    摘要： A continuously variable transmission includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). When an actual through speed ratio passes a predetermined mode switch speed ratio, a transmission controller (12) performs a coordinated shift in which a gear position of the subtransmission mechanism (30) is changed and a speed ratio of the variator (20) is varied in an opposite direction to a speed ratio variation direction of the subtransmission mechanism (30). When the rapid deceleration is determined to be underway, the transmission controller (12) decreases a speed ratio variation amount of the variator (20) in the direction of a High side accompanied by a downshift of the subtransmission mechanism (30) compared with the coordinated shift.

    摘要： A continuously variable transmission (4) includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). On the basis of an operating condition of a vehicle, a transmission controller (12) sets a destination through speed ratio (DRatio), which is an overall speed ratio of the variator (20) and the subtransmission mechanism (30) to be realized in accordance with the operating condition, and controls the variator (20) and the subtransmission mechanism (30) on the basis thereof. When shifts are prohibited in the subtransmission mechanism (30), the destination through speed ratio (DRatio) is limited to a speed ratio range that can be realized only by a shift in the variator (20).

    摘要： A control system controls an automatic transmission. The automatic transmission comprises a stepwise variable transmission section that includes a plurality of frictional elements and establishes a desired speed by a shift change disengaging one of the frictional elements and engaging the other of the frictional elements and a continuously variable transmission section that establishes a desired speed continuously. The control system makes a speed change control of the continuously variable transmission section cooperate with a change of an input rotation speed of the stepwise variable transmission section. The control system is configured to carry out during the shift change of the stepwise variable transmission section, judging whether a delivery of a torque from a disengaging side frictional element to an engaging side frictional element is completed or not; and starting the speed change control of the continuously variable transmission section upon judgment of the completion of the delivery of the torque regarding that an inertial phase has started.
