摘要： A speed ratio of a continuously variable transmission mechanism 20 is increased when a speed ratio of a subtransmission mechanism 30 connected in series to the continuously variable transmission mechanism 20 is switched from a first speed to a second speed. When an excess rotation speed Nb obtained by subtracting a target rotation speed from an engine rotation speed Ne exceeds a determination value Nr1 during this shifting process, a rapid rotation increase in an internal combustion engine 1 is prevented by reducing a shift speed of the continuously variable transmission mechanism 20 (S105A).

摘要： When a through speed ratio, which is an overall speed ratio of a variator and a subtransmission mechanism, varies from a larger speed ratio than a mode switch speed ratio to a smaller speed ratio than the mode switch speed ratio, a gear position of the subtransmission mechanism is changed from a first gear position to a second gear position and the speed ratio of the variator is modified to a large speed ratio side. The mode switch speed ratio is set midway between a low speed mode Highest speed ratio and a high speed mode Lowest speed ratio.

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.
