    摘要: One of two clutches etc. engaged concurrently with each other to establish a second speed, a third speed, or a fourth speed is determined in advance as an abnormal-time engagement element that is kept engaged when an abnormality occurs in which one different clutch or brake is engaged during concurrent engagement of the two clutches etc. The other of the two clutches etc. is determined in advance as an abnormal-time slipping element that is caused to slip when such an abnormality occurs. During concurrent engagement of the two clutches etc., a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time engagement element is set to be higher than a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time slipping element.

    摘要: A control device for controlling a transmission configured such that when the speed change mechanism performs switching to a shift speed with a lower speed ratio in a negative torque prediction established state in which predicted input torque is negative, the predicted input torque being a predicted value of input torque input to the input member a predetermined determination reference time later, and being derived on the basis of variations in the input torque, special speed change control is executed in which a disengagement hydraulic pressure is lowered to cause a disengagement element to slip, and the disengagement element is maintained in a slipping state over an entire speed change process, which extends from a time point when the disengagement element starts slipping to a time point when a rotational speed is synchronized with a rotational speed of the input member.

    摘要: A control device includes a differential rotation obtaining unit; a direct-coupling control unit that decreases the differential rotation speed by increasing an engagement pressure of the direct-coupling clutch at a normal pressure increase rate determined depending on a traveling state of a vehicle so as to change the direct-coupling clutch from a released state to an engaged state; and a pressure increase control unit that changes to a rapid pressure increase rate larger than the normal pressure increase rate for increasing the engagement pressure by the direct-coupling control unit when the differential rotation speed becomes equal to or smaller than a predetermined pressure increase permission threshold in a state that an accelerator opening of the vehicle decreases.

    摘要: A shift controller controls a downshift to a low shift speed, spaced apart from a high shift speed by two or more steps, through an intermediate shift speed, by first releasing first and second shift release elements, then engaging a first shift engagement element, and finally engaging a second shift engagement element, while controlling the torque capacity of the second shift release element by feedback control. As a result of releasing the first and second shift release elements before engaging the first shift engagement element, it is possible to rev up an input rotation at maximum performance of an engine to reduce the time for shifting. As a result of the feedback control of the torque capacity of the second shift release element after engaging the first shift engagement element, a torque fluctuation at the intermediate shift speed can be reduced to avoid occurrence of an uncomfortable shift shock.

    摘要: A device with a stepped automatic transmission to transfer power from a power source to an axle using changeable shift speeds includes an input-side fluid transmission element connected to the power source, an output-side fluid transmission element connected to the transmission input shaft, a lock-up clutch engaging and disengaging the input-side and the output-side fluid transmission elements; a unit adjusting the lock-up clutch; a unit setting, when a downshift is to be performed in response to a predetermined request for a large drive force, a predetermined target slip speed value larger than a non-shifting-time value before a rotational speed of the power source exceeds a input shaft rotational speed after the downshift, and setting the target slip speed to decrease toward the non-shifting-time value along with lapse of time after the power source rotational speed source exceeds the post-shifting input shaft speed; and a unit controlling the engagement force so the slip speed becomes the set target slip speed. The target slip speed is a difference between the rotational speeds of the power source and the input shaft, and the non-shifting-time value is set when no shifting is performed.
