Disclosed is a control device for a vehicle drive device whereby an improvement in vehicle response to accelerator operation by the driver can be achieved, in a vehicle equipped with an internal combustion engine, a supercharger and an automatic transmission. Gear ratio selection control means (80), when the engine (12) is operating in NA condition, if the engine (12) comes to operate in a supercharged condition on change of ratio of the automatic transmission (16) to a first gear ratio (³1at) in accordance with the gear-change map, performs gear ratio selection control so as to alter the method of selection of the gear ratio (³at) of the automatic transmission (16) in accordance with an increased rate (SPacc) of opening (Acc) of the accelerator. Specifically, in this gear ratio selection control, at the side where the increased rate (SPacc) of opening (Acc) of the accelerator is least, the automatic transmission (16) changes to a first gear ratio (³1at), but, at the side where the increased rate (SPacc) of degree of opening (Acc) of the accelerator is greatest, the engine (12) is still maintained in the aforementioned NA condition and the automatic transmission (16) is changed to a second gear ratio (³2at), which is larger than the first gear ratio (³1at). |
