PURPOSE:To prevent control lug by prohibiting feeding a stepping motor with a driving signal to fuel incremental side only when the rotational position of a control lever and the number of steps in the stepping motor having both attained respective set values. CONSTITUTION:When the number of steps in a stepping motor 4 and the rotational position of a control lever 3 have both attained their specified values, a prohibiting means 10 prohibits feeding a control means 5 with drive pulses as command into the fuel incremention side. Thus the motor 4 and lever 3 do not rotate any more to the fuel incremental side. In case either of the number of steps and the rotational position remains out of attainment of the set value, the prohibiting means 10 does not operate, and normal constant-speed running control is carried out until the two attain the set values. This allows control after accel. pedal stamping is interrupted to be made early in an amount corresponding to rotation to the fuel incremental side. |
