Abstract
When reception of engine rotating speed information from an engine control unit is failed, the control unit puts gear positions belonging to a second gear position group in a non-operable and connected state, and then puts a second clutch into a engaged state to convert a rotating speed of a second input shaft detected by a second rotational sensor into a rotating speed of an engine output shaft. The control unit controls so as to fasten a first clutch based on the converted rotating speed of the engine output shaft, thereby enabling a star of a vehicle.
