PURPOSE:To prevent a jerky vibration from occurring, by installing both of a torsional vibro-variation operation device calculating a variation in a torsional vibration value and an air-fuel ratio compensation device compensating the air- fuel ratio in an engine according to the variation in the torsional vibration value. CONSTITUTION:A torsional vibration value detection device detects a torsional vibration value in a driving system in an internal-combustion engine, while a torsional vibration comparator device compares the said torsional vibration value with the specified value, and a vibro-variation operation device calculates a variation in the torsional vibration value. In consequence, when the torsional vibration value goes up beyond the specified value, an air-fuel ratio compensation device compensates the air-fuel ratio in an engine only for a specified time according to the variation in the torsional vibration value. With this constitution, torque variations due to the torsional vibration is thus offset so that a jerky vibration is prevented from occurring. |
