Abstract
An automatic shift device for an automated transmission for a vehicle includes a rotation shaft, a clutch ring, a clutch hub, a sleeve, a dog clutch portion, a shaft moving apparatus, and a control portion. The control portion includes a push force reduction control portion performing a push force reduction control reducing a push force of the sleeve that the shaft moving apparatus applies on the clutch rear teeth in response to a back and forth movement of the sleeve after the sleeve reaches an end surface of the clutch rear tooth. The control portion includes a retry control portion performing a retry control that re-applies the push force of the sleeve in response to a predetermined retry condition after the push force reduction control is performed.
