A control device for an internal combustion engine (E) and a continuous variable transmission (35) according to the present invention is disposed in a power transmission method (P) between the internal combustion engine (E) mounted on a vehicle and driving wheels (32) and of which transmission ratio can be continuously changed at a predetermined transmission speed Vm so as to maintain the transmission ratio i suitable for engine speed w35) sets the transmission speed Vm according to a deviation D35) at the transmission speed Vm. On the other hand, it controls the power of the internal combustion engine (E) by means of transmission auxiliary torque D35 at suitable transmission speed Vm. This results in reduction of the slip and shock caused on transmission operation of the continuous variable transmission (35).
