    Abstract: An autonomous vehicle including a Kalman filter error recovery system is disclosed. The Kalman filter error recovery system includes at least one processor and at least one memory storing instructions, which, when executed by the at least one processor, cause the Kalman filter error recovery system to perform operations including increasing eigenvalues of a covariance matrix to adjust probability distribution of a state vector error due to unmodelled process noise in measurements from one or more position sensors, and returning the state covariance to a diagonal state to perform a dynamic covariance reset.
