摘要： An engine control apparatus includes a target air volume calculator which calculates a target air volume required by an engine, and an actual air volume calculator which calculates an actual air volume inhaled into a cylinder of the engine. The apparatus further includes an estimator which calculates the estimated value of subsequent actual air volume on the basis of a time lag from a time when the target air volume is calculated to a time when the actual air volume reaches the target air volume. The apparatus can accurately estimate an intake air volume inhaled into the cylinder to improve the controllability of the engine.

摘要： An engine controlling apparatus includes a setting unit that sets a demand torque to an engine, a detection unit that detects a fluctuation of an external load, and a correction unit that corrects the demand torque. The apparatus includes a target torque calculation unit that calculates a target torque based on the demand torque, a control unit that controls an amount of air to be introduced into the engine so that an output torque may come close to the target torque, and an ignition timing detection unit that detects an ignition timing of the engine.The correction unit adds a torque increment for coping with a fluctuation of the external load to the demand torque to determine an increment correction demand torque and increases or decreases the increment correction demand torque in response to a displacement amount of the ignition timing from a predetermined reference value.
