Abstract:
1. An output shaft locking device in a multi-clutch transmission in which a plurality of rotational mechanisms, each of which is formed by arranging a clutch and a shifting mechanism in series, is provided in parallel between a rotational power input shaft and a rotational power output shaft, comprising: a locking control device which locks the rotational power output shaft by engaging a shifting gear in each of the shifting mechanisms of at least two of the rotational mechanisms and engaging the clutches of the rotational mechanisms having the shifting gear engaged by the locking control device; a rotational power output shaft lock determining device which determines whether the rotational power output shaft can be locked, wherein the locking control device locks the rotational power output shaft when it is determined by the rotational power output shaft lock determining device that the rotational power output shaft can be locked, wherein the multi-clutch transmission is a transmission in a vehicle, which transmits rotational power from a drive source to a wheel of the vehicle, and the rotational power output shaft lock determining device determines that the rotational power output shaft can be locked when predetermined conditions are satisfied, the predetermined conditions including a condition that the rotational power from the drive source is not being transmitted to the rotational power input shaft and a condition that the vehicle is not running.
