Abstract:
1. A control system for a continuously variable transmission of a vehicle, in which a clamping pressure of rotary members to clamp a transmission member is learned and set in every operating state of a prime mover connected to an input side of the continuously variable transmission having the rotary members and the transmission member, comprising: an operating state changing means for changing an operating state of the prime mover in response to a satisfaction of learning execution condition of the clamping pressure; a torque change suppressing means for suppressing a change in a torque resulting from the change in the operating state of the prime mover; and a clamping pressure learning means for learning the clamping pressure in the operating state of the prime mover after the change, while the operating state of the prime mover is being changed and the change in the torque resulting from the change in the operating state of the prime mover is being suppressed by the torque change suppressing means.
