[0047] The technical solutions of the present invention will be described in detail by the following examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be construed as limitations on the technical solutions of the present invention.
[0048] A wet dual-clutch automatic transmission micro-slip control method, such as figure 1 shown, including initialization control, torque drop control, torque rise control and micro-slip control.
[0049] Before the transmission is controlled, it is first judged whether the transmission meets the micro-slip control conditions. The micro-slip control conditions include that the transmission is not creeping, not starting, not shifting, and the clutch is not Open and not in failure mode.
[0050] After judging, if it matches, then proceed to the initialization control stage.
[0051] Under the initial control condition, it is judged whet...
