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： A controller of an internal combustion engine is provided. The engine has a crankshaft that receives rotational force from a starter when the engine is started. The controller executes stop control of the engine based on an automatic stop request, and executes restart control of the engine based on a restart request. The controller includes a predicting section and a setting section. The predicting section predicts, during the execution of the stop control, a starting rotational force required for rotating the crankshaft to restart the engine. The setting section sets a determination value used for determining whether the starter needs to be activated in the restart control. The greater the starting rotational force predicted by the predicting section, the higher the determination value set by the setting section becomes. The controller further includes a determining section. When an engine speed at the time when the restart request is made is lower than the determination value, the determining section determines that the starter needs to be activated in the restart control.

摘要： Disclosed is an abnormality determination device for a rotation sensor for detecting the rotation of a crankshaft. The rotation sensor comprises a first sensor unit and a second sensor unit which output signals phase-shifted from each other, and outputs a pulse signal. When the direction of change of the output signal of the second sensor unit is a first direction, the pulse signal having a first duration is outputted. When the direction of change of the output signal of the second sensor unit is a second direction, the pulse signal having a second duration is outputted. The abnormality determination device comprises a calculation unit which calculates the time interval between the output start times of the pulse signal, and a determination unit which determines that the rotation sensor is abnormal when the difference between two time intervals calculated continuously by the calculation unit is larger than a threshold value.

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.

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.
