PROBLEM TO BE SOLVED: To provide a clutch control unit of a hybrid vehicle making it possible to highly precisely control a clutch torque despite a temperature change in a working fluid with a disengagement sustained state of a clutch device held intact.SOLUTION: Included are a clutch temperature arithmetic block 51 that computes a clutch temperature TmC on the basis of the number of rotations Ne of an engine output shaft, the number of rotations Ni of a transmission input shaft, and an engine torque Te, a working fluid temperature arithmetic block 52 that computes a working fluid temperature on the basis of the clutch temperature TmC and a reference distance to a slave cylinder 47, a reference temperature memory block 53 that stores as a reference temperature the working fluid temperature TmO1 detected when an idle port 70 is closed, a corrective advance/withdrawal movement quantity arithmetic block 54 that computes a corrective advance/withdrawal movement quantity &Dgr;Lam of an output rod 64, which cancels out a variable advance/withdrawal movement quantity &Dgr;Lfr of an output member 47a which is moved to be advanced or withdrawn along with a change in a volume derived from a difference between the working fluid temperature TmO2 and reference temperature, and a corrective advance/withdrawal movement quantity drive unit 57. |
