PROBLEM TO BE SOLVED: To provide an engine torque correction device for an internal combustion engine that can determine appropriate engine torque by correcting engine torque even when change in ignition timing causes rotational frequency of a turbo supercharger to be changed and thus intake air amount is changed.SOLUTION: An ECU 100 includes: an engine torque fluctuation amount calculation section 101 for calculating engine torque fluctuation amount corresponding to a difference between before and after change of ignition timing, when a variation of a throttle opening is a predetermined value or lower and the ignition timing has been changed; and a correction section 102 for correcting engine torque by using the engine torque fluctuation amount as correction amount. The engine torque fluctuation amount calculation section 101 calculates the engine torque fluctuation amount on the basis of a variation of intake pipe pressure or a variation of intake air amount that is determined from a difference between before and after the change of the ignition timing. The engine torque fluctuation amount calculation section 101 corrects the engine torque fluctuation amount in accordance with engine speed.SELECTED DRAWING: Figure 1 |
