PROBLEM TO BE SOLVED: To properly control a belt clamping force of a belt-type continuously variable transmission, and an oil pressure of a hydraulic frictional engagement device capable of changing torque acting on the continuously variable transmission according to an engagement pressure, while associating them with each other.SOLUTION: A hydraulic control device of a belt-type continuously variable transmission configured to control engagement of a clutch disposed between an internal combustion engine and the belt-type continuously variable transmission, to control a belt clamping force to clamp a transmission belt according to a torque input to the belt-type continuously variable transmission, and further to execute correction control to correct a hydraulic command value of the clutch in an engagement transition period for engaging the clutch from a released state, and driving the internal combustion engine, includes clamping force control means controlling the belt clamping force while applying a hydraulic pressure command value of the clutch before corrected by the correction control, as an input value, in executing the correction control (step S3). |
