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.
