Abstract:
–For a reliable prognosis of clutch wear, the knowledge of friction lining temperature is crucial. Due to the lack of temperature sensors within the clutch, a reliable model is required to estimate the friction lining temperature. In this contribution, a thermal model for dry clutch temperature estimation is presented. The thermal system is described by a lumped-element model, which is capable of estimating the friction lining temperature based on the friction energy. Furthermore, external temperature influences ofcombustion engine and ambient air, as well as nonlinear effects,are considered. Results of modelidentification and validation for an automated manual transmission (AMT) on a test bench are shown in this article.
