Provided is an internal combustion engine control device which can compensate a weak point in the so-called torque-demand control so as to accurately reflect a request for the internal combustion engine performance in a control amount of each actuator. Requested values of a torque, efficiency, and an air-fuel ratio and engine information are inputted to an engine inverse model (30) so as to calculate actuator request values for realizing the requested values by using the engine inverse model (30). Moreover, an actuator direct request value is also acquired for each of the actuators (2, 4, 6). Control of the actuators (2, 4, 6) can be switched between control based on the actuator request values and control based on the actuator direct request values.
