摘要： A frictional engaging device and frictional engagement control method, wherein with attention paid to the phenomenon of the frictional coefficient of the friction surfaces of a friction engagement device being changed when an electric field is applied to the friction surfaces, this phenomenon is utilized to control the transmittal force. Under the action of a pushing force, friction engagement members are brought into direct contact with each other for frictional engagement. When an electric field is applied between the frictional engagement members, the frictional coefficient of the friction surfaces changes, which means that the transmittal force can be changed. An example of the frictional engagement device is a clutch device (10). A friction member (20) made of insulation material is attached to an input disk (16) and engages an output disk (22). The friction surfaces are lubricated. A control device (30) controls a voltage applying device (28) and applies a voltage to an electrode (26) to provide a desired transmittal force.
