Abstract

See full text

A belt-type continuously variable transmission is equipped with a belt wrapped around across a primary pulley and a secondary pulley, and a CVT control unit for controlling pulley hydraulic pressures to the primary pulley and the secondary pulley. The CVT control unit determines whether an operating state is a driving state where the direction of an input torque inputted to the belt-type continuously variable transmission is from a driving source or a coasting state where the input torque direction is from drive road wheels. 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.
