Abstract:
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.
