自動変速装置。 The clutch is engaged and disengaged by operating the clutch pedal by the driver or by operating the clutch actuator in response to commands from the control unit.
An automatic transmission for a vehicle in which a transmission actuator is actuated by a command from a control unit based on a designated shift signal from a shift lever to shift a transmission to a synchronized gear or a non-synchronized gear, Countershaft rotational speed detection means and mainshaft rotational speed detection means for detecting the rotational speed of the countershaft and mainshaft of the transmission, respectively, clutch engagement/disengagement detection means for detecting the engagement/disengagement state of the clutch, and designation of the shift lever. and gear position detection means for detecting the shift stage, and when the shift stage specified by the shift lever is a non-synchronized stage and the clutch is disengaged based on the signals from each of the detection means, the synchronization is performed by the transmission actuator. When the relative rotational difference between the detected countershaft rotational speed and the main shaft rotational speed is less than the integrated value, the shift to the synchronized gear is stopped and the shift to the specified non-synchronized gear is started. An automatic transmission device for a vehicle, characterized in that the automatic transmission device starts a shift.
