Embodiment Construction
[0040] The present invention is described in detail below in conjunction with accompanying drawing:
[0041] figure 1 It is a flow chart of an adaptive control method for engaging clutch torque during the shifting process of an automatic transmission according to an embodiment of the present invention. Such asfigure 1 As shown, the automatic transmission shift clutch torque adaptive control method provided in this embodiment includes the following steps:
[0042] Step 1: Obtain the average change rate of the actual input shaft speed in the first stage of the automatic transmission shifting process. First, calculate the change rate of the input shaft speed in each step according to the input shaft speed of each step, and then calculate the first step in the shifting process of the automatic transmission. The average change rate of the actual input shaft speed in the stage, that is, the average change rate of the actual input shaft speed in the first stage of the automatic tran...
