摘要： Disclosed is a method and apparatus for controlling a throttle valve (8) driven by a D.C. motor (3) in an internal combustion engine (1), in which the D.C. motor (3) is driven until a valve position sensor (4) detecting the angular position of the throttle valve generates an output signal which coincides with the output signal of an accelerator pedal sensor (6) detecting the amount of depression of an accelerator pedal of a vehicle. The value (i₁) of motor current required for causing very slight displacement of a return spring (12) provided for returning the throttle valve toward a predetermined angular position is utilized for automatically compensating various factors of fluctuation attributable to friction, inertia, etc. of means (10, 12) driving the throttle valve. A small-capacity microprocessor is used to control the D.C. motor so that the throttle valve can operate with high accuracy and high-speed response capability without being adversely affected by changes in the operating condition as well as secular variations.
