A development of electronic load sensing proportioning valve for control of brake pressure using direct adaptive fuzzy algoirthm 2000-05-0266
In the brake system a proportioning valve which reduces the brake pressure at each wheel cylinder for anti-locking of rear wheels is closely related with the safety of vehicles. But, it is impossible for a present proportioning valve to exactly control brake pressure because mechanically it is an open-loop control system. So, in this paper, we describe an electronic brake pressure distribution system using a direct adaptive fuzzy controller in order to exactly control brake pressure using a closed-loop control system. The object of electronic brake pressure distribution system is to change a cut-in pressure and a valve slop of proportioning valve in order to have better performance of brake system more than that of the previous systems.
