Abstract
An engine output control apparatus for an internal combustion engine includes a drive force transferring section interconnected with a crankshaft of the engine. The output of the engine is controlled at a desired value by an output control section. A transferred torque through the drive force transferring section is estimated by a torque estimating section. A torque suppressing section lowers the output of the engine so as to keep the estimated torque within a predetermined range by sending a signal to the output control section. A shift detecting section outputs a signal to a time delaying section when it detects a shifting from an output-control required shift position to a normal shift position. The time delay section outputs the estimated torque value to the torque suppressing section upon delaying for a predetermined delay time corresponding to a shifting time when the time delay section is operated by the shift detecting section. Therefore, the suppression of the engine output is executed by the torque suppressing section after the shifting.
