Abstract
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.
