摘要： Disclosed is an internal combustion engine control device. The control device is provided with an engine output shaft, a constant mesh starter, fuel injection valves, and a reduction correcting section. After automatic stop conditions are met, engine operation is restarted when restart conditions are met. At this time, the control device uses the aforementioned starter to rotationally drive the aforementioned engine output shaft, and restarts fuel injection by the aforementioned fuel injection valves when the aforementioned engine is in a transient state in which speed has been reduced to a speed at which the rotation of the aforementioned engine output shaft cannot restore the engine to autonomous operation but in which rotation has not completely stopped. When the aforementioned restart conditions are met, if the internal combustion engine is in the aforementioned transient state, the reduction correcting section correctively reduces the start-time fuel injection amount during engine operation restart compared with when rotation of the aforementioned output shaft is completely stopped.

摘要： Provided is an abnormality determination device for a rotation sensor for detecting the rotation of a crankshaft. The rotation sensor comprises a sub sensor and a main sensor each of which outputs a pulsed signal every time the rotation body rotates by a predetermined angle. The rotation sensor is configured to, when the condition that the output signal of the sub sensor has a predetermined value and the output signal of the main sensor has changed is met, output a pulse signal in a different output form according to the direction of change of the output signal of the main sensor when the condition is met. The abnormality determination device is provided with an electronic controller which determines that the rotation sensor is abnormal on the basis of the fact that the output form of one pulse signal and the output form of the other pulse signal of two pulse signals outputted continuously from the rotation sensor within a determination period in which the crankshaft rotates in only a predetermined direction are different.

摘要： An engine ECU executes a program including the step of calculating a correlation coefficient K by dividing the sum SDS(I) of respective absolute values DS(I), which are each a difference between a magnitude in an engine vibration waveform and a magnitude in a knock waveform model for every crank angle, by an area S corresponding to magnitudes equal to or larger than a positive reference value in the knock waveform model (S110), and the step of determining whether or not knocking has occurred based on the correlation coefficient (S116, S120).

摘要： An engine ECU executes a program including the steps of: detecting a magnitude of vibration of an engine (S 102); detecting a vibration waveform of the engine based on the magnitude (S 104); calculating a correlation coefficient K, in the case where the engine speed NE is smaller than a threshold value NE (1), using the sum of values each determined by subtracting a positive reference value from a magnitude of a knock waveform model, as an area S of the knock waveform model and, calculating the correlation coefficient K, in the case where the engine speed NE is not smaller than the threshold value NE (1), using the area S of the whole knock waveform model (Sl 14); and determining whether or not knocking has occurred using the correlation coefficient K (S 120, S 124). The correlation coefficient K is calculated by dividing by the area S the sum of differences that are each the difference between the magnitude on the vibration waveform and the magnitude on the knock waveform model.
