- Abstract
This paper introduces an eddy current and electro-hydraulic hybrid brake system to solve problems such as wear, thermal failure, and slowresponse of traditional vehicle brake system. Mathematicalmodelwasbuilt tocalculate the torqueof the eddycurrent brake system and hydraulic brake systemand analyze the braking force distribution between two types of brake systems. Afuzzy 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 systemachieves perfect performance on the experimental bench, the hybrid systemreduces 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.
