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.

摘要： In a method and apparatus for fail-safe controlling an electronically-controlled throttle-type internal combustion engine, provision is made of two accelerator position sensors and two throttle position sensors. When either one of the two accelerator position sensors or either one of the two throttle position sensors fails to operate, a low-speed fail-safe operation of a minimum compensation, that is, an operation for maintaining a minimum output required for limp-home control operation of the engine, is executed and, then, a first fail-safe control operation is executed for controlling the position of the throttle valve using a value detected by the remaining sensor. Therefore, the throttle valve is not unintentionally opened, and the operation can be smoothly shifted to the first fail-safe control operation. When the operation for decelerating the engine is detected by a sensor of a system separate from the above-mentioned sensors, the first fail-safe control operation is interrupted and, instead, a second fail-safe control operation is executed for holding the throttle valve at a predetermined position in order to assure the low-speed fail-safe operation of the minimum compensation.

摘要： With engine control apparatus for controlling a throttle opening and fuel injection quantity in order to realize a target engine torque according to the present invention, in the case where a target air-fuel ratio is changed in accordance with a change in the target engine torque, erroneous control of the fuel injection quantity is prevented. To achieve this, a target fuel quantity and a target air-fuel ratio are set based on the target engine torque, and a target air quantity is computed from the target fuel quantity and the target air fuel ratio. A target throttle opening is then computed based on the target air quantity, to control an electrically controlled throttle valve. Meanwhile, an actual air quantity detected by an air flow meter is smoothed, and a cylinder charge air quantity computed. The target air-fuel ratio is then corrected using a ratio of the cylinder charge air quantity to the target air quantity. A target fuel injection quantity is then computed from the cylinder charge air quantity and a post correction target air-fuel ratio, to control a fuel injector.

摘要： A difference is obtained between a cylinder pressure during the compression stroke when an exhaust gas recirculation control valve is opened, and a cylinder pressure during the compression stroke when the exhaust gas recirculation control valve is closed. An estimated value for this difference is set from a cylinder pressure detected under the closed conditions and an exhaust gas recirculation proportion. When the difference is smaller than the estimated value, it is assumed that the exhaust gas recirculation quantity is not changing in accordance with open/close control, and the occurrence of a fault in the exhaust gas recirculation unit is thus judged.

摘要： A rate of change in the combustion pressure in each of the cylinders is calculated based upon a result detected by a combustion pressure sensor provided for each of the cylinders. The air-to-fuel ratio is increased and/or the ignition timing is retarded for each of the cylinders so that a rate of change in the combustion pressure approaches a value corresponding to the combustion stability limit in each of the cylinders.

摘要： A standard deviation and mean value of a value for the cylinder pressure integrated over a predetermined interval are computed. A value for the standard deviation divided by the mean value is then made an index value for judging a limit of output fluctuations. When the index value is less than a predetermined value corresponding to the output fluctuations, then weakening of the air-fuel ratio and retarding of the ignition timing is proceeded, while when the index value is equal to or greater than the predetermined value, it is judged that the limit of the output fluctuations has been exceeded, and the air-fuel ratio is corrected to the rich side, and the ignition timing is corrected to the advance side.

摘要： An air fuel ratio control system is so arranged to restrain a undesired variation of an air fuel ratio due to an on off control of a canister purge and thereby prevent deterioration of an exhaust performance. When a purge cut valve is closed to cut off the canister purge, the control system changes a feedback air fuel ratio corrective factor ALPHA like a step change to a predetermined initial value EVALP# to meet a leaning change of the air fuel ratio caused by the purge cut. When the purge cut valve is opened to resume the canister purge, the control system meets an enriching change of the air fuel ratio caused by restarting of the purge by producing a step change in the corrective factor ALPHA to an initial value EALPHA.times.KEVAL# determined in accordance with a value EALPHA of the corrective factor ALPHA obtained immediately before the cutoff (KEVAL# is a constant).
