Abstract
A differential used for distributing input torque, is provided with: a casing to receive the input torque; a differential gear set supported by the casing for differentially distribute the input torque to first and second side gears; a clutch interposed between the casing and the first side gear to limit differential motion between the first side gear and the second side gear; an actuator to exert a pressure force on the clutch to control the differential motion; and an electronic control unit configured to calculate a locking rate from a selected differential torque ratio, calculate a requesting torque from a product as a result of multiplying the input torque by the locking rate, and control an electric power to be input to the actuator on the basis of the requesting torque.
