Abstract: A method for operating a transmission of a vehicle drivetrain. A transmission ratio can be automatically changed during an operating state depending on a comparison of current operating state parameters with operating parameters stored in a control unit, and can be manually changed depending on a driver's request. Accordingly when the driver requests a change of the transmission ratio, the transmission ratio changes, and a timer starts. If the driver continues the ratio change from an actual transmission ratio value toward a larger or smaller transmission ratio value, the current operating parameters are compared with the stored operating parameters. Upon this comparison, the transmission shifts to higher ratios in comparison to the operating parameters stored in a control device at higher vehicle speeds, and/or a delay between sequential, cyclical transmission ratio changes varies depending on a vehicle deceleration and/or braking pressure in the region of a vehicle brake.

Abstract: A method is provided for controlling an automatic transmission of a motor vehicle, in which the engine speed is limited after a cold start and a normal shift point is used for shifting to the next higher gear of the automatic transmission in the case of an average operating temperature of an engine, before the average operating temperature is reached, a cold shift point being used for shifting to the next higher gear of the automatic transmission, in the case of which upshifting is performed at a lower vehicle velocity than in the case of the normal shift point. Upshifting into the next higher gear of the automatic transmission can be made easier, since upshifting can already be performed at lower vehicle velocities and therefore lower engine speeds in the cold start phase.

Abstract: A vehicular shift control device is provided that controls the input rotational speed of a geared transmission by adjusting the rotational speed of a drive source at downshift of the geared transmission. The greater the deceleration of the vehicle, the smaller is set the change gradient of the input rotational speed of the geared transmission. Therefore, even if the decrease rate of the post-shifting synchronization rotational speed is great, the incident angle ? of the input rotational speed of the geared transmission relative to the post-shifting synchronization rotational speed is maintained as a large angle. Even when the deceleration of the vehicle during downshift is great, the downshift is smoothly executed without producing an excessive synchronization shock.

Abstract: In a downshift of an automatic transmission in a state where an accelerator pedal is depressed, one of a clutch-to-clutch shift in which the shift is carried out by gradually reducing an engagement pressure of a clutch or a brake to be disengaged in the shift and a rotation synchronization shift in which the shift is carried out by reducing the engagement pressure of the clutch or the brake more quickly than in the clutch-to-clutch shift is selected based on an output shaft torque of the automatic transmission, a region where the rotation synchronization shift is selected is lower in output shaft torque than a region where the clutch-to-clutch shift is selected, and hence it is possible to appropriately selectively execute a shift placing emphasis on a shock and a shift placing emphasis on a shift speed in accordance with the output shaft torque.
