    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 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.

    摘要: A process for controlling a clutch incorporated between the driving engine (M) and the gearbox (G) of a motor vehicle, in which the clutch is a bridging clutch (WK) of a hydrodynamic unit or a separating clutch (K) in a driving train. The process uses devices to measure the engine speed (n-M) and the gearbox output speed (n-ab) and a slip regulating switch mechanism (1). The slip regulating switch mechanism (1) determines the pressure for an actuator (3) of the clutch. The control deviations are derived from a comparison (4) of predetermined slip reference values (w) and the actual slip values (s) obtained from the equipment speeds, and converted to pressures in accordance with a predetermined control algorithm in the regulator (6). The clutch output speed (n-K, n-WK) required for a determination of the slip is obtained from the gear ratio (G-x) and the gear output speed (n-ab). During the shift process (t-0 to t-3), a virtual clutch output speed (n-Kvir) is determined and used to further implement slip control, or the pressure for the actuator (3) of the clutch (K, WK) is varied as a function of predetermined parameters.
