Example Embodiment
[0033] figure 1 It is a flowchart of the steps of a shifting method of an AMT automatic transmission according to an embodiment of the present invention. Such as figure 1 As shown, in this embodiment, the gear shifting method of the present invention includes the following steps:
[0034] Step S101: the vehicle is ignited and starts to travel.
[0035] Step S102: During the running of the vehicle, the AMT automatic transmission is in any forward gear, and it is judged whether it is necessary to shift to other forward gears according to the vehicle driving state parameters and the control signal. If the gear needs to be shifted, proceed to step 103 , Otherwise repeat step S102.
[0036] Step S103: Determine the target gear to be shifted.
[0037] Step S104: Calculate the desired engine target speed Engine_TargetSPD when the target gear clutch is fully engaged according to the current vehicle speed and the gear ratio of the target gear.
[0038] Step S105: Determine whether the engine...
