AI Technical Summary
Existing technologies struggle to effectively quantify the aging of tires under different operating and environmental conditions, making it difficult to compare and predict tire lifespan, especially considering differences across different geographical regions and seasons.
By employing the Arrhenius oxidation reaction rate equation combined with a data acquisition system, the aging unit (AU) is calculated and normalized by integrating the internal air temperature and ambient temperature to generate an aging index (AI or ΔAI) to quantify the degree of tire aging. This is then monitored and predicted in real time through computing equipment and servers.
It enables the quantification and comparison of tire aging under different conditions, predicts tire life and wear status, supports timely tire replacement and maintenance, and improves vehicle safety and efficiency.
