摘要： An idling speed control method which is adapted to detect by detecting means predetermined rotational angle positions of an internal combustion engine having supplementary air supply control means that regulates the quantity of supplementary air being supplied to the engine, and to control the ratio of operating duty of the supplementary air supply control means to an interval of time at which pulses of a signal indicative of the predetermined rotational angle positions are generated, in a feedback manner responsive to the difference between actual idling engine speed and desired idling speed. When an abnormality is detected in the detecting means, which includes a sensor for sensing the predetermined crank angle positions, a maximum quantity of supplementary air is supplied to the engine by operating the supplementary air quantity control means to its operating limit. The supplementary air supply control means may comprise either (1) a solenoid valve disposed in a supplementary air passage, one end of which communicates with an intake passage of the engine at a location downstream of a throttle valve arranged in the intake passage and the other end communicates with the atmosphere, or (2) a negative pressure-operated means disposed for operating the throttle valve to open or close in response to negative pressure in the intake passage at a zone downstream of the throttle valve, and a negative pressure control means for controlling the magnitude of negative pressure in the intake passage acting upon the negative pressure-operated means.

摘要： An idling rpm feedback control method for controlling the quantity of supplementary air being supplied to an internal combustion engine, in a feedback manner, responsive to the difference between actual engine rpm and the desired idling rpm. When the engine rpm drops to a predetermined rpm being the upper limit of the desired idling rpm, the above feedback control is initiated. When the engine is decelerated with the throttle valve fully closed, and before the feedback control is started, the supplementary air quantity is controlled in decelerating mode in a predetermined manner while the engine speed drops from a predetermined rpm larger than the upper limit of the desired idling rpm to the same upper limit. In case deceleration is continued without disengagement of the power transmission means of the engine, even if the engine rpm drops below the above upper limit of the desired idling rpm, deceleration mode control of the quantity of supplementary air is continued until the power transmission means is disengaged.

摘要： A fuel supply control method for electronically controlling the air/fuel ratio supply to an engine, in response to the output from means for detecting concentration of an ingredient in exhaust gases from the engine. When the engine is in a feedback control region, the air/fuel ratio control is effected by the use of a first coefficient, the value of which is variable in response to the output from the exhaust gas ingredient concentration detecting means, while simultaneously a mean value of values of the first coefficient applied during the feedback control operation is calculated for use as a second coefficient. The second coefficient and a predetermined value are used for control of the air/fuel ratio, in place of the first coefficient, respectively, when the engine is in a first one of the particular operating regions and when the engine is in a second one of same. Preferably, when there is a transition of the operating condition of the engine from one of the particular operating regions to the feedback control region, the air/fuel ratio control is initiated by the use of a second predetermined value other than the above predetermined value, preferably the above second coefficient, in place of the first coefficient. Further, preferably, when the engine is in an idling region as the above second particular operating region, the air/fuel ratio is further corrected by a correction variable corresponding to a preset voltage supplied from a variable voltage creating means.

摘要： A method of controlling an operating amount of an operation control means for controlling the operation of an internal combustion engine having an intake passage and an intake air quantity control means for adjusting the opening area of the intake passage to thereby regulate the quantity of intake air of the engine. The operating amount of the operation control means, such as a fuel injection control means, is controlled to required values dependent on operating conditions of the engine, in synchronism with generation of pulses of a predetermined control signal. When the engine is operating in a predetermined low load condition, a desired operating amount of the control means is determined on the basis of the detected value of the intake passage opening area. A correction value is determined on the basis of a difference between the detected value of the intake passage opening area and the actual value of same, to correct the desired operating amount, and the operating amount is controlled to the corrected desired operating amount. Preferably, the correction value is determined in synchronism with generation of pulses of the predetermined control signal, from the desired operating amount based on the detected value of the intake passage opening area, and a second desired operating amount determined on the basis of the detected values of intake passage pressure downstream of the intake air quantity control means and the rotational speed of the engine. The correction value may alternatively be determined on the basis of a given voltage supplied from a variable voltage-creating means which is humanly adjustable.

摘要： A method of controlling an operating amount of an operation control means for controlling the operation of an internal combustion engine. The operating amount is controlled in a first arithmetic manner determined on the basis of a first operating parameter of the engine during operation in a predetermined operating condition, while it is controlled in a second arithmetic manner determined on the basis of a second operating parameter of the engine during operation in a condition other than the predetermined operating condition. A first correction value appropriate to the first arithmetic manner and a second correction value appropriate to the second arithmetic manner are determined as a function of intake air temperature of the engine, respectively, during engine operation in the above predetermined operating condition, and during engine operation in another operating condition. Preferably, the first operating parameter of the engine is the opening area of the intake passage, while the second operating parameter is pressure in the intake passage at a location downstream of the intake air quantity control means. Also preferably, the first correction value is set to a value as a function of the temperature of intake air upstream of the intake air quantity control means, whereas the second correction value is set to a value as a function of the temperature of intake air downstream of the intake air quantity control means.

摘要： A driver's eye condition detection is conducted by an eye condition detection apparatus including a right/left near-infrared light sources, a camera and an ECU installed therein. The right side near-infrared light source is positioned on a right side relative to the camera in a driver's view, and a light axis of the right side near-infrared light source is tilted to the right by 15 to 45 degrees relative to an imaging direction of the camera. Further, the left side near-infrared light source is positioned on a left side relative to the camera in a driver's view, and a light axis of the right side near-infrared light source is tilted to the left by 15 to 45 degrees relative to an imaging direction of the camera. In this manner, detection errors of the driver's eye condition are reduced.

摘要： A face camera mount structure in a vehicle has a camera for imaging a driver's face being disposed on a reverse side of a dial at a portion that does not interfere with a speedometer design portion on the dial. A camera facing portion of the dial that faces a lens of the camera is covered with a print of a near-infrared light passing ink that selectively passes a near-infrared light. The high transparency factor of the near-infrared light through the ink makes it possible for the camera to image a sufficiently bright near-infrared light image without being recognized by a driver of the vehicle.
