Abstract: A method to determine, in real time, a use-life of a steering system includes tracking an attribute signal associated with the steering system. The method further includes, based on a determination that the attribute signal rises above an upper threshold and subsequently falls below a lower threshold, selecting a subset of categories based on a frequency content of the attribute signal. The method further includes selecting a category from the subset of categories based on a peak load occurring in sequence to the attribute signal via a secondary attribute signal. The method further includes incrementing a counter for the selected category. The method further includes computing the use-life based on a ratio of the counter for the selected category and a predetermined count for said selected category.
