CONTROL MEANS AND METHOD FOR DETECTING THE ROTATIONAL SPEED OF AN INTERNAL COMBUSTION ENGINE

A method for detecting rotational speeds (n) of an internal combustion engine having a signal wheel having marks (M1 through M7) for signaling on a crankshaft of the internal combustion engine is described. The marks (M1 through M7) on the signal wheel are detected with the aid of a sensor and evalu...

Zusammenfassung:	A method for detecting rotational speeds (n) of an internal combustion engine having a signal wheel having marks (M1 through M7) for signaling on a crankshaft of the internal combustion engine is described. The marks (M1 through M7) on the signal wheel are detected with the aid of a sensor and evaluated by a detection and evaluation device. To implement high-precision detection of a rotational speed, the rotational speeds (n) are evaluated using a sector section of approximately 6° to 35° to increase the accuracy on the basis of a reduced sector section of the signal wheel.
