Abstract
An apparatus for tuning a parameter of a Kalman filter in a wheel inspection for a vehicle is disclosed. The apparatus includes an association module that associates wheel inspection data of the vehicle with locations of corresponding wheels in the vehicle; an evaluation module that evaluates a wheel stable score of the vehicle based on the wheel inspection data and the association, where the wheel stable score indicates reliability of the wheel inspection; and a parameter tuning module that tunes a measurement error covariance of the Kalman filter according to the evaluated wheel stable score.
Claims11
An apparatus for tuning a parameter of a Kalman filter in a wheel inspection for a vehicle, comprising:
- an association module that associates wheel inspection data of said vehicle with locations of corresponding wheels in said vehicle;
- an evaluation module that evaluates a wheel stable score of said vehicle based on said wheel inspection data and said association, wherein said wheel stable score indicates reliability of the wheel inspection, the wheel stable score calculated according to a wheel diameter differential of left and right wheels coupled to a common axis;
- and
- a parameter tuning module that dynamically tunes a measurement error covariance (R) of said Kalman filter according to said evaluated wheel stable score.
