Abstract

Accurate real-time estimation of disc brake temperature is crucial for automotive safety. This study proposes a novel lumped-parameter thermal model for real-time estimation of disc brake temperature, specifically designed for low-cost embedded controllers. The model integrates heat transfer principles with experimentally identified parameters to balance accuracy and computational efficiency. A first-order inertia model captures the dynamic thermal interaction between the brake disc and pads. Experimental validation demonstrates temperature estimation errors less than 3.5°C
