    摘要： A required fuel amount for an engine is calculated at a predetermined calculation cycle. A fuel injection amount to be injected from an upstream injection valve and a fuel injection amount to be injected from a downstream injection valve are then calculated. After fuel injection on the basis of the calculated fuel injection amounts, a lack of fuel delivered by the fuel injection amounts immediately before re-calculation of a required fuel amount at the calculation cycle until the end of an intake stroke (end of an intake valve opening period), is calculated by subtracting the fuel injection amounts from the re-calculated required fuel amount. The calculated lack of fuel amount is injected from the downstream injection valve during the intake stroke, e.g., in stages 6 and 7. A portion of a fuel injected from each of the fuel injection valves which has adhered on an inner wall of an intake pipe and subsequently released to be later supplied to the engine, is calculated in accordance with a predetermined adhesion ratio and a predetermined release ratio. The above lack of fuel amount is determined in consideration of the calculated portion of the fuel. The lack of fuel amount is additionally injected, e.g. a fuel correction amount, even during an engine transient state, and engine operability and fuel consumption are improved.

    摘要： An oxygen concentration sensor trouble discriminating apparatus in which a counter executes a counting operation every time a lean state of an air-fuel ratio is detected on the basis of an output signal of an oxygen concentration sensor for the first time after a feedback control operating state was not detected. In the case where the air-fuel ratio feedback control operating state is detected, if the output signal of the oxygen concentration sensor indicates an inversion of the rich and lean states of the air-fuel ratio, a count value of the counter is reset to an initial value. When the count value is larger than a predetermined value, the oxygen concentration sensor is decided to be in trouble.

    摘要： To allow an engine having an intake duct for drawing running air to produce a high output by performing appropriate fuel injection depending on dynamic pressure variations. A vehicle speed corrective coefficient calculator calculates a fuel corrective coefficient KVPLS based on a vehicle speed VPLS, and a throttle corrective coefficient calculator calculates a corrective coefficient KV&thgr;TH based on a throttle opening &thgr;TH. A corrective coefficient multiplier multiplies the fuel corrective coefficient KVPLS and the corrective coefficient KV&thgr;TH, thus calculating a vehicle speed fuel adjustment corrective coefficient KVAF. An injection time calculator calculates a basic injection time TiM based on the throttle opening &thgr;TH and an engine rotational speed Ne, and also calculates a fuel injection time Ti by reading the vehicle speed fuel adjustment corrective coefficient KVAF and correcting the basic injection time TiM. When the engine rotational speed Ne is equal to or higher than a predetermined value Ne1 and also when the transmission is shifted to a low gear position, a corrective coefficient KVAF signal is applied to the injection time calculator.

    摘要： Calculating an acceleration corrective in response to a subtle change in a throttle action by utilizing first and second rate-of-change calculators to calculate rates of change D&thgr;THA, D&thgr;THB of a throttle opening in preceding first and second periods (second period>first period) per a predetermined crankshaft rotational angle). A maximum value updater updates a stored value in a maximum value memory with a greater one of past and present maximum rates of change D&thgr;TH of the throttle opening, based on a compared result from a comparator. Points in a plurality of cycles read from a point calculator based on the maximum rate of change D&thgr;TH of the throttle opening are added together and inputted to a corrective value calculator. If the total of points is equal to or greater than a preset value, then an acceleration corrective quantity calculated by the corrective value calculator depending on the maximum value of rates of change of the throttle opening is supplied to a fuel injection time calculator, which calculates a fuel injection time Ti in view of the acceleration corrective quantity.

    摘要： An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop.

    摘要： An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is “0,” and the engine rotational speed of “0” is displayed on the meter.

    摘要： An electronic throttle control system and method are provided. The system includes a throttle valve, a motor configured to drive the throttle valve, and a throttle position sensor configured to detect an angle of the throttle valve. The system further includes an engine rotating speed detector, and a controller. The controller is configured to drive the motor to control the angle of the throttle valve. The controller is configured to initially set a lower limit value of the angle to an angle which is greater than a full closure angle of the throttle valve by a predetermined amount. The controller is further configured to, when a rise in an engine rotating speed is detected, re-set the lower limit value to reduce it by a predetermined amount to control the engine rotating speed to within a predetermined value from the preset idle speed.

    摘要： An operation amount detecting unit 17 detects an operation amount of a throttle grip from a zero position. A basic throttle opening degree computing unit 18 computes a basic throttle opening degree corresponding to the operation amount. A throttle opening degree additional value computing unit 20 outputs as a target throttle opening degree a value obtained by adding the basic throttle opening degree with a throttle opening degree additional value corresponding to the operation amount when the operation of the throttle grip is performed within a small operation region corresponding to an idle operation. The throttle opening degree additional value computing unit 20 outputs as the target throttle opening degree the basic throttle opening degree when the operation of the throttle grip is performed without the small operation region.
