Throttle control apparatus for internal combustion engine

A throttle control apparatus for an internal combustion engine, comprising:

• an electronic control type throttle for controlling operation of an internal combustion engine;
• throttle opening degree detecting means for detecting an opening degree of said electronic control type throttle;
• and
• control means for controlling said opening degree of said electronic control type throttle to a target value in dependence on operation state of said internal combustion engine,
• wherein said throttle opening degree detecting means comprising:
• a throttle opening degree sensor for generating a sensor voltage corresponding to said opening degree of said electronic control type throttle;
• offset means for transforming said sensor voltage into a plurality of offset-weighted voltages;
• an A/D converter for performing A/D conversion (analogue-to-digital conversion) of said plurality of offset-weighted voltages;
• and
• adder means for executing processing of adding said plurality of offset-weighted voltages resulting from said A/D conversion,
• wherein a sum value resulting from the addition of said plurality of offset-weighted voltages undergone said A/D conversion is detected as the opening degree of said electronic control type throttle destined to be controlled.
