    摘要: A control device for a vehicle continuously variable transmission 4 includes: final speed ratio setting means for setting an overall speed ratio of the continuously variable transmission mechanism 20 and the subtransmission mechanism 30 to be reached on the basis of an operating condition of the vehicle as a final speed ratio; shift control means for controlling the continuously variable transmission mechanism 20 and the subtransmission mechanism 30 such that the overall speed ratio aligns with the final speed ratio at a predetermined transient response; stagnation determining means for determining whether or not a stagnation period in which the overall speed ratio stops varying will occur during an upshift; and reduction control means for shortening a time required to advance to an inertia phase from a start of a shift in the subtransmission mechanism 30 following a determination that the stagnation period will occur.

    摘要: A continuously variable transmission 4 for a vehicle includes a variator 20 that modifies a speed ratio continuously and a subtransmission mechanism 30 that is connected in series to the variator 20 and applies a first speed and a second speed, which is higher than the first speed, selectively. When the vehicle is running under a low load/high speed upshift condition having a lower load or a higher speed than a normal upshift condition, the subtransmission mechanism 30 is upshifted from the first speed to the second speed at a lower vehicle speed than under the normal upshift condition, and as a result, both rotation variation in an internal combustion engine 1 accompanying upshifting of the subtransmission mechanism 30 and an increase in a fuel consumption amount of the internal combustion engine 1 due to the shift operation in the continuously variable transmission 4 are suppressed.

    摘要: A subtransmission mechanism 30 comprises a Ravigneaux planetary gear mechanism 31, a Low brake 32 and a High clutch 33, shifts between a first speed gear position in which the Low brake 32 is engaged whereas the High clutch 33 is disengaged and a second speed gear position in which the Low brake 32 is disengaged and the High clutch 33 is engaged. A minute slip is caused at the Low brake 32 and then terminated by engaging the High clutch 33. A value representing the engaging state variation such as an engaging time period and/or an engaging speed of the High clutch 33 is learned and the pressure of oil supplied during the engaging operation of the High clutch 33 is corrected based upon the learned value, thereby assuring a smooth shift operation by compensating for any inconsistency in the torque transmission characteristics of the High clutch 33.
