An electric motor control method is an control method which is capable of selecting a first mode or a second mode as a control mode for controlling an operation of the electric motor according to an operating state of the electric motor. The method, when the second mode is selected as the control mode, stops a part of processing in the first mode, and continuously executes other processing including integral calculation except for the part of processing in the first mode. Also, the method, when the control mode is switched from the second mode to the first mode, starts the part of processing by using at least one control value obtained by continuing the other processing.
