Abstract
A method for emergency control of an internal combustion engine includes simulating signals (pulses or tooth signals are reference signals) of a crankshaft transducer from certain memorized variables, in the event of a failure of the crankshaft transducer. The memorized variables are the total number of teeth, angle lengths of segments (teeth, gaps) disposed on a crankshaft transducer disk, a transit time of the segments of the crankshaft transducer disk, and memorized crankshaft positions corresponding to edges of the segments.
