Abstract
In a method for generating trigger or ignition pulses that control a periodic event of an internal combustion engine, a precalculation is required of a calculated running time T.sub.n+1 that a crank shaft of the internal combustion engine meets in order to traverse the respectively next of prescribed, constant allowed ranges WB.sub.n. For this precalculation, a real running time TE.sub.n is measured after every traversal of one of the allowed ranges WB.sub.n and the next, following running time is precalculated with an approximation. The precalculated value of this calculated running time T.sub.n+1 is derived from the equation:
