Abstract
There is provided a control device for an automatic transmission capable of outputting a torque reduction signal for reducing the driving torque of a driving source during a transmission shift, in which, when a shift signal for an upshift is input with an accelerator opening equal to or more than a threshold and a transmission shift is performed, the torque reduction signal for reducing the driving torque of the driving source is output so that an inertial torque acting on an input shaft of a continuously variable transmission mechanism is canceled while a transmission shift ratio is changed and, before the transmission shift ends, a vehicle driving force is reduced to a vehicle driving force after the transmission shift.

7. A control device for an automatic transmission capable of executing a manual mode for performing a transmission shift in a stepwise manner on a continuously variable transmission mechanism continuously variable while drivably coupling a driving source to a wheel, the control device configured to receive a shift signal and configured to output a torque reduction signal for reducing a driving torque of the driving source during a transmission shift,
wherein, the controller is configured such that when the shift signal for an upshift is input with an accelerator opening equal to or more than a threshold and a transmission shift is performed, the torque reduction signal for reducing the driving torque of the driving source is output so that an inertial torque acting on an input shaft of the continuously variable transmission mechanism is canceled while a transmission shift ratio is changed and, before the transmission shift ends, a vehicle driving force is reduced to a vehicle driving force after the transmission shift.
