Popis: | In this paper, the hydraulic cooling system of an automotive hybrid dual-clutch transmission is modeled for the purpose of observer-based fault-detection. The considered fault case is a blocking of a functionally relevant switching valve resulting in a critical lack of cooling capacity during the clutch actuation. Three different model-based fault detection schemes are presented, namely an augmented extended Kalman filter with a position-based fault detection strategy and two dual-model observers with a position-based and a gating-based fault detection strategy, respectively. The fault detection schemes are validated using data from a test bench showing promising results. |
