Abstract
A method and system for estimating the corrosion levels of a steering rack of a vehicle. Measurements of torsional force applied to the steering rack are taken with respect to the displacement of the steering rack from a neutral position and the moving velocity of the vehicle, and compared to the expected values corresponding to a non-corroded steering rack. The degree of difference between the measured and expected values may then be used to estimate the level of corrosion of the steering rack.
