Abstract

A differential is provided with: a torque receiving casing; a differential gear set having first and second side gears to differentially distribute torque to the first and second side gears; a clutch interposed between the casing and the first side gear and configured to exert a frictional braking force on the first side gear against the casing to limit a differential motion between the first side gear and the second side gear; an actuator configured to apply a pressing force to the clutch to control the differential motion; and an electronic control unit configured to calculate a demand torque value from the input torque, compare the wheel load with a threshold value to determine a correction value, make a correction in the demand torque value by the correction value to obtain a demand value, and control an electric power supplied to the actuator in response to the demand value.
