This study aims to investigate the braking process in automotive Anti-lock Braking Systems, with a particular focus on relationship between brake disk temperature variation and pyroelectric energy recovery. We developed detailed numerical simulation model that considers wheel dynamics, thermal behavior of disk, generation mechanism materials. The is based Pacejka “Magic Formula” incorporates nonlinear factors slip ratio, ground force, variation, voltage generation, simulating at different vehicle speeds. Through analysis, we demonstrate dynamic changes under various speeds, explore impact speed recovery efficiency. results show as increases from 25 35 m/s, amount recovered 0.0021 0.0061 J, while rises 181.56 359.58 °C. indicates higher rapid increase enhances conversion efficiency By introducing parameter adjustments, our more accurately describes characteristics during process, particularly high speeds extreme conditions. findings this suggest systems have significant potential field recovery, notably improving increases. These insights provide strong theoretical support experimental evidence for future design highlight direction system optimization, such further improvement material properties devices.
