PURPOSE: To detect the effective and actual opening of a throttle valve as accurately as possible, by determining a deviation between the estimated opening, which is set by a deviation between a lambda value expected for the predetermined estimated operational status and a lambda value measured in the actual operational status, and an actual opening. CONSTITUTION: An intake system is provided with a throttle valve 13 and a fuel injection device 14. An exhaust system is disposed with a lambda sensor 15. The opening of the throttle valve can be set by an accelerator pedal 16 and is measured by an opening sensor 17. Respective values of an openingα, a lambda value 2, and the rotational speed (n) of an internal combustion engine 10 are inputted into a controller 20 provided with a ROM 18 and EEPROM 19. The controller 20 conducts processing stored in a ROM 19 and the deviated valueΔa computed for the opening is stored in a EEPROM 20. The output signal of the controller 20 computed using the stored deviated value is fed into the fuel injection device 14.
