Method for fault-tolerant rotation angle detection

The invention relates to a method for fault-tolerant signal detection with at least three sensors, wherein commutation of the electric motor is executated according to the angular positions of a rotor detected by the sensors, wherein the angular positions are stored for the rotor for specified state...

Beschreibung
Zusammenfassung:	The invention relates to a method for fault-tolerant signal detection with at least three sensors, wherein commutation of the electric motor is executated according to the angular positions of a rotor detected by the sensors, wherein the angular positions are stored for the rotor for specified states of the signals of the three sensors, and states are stored for a defective sensor. A sequence of states is detected, wherein the detected states are compared to the stored states, and based on the comparison, the defective sensor is detected.
