<p>PROBLEM TO BE SOLVED: To provide a vehicular transmission device capable of broadening an operation region in a travel mode of high power transmission efficiency, and capable of improving fuel consumption performance of a vehicle.SOLUTION: In a vehicular transmission device A, as a travel mode of a vehicle set by switching of clutches C1, C2, selection can be made between a first travel mode which utilizes only a continuously variable transmission mechanism 4, and a second travel mode which utilizes a stepped transmission mechanism 5 with or without the continuously variable transmission mechanism 4 being used in combination. Under the condition in which the second travel mode is set further on a high speed area side of vehicle speed than the first travel mode, a mode switching change gear ratioγin which the change from the first travel mode to the second travel mode is performed is further on a low side than a change gear ratioγof the stepped transmission mechanism 5.</p> |
