Abstract: A continuously variable transmission includes a variator capable of varying a speed ratio continuously, and a subtransmission mechanism provided in series with the variator. When an actual through speed ratio passes a predetermined mode switch speed ratio, a transmission controller performs a coordinated shift in which a gear position of the subtransmission mechanism is changed and a speed ratio of the variator is varied in an opposite direction to a speed ratio variation direction of the subtransmission mechanism. When the rapid deceleration is determined to be underway, the transmission controller decreases a speed ratio variation amount of the variator in the direction of a High side accompanied by a downshift of the subtransmission mechanism compared with the coordinated shift.
