PROBLEM TO BE SOLVED: To quickly perform a transmission control, when a switch control of a shift stage is continued when an additional target shift stage is set before the switch control of the shift stage is completed. SOLUTION: A control device for an automatic transmission comprises: a first friction element, which is released at a first shift stage, is engaged at a second shift stage after first transmission, and is released at a third shift stage after second transmission; a second friction element, which is engaged at the first shift stage, is released at the second shift stage, and is released at the third shift stage; and a third friction element, which is released at the first shift stage, is released at the second shift stage, and is engaged at the third shift stage. When a target shift stage is changed from the second shift stage to the third shift stage after detection of the start of inertia phase of the first transmission, the second transmission is started while performing the first transmission, a hydraulic pressure command value in the first transmission is compared with a hydraulic command value in the second transmission, and a smaller one is selected as a hydraulic command value with respect to the first friction element.
