AI Technical Summary
Technical Problem
During the control of the lock-up clutch, the problem of shift shock caused by overfilling or underfilling of oil was not effectively resolved.
Method used
The oil filling process of the lock-up clutch is detected and divided into three stages: the initial oil filling stage, the rapid oil filling stage, and the pressure maintenance stage. The oil filling status is determined by the difference between the input shaft speed and the speed acceleration filter value, and the oil filling time is dynamically adjusted to control the oil filling pressure.
Benefits of technology
It effectively solves the problem of shift shock caused by overfilling or underfilling of oil during lock-up clutch control, and achieves more stable oil filling control.

Abstract
本申请提供一种锁止离合器的控制方法、装置、存储介质及变速箱。该方法在检测到锁止离合器的充油过程已进入快速充油阶段后，若各时刻的输入轴转速对应的输入轴转速加速度原始值与相应的输入轴转速加速度滤波值的差值满足预设的充油自适应触发条件，则获取第二子阶段和第三子阶段内各时刻的输入轴转速以及相应的输入轴转速加速度滤波值；确定任一子阶段内各时刻的输入轴转速的波动程度，并基于输入轴转速的波动程度，确定该子阶段的充油状态；基于充油状态，对锁止离合器的充油时间进行动态调整。该方法解决了锁止离合器控制过程中因为过充油或充油不足导致换挡冲击等问题。
