いことを特徴とする車両用自動変速装置。 A clutch actuator that operates a clutch connected to the engine intermittently, a gear type transmission connected to the clutch, an engine rotation sensor that outputs engine rotation speed information, and an accelerator sensor that outputs accelerator opening information. , a vehicle speed sensor that outputs vehicle speed information, a clutch rotation sensor that outputs rotation speed information of the output shaft of the clutch, a clutch stroke sensor that outputs stroke information of the clutch, and the engine rotation speed information and clutch rotation speed. In the automatic transmission device for a vehicle, the control means determines the synchronization between the two based on the information and enters the clutch engagement process, and the control means controls the accelerator opening when the synchronization occurs and the gear is in reverse gear. It is characterized by outputting a pseudo signal voltage by adding a voltage equivalent to the change in accelerator opening to the same voltage value, and not fully engaging the clutch and engine until the clutch rotation speed exceeds a specified value. An automatic transmission device for vehicles.
