    摘要： An engine ECU executes a program including the steps of: calculating (S200) an absolute value ΔS(I) of the deviation of the vibration waveform detected by a knock sensor and a knock waveform model from each other at each crank angle; when ΔS(I) greater than threshold value ΔS(0) is present (YES in S202) and the number of ΔS(I) greater than threshold value ΔS(0) is equal to or smaller than Q(1) (YES in S300), correcting the vibration waveform (S304); calculating (S308) a correlation coefficient K which is a value related to the deviation of the corrected vibration waveform and the knock waveform model from each other; and when the number of ΔS(I) greater than threshold value ΔS(0) is greater than predetermined number Q(1) (NO in S300), calculating the correlation coefficient K without correcting the vibration waveform. Based on the correlation coefficient K, whether knocking is present or absent is determined.

    摘要： An engine ECU 200 includes a bandpass filter (1) (410), a bandpass filter (2) (420), and a bandpass filter (3) (430). The bandpass filter (1) (410) extracts only vibrations at a first frequency band A from the vibrations detected by a knock sensor. The bandpass filter (2) (420) extracts only vibrations at a second frequency band B from the vibrations detected by the knock sensor. The bandpass filter (3) (430) extracts only vibrations at a third frequency band C from the vibrations detected by the knock sensor. The first to third frequency bands A-C are identical in bandwidth. The engine ECU (200) calculates a peak value in magnitude of vibrations in a synthesized waveform of these frequency bands, and determines whether knocking occurred or not based on the peak value.

    摘要： An object of this invention is to provide a control apparatus for an internal combustion engine that can suppress the emission of unburned HC accompanying start-up of an internal combustion engine. The control apparatus for an internal combustion engine of this invention includes: fuel supply control means that, when a multi-cylinder internal combustion engine is started, initially supplies fuel to only some cylinders, and delays the start of fuel supply to delayed cylinders that are cylinders other than the aforementioned cylinders; engine discharge gas HC amount predicting means that, based on predetermined parameters including at least a representative temperature of the internal combustion engine, calculates a relationship between a delayed cylinder starting engine speed that is a engine speed at a timing at which a cycle starts in which a delayed cylinder initially carries out combustion and a predicted value of an engine discharge gas HC amount; and target engine speed calculating means that, based on the relationship, calculates a target engine speed that is a target value of the delayed cylinder starting engine speed; wherein the fuel supply control means determines a timing at which to start to supply fuel to the delayed cylinders so that the delayed cylinder starting engine speed is in a vicinity of the target engine speed.

    摘要： In a torque control device for an internal combustion engine (1), a driving-system torque calculation unit calculates a driving-system torque operating on a driving system (5), based on a requested torque at a time of acceleration. A torque control unit (20) executes torque control so that a gradient of the driving-system torque becomes equal to or smaller than a predetermined value, based on the driving-system torque calculated by the driving-system torque calculation unit. Thereby, since an amount of twist of the driving system can be maintained equal to or smaller than a predetermined value, repetitive shock can be suppressed, and acceleration shock can be effectively suppressed, too. Response deterioration and fuel consumption deterioration at the time of acceleration can be prevented.

    摘要： An engine controller calculates a pulsation correction value based on actuation states of an air bypass valve (ABV) and a wastegate valve (WGV) that change the shape of intake and exhaust flow passages of an exhaust turbocharger. The pulsation correction value is used to compensate for an output error of an airflow meter caused by intake pulsation. The engine controller also calculates a fuel injection amount of an injector, based on an output of the airflow meter that has been corrected based on the pulsation correction value.
