変速装置。 An automatic transmission for vehicles equipped with a clutch mechanism that connects and disconnects the clutch by supplying and exhausting air to the clutch booster under automatic control by the driver's clutch pedal operation or by a control unit of a control valve installed in the air piping to the clutch booster. a clutch position detection means for detecting the engagement/disengagement state of the clutch from the amount of clutch stroke; and a clutch for detecting the presence or absence of pedal operation by the driver and inputting an ON signal to the control unit when the clutch pedal is sufficiently depressed. A pedal push position detection means, a clutch pedal free position detection means for inputting an ON signal to the control unit when the clutch pedal is not depressed or hardly depressed, and a gear position of the transmission is detected. and gear position detection means, and when the driver operates the clutch pedal while the transmission is in gear and the clutch is automatically disengaged, the control unit controls the control valve, The air is rapidly exhausted from the clutch booster within the ON signal generation area of the clutch pedal push position detection means, and the air is not exhausted from the clutch booster within the ON signal generation area of the clutch pedal free position detection means, and the clutch is In the OFF range of both the pedal free position detecting means and the clutch pedal push position detecting means, when the clutch stroke amount is on the clutch disengaged side than a predetermined value according to the detection signal of the clutch position detecting means, air is supplied from the clutch booster. An automatic transmission device for a vehicle, characterized in that air is rapidly exhausted and air is slowly exhausted from within a clutch booster when the clutch stroke amount is closer to the clutch than the predetermined value.
