Abstract
To provide an electronic throttle valve control apparatus which has a high throttle valve opening resolution, and which can be manufactured at a low cost. The apparatus for controlling an electronic throttle valve in which a throttle valve provided in a suction path of an engine is driven to be opened and closed by a motor, includes: a target throttle opening computation unit for computing a target throttle opening of the throttle valve; an actual throttle opening detector for detecting an actual opening of the throttle valve; a control-use actual throttle opening computation unit for computing a control-use actual throttle opening by adding a predetermined number of times the actual throttle opening detected value obtained by the actual throttle opening detector; and a throttle valve controller for controlling the throttle valve on the basis of an opening deviation between the target throttle opening and the control-use actual throttle opening.
