EVALUATION DEVICE AND METHOD FOR OPERATING A SENSOR SYSTEM EQUIPPED WITH A MAGNETIC SENSOR AND AT LEAST ONE INERTIAL SENSOR

An evaluation device for a sensor system equipped with a magnetic sensor and at least one inertial sensor. The evaluation device includes an electronics device, using which a value of an orientation variable may be determined in view of at least one supplied inertial sensor signal and at least one supplied magnetic sensor signal. Using the electronics device, a comparison value for the at least one orientation variable is determined in view of the inertial sensor signal and in disregard of the magnetic sensor signal. In view of a deviation and/or a correlation coefficient between the value and the comparison value, an information item regarding a reliability of the magnetic sensor signal of the magnetic sensor and/or regarding an occurrence of magnetic and/or electrical interference in a surrounding area of the magnetic sensor, is determined.
