    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: To eliminate the effect of hysteresis when electrical energy is supplied to an electromagnetic positioning element, for example to an electromagnetic valve, upon change in sign of the electrical energy which is provided from a previously occurring change, additional electrical energy is supplied if the change in energy is counter the direction of the magnetization curve. The extent of the additional energy may be at least as great as the gap between the ascending and descending branches of the hysteresis curves (H1, H2), or may be a quantity obtained by experience or measurement if the gap between the hysteresis curves is known or determinable. If the electromagnetic energy applied is in excess of that for reversal of magnetization, it may be applied for a period of time which is just long enough to permit remagnetization of a magnetic portion of the electromagnetic apparatus (11) but not long enough to cause change in a mechanical output thereof.

    摘要: To effect soft gear change, without shifting jolts or shocks, the output torque of an automotive vehicular internal combustion engine is controlled in dependence on sensing of an overrunning condition signal derived, for example, by the conjunction of the accelerator pedal being in "idle" or "unoperated" condition, and the engine operating at a speed in excess of idling speed. Use of such an "overrunning condition" signal permits ready control of the engine without requiring additional control elements or systems coupled to the gear change apparatus or to the transmission.

    摘要: Reference values are stored for various conditions of gear shift operations of a vehicle motor of a particular type and model for various motor speed and load combinations, the reference values having a magnitude characterizing the gear shifting operation, for example the time interval required from the appearance of a gear shift command until the end of slip in a coupling indicates that the gear shift is complete. As the vehicle is driven, actual values of this magnitude are stored and averaged for a predetermined number of shift operations under the same class of condition. Correction values for the pressure of hydraulic fluid of the gear shift control, originally set at zero for all conditions, are determined by comparison of reference values with average actual values and stored. In subsequent driving, the stored correction values are used to control the pressure of the hydraulic medium to maintain a standard of comfort for all shift operations and new average actual values are used from time to time to modify the correction values for compensation of aging effects.

    摘要: The time required for shifting gears from an old to a new gear and the jolt created by the shift is decreased by initiating a known overlap of disengagement of the friction elements of the old gear and engagement of the friction elements of the new gear at the time the hydraulic unit operating the friction elements of the new gear is completely filled. Since a voltage pulse occurs across the solenoid winding of the pressure regulator when the hydraulic unit is completely filled, the solenoid valve is monitored by a threshold circuit which responds to the pulse. The output of the threshold circuit sets a flipflop. The flipflop is reset in response to a gear shift initiation signal furnished by a microprocessor. The microprocessor samples the flipflop output to determine whether the hydraulic unit is completely filled and initiates the overlap portion of the gear shift when this is so.

    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.
