Zusammenfassung:	PCT No. PCT/EP94/02448 Sec. 371 Date Feb. 28, 1996 Sec. 102(e) Date Feb. 28, 1996 PCT Filed Jul. 25, 1994 PCT Pub. No. WO95/04234 PCT Pub. Date Feb. 9, 1995The invention concerns a control system for shifting gears in an automatic shift transmission (3) by using fuzzy logic methods. Vehicle parameters form input variables (8) that are continuously detected by appropriate means (9). These input variables are further processed in downstream functional blocks (11, 12, 13, 14, 15, 16 and 17). Gearshifting points that ensure an economical driving are determined in the functional block (11) according to fuzzy logic methods. Besides a set of basic fuzzy logic generating rules, additional rules are used to improve driving. For that purpose, the input quantity "desired performance" is taken into consideration in both sets of rules. The desired performance may be a desired acceleration or a desired deceleration. A closed regulation circuit is formed by converting the fictitious quantity desired performance and the quantity driving manner to a physical quantity.
