    摘要： A belt type continuously variable transmission (CVT) (10) for a vehicle varies the speed ratio in accordance with the hydraulic pressure that is regulated via a hydraulic pressure regulating unit (30). A sensor (27) detects a vehicle speed. A CVT controller (20) calculates a target hydraulic pressure that is supplied to the CVT (10) on the basis of a predetermined speed change schedule so that the speed ratio varies in the direction of up-shifting as the vehicle speed increases (S15). The CVT controller (20) also determines whether or not a specified condition holds (S16, S160), and controls the hydraulic pressure regulating unit according to a target start-up hydraulic pressure which is larger than a target hydraulic pressure for normal running (S11, S13), thereby preventing a speed change lag when the vehicle starts to move.

    摘要： There is provided a V-belt continuously variable transmission (10) including: a primary pulley (11) that is connected to an input shaft (11d); a secondary pulley (12) that is connected to an output shaft (12d); a V-belt (13) that is wrapped around the primary pulley (11) and the secondary pulley (12); and controllers (20, 30). When a speed ratio is to be increased, the oil pressure supplied to the primary pulley (11) is set to an oil pressure necessary for ensuring a torque capacity of the V-belt (13) and necessary for maintaining the speed ratio, and the oil pressure supplied to the secondary pulley (12) is set to an oil pressure that is higher than the oil pressure necessary for ensuring the torque capacity of the V-belt (13) and necessary for maintaining the speed ratio, thereby attaining a target speed change speed.

    摘要： A control apparatus for an automatic transmission includes a control section (12a) having a target secondary pressure setting section (12c) configured to set a target secondary pressure (Pt sec) within a strength limit of the belt, and an operation switching section (P2,P3) configured to switch a shift operation from a normal speed to a high speed higher than the normal speed when a predetermined condition is satisfied. The control section (12a) is configured to control the secondary pressure regulating valve by a feedback control based on the target secondary pressure (Pt sec) and the actual secondary pressure (P sec) sensed by the hydraulic pressure sensor. The target secondary pressure setting section is configured to modify the target secondary pressure by adding a predetermined quantity when a correction initiation condition is satisfied, the condition initiation including a first condition that the shift operation is performed at a high speed by switching of the operation switching section.
