Abstract

An engine throttle valve control apparatus whereby a reference throttle valve degree of the opening is established in accordance with the accelerator pedal actuation position and a reference opening degree characteristic. A boundary throttle valve degree of the opening is established in accordance with the accelerator pedal actuation position and at least one upper limit opening degree characteristic and a lower limit opening degree characteristic. A target degree of the throttle opening is computed from the relationship between the reference degree of the opening and a boundary degree of the opening, in conjunction with the contents of a characteristic command which can be freely selected. Thereby throttle valve is driven to reduce the deviation between the actual degree of the opening and the target degree of the opening.
