変速装置。 Signals from engine rotational speed detection means, transmission input shaft rotational speed detection means, transmission output shaft rotational speed detection means, clutch pedal depression detection means, clutch stroke detection means, transmission shift position detection means and shift lever position detection means Based on the above, three values are obtained by converting the engine rotation speed, transmission input shaft rotation speed, and transmission output shaft rotation speed into reference rotation speed when the clutch is engaged, the transmission is shifted, and the transmission is not shifting. For a vehicle, the vehicle is characterized by being provided with a determining means for determining the truth or falsity of the three rotational speeds by comparing the magnitudes of two of the sums, and determining whether the three rotational speed detection means are malfunctioning. Automatic transmission.
