<p>PROBLEM TO BE SOLVED: To provide a control device for a transmission, which can prevent racing of an engine at shifting time. SOLUTION: A transmission is provided with a first shift stage connecting a brake 10 and disconnecting a clutch 30 and a second shift stage connecting the clutch 30, wherein an input member to which a rotary driving force is inputted is connected to one gear element of a planetary gear set having three gear elements, an output member is connected to another one gear element of the planetary gear set, a rotary member is connected to the remained one gear element of the planetary gear set through a one-way clutch, a brake 10 connects/disconnects the rotary member to/from a fixing member, a clutch 30 connects/disconnects the input member and the output member mutually together/from each other. In this transmission, a shift estimation means 56 estimating a shift between the first/second shift stages is provided, and brake control means 58, 59 controlling the brake 10 make it operate before operation of the clutch 30 when the shift is estimated by the shift estimation means 56.</p> |
