Patent ID: 8241178

Claim:
A continuously variable transmission installed in a vehicle, comprising: a variator capable of varying a speed ratio continuously; a subtransmission mechanism provided 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 coordinated shifting unit which, when a gear position of the subtransmission mechanism is changed, performs a coordinated shift in which the subtransmission mechanism is shifted and the variator is shifted in an opposite direction to a speed ratio variation direction of the subtransmission mechanism; and a non-coordinated shifting unit which, when a rapid deceleration is performed in a situation where the second gear position is selected by the subtransmission mechanism, downshifts the subtransmission mechanism from the second gear position to the first gear position and downshifts the variator without performing the coordinated shift.
