Excessive temperatures tend to occur in dual clutch transmissions (DCTs) due to large amount of friction heat generated in the compact space, but seriously deteriorate shift quality and even reduce lifespans. In order to accurately obtain the DCT temperature in real-time, a four-parameter model is proposed to modify the previously studied static two-parameter model by introducing two dynamic coefficients. According to the deduction of energy balance equation based on a one-dimension assumption, the two dynamic coefficients are found to inherently change along with the friction heat and ambient temperature. Their changing rates constitute a four-parameter model. The new model is verified by dynamometer experiments, which show higher accuracy and better adaptability to working conditions than the static two-parameter model.
