A clutch control assembly includes a clutch switches over a connected and disengaged state between an engine and a driven member. A first hydraulic pressure generating member is provided for generating hydraulic pressure for switching between a connected and disengaged state of the clutch according to an operation of a vehicle driver. A second hydraulic pressure generating member, independent from the first hydraulic pressure generating member, is provided for automatically generating hydraulic pressure for switching between a connected and disengaged state of the clutch according to drive conditions of the vehicle. A first piston with one side facing the first hydraulic pressure chamber linked to the first hydraulic pressure generating member and a second piston with one side facing the second hydraulic pressure chamber linked to the second hydraulic pressure generating member independent from the first hydraulic pressure generating member are interlock so as to be linked to the clutch.
