| 20100036589 | POWER OUTPUT APPARATUS, INTERNAL COMBUSTION ENGINE SYSTEM, AND CONTROL METHODS THEREOF - On the occasion of a cutoff of fuel supply to an engine in an accelerator-off state, the invention expands a throttle opening over a specific throttle opening set in the state of idling of the engine at the reference rotation speed. On resumption of fuel injection to the engine, the invention reduces the throttle opening to the specific throttle opening set in the state of idling of the engine at the reference rotation speed. Under no control of lowering the rotation speed of the engine by a motor or under the condition of low vehicle speed with control of lowering the rotation speed of the engine by the motor, the invention resumes fuel injection to the engine resumed with setting of a smaller correction amount to a fuel increase correction amount. | 02-11-2010 |
| 20100049389 | HYBRID VEHICLE AND MOTOR DRIVE CONTINUABLE RANGE DISPLAYING METHOD - When the EV switch is on, a first motor drive continuable time is calculated based on the state of charge of the battery and the unit time driving power, and a second motor drive continuable time is calculated as a time until reaching a lower limit temperature θref allowing the catalyst of the purifying device to function, and whichever is shorter, is visibly displayed to a driver. This allows the range capable of continuing motor drive to be displayed more appropriately to the driver than a method of displaying the time simply by the state of charge of the battery, and can reduce an uncomfortable feeling of the driver due to an unexpected start of the engine. | 02-25-2010 |
| 20100082188 | HYBRID VEHICLE AND CONTROL METHOD OF HYBRID VEHICLE - On a restart of an engine accompanied with a change from a motor drive of a hybrid vehicle to a hybrid drive, when a temperature of a catalyst in a catalytic converter located in an exhaust pipe of the engine decreases below a preset reference temperature to be out of a specific temperature range of ensuring sufficient catalyst performance, a power restriction value is set according to the catalyst temperature and an EV drive time representing a time duration of the motor drive. An engine power demand to be output from the engine is set under output restriction with this power restriction value. The engine and two motors are then controlled with the set engine power demand. This arrangement effectively prevents poor emission and ensures good driving performance of the vehicle even in the event of a temperature decrease of the catalyst by the motor drive of the vehicle. | 04-01-2010 |
| 20100162707 | INTERNAL COMBUSTION ENGINE APPARATUS, CONTROL METHOD THEREOF, AND HYBRID VEHICLE - An internal combustion engine apparatus provided with an internal combustion engine in which ignition timing can be adjusted and which has attached thereto an exhaust gas recirculation device that recirculates exhaust gas to an intake side, a control method for the internal combustion engine apparatus, and a hybrid vehicle are provided. When it is not a recirculation ratio variation time, a target ignition timing is set by correcting a base ignition timing that has been established as a base value of an ignition timing of the internal combustion engine by a first correction amount, and when it is the recirculation ratio variation time, the target ignition timing is set by correcting the base ignition timing by a second correction amount that delays an ignition timing more than a provisional correction amount obtained by correcting the first correction amount, and the internal combustion engine is controlled so that the internal combustion engine is operated due to the ignition at the target ignition timing that has been set. | 07-01-2010 |
| 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 |
