摘要： PURPOSE:To suppress a pulsation of intake air in the upstream of a throttle valve while improve a response characteristic in an engine when it is decelerated, by minimizing a target throttle valve opening for realizing a target air quantity in consideration of an engine speed. CONSTITUTION:A map in a control unit 25 determines, for a depressing distance of an accelerator pedal 5 detected by an accelerator pedal position sensor 19, a target air quantity which considers a correction for the maximum air quantity determined by a cooling water temperature, detected by a water temperature sensor 23, and an engine speed when a throttle valve 6 is fully opened. The map, from an intake air quantity per one cylinder obtained from said target air quantity and the engine speed, determines the minimum throttle valve opening required for realizing the target air quantity. In this way, an obtained signal of the target throttle valve opening, being output to a throttle actuator 7, controls the throttle valve 6.

摘要： PURPOSE:To eliminate the torque shock on advance or in low-speed traveling by installing a characteristic correcting means which receives the output of an acceleration detecting means and limits the correction by the characteristic correcting when the accelerator operating amount is less than a prescribed value. CONSTITUTION:A calculating means 41 receives the output of an acceleration detecting means 40 and calculates the aimed opening-degree of a throttle valve 43. When the variation speed of the accelerator operating amount is over a set value, a characteristic correcting means 44 receives the output of the acceleration detecting means 40 and corrects the aimed opening-degree to a large value. In this case, a characteristic correction limiting means 45 receives the output of the acceleration detecting means 40 and limits the correction by the characteristic correcting means 44 when the accelerator operating amount is a prescribed amount or less. Thus, the generation of torque shock on advance or in low-speed traveling can be eliminated.

摘要： PURPOSE:To enhance safety, by providing a means for setting an upper limit value to compensation in the feedback control of a throttle valve, to prevent uncontrolled operation at the time of defectiveness of a sensor. CONSTITUTION:An aimed throttle valve opening degree theta1 or an aimed intake quantity Ac1 is determined depending on the operated quantity alpha of an accelerator. The degree thetaR of opening of a throttle valve is feedback-controlled to be equal to the aimed opening degree theta1. A means 37 for setting an upper limit value Camax to compensation in the feedback control of the throttle valve is provided. When a compensated value in the feedback control of the throttle valve exceeds the upper limit value Camax, the feedback compensation is stopped. Uncontrolled operation at the time of defectiveness of a sensor for detecting the degree of opening of the throttle valve or the quantity of intake is thus prevented to enhance safety.

摘要： PURPOSE: To enhance the driving characteristics by furnishing an air-fuel ratio change rate getting means, which is to alter the change rate of the air-fuel ratio when it is changed over, upon receiving the output of a throttle change rate sensing means, and thereby eliminating uncomfortable variation of the torque.
CONSTITUTION: In this system the operating range is divided into a section with smaller air-fuel ratio and another with larger air-fuel ratio. An air-fuel ratio changeover means changes over the air-fuel ratio upon receiving the output of an operating range sensing means. An air-fuel ratio setting means receives the output of a throttle change rate sensing means, and increases the change rate of air-fuel ratio at the time of changing over the air-fuel ratio, wherein the change rate shall be greater as the change rate of throttle opening increases. Thus uncomfortable variation of the torque can be eliminated when the opeerating range is switched, which will well enhance the driving characteristics.

摘要： PURPOSE:To prevent the air-fuel ratio from becoming over-rich, by interrupting fuel increase for a predetermined while after effecting fuel increase corresponding to the depth of the first depression of an accelerator pedal at the time of accelerating an engine by depressing the accelerator pedal repeatedly. CONSTITUTION:A fuel control means 8 such as a fuel injection valve is disposed in an intake passage 5 on the upstream side of a throttle valve 7. In case that the degree of change in the opening of the throttle valve is higher than a prescribed value and it is judged by an acceleration detecting means 20 that an engine is in acceleration, control is made to increase the injection quantity of fuel by an acceleration fuel increasing means 21. Further, a predetermined period after control of increasing fuel for acceleration by the means 21 is terminated is detected by a period detecting means 22. When the engine is within the above predetermined period, control of increasing fuel for acceleration by the acceleration fuel increasing means 21 is interrupted by a means 23 for interrupting fuel increase for acceleration. With such an arrangement, it is enabled to prevent the air-fuel ratio from becoming over-rich due to repeated fuel increasing caused by repeated depressions of an accelerator pedal.

摘要： PURPOSE:To enhance the reliability of engine operation, by cancelling constant-speed operation when some engine trouble is detected from parameters relating to the reliability of engine operation such as temperatures of catalyst, lubricating oil, cooling water, etc. in the titled apparatus including a constant-speed driving means. CONSTITUTION:When a constant-speed operation switch 9 is turned ON, a switching circuit 12 is shifted to the position shown by the solid line in the drawing, and an amplified output of a vehicle-speed setter 4 and an amplified deviation between the output of the vehicle-speed setter 4 and that of a vehicle-speed detector 5 are added at an adder 8 of a constant-speed operation control means 21. The added value is applied to a differential amplifier 13 together with the output of a throttle valve opening detector 19, and the opening of a throttle valve 18 is controlled automatically by controlling a DC motor 17 according to a constant-speed operation control signal (a) obtained from the deviation. Here, if the temperature of a catalyst means disposed in the exhaust system is raised extraordinarily during the constant-speed operation of the engine, a catalyst temperature switch 10 is turned ON, and the switching circuit 12 is shifted to the position shown by the broken line in the drawing by an AND-circuit 11 to which an inverted signal of the switch 10 is applied.
