ABSTRACT:
A fuel injection control apparatus of an internal combustion engine having reduced erroneous determination and delay of discriminating/updating a gear position and thus having improved accuracy of its gear position information. The apparatus has a gear position sensor for detecting a gear position; a vehicle speed pulse sensor for detecting a vehicle speed pulse; an engine speed sensor for detecting an engine speed; first gear position calculator for determining a gear from data from the gear position sensor; second gear position calculator for determining a gear on the basis of data from the vehicle speed pulse sensor and data from the engine speed sensor; and gear position selector for deciding a gear position on the basis of the logical product of the gear position determined by the first gear position calculator and the gear position determined by the second gear position calculator.
