介绍了一种电涡流电液混合制动系统，以解决传统车辆制动系统存在的磨损、热故障、响应速度慢等问题。建立数学模型，计算涡流制动系统和液压制动系统的扭矩，分析制动力在两种制动系统之间的分配情况。设计了基于LabVIEW和MatLab的PC机模糊控制器，并搭建了一套硬件在环系统，对混合制动系统的性能进行了验证和分析。通过在干、湿沥青路面上的大量试验，该混合动力制动系统在试验台上取得了良好的性能，减少了制动盘的磨损和温度，响应速度明显提高，模糊控制器通过优化滑移率调节保持了较高的利用率，总制动时间比传统液压制动系统的减少幅度较小。
This paper introduces an eddy current and electro-hydraulic hybrid brake system to solve problems such as wear, thermal failure, and slow response of traditional vehicle brake system. Mathematical model was built to calculate the torque of the eddy current brake system and hydraulic brake system and analyze the braking force distribution between two types of brake systems. A fuzzy controller on personal computer based on LabVIEW and Matlab was designed and a set of hardware in the loop system was constructed to validate and analyze the performance of the hybrid brake system. Through lots of experiments on dry and wet asphalt roads, the hybrid brake system achieves perfect performance on the experimental bench, the hybrid system reduces abrasion and temperature of the brake disk, response speed is enhanced obviously, fuzzy controller keeps high utilization coefficient due to the optimal slip ratio regulation, and the total brake time has a smaller decrease than traditional hydraulic brake system.
