To provide a control device for a belt type continuously variable transmission for a vehicle capable of suppressing the deterioration of the durability of a belt by restraining the belt from slipping at starting the vehicle.
The transmission 20 is composed of a pulley 231 for an input to which a driving force of the internal combustion engine 10 is transmitted and a pulley 232 for an output drivingly connected with wheels 12L, 12R and the belt 233 wound around the pair of pulleys 231, 232. The transmission 20 is provided with a hydraulic mechanism 230 for changing groove widths Win, Wout of the respective pulleys 231, 232 and a clutch 22a for adjusting a driving force transmitted to the pulley 231 for an input. When engaging the clutch 22a based on a shifting operation for starting the vehicle, a hydraulic pressure rising process for temporarily increasing hydraulic pressure supplied to at least one of the pair of pulleys 231, 232 from the hydraulic mechanism 230 is executed.
