Abstract
The control system comprises: an operating state changing mechanism for an operating state of the prime mover in response to a satisfaction of learning execution condition of the clamping pressure; a torque change suppressing mechanism for suppressing a change in a torque resulting from the change in the operating state of the prime mover; and a clamping pressure learning device 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 mechanism.
