摘要： A control device that controls an automatic transmission is provided, in which device the automatic transmission includes a variator disposed in a power transmission path between a driving source and a driving wheel of a vehicle, and a friction engaging element disposed between the variator and the driving wheel, in a manner capable of transmitting a power disconnectably via the power transmission path. The control device increases a speed ratio of the variator toward a predetermined target speed ratio with disengaging the friction engaging element during a vehicle stop of the vehicle, and executes a learning regarding a hydraulic control of the friction engaging element when the friction engaging element is disengaged during the vehicle stop. The control device decreases the target speed ratio at a time of learning when the learning is executed during the vehicle stop, compared to a time of vehicle stop other than the time of learning.

摘要： A clutch control device that controls a clutch by driving a piston using a working fluid, having: stroke start determining means (S1) for determining that a stroke of the piston has started and detecting a stroke start oil pressure at that time; stroke end determining means (S4) for determining that the stroke of the piston is complete and detecting a stroke end oil pressure at that time; stroke end range estimating means (S3) for estimating a range of the stroke end oil pressure from the stroke start oil pressure detected by the stroke start determining means; and learning means (S5, S6) for learning the stroke end oil pressure detected by the stroke end determining means when the stroke end oil pressure is within the estimated range of the stroke end oil pressure. Learning precision of the stroke end oil pressure can be improved.

摘要： A continuously variable transmission for a vehicle according to the present invention includes a transmission controller (12) configured to perform a variator (20) and an auxiliary transmission (30), a line pressure regulating valve (11a), a primary pressure regulating valve (11b), and a secondary pressure regulating valve (11c). The transmission controller (12) includes a line pressure control section ( FIG. 4 ) configured to increase a line pressure (PL) to be greater than the line pressure before the generation of the oil vibration when the oil vibration is generated in at least one of the primary pressure (Ppri) and the secondary pressure (Psec). When the auxiliary transmission mechanism (3) is shifted in a state where the line pressure (PL) is increased, the line pressure section ( FIG. 4 ) is configured to continue the increase of the line pressure (PL) until the auxiliary transmission mechanism (30) is finished for attaining the stable shift.

摘要： In the present invention, there are provided with an auxiliary transmission mechanism (30) disposed in series with a variator (20), and having at least two or more forward gear stages; and a transmission controller 12 configured to increase the belt capacities to be greater than the belt capacity set when the accelerator opening degree (APO) is zero, at least in a time period from a timing when the accelerator opening degree APO becomes zero, to a timing when a braking force is generated by a depression of a brake pedal. The transmission controller (12) is configured to set an increase amount with respect to the belt capacity set when the accelerator opening degree (APO) is zero, to a smaller value as a transmission gear ratio of the auxiliary transmission mechanism (30) is higher.
