To precisely and finely control a hydraulic pressure for actuating a hydraulic clutch by correctly calculating a thrust force applied to a piston due to a centrifugal force acting on a working oil, in a hydraulic clutch controller in which the thrust force applied to the piston due to the centrifugal force acting on the working oil inside a hydraulic chamber is calculated, based on a clutch revolution speed and a specific gravity of the working oil, and besides an action of a hydraulic control means is controlled by a control unit so that a hydraulic pressure exerting hydraulic pressure force so corrected as to remove a calculated amount of thrust force is allowed to work in the hydraulic chamber of the hydraulic clutch.
A control unit 104 calculates the thrust force applied to the piston based on the specific gravity of the working oil determined depending on the detected value by a temperature detecting means 106 for detecting an index representative of the temperature of the working oil.
