和液压制动力矩在该控制策略下能够协同工作。仿真结果证明该控制策略有效,鲁棒性好。
Based on the analysis and comparison of the various brake control strategy of hybrid electric vehicle（HEV）, a new brake control strategy was proposed. A control model of the brake system was built and tested under the environment of MATLAB/Simulink. Considering the constant change of the total and the regenerated braking torques a fuzzy logic approach was used to adjust dynamically the hydraulic braking torque, so that the regenerated and the hydraulic braking torques can work in coordination. The simulation results show that the proposed strategy is robust and effective.
