ANTILOCK SYSTEM FOR ELECTROMECHANICAL VEHICLE BRAKE SYSTEM BASED ON FUZZY CONTROLLER

摘要

PROBLEM TO BE SOLVED: To perform an optimal ABS control, by supplying a nominal brake pressure to a vehicle brake system generated by a unit having an integration characteristic on the basis of a change rate of a brake pressure outputted from a fuzzy controller, and simultaneously, by supplying a current brake pressure from the vehicle brake system as a comparison value. ;SOLUTION: A fuzzy controller 5 generates a pressure change rate DP by using a fuzzy control base so as to output it to a unit 6 having an integration characteristic. The unit 6 generates a signal corresponding to a nominal pressure PN so as to output it to an input side of a unit 7 comprising an electric brake actuator and an actuator controller. Lastly, an electric brake 8 receives an output from the unit 7. A signal of a current pressure PA in the unit 7 is output to input sides of both a unit 3 and a divider 4. Accordingly, by changing only a follow-up part in the control base with an operation part maintained as it is, excellent and simple consistency is obtained.;COPYRIGHT: (C)2000,JPO
