The invention relates to an electrically-control type differential lock control mechanism, and belongs to the technical field of electrically-control type automobile drive axles. The electrically-control type differential lock control mechanism comprises a reducer shell. A shifting fork shaft is arranged in the reducer shell and sleeved with a shifting fork and a return spring. The shifting fork is connected with a shift sleeve in a limiting mode. The shift sleeve is arranged on a main shaft in a sleeving mode. An axial limiting sleeve on the main shaft is provided with a drive gear capable of being meshed with the shift sleeve. An electric control mechanism is further arranged in the reducer shell. The output end of the electric control mechanism is connected with a push rod mechanism capable of linearly moving. The push rod mechanism and the shifting fork shaft are coaxially arranged. The push rod mechanism makes axial contact with the shifting fork shaft in a connected mode. The invention further discloses an electrically-control differential lock control method. By means of the electronically-control differential lock control mechanism and method, locking and separation of a differential lock can be achieved under the conditions that no gas source exists when an automobile is motionless and after parking and flameout are conducted, gear shifting is convenient to conduct, and the locking requirement required in the hill-holding brake process is met.
