Torsional mode tire wear state estimation system and method |
摘要 |
A tire wear state estimation system includes a tire pressure measuring device affixed to a vehicle tire for measuring tire inflation pressure and generating tire inflation pressure data; tire torsional mode measuring means for measuring tire torsional mode frequency and generating tire torsional mode frequency data; and tire identification means for generating tire-specific torsional mode coefficients using tire-specific identification data. A tire wear estimation is made based upon the tire inflation pressure data, the torsional mode frequency data, and the tire identification derived torsional mode coefficients. |

1. A tire wear state estimation system comprising:
at least one tire supporting a vehicle; tire pressure measuring means affixed to the one tire for measuring tire inflation pressure and generating tire inflation pressure data; tire torsional mode measuring means for measuring tire torsional mode frequency and generating tire torsional mode frequency data; tire identification means mounted to the one tire operably utilized in generating tire-specific frequency mode coefficients using tire-specific identification data; and tire wear estimation means for calculating an estimation of a tire wear state based upon the tire inflation pressure data and a spectral analysis of the torsional mode frequency data employing the tire-specific frequency mode coefficients. |
