The present invention aims to provide a control device of an automatic transmission, which is able to reduce or improve a shift shock regardless of operation of an accelerator pedal by a driver. That is, the present invention provides a control device of an automatic transmission, which comprises a torque converter and a lock-up clutch which are arranged between an engine and an automatic transmission; and an up-shift control means that, when an up-shift is required with an accelerator pedal kept depressed by a driver, lowers an engaging capacity of releasing side engaging elements engaged at a speed stage before a gear shifting and then increases an engaging capacity of engaging side engaging elements engaged at a speed stage after the gear shifting thereby to establish a power-on up-shift, wherein the up-shift control means is configured in that when the acceleration pedal is released from the driver during the time when a power-on up-shift is being carried out, the power-on up-shift is continued while lowering the engaging capacity of the lock-up clutch. |
