| 20090065275 | Engine misfire detection apparatus, hybrid vehicle equipped with the same, and engine misfire detection method - At the setting of a gearshift position to a D position or a P position (step S | 03-12-2009 |
| 20100071448 | Engine Misfire Detection Apparatus, Hybrid Vehicle Equipped With the Same, and Engine Misfire Detection Method - At a Lo gear position of a transmission, the engine misfire detection process of the invention sets a first threshold value A | 03-25-2010 |
| 20100114460 | Engine Misfire Detection Apparatus for Internal Combustion Engine and Engine Misfire Detection Method - 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. | 05-06-2010 |

| 20080228373 | Control device and control method of internal combustion engine - 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( | 09-18-2008 |
| 20080277176 | Power output apparatus, vehicle equipped with power output apparatus, and control method of power output apparatus - 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 S | 11-13-2008 |
| 20100251996 | POWER OUTPUT APPARATUS, HYBRID VEHICLE PROVIDED WITH SAME, AND CONTROL METHOD OF POWER OUTPUT APPARATUS - A power output apparatus that outputs power to a drive shaft includes an internal combustion engine, an exhaust gas control apparatus, an electric motor, a power storage device, a required torque setting portion, a required power setting portion, an allowable discharge electric power setting portion, and a control portion that controls the internal combustion engine and the electric motor such that the internal combustion engine is operated at a preset catalyst warm-up operating point and torque that is based on a set required torque is output to the drive shaft, when a set required power is equal to or less than a set allowable discharge electric power when catalyst warm-up to promote activation of a catalyst needs to be executed. | 10-07-2010 |
