A dog clutch control apparatus for an automated transmission includes a rotary shaft (24), plural dog clutch mechanisms (30, 32, 34, 36, 38, 40, 44, 46), each of the dog clutch mechanisms including a clutch ring (30, 32, 44, 46), a clutch hub (34) arranged next to the clutch ring, a sleeve (36) fitted with the clutch hub, a dog clutch portion (30a, 32a) which is provided at the clutch ring and selectively meshes with a spline (36a) formed at the sleeve, an axial driving device (40) for moving the sleeve, the dog clutch control apparatus includes a disengagement detecting portion (38) for detecting disengagement before the sleeve reaches a neutral position and a control apparatus (10) for controlling operation of the axial driving device, wherein in a case where the disengagement is detected at a time of shifting operation, the control apparatus starts a shift-related control.
