摘要： In a transmission, a controller sets a target line pressure to an offset target value, which is a value obtained by adding a positive offset amount to one of a target PRI pressure and a target SEC pressure, in a speed ratio range in which the offset target value is higher than the other at least during an inertia phase in a sub-transmission mechanism when a coordinated shift is carried out. At that time, the one of the target PRI pressure and the target SEC pressure is the target SEC pressure when a variator is downshifted by the coordinated shift while being the target PRI pressure when the variator is upshifted by the coordinated shift.

摘要： A transmission controller executes synchronization shift of shifting a variator in a direction opposite to a speed ratio change direction of a sub transmission mechanism when shifting a sub transmission mechanism. When a gear position of the sub transmission mechanism is at the second gear position and an output increase request of a power source is made, the transmission controller prohibits the synchronization shift and shifts only the sub transmission mechanism from a second gear position to a first gear position.

摘要： In a control apparatus for an automatic transmission including a continuously variable transmission mechanism continuously modifying speed ratio and a stepped transmission mechanism that is disposed on a downstream side of the continuously variable transmission mechanism and being switched between a plurality of gear positions by engaging and disengaging a plurality of frictional engagement elements, the control apparatus comprises a control unit that performs a coordinated shift by shifting the stepped transmission mechanism and simultaneously shifting the continuously variable transmission mechanism in an opposite direction to a shift direction of the stepped transmission mechanism in order to suppress variation in a through speed ratio, which is an overall speed ratio of the automatic transmission, when the stepped transmission mechanism is upshifted and the control unit predicts, on the basis of an increase in an accelerator opening, that judder will occur in the frictional engagement element during the upshift, the control unit reduces a shift speed of the continuously variable transmission mechanism while shudder is predicted to occur in the frictional engagement element in comparison with a shift speed of the continuously variable transmission mechanism during the coordinated shift, the coordinated shift being executed at an accelerator opening corresponding to the increased accelerator opening.

摘要： A transmission includes a sub-transmission mechanism, a variator having lower shift responsiveness than the sub-transmission mechanism, and a controller configured to carry out a coordinated shift for changing a speed ratio of the variator in a direction opposite to a changing direction of a speed ratio of the sub-transmission mechanism as the sub-transmission mechanism is shifted so that a through speed ratio reaches a target through speed ratio. The controller sets a target speed ratio of the sub-transmission mechanism on the basis of the target through speed ratio and an actual speed ratio of the variator in carrying out the coordinated shift.
