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.
