Provided are: malfunction-detection units (S100, S102) for detecting malfunctions in a first input-shaft rotation sensor (91) and a second input-shaft rotation sensor (92), to allow calculation, when one of two rotation sensors fails, of the number of rotations of an input shaft on the failed sensor side using the output of the other, functioning, rotation sensor; a transmission-control device (23) for, when a malfunction is detected by a malfunction-detection unit in either the first input-shaft rotation sensor or the second input-shaft rotation sensor, controlling the shift mechanism if the vehicle is stopped and activating one of the odd-numbered gears and one of the even-numbered gears simultaneously, allowing driving of the vehicle with only one odd-numbered gear and one even-numbered gear without changing gears; and a rotation-calculation unit (S110) for calculating, in the state where one odd-numbered gear and one even-numbered gear are simultaneously activated, the number of rotations of the first input shaft or the second input shaft on the side corresponding to the input-shaft rotation sensor which was detected as malfunctioning, on the basis of the detected output of the functioning input-shaft rotation sensor. |
