Patent ID: 8403809

Claim:
A continuously variable transmission installed in a vehicle, comprising: a variator capable of varying a speed ratio continuously; a subtransmission mechanism in series with the variator and having a first gear position and a second gear position, the second gear position having a smaller speed ratio than the first gear position, as forward gear positions; a shift control unit which controls at least one of the speed ratio of the variator and a gear position of the subtransmission mechanism on a basis of an operating condition; a coordinated shifting unit which changes the gear position of the subtransmission mechanism and varies the speed ratio of the variator in an opposite direction to a speed ratio variation direction of the subtransmission mechanism on a basis of a relationship between the operating condition and a mode switch line on a shift map; and a shift time reducing unit which reduces an amount by which the speed ratio of the variator is varied when the operating condition has passed the mode switch line on the shift map from a Low side to a High side.
