    摘要： A control device for a continuously variable transmission with an auxiliary transmission includes: a cooperative control section being configured to shift the auxiliary transmission mechanism during the first inertia phase time period, and to shift the variator during the second inertia phase time period, when the cooperative control in which an input torque to the continuously variable transmission is equal to or smaller than a predetermined value in the cooperative control is judged, and being configured to shift the auxiliary transmission mechanism during the first inertia phase time period, and to shift the variator during the first inertia phase time period when the cooperative control in which the input torque to the continuously variable transmission is greater than the predetermined value is judged.

    摘要： A transmission controller determines whether or not an input rotation speed of a sub-transmission mechanism is stagnant and executes a feedback control by adding a rotation speed change rate feedback correction amount caused by a difference between a target input rotation speed change rate and an actual input rotation speed change rate of the sub-transmission mechanism to a rotation speed feedback correction amount if the input rotation speed is determined to be stagnant.

    摘要： Disclosed is a control device for a continuously variable transmission (4) that has, as forward speed change stages, a first speed change stage (32) and a second speed change stage (33). The control device comprises a coordinated speed change means (12a) that carries out a coordinated speed changing in such a manner that when the speed change stage of an auxiliary transmission mechanism (30) is about to be changed, a speed change speed of the auxiliary transmission mechanism (30) is coordinated with a variator (20) and the variator (20) is controlled to carry out a speed change in a direction opposite to that of the auxiliary transmission mechanism (30) while carrying out the speed change operation of the auxiliary transmission mechanism (30), and a torque control means (12b) that carries out a torque regulating control during the coordinated speed changing under up-shifting by the coordinated speed change means, the torque regulating control being a control for effecting a torque-up operation to a driving source (1) after effecting a torque-down operation to the driving source and including a timing through which a starting time point of a drive force gap caused by the coordinated speed changing is advanced and a timing through which an ending time point of the drive force gap is delayed.
