    摘要: The shift control apparatus for a continuously-variable transmission includes; a primary pulley; a secondary pulley connected with the primary pulley by a belt; a shift actuator adapted to vary a speed ratio; a line pressure adjusting section configured to adjust a line pressure; a secondary-pressure adjusting section configured to adjust a secondary pressure; and a control section configured to control the shift actuator, the line pressure adjusting section, and the secondary-pressure adjusting section. Moreover, the control section includes a fail determining section configured to determine whether the shift actuator is under a failed condition. The control section is configured to carry out a fail-safe shift-actuator fixing control to fix the shift actuator, when the fail determining section determines that the shift actuator is under the failed condition, and is configured to carry out a fail-safe hydraulic control to bring the line pressure to its upper limit pressure and bring the secondary pressure to its maximum pressure, when a control-start criterion predetermined to secure driving performance of the vehicle is satisfied under the failed condition.

    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.
