摘要： An atmospheric pressure estimating apparatus which estimates an atmospheric pressure applied to a calculation of control parameters of an internal combustion engine, is provided. An estimated intake air control valve passing air flow rate is calculated based on the estimated atmospheric pressure, the detected intake pressure, and the detected intake air control valve opening. The estimated atmospheric pressure is updated so that the estimated intake air control valve passing air flow rate coincides with the detected intake air control valve passing air flow rate. The estimated intake air control valve passing air flow rate is calculated using the updated estimated atmospheric pressure. The update of the estimated atmospheric pressure and the calculation of the estimated control valve passing air flow rate are sequentially performed. Consequently, the estimated control valve passing air flow rate follows the intake air flow rate, and the estimated atmospheric pressure follows the atmospheric pressure.

摘要： A control system for an internal combustion engine, which controls an output torque of the internal combustion engine for driving a vehicle, is provided. An engine rotational speed is detected, and a change amount of the detected engine rotational speed is calculated. The output torque control amount of the engine is corrected so that the rotational speed change amount coincides with the center value of the local minimum value and the local maximum value of the rotational speed change amount. Specifically, a torque correction amount is calculated according to a torque value which is equal to half of a difference between peak vibration torque values corresponding to the local minimum value and the local maximum value of the rotational speed change amount, and an output torque control amount is corrected with the torque correction amount.
