Abstract: A method of down-shifting a transmission avoids output shaft oscillations by briefly increasing the torque capacity of an off-going element at the end of the inertia phase. The torque capacity of the off-going element is then reduced to zero when the measured transmission speed ratio begins to decrease. The method is suitable for downshifts that involve multiple off-going elements and multiple on-coming elements such as a shift from tenth gear to sixth gear in a ten speed transmission.

Abstract: A control device configured to control a vehicle. When the required driving force is equal to or less than a control judgment value, the shift control section judges that an implementing condition of engagement limited downshift control is met, starts transition control to cause the release-side engagement device to transition to a non-direct-coupled engagement state and, after the release-side engagement device transitions to a non-direct-coupled engagement state, starts increasing rotation speed control to control rotation speed of the input member to be higher than synchronized rotation speed, starts differential rotation speed control to control the rotation speed to be higher than the synchronized rotation speed, and prohibits engagement of the engagement-side engagement device until it becomes higher than the synchronized rotation speed.

Abstract: The rate of change of transmission output torque is computed based on the differential speeds of the axles and of the transmission output shaft adjusting for final drive ratio. The speed of the axle is measured by an anti-lock braking system and communicated to the transmission controller over a communications bus. To compensate for the delay introduced by the communications bus, a shift register delays the signal from the transmission output shaft speed sensor. The resulting estimate of rate of change of transmission output torque may be used directly to control the torque capacity of one or more transmission clutches. Additionally, the resulting estimate may be combined with an independent output torque estimate to yield a more accurate output torque estimate.

Abstract: An unlock operation of a lockup clutch and a shift-up operation of an automatic transmission are performed together when an accelerator pedal of a vehicle is released in a state where the lockup clutch is in a lockup state. An engine rotation speed immediately after the shift-up operation is estimated on the basis of the engine rotation speed and a gear ratio of the automatic transmission after the shift-up operation. If a fuel recovery operation is predicted to be performed immediately after the shift-up operation, the fuel-cut operation is prevented, thereby suppressing a shock from occurring due to the fuel recovery when a foot release shift-up operation is performed.
