System and method for sensor data validation

A sensor system, comprising:

• a plurality of sensors adapted to provide a plurality of sensor readings, wherein each of the sensor readings is indicative of an operational parameter of a device;
• a calculation module adapted to calculate a covariance of the sensor reading or a correlation of divergence of at least two of the sensor readings;
• an analysis module configured to assign a confidence value to the sensor reading or to determine a dynamic consistency of the sensor reading;
• and
• a fusion module configured to determine a reliable sensor reading based on at least a weighting of the sensor reading based on the confidence value assigned to the sensor reading or the dynamic consistency of the sensor reading.

A computer readable medium, comprising:

• code adapted to analyze consistency of a plurality of sensor readings, wherein each sensor reading is indicative of an operational parameter of a device;
• code adapted to assign a confidence value to each of the sensor readings, wherein the confidence value is indicative of a signal stability of a sensor that provided the sensor reading;
• code adapted to weight each sensor reading based on the confidence value assigned to the sensor reading to determine an acceptance or a rejection of the sensor reading;
• and
• code adapted to fuse the sensor readings that are accepted to obtain a final sensor reading, wherein the final sensor reading provides a reliable indication of the operational parameter.
