    摘要: A device for controlling the gear ratio of a continuously variable transmission. The theoretical rotational speed or transmission ratio is fed to the signal input of a set-value filter (44). The time constant (T.sub.-- RS) of the set-value filter (44) is adaptively controlled so that the change in transmission ratio takes place in accordance with a transition function whose limit is defined by a maximum variation speed. The principal advantage of the invention is that the vehicle is not slowed when shifting down to lower transmission ratios.

    摘要: The 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.

    摘要: The invention concerns a gear-change control systems (10) for an automatic transmission (3). Input variables, derived from a driver-vehicle system, are established. Output variables are established by fuzzy logic methods and used to determine a gear-change ratio. A fuzzy logic module, which imitates the operating method of a logical flip-flop and additionally permits continuous intermediate values, is used to consider driving states brought about by different situations.

    摘要: The 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.
