Abstract
When a line pressure is dominated (determined) by at least one of a primary pressure and a secondary pressure during idling of a continuously variable transmission, the hydraulic pressure that is applied to at least one of pulleys, to which the hydraulic pressure larger than a clutch pressure is applied, is reduced. On the other hand, when the line pressure is dominated by the clutch pressure during idling of the continuously variable transmission, the speed gear ratio of the continuously variable transmission is controlled to a lowest speed gear ratio.
