摘要： The present invention relates to a device for controlling an automatic transmission including a first frictional engagement element that is engaged at a first gear shift stage and is released at a second gear shift stage. When a request for a gear shift from the second gear shift stage to the first gear shift stage during a gear shift from the first gear shift stage to the second gear shift stage is present, occurrence of a shock and an engine rotation rise is suppressed. After the gear shift from the first gear shift stage to the second gear shift stage is finished (S1), a stroke rate of a piston that is actuated to press friction discs of the first frictional engagement element is calculated (S2), and the stroke rate calculated is compared with a predetermined stroke threshold value (S3). When the stroke rate calculated becomes equal to or smaller than the stroke threshold value, the gear shift from the second gear shift stage to the first gear shift stage is started.

摘要： -- Under a specified condition where a torque converter is kept in a lockup state to prolong the fuel-cutoff time, because of vehicle coasting with an accelerator opening APO=0, a downshift command is generated and then an automatic transmission causes a reengagement downshift by a drop in a release-side clutch hydraulic pressure Poff and a rise in an engagement-side clutch hydraulic pressure Pon. During the reengagement downshift, the engagement-side clutch hydraulic pressure Pon is reduced from a high lockup-ON hydraulic pressure to a low lockup-OFF hydraulic pressure after the time when the lockup is predicted to be released, thus preventing a torque drawing-in tendency of Transmission output torque, which may occur at the time of the beginning of the inertia phase, from increasing, and also reducing in the width of a subsequent change in vehicle deceleration G, and consequently enhancing the shift quality. --

摘要： [Abstract] In a control apparatus for an automatic transmission in which a first frictional clutching element which is engaged at a first gear shift stage and which is released at a second gear shift stage is equipped, when, during a gear shift from the first gear shift stage to the second gear shift stage, automatic transmission means (9A) for executing the gear shift to the gear shift stage automatically set on a traveling state issues a request of the gear shift from the second shift stage to the first gear shift stage before a start of an inertia phase during the gear shift from the first gear shift stage to the second gear shift stage, this gear shift request is inhibited. On the other hand, during the gear shift from the first stage to the second gear shift stage, before the start of the inertia phase, manual transmission means (9B) for executing the gear shift to the gear shift stage set through a manual operation issues another request of the gear shift from the second gear shift stage to the first gear shift stage, this gear shift request is allowed. Thus, while generations of a shock and a racing are prevented from occurring, a gear shift control in accordance with a driver intention can be executed.
