Claim 9:
10. A driver assistance system comprising:
a plurality of sensors, each sensor generating a data stream; and
a processor that executes instructions stored in memory, wherein execution of the instructions by the processor:
monitors a plurality of sensors of the driver assistance system in real-time, each sensor generating a data stream;
identifies a sensor of the plurality of sensors having an anomalous data stream;
calculates a primary localization from the respective data streams, including the anomalous data stream, from the plurality of sensors, the primary localization calculation including the anomalous data stream;
calculates a backup localization calculation from a subset of the respective data streams not including the anomalous data stream;
determines an error estimate based on a difference between the primary localization and the backup localization; and
executes an action when the error estimate of the backup localization exceeds a threshold.
