본 발명은 사륜 구동 전동화 차량의 도그클러치 체결 방법에 관한 것으로, 상세하게는 구동 모드의 전환 시에 도그클러치에서 발생하는 충격 및 소음을 효과적으로 저감할 수 있는 사륜 구동 전동화 차량의 도그클러치 체결 방법에 관한 것이다.
A dog clutch engagement method of an electric four-wheel drive vehicle includes steps of: when dog clutch engagement is requested during driving, determining a target synchronization speed of the input gear to be a sum of an estimated speed and an offset speed of the output gear; operating a drive unit so that an input gear follows the target synchronization speed; when an actual speed of the input gear reaches the target synchronization speed, moving a sleeve to a meeting position at which the sleeve is in contact with the input gear; and when the actual speed of the input gear is synchronized with an actual speed of the output gear, transporting the sleeve to an engagement position at which the input gear and the output gear are coupled.
