    • PCT No. PCT/EP93/01127 Sec. 371 Date Oct. 24, 1994 Sec. 102(e) Date Oct. 24, 1994 PCT Filed May 7, 1993 PCT Pub. No. WO93/23689 PCT Pub. Date Nov. 25, 1993The invention concerns a control system (10) for changing automatic gears (3) that operates according to fuzzy logic methods. All the fuzzy-production rules are divided into at least three sections: a set of basic rules to determine the gear-changing point in a consumption-oriented driving style, a set of adaptation rules to modify the set of basic rules depending on a current driving style and an identification set of rules for classifying the driver according to his/her driving style. By way of a supplementary set of adaptation rules the set of basic rules can be additionally modified according to a current driving condition. Individual function blocks (11 to 15) operate preferably according to the same inference mechanism. Gamma operators are used in order to approximate as closely as possible human behavior. A process is proposed for generating membership functions to determine a running condition by fuzzy-production rules. In a preferred embodiment the adaptive gear-changing behavior is activated by forming offsets. Priorities are allotted to the rules especially for reasons of safety and reliability.
