    摘要： The control device (70) comprises a condition setting portion setting a condition determining the control operation amounts using the shift model such that during a downshift performed during deceleration running associated with accelerator-off state, an engine (12) output torque is raised with the release-side engagement device released to increase an input rotating member (34) rotation speed toward a synchronous rotation speed after the downshift and such that the engagement-side engagement device is engaged; and a shift target value setting portion setting the torque target value at the output rotating member during the downshift such that the torque at the output rotating member is increased from a torque value at the output rotating member before the downshift within a zero-or-less range, and when an input rotating member (34) rotation speed approaches the synchronous rotation speed after the downshift, the target value is reduced toward a torque at the output rotating member after the downshift.

    摘要： An electronic control unit (5) is configured to set a target torque phase time which is used in torque phase control based on an output shaft torque difference. The electronic control unit (5) sets the target torque phase time to be longer when the output shaft torque difference is large than when the output shaft torque difference is small. Accordingly, since the target torque phase time can be appropriately set, it is possible to achieve both of preventing a sudden change in driving force and torsion vibration of an output shaft and preventing a decrease in drivability due to hesitation at the same time. Sudden change in driving force and torsion vibration of the output shaft occur when the difference in driving force between before and after a gear shift is large. Hesitation occurs when the difference in driving force between before and after the gear shift is small.

    摘要： A shift control device (70) of a vehicle (10) including an internal combustion engine (12) and a multi-speed transmission (22) in series, the shift control device comprising: a control portion (72, 74) providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up control of the internal combustion engine (12) toward a post-shift input shaft rotation speed in a neutral state where a release-side frictional engagement device to be released during a downshift of the multi-speed transmission (22) is released, so as to engage an engagement-side frictional engagement device to be engaged after the shift; and a torque setting portion setting a required torque of the internal combustion engine (12) in the torque-up control of the internal combustion engine (12) such that an increasing rate of an actual torque of the internal combustion engine becomes smaller in the case of a shift pattern having a large internal inertia of the multi-speed transmission during the downshift as compared to the case of a shift pattern in which the internal inertia is small.

    摘要： When an inertia phase has started while torque phase control is being executed, the torque phase control is ended, a target torque capacity of an engaging element in inertia phase control is corrected on the basis of a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element at the time when the torque phase control has completed (or a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element, which is set at the time when the inertia phase control has started), and the inertia phase control is started.

    摘要： Provided is a control device of a vehicle capable of suppressing a racing of input rotation speed and a shock of an automatic transmission occurring at the time of switching to a driving shift due to depression of an accelerator pedal etc. during a driven shift of the automatic transmission.
    When switching to a driving state is performed during an upshift in a driven state, an input rotation speed Nin of an input shaft 32 of an automatic transmission 22 is controlled by an engagement-side engagement device to be engaged during a shift and, in this case, an instruction pressure of the engagement-side engagement device is increased to a target surge pressure Psg for a target surge time T, so that the responsiveness of the engagement-side engagement device is enhanced. This enables the suppression of the racing of the rotation speed of the input shaft 32 and the shock due to a response delay of the engagement device.
