[0052] Example
[0053] See figure 1 , figure 1 This is a flow chart of a method for controlling shifting of a hydraulic automatic transmission according to an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0054] Step S101: detecting the shift signal of the automatic transmission;
[0055] Specifically, the shift signal of the automatic transmission from the automatic transmission cooperative control system is detected.
[0056] Step S102: When the shift signal is detected, compare the current shifting condition with the preset different shifting conditions to obtain a preset shifting condition that matches the current shifting condition ;
[0057] Specifically, the preset different shifting conditions include: a powered upshift operating condition, a powered downshift operating condition, an unpowered upshift operating condition, and an unpowered downshift operating condition. Powered upshift operating conditions refer to the operating condit...
