摘要： A control device controls a belt type continuously variable transmission including a belt slip controller and a belt slip control permission determining unit. The device decreases belt friction when an estimated accuracy of a belt slip condition is high and prevents a belt from greatly slipping when an estimated accuracy is low. The device includes primary and secondary pulleys and the belt, and controls a gear ratio based on a running radius of the belt on a pulley by controlling primary and secondary oil pressures. The controller oscillates a secondary oil pressure, estimates the belt slip condition by monitoring a phase difference between oscillation components, and reduces an actual secondary oil pressure to maintain a predetermined belt slip condition. The determining unit permits belt slip control when a torque change speed input to the transmission mechanism is less than a predetermined value.

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.
