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： To change a fuel injection quantity to follow a throttle opening change in a low load region. A first calculator calculates a basic injection time using a throttle opening and an engine rotational speed. A second calculator calculates a basic injection time using an intake pipe negative pressure and the engine rotational speed. A selector selects the first calculator when the load is higher, and selects the second calculator when the load is lower. If the rate of change of the throttle opening is greater than a reference value, then a switcher sets the selector to select the first calculator. Thus, if the rate of increase of the throttle opening is greater than the reference value even when the load is low, the first calculator is selected.

摘要： In electronically controlling the opening of a throttle valve mounted in an intake system of an engine, the opening is controlled through a sliding mode control, based on a control amount including a control amount portion proportional to the switching function and a control amount portion corresponding to a nonlinear spring torque of a return spring urging said throttle valve in a direction to reduce the throttle valve opening. According to this constitution, the response characteristic of the control unit is maintained while restraining overshoot, enabling the opening to converge to the target opening promptly while sliding along a switching plane. Further, since said control amount includes the control amount portion corresponding to the nonlinear spring torque of the return spring, uncertainty element is reduced, to thereby perform a high response control.

摘要： The apparatus comprises two accelerator position sensors and two throttle position sensors, and when one out of said two accelerator position sensors or said two throttle position sensors fails to operate, a limitation is added to the increase in accelerator position for the output characteristics of the accelerator position sensor. Thereby, the vehicle is enabled to travel at a minimum speed necessary without excessively increasing the engine output. When one of the two throttle position sensors fails to operate, the fuel injection quantity may be set based on the detection value of the accelerator position, which enables the vehicle to be driven by approximately the desired speed without excessively increasing the engine output.
