Abstract
A method according to an exemplary aspect of the present disclosure includes, among other things, arbitrating velocity signals derived from information from a first sensor and a second sensor, estimating a ratio between an actual tire radius and an expected tire radius, and generating a fused velocity estimate based on an arbitrated signal calculated during the arbitrating step and an estimated ratio calculated during the estimating step.
