摘要： A fuel injection control apparatus is capable of supplying a proper amount of fuel by improving response when the throttle position is abruptly changed. The fuel injection control apparatus includes an electronic control unit for determining a fuel injection time period for a fuel injection system, based on the engine speed and the throttle position. The electronic control unit is operable to determine a base fuel injection time period based on engine speed and throttle position to start fuel injection, and adjusts the initial fuel injection time period thereafter, based on changes in the engine speed and the throttle position.

摘要： The present invention enables reliable shift to a fail-safe processing upon detection of failure by RAM diagnosis. To this end, the diagnosis result of the RAM diagnosis is doubly stored, as flags, into mutually different two addresses of the RAM; and a fail-safe processing is conducted based on the doubly stored diagnosis result flags when at least one of the flags indicates existence of failure. Otherwise, the diagnosis result of the RAM diagnosis is stored, as a flag, into a predetermined register; and a fail-safe processing is conduced based on the diagnosis result flag stored in the register such that the fail-safe processing is conducted when the flag indicates existence of failure.

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.
