    Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of the purification function of a purification device installed in a hybrid car. SOLUTION: When an S position is selected as a shift position, and an accelerator opening Acc is a value 0, and the oxygen occlusion of a purification device for purifying the exhaust gas of an engine is within the extent of below a threshold (S120), the motoring of the engine is performed at the target number of revolutions while fuel supply is stopped, and motoring control for controlling the engine and motors MG1 and MG2 is executed so that braking torque based on a request braking torque can be output to a driving shaft (S130 to 200), and when the oxygen occlusion exceeds the threshold, the target number of revolutions of the engine is set as the idle number of revolutions restricted in comparison with the case of motoring control (S210), and the engine is operated by the set target number of revolutions. Thus, the number of revolutions of the engine is restricted when the deterioration of the purification function of the exhaust gas of a purification device is predicted so that the quantity of oxygen to be supplied to the purification device can be reduced.

    Abstract: PROBLEM TO BE SOLVED: To inhibit excess supply of fuel at a time of start of an internal combustion engine. SOLUTION: An automobile 20 is provided with an engine 22 provided with a cylinder fuel injection valve 25 connected to a delivery pipe 66 provided with a fuel pressure sensor 69 and injecting fuel supplied by a fuel pump 62. The automobile 20 improves startability of the engine 22 by driving a fuel pump 62 before driving a high pressure pump 64 and performing pre-supply process supplying fuel to the high pressure pump 64 when it is judged that fuel does not leak from the cylinder fuel injection valve 25 at a time of start of the engine 22. On the other hand, the pre-supply process is not performed to inhibit fuel leak from the cylinder fuel injection valve 25 when it is judged that fuel leaks from the cylinder fuel injection valve 25.

    Abstract: PROBLEM TO BE SOLVED: To execute idle stabilization correction of an internal combustion engine without risk of stalling the internal combustion engine. SOLUTION: An engine ECU sets time constant τ corresponding to elapsed time t to a value smaller than time constant τc after time tc (S310), and calculates idle stabilization reference Nref according to the equation of Nref=previous Nref+(Ne-previous Nref)/τ (S320). Until the time tc is reached or until idle stabilization correction is started, steps 300-330 are repeated. According to this, the idle stabilization reference Nref rapidly gets close to rotating speed Ne of an engine 22. When the time tc is reached a difference ΔN is calculated by subtracting the idle stabilization reference Nref from the rotating speed Ne of the engine 22 (S340), an ignition timing correction quantity (a) corresponding to the difference Δ N (S350) is determined, and the ignition timing is corrected based on the ignition timing correction quantity (a) (S360).

    Abstract: PROBLEM TO BE SOLVED: To notify an operator that it is necessary to change a shift position in order to stop an internal combustion engine while suppressing the generation of abnormal sound. SOLUTION: When a shift position is any other position of a P(parking) position, and ignition is turned off, a CPU 72 continues the operation of an engine 22, and makes a speaker 96 output a warning sound, and notifies the operator that it is necessary to change the shift position to the P position by displaying a message at a character display part 94 of a display device 90. Then, when the shift position is changed to the P position, the engine 22 is made to stop while motors MG1 and MG2 are controlled so that the generation of any abnormal sound (tooth clicking sound or the like) to be generated due to torque fluctuation from the engine 22 can be suppressed. Especially, when ignition is turned off at an N (neutral) position where any torque cannot be outputted from the motors MG1 and MG2 under the stop control of the engine 22, the operator is promoted to change the shift position from the N position.

    Abstract: PROBLEM TO BE SOLVED: To surely start an internal combustion engine and to suppress resonance generated in the start of the engine. SOLUTION: When a battery temperature Tb does not exceed a threshold value Tb1 or a battery output limit Wout does not exceed a threshold value W1 in the start of the internal combustion engine, that is, when it is possible that motoring of the engine is not normally performed depending on a state of a battery, a fuel injection control is started before an engine speed Ne exceeds a threshold value Nref larger than a resonance speed area (S120 to S140) to start the engine. Therefore, the engine is surely started. On the other hand, when the battery can normally perform the motoring of the engine, the fuel injection control is started after the engine speed Ne exceeds the threshold value Nref larger than the resonance speed area (S120 to S140) to start the engine. Therefore, the resonance generated in the start of the engine is suppressed. COPYRIGHT: (C)2006,JPO&NCIPI
