Adaptive Control Strategy for Complex Starting Conditions of Vehicles with Dry Dual Clutch Transmission 2022-01-0284

For vehicles equipped with dry dual clutch transmission, due to the diversity of starting conditions, it is a nontrivial task for control strategy to meet the requirements of all kinds of complex starting conditions, which is easy to cause large starting shock and serious clutch wear. Therefore, it is proposed in this paper an adaptive control strategy for complex starting conditions by adjusting two clutches to participate in the starting process at the same time. On the basis of establishing the transmission system model and clutch model, the starting conditions are identified in terms of starting speed, road adhesion and driver's intention, in which the driver's intention is identified by fuzzy reasoning model. Based on the identification of starting conditions and considering the safety principle, it is selected the appropriate starting gear and clutch combination mode, and adjusted the combination speed of the two clutches to carry out an adaptive control strategy. The Simulink simulation model is built, and the typical working conditions are selected for experimental verification. The results show that the control strategy can effectively reduce the starting shock, prolong the service life of the clutch and adapt to more starting conditions.
