Abstract

An inertia torque input into the continuously variable speed change mechanism from the subtransmission mechanism is estimated during the shift in the subtransmission mechanism. During the shift in the subtransmission mechanism, a required oil pressure, which is an oil pressure required to maintain a contact frictional force between the respective pulleys and the wrapped member, is calculated on the basis of an input torque into the continuously variable speed change mechanism and the inertia torque.
