PURPOSE:To prevent the generation of an acceleration shock without fail irrespective of the position of a speed change gear by a method wherein the amount of fuel injection is corrected with a correcting value which differs every time when the position of the speed change gear changes, in accordance with the torsional resonance frequency of the drive system of the engine at the time of acceleration of a vehicle when the output shaft of the engine and the drive system are coupled directly to each other. CONSTITUTION:In case an engine is being accelerated, the position of a speed change gear 10 is detected from the output of a shift senser 12 to see whether or not the speed change gear is at its first speed position and to determine whether or not the value of a counter D counting the number of fuel injection times exceeds predetermined values N1-N3 at which the correction of the decreasing or increasing amount of fuel injection is carried out. Thus, when the value of the counter D does not exceed the predetermined values, the counting of the counter D is advanced by one only. Next, a correcting value E of fuel injection time corresponding to the value of the counter D is read out from a table displaying the relation-ship between the number of fuel injection times of acceleration in each of first to third speed stages predetermined in compliance with the torsional resonance frequency of the drive system in that speed stage, and the correcting value of fuel injection time, the correcting value E is added with other correcting values so as to calculate a final injection time and the fuel is injected from an injector 30 in a predetermined timing. |
