PCT No. PCT/JP90/00063 Sec. 371 Date Sep. 18, 1990 Sec. 102(e) Date Sep. 18, 1990 PCT Filed Jan. 19, 1990 PCT Pub. No. WO90/08889 PCT Pub. Date Sep. 8, 1990.In an output control apparatus for an internal combustion engine according to this invention, a target torque of a driving shaft of an automobile is determined in accordance with the pedaling stroke of an accelerator pedal, and a deviation between the target torque and an actual torque of the driving shaft is obtained. On the assumption that the whole system of the automobile, including the internal combustion engine, is in a steady-state operation mode, on the other hand, a steady-state output torque of the internal combustion engine, required for applying the target torque to the driving shaft, is obtained. In the output control apparatus, moreover, a steady-state suction air amount of the internal combustion engine is obtained such that the steady-state output torque is obtained in the internal combustion engine, and this steady-state suction air amount is corrected in accordance with a feedback amount based on the aforesaid deviation, so that a target suction air amount of the internal combustion engine is determined, and the opening of a throttle valve is controlled so that the target suction air amount can be obtained.
