Abstract: PROBLEM TO BE SOLVED: To more properly cope with the lowering of power outputted from an internal combustion engine.
SOLUTION: When an engine is operated and an engine demand power Pe* becomes lower than an engine stop determination value Pstp, the operation of the engine is stopped (S330 to S370). When the operation of the engine is stopped and the engine demand power Pe* becomes higher than an engine start determination value Pstrt, the engine is started (S250 to S310). Since the engine stop determination value Pstp and the engine start determination value Pstrt are set to smaller values than those at a normal time when using regular fuel, the engine easily becomes an operated state than the normal time. When using the regular fuel, a corrected rotational number ΔN is added to a target rotational number Ne* of the engine (S260 and S270). As a result, lowering of power outputted from the internal combustion engine can be more properly coped.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of suppressing the deterioration of exhaust emission resulting from the response delay of an exhaust sensor when automatic start or the return of fuel cut is performed in the fuel injection control device for setting a fuel injection amount so that an actual air-fuel ratio in starting an engine or returning the fuel cut becomes richer than a theoretical air-fuel ratio in the internal combustion engine in which the automatic stop and automatic start of the engine are performed and in the internal combustion engine in which the fuel cut and the return of the fuel cut are performed. SOLUTION: This fuel injection control device is formed to perform air-fuel ratio feedback control when the detection signal of the exhaust sensor after automatic stop is determined to be rich. Also, the detection signal of the exhaust sensor after automatic start is determined not to be rich in the device, it is determined whether a specified time TA is passed from the automatic start or not. When the specified time TA is not passed, the start of the air-fuel ratio feedback control is prohibited and when the specified time TA is passed, the air-fuel ratio feedback control is performed.

Abstract: PROBLEM TO BE SOLVED: To provide a warming-up apparatus of an internal combustion engine for appropriately avoiding a decrease in the recovery efficiency of a heating medium. SOLUTION: The warming-up apparatus of the internal combustion engine is applied to a hybrid vehicle for mounting a navigation system NS, thus supplying cooling water stored in a heat-storing tank 21 to the internal combustion engine 11 via an electric water pump 22, and hence promoting the warming-up of the internal combustion engine 11. When the current location of the hybrid vehicle in the navigation system NS arrives around a destination set to the navigation system NS, the cooling water that absorbs heat in the internal combustion engine 11 and becomes a high temperature is recovered into a heat-storing tank 21 through the electric water pump 22.

SOLUTION: One end of a drive shaft 25 of a compressor 24 is connected to one end of a connection shaft 27 of a motor 26, and a compressor pulley 22 is attached to the other end of the connection shaft 27. A belt 21 is stretched between the compressor pulley 22 and a crank pulley 20 of an engine 11. A one-way clutch mechanism is provided on the compressor pulley 22. When acceleration is requested to the engine 11, the rotational speed of a retainer to be rotated by the motor 26 is set to be higher than the rotational speed of a rotary yoke to be rotated by the engine 11 in the one-way clutch mechanism. The rotary yoke is idled with reference to the retainer, and the load to be transmitted from the compressor 24 to the engine 11 is cut off thereby. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of emission, and to execute electric traveling of traveling by only power from an electric motor in a state that operation of an internal combustion engine is stopped for a longer time. SOLUTION: In this hybrid vehicle 20, when motor traveling of traveling by only the power from the motor MG2 is instructed, a range not more than a comparatively low vehicle speed value V1 is set in a motor traveling executable range when temperature of a purification unit 23 is less than a threshold value Tgref at which exhaust emission can be sufficiently purified, and a range not more than a vehicle speed value V2 having a wider range than the vehicle speed value V1 is set in the motor traveling executable range when the temperature of the purification unit 23 is the threshold value Tgref or above. The motor traveling is made to be executed when a vehicle speed V is within the motor traveling executable range, and the motor traveling is not made to be executed when the vehicle speed V is out of the motor traveling executable range. Thus, when warming-up is not needed, power used for the warming-up of the purification unit 23 is used for the motor traveling. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress charging of an electrical storage device due to excessive power while more properly coping with a charging request of the electrical storage device. SOLUTION: When the excessive power is output from an engine (S120), torque from a first motor is controlled so as to generate power corresponding to a battery charging request power Pb* (S270), while throttle opening control is performed so as to operate the engine by a rotational frequency Neset (S260). Thereby, as compared with the case where normal control is performed by controlling the number of revolutions of the engine by the first motor when efficiently operating the engine under load (S140, S150), the charging of the battery due to the excessive power is suppressed while more properly coping with a charging request of the battery.

Abstract: PROBLEM TO BE SOLVED: To increase a driving force in such a way as not to cause driver discomfort when motor travel is canceled as a driving force required for travel is suddenly increased while the vehicle is driven by motor travel as instructed. SOLUTION: During motor travel using an EV switch 89, if required torque Tr* becomes equal to or greater than EV cancellation torque Tcan and the motor travel is canceled, execution torque T* for use in control is set using a rate value Trt1 for motor travel, until the execution torque T* reaches motor-travel upper-limit torque Tevmax which is smaller than the EV cancellation torque Tcan (S280, S290). After the execution torque T* has reached the motor-travel upper-limit torque Tevmax and until the required torque Tr* is reached, the execution torque T* is set using a rate value Trt2 that is smaller than the rate value Trt1 (S300 to S320). In this way, it is possible to avoid driver discomfort due to slowness or sudden increases in torque. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To further improve fuel efficiency by reducing energy consumption due to rotational speed control that is performed when an automatic transmission part is held in a neutral state in order to secure controllability in switching the automatic transmission part to a state of power transmission. SOLUTION: If the automatic transmission part 20 is held in a neutral state while an engine 10 is maintained in a predetermined operating condition, the rotational speed (second motor rotational speed nmg2) of a transmission member 18 is controlled by a first motor generator MG1 to reach a predetermined target rotational speed nmtag in order to secure controllability for a shift from N to D. The total energies consumed by the engine 10 and the first motor generator MG1 are taken into consideration and the target rotational speed nmtag is determined while the oil temperature Toil of operating fluid and the rotational speed NOUT of an output shaft are used as parameters in such a way that the total energies are minimized, so that energy consumption due to the rotational speed control of the transmission member 18 at neutral is reduced to further improve fuel efficiency.
