ツトル弁制御装置。 The step motor is equipped with an accelerator opening sensor that detects the accelerator opening, a step motor that drives and controls the throttle valve, and a constant current drive circuit that drives the step motor at a constant current based on the output signal of the accelerator opening sensor. 2 after the motor is energized for 1 phase
In a throttle valve control device for an internal combustion engine which is rotated by one-phase excitation after a phase excitation state, there is provided an engine stop determination means for determining whether the engine is stopped, and a step motor whose excitation state is one-phase. and an excitation state discriminating means for discriminating whether or not the excitation state is in the excitation state, and when the engine is stopped based on the discrimination results of the engine stop discriminating means and the excitation state discriminating means, the step motor is operated in the one-phase excitation state. A throttle valve control device for an internal combustion engine that keeps it stationary.
