More Information
Summary:The invention relates to a method for determining an average segment time of an encoder wheel of an internal combustion engine. The encoder wheel is connected in a rotationally fixed manner to a crankshaft of the internal combustion engine, markings are arranged along the circumference of the encoder wheel, and the crankshaft of the internal combustion engine passes over angular regions which are predetermined during segment times, wherein segment times (s1, s2, s3, s4, s5) are detected, associated rotational speed values (n1, n2, n3, n4, n5) are determined from the segment times (s1, s2, s3, s4, s5), a rotational speed profile (231) is determined from the individual, determined rotational speed values (n1, n2, n3, n4, n5), a value of the average rotational speed (n*) is determined from the rotational speed profile (231), and an average segment time is determined from the value of the average rotational speed (n*).
