Abstract: PURPOSE:To promptly correct a valve lower limit opening to a target idle speed opening, by preventing a lower limit value from correcting a study value to be limited till it coincides with an ISC valve opening when resetting of a volatile memory power supply is detected after it is removed. CONSTITUTION:The method, cancelling a study value PG being stored in BU- RAM if a battery is removed at time t1 and resetting the battery at time t2, gives an initial value to an opening P and the study value PG if a switch is turned on at time t3. And the method by feedback control corrects the opening P to be reduced by a step alpha by alpha while the study value PG to be reduced by a step gamma by gamma, but the method holds the opening P to an opening PG-beta till time t5 when the PG-beta reaches the opening corresponding to a target idle speed because the opening P is limited to the lower limit opening PG-beta at time t4. The method, preventing during this time the study value PG from being limited by a lower limit value PGMIN and gradually decreasing the study value to be corrected, finishes a study by obtaining a relation where PG=P at time t6. Accordingly, the method improves the efficiency of fuel consumption by promptly decreasing also the lower limit opening of an ISC valve to be corrected to a suitable value.

Abstract: PURPOSE:To prevent drop of engine rotational speed or stall at transition of an increase in load, by increasing a target air amount for a predetermined time according to the engine rotational speed when racing is stopped and load is added under an idling condition with light load. CONSTITUTION:Under the condition that engine rotational speed NE is high with racing at N range, when the racing is stopped to select D range, the rotational speed NE is lowered. Compensation control of air amount by an increased opening angle PND is started according to the rotational speed NE at the selecting operation, and an output opening angle POUT of an ISC valve 16 is set to (Po+ Pe+PND) after the time of T0, where P0 is a fundamental opening angle for feed- back control of the ISC valve 16; Pe is an estimated opening angle for feed- forward control; and P0+Pe is a target opening angle P. The output opening angle POUT is decreased to the target opening angle P after the retention time of T, and is shifted to be controlled at a stationary state. Then, the rotational speed NE smoothly reaches a target rotational speed at the D range.

Abstract: PURPOSE:To make improvements in transient controllability as well as to make the stable idling operation of an engine performable, by controlling an idling speed in a way of multivariable part control by means of a low dimension, approximated dynamic model, while absorbing a portion for approximate errors with an integrating action. CONSTITUTION:A state observation apparatus 13 stores a low dimension, approximated dynamic model for an engine being subject to control and inputs those of data on pulse width PA driving a control solenoid for a VCM valve, ignition timing IT and idling speed N, then calculates an estimated value x' of a state variable X representing the inside state. And, with an integrating action, a gain block 14 inputs the estimated value x' and a deviation between the idling speed N and a desired value Nr, and then controls the idling speed with the control signal PA and the ignition timing IT by a proportional integrating action. With the idling speed made into approximation like this, counting time is shortened, while a portion for approximate errors is absorbed by the integrating action and, what is more, a controlling transient response is optimized, thus stable idling speed control comes to fruition.

CONSTITUTION:An electronic fuel injection controlling device operates such that in ECU40 the basic fuel injection time obtained from the outputs of a throttle sensor 22 and a crank angle sensor 36 is corrected by the oututs of a sucked air temperature sensor 16 and an O2 sensor 32 and an injector 28 is controlled on the base of the actual fuel injection time as corrected. In this case, an idle-up device 42 adopted to change the fully closing position of the throttle valve 20 in proportion to the temperature of cooling water. The device 42 causes a stopper 78 to rotate clockwise through the action of a return spring 80 at the time of cooling the engine to thereby regulate the fully closing position of the valve 20 toward the opening side of the valve while when the heating of the engine is finished, it causes the stopper 78 to rotate against the force of the spring 80 through the expansion of a thermo-wax so as to set the fully closing position of the throttle valve at the usual closing position.
