摘要： Provided are a variator (20) and a transmission controller (12) in an engine-driven vehicle. The transmission controller (12) has an instantaneous interruption recovery control portion ( FIG. 4 ) configured to, upon a power reset from an instantaneous interruption during running, set a target through transmission ratio (vRATIO0) and a desired through transmission ratio (vDRATIO) to a lowest transmission ratio value by initialization and perform recovery control to recover an actual through transmission ratio (vRATIO) of the variator (20) to a transmission ratio value for shifting to normal control. The instantaneous interruption recovery control portion ( FIG. 4 ) 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 (vRATIO0) from the lowest transmission ratio value to the desired through transmission ratio (vDRATIO), to be higher than that under the normal control, before a time at which the desired through transmission ratio value (vDRATIO) deviates from the lowest transmission ratio value.

摘要： 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.

摘要： The present invention is related to a vehicle including a motor-generator (2), a transmission (4), a shift hydraulic control unit (7), and a CVT control unit (CVTCU (81)). 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 (43) 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 (81) also sets a pulley thrust at a primary pulley (42) 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.

摘要： 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.
