20090283075 | INTERNAL COMBUSTION ENGINE APPARATUS, VEHICLE INCLUDING INTERNAL COMBUSTION ENGINE APPARATUS, AND CONTROL METHOD OF INTERNAL COMBUSTION ENGINE APPARATUS - In performing purge control, an engine ECU | 11-19-2009 |
20090292449 | POWER OUTPUT APPARATUS, VEHICLE EQUIPPED WITH THE SAME, AND METHOD OF CONTROLLING POWER OUTPUT APPARATUS - In a power output apparatus, when the fuel vapor concentration is high and the target purge rate is high, an operating point on a purge priority operating line is selected as a target operating point of an engine. As a result, the intake manifold negative pressure greater than that when an operating point on an optimum fuel efficiency operating line is selected, so that the flow rate of purge gas released from a canister is increased. When the fuel vapor concentration does not fall within a high-concentration range, the necessity to immediately purge fuel vapor trapped in the canister into the intake pipe is low, and thus an operating point on the optimum fuel efficiency operating line is selected to keep the engine operating at high fuel efficiency. | 11-26-2009 |
20120131992 | CATALYST DETERIORATION DIAGNOSTIC DEVICE AND DIAGNOSTIC METHOD - A device for diagnosing deterioration of a catalyst by a decrease in oxygen storage capacity, in which the oxygen storage capacity by which the catalyst deterioration is diagnosed to be present when exhaust gas recirculation is not implemented is higher than the oxygen storage capacity by which the catalyst deterioration is diagnosed to be present when the exhaust gas recirculation is implemented. | 05-31-2012 |
20120310458 | VEHICLE, METHOD AND DEVICE FOR CONTROLLING ENGINE - A vehicle provided with a motor generator as a driving source includes a battery to supply electric power to the motor generator, an engine, and an ECU to control the vehicle in one of a CS mode and a CD mode in which opportunity for operation of the engine is limited compared to in the CS mode. The ECU controls the engine in accordance with a condition different from a condition used to control the engine in the CS mode, if the engine is started at least due to decrease in a state of charge of the battery while the vehicle is controlled in the CD mode. | 12-06-2012 |
20130274977 | HYBRID VEHICLE AND CONTROL METHOD FOR HYBRID VEHICLE - A hybrid vehicle intermittently operates and stops an engine, travels through control over torque generated by the engine and torque generated by a second motor generator, causes a fuel vapor gas purge system to carry out purging of fuel vapor gas when a predetermined condition, including a condition that a coolant temperature is higher than or equal to a permissible temperature, is satisfied, and sets the permissible temperature to a value lower when a specific driving operation state that includes a state where the number of times of accelerator operation per unit time is higher than or equal to a threshold has been detected than when the specific driving operation state has not been detected. When the specific driving operation state has been detected, the hybrid vehicle increases the updating rate of a concentration learned value of fuel vapor gas, and decreases the rate of increase in target purge rate. | 10-17-2013 |
20130297137 | VEHICLE AND METHOD OF CONTROLLING VEHICLE - A vehicle includes an engine, a power storage device, a motor generator using electric power from the power storage device for generating driving force, and an ECU. The vehicle is capable of running with the operation mode selectively switched between the CS mode in which the vehicle runs utilizing the driving force from the engine and the motor generator, and the CD mode in which the vehicle runs preferentially utilizing the driving force from the motor generator in the state where the engine is stopped. When the OBD is performed for detecting a malfunction in the engine in the state where the CD mode is selected, the ECU keeps the operation mode being temporarily switched from the CD mode to the CS mode until the OBD is completed. | 11-07-2013 |
20130304291 | VEHICLE, METHOD AND DEVICE FOR CONTROLLING VEHICLE - A vehicle provided with a motor generator as a driving source includes an engine and a catalyst for purifying gas exhausted from the engine. The engine is controlled in one control mode of a CS mode and a CD mode in which opportunity for operation of the engine is limited compared to in the CS mode. In the CS mode, the temperature of the catalyst is increased to be equal to or higher than a prescribed activating temperature. The temperature of the catalyst is increased to be higher than the activating temperature before the control mode is changed from the CS mode to the CD mode. | 11-14-2013 |
20140020461 | CATALYST DETERIORATION DIAGNOSTIC DEVICE AND DIAGNOSTIC METHOD - A device for diagnosing deterioration of a catalyst by a decrease in oxygen storage capacity, in which the oxygen storage capacity by which the catalyst deterioration is diagnosed to be present when exhaust gas recirculation is not implemented is higher than the oxygen storage capacity by which the catalyst deterioration is diagnosed to be present when the exhaust gas recirculation is implemented. | 01-23-2014 |
20140296025 | CONTROL SYSTEM FOR VEHICLE - A control system for a vehicle includes: an engine; a first electric motor configured to output a starting torque for starting the engine; a second electric motor configured to output a starting torque for starting the engine and a running torque; an electrical storage device configured to supply electric power to the first electric motor and the second electric motor; and a controller configured to start the engine with the use of both the first electric motor and the second electric motor at the time of starting the engine when the sum of a required driving torque that is required for the vehicle and a required starting torque that is required to start the engine is larger than a maximum output torque of the second electric motor, which is outputtable at the electric power from the electrical storage device. | 10-02-2014 |
20150032326 | FAILURE DIAGNOSIS APPARATUS OF HYBRID VEHICLE - A failure diagnosis apparatus comprises a controller that is configured to execute a failure diagnosis process of the internal combustion engine based on a predetermined diagnosis requirement. The diagnosis requirement in a case where engine-operation-electric-power supply is executed is made different from the diagnosis requirement in a case where engine-normal-operation is executed such that a failure of the internal combustion engine in the case where the engine-operation-electric-power supply is executed is less likely to be detected or the failure of the internal combustion engine is less likely to be recognized by a driver than in the case where the engine-normal operation is executed. | 01-29-2015 |
