Abstract
A method is proposed for controlling an internal combustion engine having a crankshaft, in which from the angular pulses of a sensor a pulse time is formed that is a measure for the rotation of the crankshaft of the internal combustion engine per time unit. At a predetermined target angle of the crankshaft, an ignition of a spark plug and an injection of fuel are to take place. A charging of an ignition coil before the ignition and the injection each require a predetermined time duration. The charging of the ignition coil and the injection are each started before the target angle at a start time dependent on the crankshaft, the start times being calculated by taking into account the time duration of the charging and of the portion of the injection before the target angle, and the pulse time, and the pulse counter. The same pulse time is used for the calculation of the start times of the charging of the ignition coil and of the injection.
