摘要： When a speed ratio (ip) at a stopping time of the vehicle cannot be stored, an operating position of a step motor (27) is initialized to a home position such that a primary pulley pressure (Ppri) is completely drained, a secondary pulley pressure (Psec) is increased to a predetermined pressure (P1), and a pulley ratio (the speed ratio (ip)) between a non-rotating primary pulley (2) and a non-rotating secondary pulley (3) is set at a lowest speed ratio. As a result, the primary pulley pressure (Ppri) is supplied reliably, and the startability of the vehicle improves.

摘要： A control method for a belt-type continuously variable transmission is provided for performing a belt slip control. The method includes oscillating hydraulic pressure and monitoring a phase difference calculated based on a multiplication value of an oscillation component in an actual hydraulic pressure and an oscillation component in an actual variable speed ratio to estimate a belt slip condition. The method further includes controlling hydraulic pressure to maintain a predetermined belt slip condition by reducing the hydraulic pressure to be lower than a hydraulic pressure in a normal control time based on an estimation, and limiting an input torque-change rate in which an input torque to the belt-type continuously variable transmission changes in an increasing direction until the hydraulic pressure rises to a hydraulic pressure in which the input torque is not excessive relative to a belt clamp force.

摘要： A control device controls a belt type continuously variable transmission including a primary pulley, a secondary pulley, and a belt, and controls a gear ratio based on a primary oil pressure and a secondary oil pressure. The control device includes a belt slip controller which oscillates the secondary oil pressure and monitors a phase difference between an oscillation component included in an actual secondary oil pressure and an oscillation component included in an actual gear ratio to estimate a belt slip state. The controller controls the actual secondary oil pressure to decrease based on the estimation to maintain a predetermined belt slip state. An oscillation amplitude setter sets an oscillation amplitude of the secondary hydraulic pressure small when the gear ratio is high compared with when the gear ratio is low, in a case of oscillating the secondary hydraulic pressure in the belt slip control.
