摘要： A control for a continuously variable transmission includes a wheel speed sensor (21F) arranged to sense a rotation speed of a driving wheel, a wheel speed sensor arranged to a rotation speed of a driven wheel, and a transmission controller (12). The transmission controller (12) is configured to judge a traveling road is a rough road (S1) when a wheel speed difference between the driving wheel and the driven wheel is equal to or greater than an entering judgment threshold value, and to increase a clamping force of the continuously variable transmission (1). The transmission controller (12) is configured to sense a vibration of a vehicle speed based on the detection value of the wheel speed sensor (21R), and to decrease the increased clamping force when the wheel speed difference is equal to or smaller than a release judgment threshold value (S3), and when the sensed vibration is equal to or smaller than a predetermined vibration value (S5).

摘要： In an automatic transmission control device of the invention configured to start an increase in engagement pressure of a start-up engagement element, when a determination threshold value (X1) for determining that a turbine rotational speed (Nt) has reduced is reached or exceeded, the determination threshold value (X1) when a selection operation from a non-traveling range to a traveling range is made before a prescribed period of time (T1) from starting of an engine has elapsed, is increased and set greater than the determination threshold value when the selection operation is made after the prescribed period of time (T1) has elapsed. Accordingly, a reduction in turbine rotational speed (Nt) can be accurately determined, and thus it is possible to suppress torque fluctuations, occurring owing to engagement of a second brake (B2), which is the start-up engagement element.

摘要： A system and method for controlling double transition shifts in an automatic transmission having multiple gear sections. During a double transition shift, the system performs simultaneous closed loop control of the primary oncoming clutch in the primary gear section and the secondary off-going clutch of the secondary gear section. Before the input shaft of the secondary gear section is fully pulled down or the secondary off-going clutch becomes overheated, the system switches closed loop control of the input shaft to the secondary on-coming clutch of the secondary gear section. The system utilizes model-based calculations to determine the initial clutch pressure settings when a clutch enters closed loop control.
