SYSTEM AND METHOD FOR MONITORING VEHICLE CONDITIONS AFFECTING TIRES

摘要

A system and method for monitoring tread wear, shock absorber performanc e, balance condition of a vehicle tire, and/or rotation speed of a vehicle whee l, use a sensor to provide acceleration signals. To monitor tread wear, acceleration signals from the sensor determine at least one resonance frequency of at least one of the radial and lateral acceleration of the tire and compares it to at least one stored resonance frequency To monitor shock absorber performance, the amplitude of the Fourier component o f the radial acceleration is compared to a stored amplitude value. To monitor a balance condition of a vehicle tire, the sensor provides acceleration signals measur ed over a specified time duration to determine an amplitude of the Fourier component o f the radial acceleration that is compared to a stored amplitude specification balance condition of the tire.
