In another embodiment, the shift force control method further employs a target differential rate of change algorithm in determining the shift force for the synchronous phase of the transmission shifting process. In yet another embodiment, the shift force control method further employs a transmission shifting power source component control algorithm in determining the shift force for the synchronous phase of the transmission shifting process. The above algorithm may be used in combination with a physical model or as a separate model.
According to an embodiment of the present application, a shift force control method includes the steps of:
s1, acquiring a target speed difference of the rotating speed of the input shaft of the gearbox and an actual speed difference of the rotating speed of the input shaft of the gearbox and calculating a target change rate of the rotating speed difference of the input shaft of the gearbox;

and S3, executing the gear shifting synchronization process according to the values of the target control parameters of the plurality of gear shifting power source components.
Fig. 1 schematically shows the sequential relationship of steps S1, S2, and S3. For example, step S1 takes as inputs the transmission input shaft speed difference target 101 and the transmission input shaft speed difference actual 102, and the transmission input shaft speed difference target rate of change 111 as the output of step S1.
