A belt-type continuously variable transmission CVT is equipped with a belt 44 wrapped around across a primary pulley 42 and a secondary pulley 43, and a CVT control unit 81 for controlling pulley hydraulic pressures to the primary pulley 42 and the secondary pulley 43. The CVT control unit 81 determines whether an operating state is a driving state where the direction of an input torque inputted to the belt-type continuously variable transmission CVT is from a driving source (engine 1, motor generator 2) or a coasting state where the input torque direction is from front-left and front-right road wheels 6, 6. The pulley hydraulic pressure for the input torque for when it is determined that the operating state is the coasting state is set higher than the pulley hydraulic pressure for the input torque for when it is determined that the operating state is the driving state, thereby suppressing a slippage of the belt.
