摘要： PURPOSE:To accurately calculate a learning correction value of an intake air amount control valve by suppressing quick increasing a power generating quantity, and further deciding an electric load for whether provided or not based on a current value of a generator or the like, to also calculate a value reduced corresponding to the electric load, when the electric load is applied during idle operation. CONSTITUTION:In an intake pipe.2 of an engine 1, a throttle valve 2 and a bypass passage 4 of bypassing this valve are arranged. An ISC valve 5 for controlling an idle speed is arranged in the bypass passage 4. Further in an engine control unit 7, based on output signals from various sensors and switches for detecting an operating condition of the engine 1, the ISC valve 5 and an alternator (generator) 8 are controlled. Here during idle operation, when an electric load is applied, quick generating a generating quantity in the generator 8 is suppressed, and further based on each current value of the generator 8 and a battery, whether the electric load is provided or not is decided. A value corresponding to the electric load is calculated to be reduced, to accurately calculate a learning correction value of the ISC valve 5.

摘要： PURPOSE:To reduce efficiently shock and shaking due to acceleration, by calcu lating the correctional amount of an ignition timing so that the difference be tween the smoothing rotational speed and the instantaneous rotational speed of an engine may become smaller, and also correcting the correctional amount on the basis of an idling operation condition. CONSTITUTION:The instantaneous rotational speed of an engine is calculated at an operation unit 54 on the basis of a detection signal from a TDC sensor. Also, the filter operation of the detection signal from the TDC sensor is made at an operation unit 55, and a smoothing rotational speed opposing to the instan taneous rotational speed is calculated. In addition, a rotational variation which is obtained by subtracting the instantaneous rotational speed from the smoothing rotational speed, is calculated by an operation unit 56. Meanwhile, at a calculat ing unit 59, the basic ignition timing thetaB is corrected to a correctional ignition timing thetaC on the basis of detection information or the like from an intake air temperature sensor 18, an atmospheric pressure sensor 19 and a water temper ature sensor 43 or the like. In a calculating unit 60, a target ignition timing is calculated from the rotational variation band and the correctional ignition timing.

摘要： PURPOSE:To prevent an engine stalling by detecting the descending speed of engine speed at the time of decelerated operation during fuel cutoff, and in case of this descending speed being over the specified value at the fuel supply resuming time, increasing fuel supply at the resuming time over the specified period. CONSTITUTION:At the time of operating an engine 12, an electronic control device judges whether or not the engine 12 is in the specified decelerated operation on the basis of the detection signals of various sensors, and upon judging negative, computes the fuel injection quantity corresponding to the operated state so as to perform the valve opening control of each fuel injection valve. In the case of judging affirmative, the electric control device executes fuel cutoff control, and when the specified release condition is satisfied during fuel cutoff, resumes fuel supply while judging the required fuel increase quantity at the reset time. In this case, the descending speed of the engine speed at the time of the engine being in the specified decelerated operation is detected previously, and when this descending speed is over the specified value at the time of resuming fuel supply, the fuel supply quantity at the resuming time is controlled to be increased over the specified period.

摘要： PURPOSE:To restrain a shock in re-starting of fuel supply by controlling to temporarily increase an output of an engine after re-start of the fuel supply if an engine speed deflection between an instant engine speed and smoothed engine speed exceeds an allowable deflection value. CONSTITUTION:In a fuel supply controller for controlling the operation of a fuel supply means in such a manner as to stop fuel supply when a vehicle is under a preset deceleration operation condition and for controlling the operation of the fuel supply means in such a manner as to re-start the fuel supply when the vehicle attains the preset operation condition by means of an ECU 20, the ECU 20 calculates an instant engine speed of an engine during stoppage of the fuel supply and a smoothed engine speed of the engine at this time, to thus calculate a deflection between both engine speeds. If the engine speed deflection exceeds an allowable deflection value, an advance quantity of an ignition timing of an ignition device 35 serving as an output control means is increased in such a manner as to temporarily increase an output of the engine after the re-start of the fuel supply.

摘要： PURPOSE:To provide optimum supercharging condition according to the car running condition by controlling the operation of an exhaust turbo-charger so that the supercharge pressure becomes below the set level, and making the set pressure value variable according to the speed of the car. CONSTITUTION:A turbo-charger 12 is constructed in such a constitution that a compressor 14 installed on a suction passage 4 is directly coupled with a turbine 20 installed on an exhaust passage 20 through a shaft 13. A bypass 22 detouring the turbine 20 is provided on an exhaust passage 8, and a waste gate valve 24 is installed on the way of this bypass 22. This valve 24 is driven by an actuator 28, and its pressure chamber 34 is leading to a suction passage 2 downstream an intercooler 16 through a passage 38 and also to that portion of suction passage 2 which is situated upstream the compressor 14 via a solenoid valve 42. The set value of supercharge pressure can be varied by controlling this solenoid valve 42, which is controlled by an ECU 44 according to the output of a car speed sensor 48.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of backlash strike shock, the increase of an engine brake feeling, and lowering of re-accelerating ability, and to perform a coast down shift. SOLUTION: When a coast down shift is performed by an ECU for A/T 25, 30 to reduce an engine output independently from operation of a driver, the number of revolutions of an engine is suppressed to a value lower than the number of input revolutions of an automatic transmission 18 by reducing the output of an engine 1 from the starting of the coast down shift. Even in the case when the coast down shift is effected in the vicinity where the number of idle revolutions changes into a high rotation area, the behavior wherein the number of revolutions at the starting of a speed change is reduced to a value lower than the number of revolutions of an engine is prevented from occurring.
