<p>PROBLEM TO BE SOLVED: To provide a shaft power transfer controller capable of obtaining an optimum torque transmission in accordance with the change of the oil temperature retaining the function of a clutch mechanism. SOLUTION: In the processing of the surface temperature Tcoup of a shaft power transfer device 10, the temperature Tcoil of electromagnetic coil 13a of an electromagnet 13 constituting a pilot clutch mechanism 10d is computed. The exothermic quantity of the clutch section Qcoup (=ΔN.T3) that the exothermic quantity of the main clutch mechanism 10c and the exothermic quantity of the pilot clutch mechanism 10d are summed up is computed and further, the exothermic quantity (exothermic quantity of coil part), Qcoil (=V.I), of the electromagnetic coil 13a is computed, then the surface temperature Tcoup is obtained by computation from these values (Tcoil, Qcoup, Qcoil), etc.</p> |
