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.
Claims11
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, and
- correcting 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.
