Abstract
In a control device which uses a specific physical quantity as a control variable of an internal combustion engine, and controls the internal combustion engine by manipulation of one or a plurality of actuators, switching of setting of a manipulation variable based on a required value of a physical quantity and setting of the manipulation variables by direct instruction to individual actuators is performed without generating discontinuity in a realized value of the physical quantity. When a manipulation variable instruction value directly designating a manipulation variable of an actuator is present, the manipulation variable instruction value is converted into a value of a physical quantity which is realized in the internal combustion engine by the operation quantity instruction value. When a deviation between a physical quantity conversion value converted from the manipulation variable instruction value and the physical quantity required value is within a predetermined range, switch of information for use in setting of the manipulation variable of each of the actuators is permitted.
