摘要： When the speed ratio of a belt-type continuously variable transmission is equal to or larger than a predetermined threshold value, switching between a first power transmission path including a gear transmission mechanism and a second power transmission path including a belt-type continuously variable transmission is performed by means of clutches, so as to reduce a difference in an input shaft rotational speed applied to the clutches before and after the switching.

摘要： Provided is a control device of an automatic transmission, by which a supercharger can be prevented from becoming high in temperature and deteriorating in durability. An automatic transmission is connected to an engine (1) in which a supercharger (2) is mounted and has a manual mode to manually select a desired gear ratio from a plurality of fixed gear ratios. A control device includes a manual mode detection unit, a temperature judgment unit (31) and a gear ratio changeover unit (43) arranged such that, when the manual mode detection unit detects that the automatic transmission is in the manual mode and when the temperature judgment unit judges that the temperature of the supercharger is higher than or equal to a predetermined value, the gear ratio changeover unit changes the gear ratio of the automatic transmission to a higher gear ratio and thereby lowers the rotation speed of the engine (1).

摘要： An automatic transmission control apparatus includes an engine rotational speed limit verifying section and a shift control characteristic changing section. The engine rotational speed limit verifying section is configured to receive an engine rotational speed limit value for limiting an engine rotational speed and determine if the engine rotational speed limit value is lower than a prescribed normal upper limit value. The shift control characteristic changing section is configured to change a shift schedule of an automatic transmission based on the engine rotational speed being limited by the engine rotational speed limit value and the automatic transmission having a stronger tendency to select a higher gear stage than if the engine rotational speed limit value was not being limited to a lower value than the prescribed normal limit value, when the engine rotational speed limit value is determined to lower than the prescribed normal upper limit value.

摘要： A control strategy and method for controlling friction element engagement and disengagement time for an automatic transmission when the transmission is operating at cold ambient temperatures. During drive-to-reverse or reverse-to-drive friction element engagements with power on, the strategy compensates for a tendency of an oncoming friction element to gain capacity before an off-going clutch loses capacity, thereby avoiding a potential friction element tie-up condition when the transmission is operated with intermediate or high levels of engine torque as the friction elements are sequentially engaged and disengaged during cold rock cycling.
