Abstract
A transmission torque estimation unit estimates a torque transmittable between an outer rotary member and an inner rotary member with respect to a control signal based on: a first model obtained by modeling an equation of motion of the outer rotary member in a rotation direction; a second model obtained by modeling an equation of motion, in the rotation direction, of a support cam member and an inner pilot clutch disc as one unit; a third model obtained by modeling an equation of motion of the outer main clutch discs in the rotation direction; a fourth model obtained by modeling an equation of motion of the inner rotary member in the rotation direction; and a fifth model containing a viscoelastic model and obtained by modeling an equation of motion, in an axial direction, of the inner main clutch disc and the movable cam member as one unit.
