摘要： A control device includes a belt slip controller, a limiting determining control unit, and a transmission speed limiter. The device controls a vehicle belt type continuously variable transmission including a primary pulley and a secondary pulley so as to control a gear ratio by controlling a primary hydraulic pressure and a secondary hydraulic pressure. The controller oscillates the secondary hydraulic pressure, extracts an oscillation component of an actual gear ratio when a transmission speed is less than a predetermined value, and controls the secondary hydraulic pressure based on a phase difference between oscillation components. The determining control unit determines whether to limit acceleration, and the limiter limits a transmission speed to less than the predetermined value when the determining control unit makes a determination to limit the acceleration. The controller permits belt slip control while the limiter limits the transmission speed to less than the predetermined value.

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 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.
