Abstract: When a learned KCS value has a large variation, ISC learning control is performed in an accelerated learn mode allowing ISC learning to be updated in a large amount and fast performed (step ST3-ST5 and ST9-ST11). ISC learning control thus performed in the accelerated learn mode allowing ISC learning to be fast performed can immediately follow the large variation of the learned KCS value and thus allows a learned ISC value to converge to an optimum learned ISC value in a reduced period of time. This allows ISC learning control performed in a hybrid vehicle at idle to be completed in a short period of time to allow idle stop to more effectively enhance fuel economy.

Abstract: PROBLEM TO BE SOLVED: To provide a control system for an internal combustion engine preventing a stall without impairing operation feeling even if an accelerator is rapidly opened under a no-load condition of the internal combustion engine.
SOLUTION: In the control system for the internal combustion engine controlling the operation of an electric motor (actuator) driving a throttle valve installed in an intake pipe of the engine, actual throttle opening TPS, accelerator opening APS, and engine speed NE are detected (S10, S12), target throttle opening THd of the throttle valve is calculated (S20) based on the detected accelerator opening APS and the engine speed NE, and the operation of the electric motor is controlled (S36, S38) so that the detected actual throttle opening TPS becomes the calculated target throttle opening THd when it is determined that the engine is under the no-load condition (S32).

Abstract: This invention is a method and system for a hybrid electric vehicle adaptive fuel strategy to quickly mature an adaptive fuel table. The strategy adaptively alters the amount of fuel delivered to an internal combustion engine to optimize engine efficiency and emissions using engine sensors. Before the adaptive fuel strategy is permitted, an engine "on" idle arbitration logic requires the HEV to be in idle conditions, with normal battery state of charge, normal vacuum in the climate control and brake system reservoir; and, the vapor canister not needing purging. The strategy orders the engine throttle to sweep different airflow regions of the engine to adapt cells within the adaptive fuel table. In the preferred configuration, a generator attached to the vehicle drive train, adds and subtracts torque to maintain constant engine speed during the throttle sweeps.

Abstract: エンジンを始動した後、触媒暖機のために点火時期の遅角を開始し、点火時期θが閾値θrefまで遅角されたときに燃料噴射量の増量補正を開始するために燃料増量フラグF1に値1をセットする。そして、スロットル開度THを増加させ、スロットル開度THの増加が終了してから所定時間t3だけ経過したときに燃料噴射量の増量補正を終了する。これにより、必要に応じて燃料噴射量の増量補正を行なうことができる。この結果、燃費の向上を図ることができると共にエミッションの悪化を抑制することができる。

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device which suitably achieves both highly accurate learning of the variation in injection characteristics of fuel injection valves of cylinders and providing learning in a short period of time.
SOLUTION: The control device calculates a correction quantity FCCB for correcting a rotational variation between cylinders at idle stabilizing control and suppresses the rotational variation between the cylinders by using this (Step S18). When the M-time average value ΔAVE of the variation in the correction quantity FCCB is judged to be a threshold value α or less (Step S26: YES), the correction quantity FCCB is determined to be stabilized, in which the correction quantity FCCB is determined as a learning value of the variation in injection characteristics between cylinders (Step S28).
