摘要： A control device for a continuously variable transmission of a vehicle includes a shift control section being configured to perform a rough road corresponding control to increase the hydraulic pressure to a value larger than the hydraulic pressure at a smooth road judgment at which the smooth road is judged, at a rough road judgment at which the rough road is judged, and when a line-pressure-up control condition is satisfied at the rough road judgment, the line pressure control section being configured to increase the line pressure to be greater than the line pressure when the line-pressure-up control condition is not satisfied.

摘要： There are provided a continuously variable transmission (CVT) in which a belt (7) is wound around a primary pulley (5) and a secondary pulley (6) to transmit power; a primary pulley rotational speed sensor (13) for detecting a rotational speed of the primary pulley (5); a vehicle stopped state determination means for determining whether a vehicle is in a stopped state; a belt slippage detection means for detecting belt slippage on the basis of a signal of the primary pulley rotational speed sensor (13); and a prohibition means for prohibiting detection of the belt slippage by the belt slippage detection means when a parking range or a neutral range is selected by a shift lever operation by a driver. In the vehicle stopped state during selection of the parking range or the neutral range, the rotational speed of the primary pulley (5) is not basically output, and the belt slippage does not occur. Thus, erroneous detection of the belt slippage can be avoided by prohibiting the detection of the belt slippage in this case.

摘要： A control device for a continuously variable transmission of a vehicle includes: a shift control section being configured to perform a rough road corresponding control to increase the hydraulic pressure supplied to the secondary pulley to a value larger than the hydraulic pressure at a smooth road judgment at which the smooth road is judged, at a rough road judgment at which the rough road is judged, and thereby to increase the clamping force of the secondary pulley with respect to the circular belt member; and a rotation speed control section being configured to control the transmission gear ratio at the rough road judgment so that a rotation speed of the primary pulley becomes equal to or greater than a lower limit rotation speed which is previously set.
