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.

Force-based corrosion detection for vehicle steering rack

A system and method for detecting corrosion in a steering rack of a vehicle based upon the performance of the steering rack in comparison to reference data collected for a non-corroded steering rack. Corrosion may be detected based upon analysis of performance data with respect to steering joggle or a data transform. Performance data may comprise displacement of the steering rack with respect to a neutral position, or the force applied to the components of the steering system.
