In the brake systems a proportioning valve which reduces the brake pressure at each wheel cylinder for anti-locking of rear w~1eels 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 a electronic brake pressure distribution system using a fuzzy controller in order to exactly control brake pressure using a close 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 good performance of brake system more than that of the previous system.
