A method of generating action control data includes an actuator as a control object, a detector for detecting an actual measured data of an action signal in the actuator, and a data map including control data which can perform a preferable condition of control by activating the actuator. The method of generating action control data for activating the actuator in accordance with a driving condition appropriate at a time of controlling on the basis of an appropriate control data selected from the data map includes the steps of calculating a deviation between the appropriate control data and an actual measured data, modifying the appropriate control data on the basis of calculated deviation, and generating the modified appropriate control data as the action control data.
