Summary: | The invention relates to the technical field of vehicles, and particularly discloses a gear shifting control method and device and an engineering machine. The gear shifting control method comprises the following steps: after determining that gear shifting is needed, adjusting a clutch of a target gear to be in a semi-combined state from a separation state, and meanwhile adjusting a clutch of a current gear to be in the semi-combined state from a combined state; then judging whether the change rate a of the difference value of the input rotating speed and the output rotating speed of the clutch is within the set range or not, if so, adjusting the clutch of the target gear to be in the combined state from the semi-combined state, and meanwhile adjusting the clutch of the current gear to be in the separated state from the semi-combined state; and if the change rate a exceeds the set range, decreasing the control current I11 of the clutch of the target gear, increasing the control current I12 of the clutch of the |
