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 includes a sub-transmission mechanism (30), a variator (20) having lower shift responsiveness than the sub-transmission mechanism (30), and a controller (12) configured to carry out a coordinated shift for changing a speed ratio of the variator (20) in a direction opposite to a changing direction of a speed ratio of the sub-transmission mechanism (30) as the sub-transmission mechanism (30) is shifted so that a through speed ratio reaches a target through speed ratio. The controller (12) sets a target speed ratio of the sub-transmission mechanism (30) on the basis of the target through speed ratio and an actual speed ratio of the variator in carrying out the coordinated shift.
