Tuning parameter of kalman filter in a wheel inspection
First Claim
1. A method for tuning a parameter of a Kalman filter in a wheel inspection for a vehicle, comprising:
- associating wheel inspection data of said vehicles with locations of corresponding wheels in said vehicle;
evaluating a wheel stable score of said vehicle based on said wheel inspection data and said association, wherein said wheel stable score indicates reliability of said wheel inspection, the wheel stable score calculated according to a wheel diameter differential of left and right wheels coupled to a common axis; and
dynamically tuning a measurement error covariance (R) of said Kalman filter according to said evaluated wheel stable score.

Abstract
A method for tuning a parameter of a Kalman filter in a wheel inspection for a vehicle. The method includes: associating wheel inspection data of the vehicle with locations of wheels in the vehicle; evaluating a wheel stable score of the vehicle based on the wheel inspection data and the association, wherein the wheel stable score indicates reliability of the wheel inspection; and tuning measurement error covariance of the Kalman filter according to the evaluated wheel stable score. By using the method, the parameter of the Kalman filter can be dynamically tuned to enable the Kalman filter to filter more accurately to ensure the correct result of the wheel inspection. In addition, an apparatus for tuning a parameter of a Kalman filter and a wheel inspection system for a vehicle are disclosed.
