ABSTRACT:
A spark-advance angle of an internal combustion engine is calculated based on at least one electrical signal which indicates an operating condition of the engine. The calculated spark-advance angle is compared with a lower limit of a required spark-advance angle, and then, if the calculated spark-advance angle is less than the lower limit, this calculated spark-advance angle is corrected so that it coincides with the lower limit.
