This invention discloses a method for self-learning the clutch of an AMT (Automated Manual Transmission) in commercial vehicles, specifically including the following steps: Step 1: Determine whether the current vehicle meets the self-learning conditions; if so, proceed to Step 2; Step 2: Clutch self-learning: After activating clutch self-learning, the clutch will perform two rounds of disengagement and engagement; Step 3: After the clutch performs two disengagement and engagement actions, the learned parameters are stored in the TCU (Tracking Control Unit), completing one clutch self-learning cycle; Step 4: Repeat the above process to complete multiple clutch self-learning cycles. The method of this invention defines the complete disengagement point and the first, second, and third contact points by using the input shaft speed as a threshold, resulting in higher recognition accuracy and a simpler and more efficient TCU judgment and calculation logic.
