The shift speed control method for the AMT gearbox includes the following steps: When the AMT gearbox shifts and adjusts speed, the motor executes a speed response mode, calculates the real-time speed difference at the sliding sleeve end, and determines whether the real-time speed difference at the sliding sleeve end is within the speed difference setting range. If yes, the speed adjustment is considered complete; otherwise, the speed adjustment is considered a failure, and the number of speed adjustment failures is accumulated. It is then determined whether the accumulated number of speed adjustment failures exceeds a failure limit. If so, the initial value of the speed difference setting range is adjusted based on the accumulated number of speed adjustment failures, and the adjusted speed difference setting range is the adjusted value of the speed difference setting range. If the adjusted value of the speed difference setting range exceeds the speed difference limit, the motor's speed response mode is switched to a torque response mode. This shift speed control method for the AMT gearbox improves the success rate of shift speed adjustment.
