Abstract: The lock-up control unit is configured to: in a case where the normal mode is selected, disengage the lock-up clutch when a vehicle speed decreases and reaches a first vehicle speed while the vehicle is traveling in a state where the lock-up clutch is engaged, in a case where the eco mode is selected, disengage the lock-up clutch when the vehicle speed decreases and reaches a second vehicle speed in a brake operation OFF state while the vehicle is traveling in the state where the lock-up clutch is engaged, in the case where the eco mode is selected, disengage the lock-up clutch when the vehicle speed decreases and reaches a third vehicle speed in a brake operation ON state while the vehicle is traveling in the state where the lock-up clutch is engaged, and set the third vehicle speed to a vehicle speed lower than the first vehicle speed, and set the second vehicle speed to a vehicle speed higher than the first vehicle speed.

Abstract: A control device for an automatic transmission in a vehicle with a constant speed travel mode includes: a determination section that determines whether the vehicle is traveling on a slope road; a slope adaptation control section that implements a first transmission shift control if not traveling on a slope road and, if traveling on a slope road, implements a second transmission shift control for selecting a transmission shift position of a lower speed than case of not traveling on a slope road; a delaying section that, upon switching from the second transmission shift control to the first transmission shift control, implements an upshift delay control for performing upshift one by one at a predetermined time interval; and a setting section that, in case of traveling at the constant speed travel mode, sets the time interval shorter in comparison with case of traveling not at the constant speed travel mode.

Abstract: A control device for an automatic transmission arranged between an engine and a drive wheel, the automatic transmission including a torque converter having a lock-up clutch, and a transmission mechanism. The control device includes a shift control unit configured to perform shift control of the transmission mechanism. The shift control unit includes a forced downshift control processing unit configured to implement forced downshift when an accelerator foot release operation is performed during auto-upshift in a power-on state with the lock-up clutch engaged. The forced downshift control processing unit is configured to start the forced downshift before an engine rotation speed that has decreased due to the auto-upshift reaches a lock-up release rotation speed.

Abstract: A control apparatus includes a shift-pressure learning correction controlling section configured to perform a shift-pressure learning correction in which a physical quantity representing a progress of shift is measured at a time of a current downshift, and in which an engagement command pressure for a friction element is corrected at a time of a next downshift on the basis of a divergence between the measured physical quantity and a target physical quantity; a shift-torque increase controlling section configured to perform a torque increase control in which a command for temporarily increasing torque of a drive source starts to be outputted when a start estimation timing of torque phase has just come during a transition period given between start and end of the downshift; and a learning convergence judging section configured to judge whether the shift-pressure learning correction has converged.
