摘要： Upon incompletion of abnormality detection of an air-fuel ratio sensor provided in an exhaust pipe of an engine during operation of the engine (steps S310 and S320), when the state of charge SOC of a battery is lower than a preset reference charge level Sref or when the accelerator opening Acc is not less than a preset reference opening Aref (steps S330 and S340), the abnormality detection is not performed (step S350). When the state of charge SOC of the battery is not lower than the preset reference charge level Sref and when the accelerator opening Acc is less than the preset reference opening Aref (steps S330 and S340), the abnormality detection is performed to identify abnormality or normality of the air-fuel ratio sensor based on an air fuel ratio AF output from the air-fuel ratio sensor (steps S360 to S420). The drive control cuts off a fuel supply to the engine, controls a motor to enable motoring of the engine, and ensures output of a torque demand to a driveshaft, while the abnormality detection is performed.

摘要： The engine misfire detection apparatus of the invention successively determines whether a rotational fluctuation difference Nxd360 as a difference between a rotational fluctuation Nxd at a certain crank angle CA of an engine and a rotational fluctuation Nxd at a 360 degree-prior crank angle CA exceeds a predetermined reference value A1 (step S150) and whether a rotational fluctuation difference Nxd720 as a difference between the rotational fluctuation Nxd at the certain crank angle CA and a rotational fluctuation Nxd at a 720 degree-prior crank angle CA exceeds a predetermined reference value B1 (step S160). The engine misfire detection apparatus detects a misfire of the engine upon satisfaction of all conditions regarding rotational fluctuation difference proportions Nja2, Nja3, and Nja4 on the basis of the rotational fluctuation difference Nxd360 (step S200) and all conditions regarding rotational fluctuation difference proportions Njb2, Njb3, and Njb4 on the basis of the rotational fluctuation difference Nxd720 (step S210), when both the rotational fluctuation differences Nxd360 and Nxd720 exceed the respective reference values A1 and B1 (steps S150 and S160). This arrangement ensures adequate and accurate detection of an engine misfire during warm-up of a catalyst included in an exhaust emission control unit with a significant delay of the ignition timing in the engine.

摘要： The engine misfire detection process according to one aspect of the invention first makes tentative detection on the occurrence or the non-occurrence of an engine misfire in execution of both vibration control and rotation speed control. In response to the tentative detection of an engine misfire, the engine misfire detection process subsequently makes final detection on the occurrence or the non-occurrence of an engine misfire. In the event of no final detection of an engine misfire, the engine misfire detection process makes tentative detection and final detection on the occurrence or the non-occurrence of an engine misfire in prohibition of the vibration control. In the event of still no final detection of an engine misfire, the engine misfire detection process makes tentative detection and final detection on the occurrence or the non-occurrence of an engine misfire in further prohibition of the rotation speed control. Even in the event of no final detection of an engine misfire in execution of both the vibration control and the rotation speed control, the procedure of the invention makes final detection on the occurrence or the non-occurrence of an engine misfire in prohibition of execution of the vibration control and further the rotation speed control. This arrangement desirably increases the detection frequency of engine misfires.

摘要： Upon no detection of the closing abnormality where the EGR valve does not become in the totally closed state (when the flag Fa is value ‘0’), the engine is controlled using the target fuel injection amount obtained from the correction of the basic fuel injection amount toward the increase direction, in the case that the engine is operated together with the recirculation of the exhaust in the preset high-load operation range (when the flag Fi is ‘1’). Upon detection of the closing abnormality (when the flag Fa is value ‘1’), the engine is controlled using the target fuel injection amount obtained from the correction of the basic fuel injection amount toward the increase direction, in the case that the engine is operated together with the recirculation of the exhaust in the whole range that the engine is operable together with the recirculation of the exhaust.

摘要： Engine misfire is detected by using threshold values that vary depending on whether damping control is executed. First threshold values are adopted at the setting of a gearshift position to a drive position or a park position where damping control is performed to reduce the vibration of an engine. Second threshold values are adopted at the setting of the gearshift position to a neutral position where the damping control is not performed, the second threshold values being greater than the first threshold values. Engine misfire detection is carried out by processing using the first and second threshold values.

摘要： In the case of non-execution of catalyst warm-up acceleration control, the engine misfire detection procedure compares a 30-degree rotation time computed as a time required for a 30-degree rotation of an engine crankshaft with preset reference values Tref1 and Tref2 and distinctly detects the occurrence of intermittent engine misfires and the occurrence of either a single engine misfire or consecutive engine misfires (steps S120 to S150). In the case of execution of the catalyst warm-up acceleration control, the engine misfire detection procedure compares the 30-degree rotation time computed as the time required for a 30-degree rotation of the engine crankshaft with preset reference values Tref3 and Tref4 and distinctly detects the occurrence of the consecutive engine misfires and the occurrence of either the single engine misfire or the intermittent engine misfires (steps S160 to S190). This arrangement ensures accurate detection and identification of engine misfires, regardless of execution or non-execution of the catalyst warm-up acceleration control.

摘要： An ECU executes a program including steps of estimating an oil temperature based on a water temperature sensed by a water temperature sensor, setting NE(1) to a lower limit value of an engine revolution speed NE when the oil temperature is equal to or higher than a threshold THO(0), setting NE(2) (NE(2)
