The controller includes a phase advance compensator which performs advance compensation of the indicating pressure, and a setting unit which sets an indicating pressure on which the advance compensation is performed by the phase advance compensator as the indicating pressure, in accordance with at least one of a rotation speed of a primary pulley, an input torque to a secondary pulley, a speed ratio, or a changing rate.

Control device of continuously variable transmission and control method of continuously variable transmission

The present invention is related to a vehicle including a motor-generator, a transmission, a shift hydraulic control unit, and a CVT control unit (CVTCU). When a downshift of the transmission is performed without an acceleration request from a driver, the CVTCU sets a pulley thrust at a secondary pulley on the basis of a first lower limit as a lower limit, which is a sum of a fundamental thrust and a first correction thrust. The CVTCU also sets a pulley thrust at a primary pulley on the basis of a second lower limit as a lower limit, which is a sum of the fundamental thrust and a second correction thrust.

Provided are a variator and a transmission controller in an engine-driven vehicle. The transmission controller has an instantaneous interruption recovery control portion configured to, upon a power reset from an instantaneous interruption during running, set a target through transmission ratio and a desired through transmission ratio to a lowest transmission ratio value by initialization and perform recovery control to recover an actual through transmission ratio of the variator to a transmission ratio value for shifting to normal control. The instantaneous interruption recovery control portion is further configured to, upon the power reset from the instantaneous interruption during the running, set a change speed of the target through transmission ratio from the lowest transmission ratio value to the desired through transmission ratio, to be higher than that under the normal control, before a time at which the desired through transmission ratio value deviates from the lowest transmission ratio value.

A hydraulic pressure controller includes belt sandwiching force increasing means. The belt sandwiching force increasing means increases a belt sandwiching force by a primary pulley and a secondary pulley on the basis of a braking force request from a driver, up to a predetermined value to prevent a belt from slipping due to a braking force. The belt sandwiching force increasing means increases the belt sandwiching force in a range of less than the predetermined value before the braking force request occurs.

A vehicle control device for controlling a vehicle including an oil pump driven by a transmission of a rotation of the motor-generator; and a hydraulic pressure supply unit for supplying a hydraulic pressure to the continuously variable transmission. The hydraulic pressure is generated by regulating a pressure of an oil discharged from the oil pump. When a regenerative braking is performed by the motor-generator based on a deceleration request from a driver, the hydraulic pressure supply unit supplies a hydraulic pressure based on a first hydraulic pressure and a second hydraulic pressure to the continuously variable transmission. The first hydraulic pressure is a hydraulic pressure to transmit an input torque input to the continuously variable transmission during the regenerative braking. The second hydraulic pressure is a hydraulic pressure to shift the continuously variable transmission during the regenerative braking. During the regenerative braking, the first hydraulic pressure is set to equal to or less than a hydraulic pressure found by subtracting the second hydraulic pressure from a hydraulic pressure suppliable to the continuously variable transmission.
