| 20090319109 | POWER OUTPUT APPARATUS, CONTROL METHOD THEREOF, AND VEHICLE - A power output apparatus includes a control unit that controls an internal combustion engine, a generator, and an electric motor such that a required driving force is output to a drive shaft. The control unit learns an idle control amount, which is a control amount obtained during an idle operation of the internal combustion engine, in accordance with establishment of a predetermined learning condition when a rotation variation amount of the drive shaft is within a predetermined range including a value of zero, and does not learn the idle control amount when the rotation variation amount of the drive shaft is not within the predetermined range. | 12-24-2009 |
| 20090319158 | POWER OUTPUT APPARATUS, CONTROL METHOD THEREOF, AND VEHICLE - A power output apparatus for outputting power to a drive shaft includes a control unit that controls an internal combustion engine to perform an idle operation at a predetermined rotation speed, executes idle control amount learning, in which an idle control amount serving as a control amount obtained during the control is learned in accordance with establishment of a predetermined learning condition, within a range in which a rotation speed of the drive shaft is lower than a first speed, when the idle control amount learning is incomplete, and executes again the idle control amount learning within a range in which the rotation speed of the drive shaft is lower than a second speed, which is lower than the first speed, when the idle control amount learning is complete. | 12-24-2009 |
| 20100204864 | HYBRID VEHICLE AND CONTROL METHOD THEREOF - When the catalyst warm-up is not completed and the driving power Pdrv is larger than the battery output allowable power (k·Wout), the power demand Pe* to be output from the engine | 08-12-2010 |

| 20080275626 | Vehicle and Control Method of Vehicle - In a vehicle equipped with both an engine and a motor as the driving power source, in the event of incompletion of learning a control demand for regulation of an idling rotation speed of the engine, intermittent operation prohibition control of the invention permits intermittent operation of the engine under the setting of a gearshift lever to a parking position. The intermittent operation prohibition control of the invention prohibits the intermittent operation of the engine, on the other hand, under the setting of the gearshift lever to a drive position. This arrangement avoids the continuous operation of the engine against the driver's expectation, while prohibiting the intermittent operation of the engine to ensure the opportunity of learning the control demand for regulation of the idling rotation speed of the engine. | 11-06-2008 |
| 20090276144 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - A fuel supply system includes a first non-return valve for a low-pressure delivery connection pipe and a second non-return valve for a pump supply pipe. The former non-return pipe does not allow fuel to flow from the low-pressure delivery pipe to the low-pressure supply pipe. The second non-return valve does not allow fuel to flow from pump supply pipe to the low-pressure supply pipe. Upon determining that air purging is necessary, an engine ECU operates a feed pump for approximately one second and then opens, for dummy injection, an in-cylinder injector and an intake manifold injector. | 11-05-2009 |
| 20100106355 | CONTROL UNIT AND CONTROL METHOD FOR VARIABLE VALVE TIMING MECHANISM, PROGRAM FOR IMPLEMENTING THE CONTROL METHOD, AND RECORDING MEDIUM ON WHICH THE PROGRAM IS RECORDED - An ECU executes a program based on which, when a fuel-supply cutoff control is executed or when a hybrid vehicle travels in a second mode in which the engine is stopped and the hybrid vehicle travels using only the drive power generated by a second MG an intake VVT mechanism is controlled so that a valve phase is brought to the mechanically determined most retarded phase. The phase, which is detected by a cam position sensor, is learned as the most retarded phase. | 04-29-2010 |
