In the downhill braking process, the high temperature of the service brake of heavy-duty trucks can lead to braking failure. To solve this problem, a brake heating model for heavy-duty trucks equipped with auxiliary brake systems is investigated. On the basis of coasting test, engine braking test, exhaust braking test, and eddy current retarder braking test, the model is established according to vehicle dynamics theory, energy conversion principle, and energy dissipation principle. Road tests are conducted to verify the accuracy of the model. Results demonstrate that the model accurately reflects the heating characteristics of the brake. Using this model to predict the brake temperature in different combined brake conditions is important to prevent traffic accidents caused by heat fading.
