20090063024 | MISFIRE DETECTION APPARATUS FOR INTERNAL COMBUSTION ENGINE - In an internal combustion engine including a flywheel damper, an operation range in which misfire detection is affected by the flywheel damper is set in advance. Whether or not an operation state of the internal combustion engine is within an operation range affected by the flywheel damper is determined. When the operation state is within the operation range affected by the flywheel damper, for example a cylinder specifying process specifying a misfiring cylinder is stopped. By such processing, erroneous detection attributed to irregular rotation fluctuation behavior caused by the flywheel damper can be avoided, and misfire detection performance can be improved. | 03-05-2009 |
20110100344 | VEHICLE AND VEHICLE CONTROL METHOD - An engine ECU calculates a rotational variation based on a required rotation time when a complete misfire occurs in a cylinder, a required rotation time when complete combustion occurs in the cylinder, and a required rotation time during the current combustion stroke, and integrates the calculated rotational variation. If it is determined that the number of times the rotational variation has been integrated has reached a predetermined number, the engine ECU calculates an amount of learning value deviation from the integrated rotational variation. If the amount of learning value deviation is equal to or greater than a certain amount, the engine ECU corrects a learning value of a sub-feedback control with respect to the air-fuel ratio. | 05-05-2011 |

20090015205 | HYBRID CONTROL DEVICE - In a hybrid control device performing cooling control of a secondary battery of a hybrid vehicle, the hybrid control device limiting the amount of charge/discharge of the secondary battery based on an air volume flow of a cooling fan cooling the secondary battery, an operation control mode of the secondary battery cooling fan is changed from an ordinary control mode to a power mode in which an air volume flow of the cooling fan is larger than in the ordinary control mode, whereby a limiting value of the amount of charge/discharge of the secondary battery is varied to expand the usable range of the secondary battery. Accordingly, when improvement of drive power performance is desired by an operator more than low noise within the vehicle, the amount of charge/discharge of the secondary battery is not limited by the cooling fan, and larger drive power performance is thus achieved. | 01-15-2009 |
20110318627 | TEMPERATURE ADJUSTING STRUCTURE FOR ELECTRIC STORAGE MODULE - A temperature adjusting structure adjusting the temperature of an electric storage module mounted on a vehicle has an intake path which takes in air in the vehicle interior from an intake port and guides the air to the electric storage module located below a horizontal plane on which the intake port is located. A bottom face of the intake path has an inclined face extending upward from a lower end portion of the intake port and facing the intake port. | 12-29-2011 |
