1. A continuous recalibration method for a vehicle including a wheel speed sensor, comprising the steps of:
- receiving signals from a satellite,deriving a reference value of a vehicle motion parameter from said satellite signals,receiving signals from said wheel speed sensor,deriving a measured value of said vehicle motion parameter from said wheel speed sensor signals, andcorrecting said wheel speed sensor signals so as to bring the measured value of said vehicle motion parameter into agreement with the reference value of said vehicle motion parameter.

Abstract
A system for establishing a vehicle parameter including collecting signals from a satellite and deriving a reference vehicle parameter from the satellite signals. Signals from a vehicle sensor are also collected and an estimated vehicle parameter is derived therefrom. Once the satellite signals and the estimated vehicle parameter signals are collected, parameters for a correction algorithm are generated and thereafter, the correction algorithm is applied to vehicle sensor signals to generate a corrected vehicle parameter or to generate a vehicle tire status parameter.
