理をすることを特徴とした車両用自動変速装置。 A clutch actuator that operates a friction clutch connected to the engine intermittently, a gear shift unit that switches the gear train of a gear type transmission connected to the friction clutch, a gear change switch that issues a designated gear position command signal, and vehicle speed information. a clutch stroke sensor that outputs information on the stroke amount of the clutch; a clutch rotation speed sensor that outputs information on the rotation speed of the clutch plate of the clutch; and when the vehicle speed exceeds a set value, a start control is performed. In the automatic transmission system for a vehicle, the clutch stroke position is set to a braking half-clutch position where the engine rotation applies a braking force to the clutch plate, and the control means When the clutch is disengaged for upshifting, the clutch is first switched to neutral, and if the clutch rotational speed exceeds the engine rotational speed, the clutch is returned to the braking half-clutch position and the clutch is disengaged again. An automatic transmission device for a vehicle that is characterized by:
