摘要:
A method for controlling and/or regulating an automatic transmission of a vehicle, depending on the driving route slope in which a winding mountain pass road detection is carried out, depending upon a topography of the driving route, in such a way that a time for either setting or resetting winding mountain pass road detection is determined.
摘要:
A method for controlling and/or regulating a multi-step automatic transmission of a vehicle in which an upshift is prevented if a power limit, of the motor of the vehicle, is reached such that, when a driving situation in which the power limit of the motor is reached and recognized, the motor speed (n) is set at a predetermined limit value (nLimit). In addition, a system for implementing the method according to the invention is also proposed.
摘要:
A method of controlling an automatic transmission of a vehicle in which a hold gear function is activated by a driver request and is deactivated independently of a return condition. To allow an effective, safe to operate, and comfortable use, the return condition depends on one of the following criteria or a useful combination of the same: a flexible time span, consideration of the vehicle stand still time; a rotational speed of the vehicle engine, or one or several parameters which correlate with the engine rotational speed, a new, the same, or a different drive request by the driver, a change in the operating condition of the vehicle, and a plausibility check occurring during the startup procedure.
摘要:
A method is proposed for determining a clutch application point in a transmission of a vehicle having a spring-actuated clutch system in which the clutch application point is adapted according to at least one adequate regulated quantity of the clutch system.
摘要:
A device for evaluating vehicle, driving and operating parameters of a vehicle, in order to adjust the gear ratio of a transmission according to predetermined algorithms, parameters, or characteristic diagrams, selects anew the gear to be adjusted and adjusts the same by way of an evaluation in dependence upon criteria that are specific to the transmission.
摘要:
A method for the operation of an automatic transmission in a motor vehicle. The downshifting of the transmission takes advantage of a braking action of a driving motor connected to the automatic transmission through a clutch, are terminated by the closing of a clutch during a compression phase lasting until the achievement of a predetermined threshold speed. For the improvement of the immediacy of the vehicle drive after the termination of the compression phase, the invention provides that at speeds less than the threshold speed, downshifting is carried out and is terminated with an open clutch.
摘要:
A method of controlling an automatic transmission of a motor vehicle that is situated in the force flow between a drive motor and an axle drive of a drive axle or a transfer box in which the current road inclination (αFB) is determined. To improve the shifting behavior of the transmission, during a transition between driving on a downhill stretch (2) and on level ground (4), after driving on the downhill stretch (2) and/or after the transition to a thrust operation, a recognition function for determining a downhill run-out (3) is initiated and, when the downhill run-out (3) is recognized, a shift to a higher gear during a thrust operation, i.e., a thrust upshift, is carried out before driving onto level ground (4) and/or before the transition to the traction operation.
