Claims (1)

[Scope of utility model registration request] a friction clutch connected to an engine, a clutch actuator for operating the friction clutch, and a gear transmission connected to the friction clutch;
a gear position sensor for detecting the gear position of the gear type transmission; a clutch rotation speed sensor for detecting a rotary plate of a clutch plate of the friction clutch attached to the input shaft of the gear type transmission; With the engine operating at a constant rotational speed in neutral, the clutch actuator is operated to gradually operate the friction clutch in the direction of connection and disconnection, and the rotational speed of the clutch plate is detected by the clutch rotational speed sensor. After a certain value is obtained by connecting the friction clutch, the clutch stroke amount is gradually reduced and the rotation speed of the clutch plate does not become zero even by moving the friction clutch in the disconnecting direction. An automatic transmission device for a vehicle, comprising: a control unit that determines a clutch stroke as a position just before a half-clutch state.
