摘要

A transmission control system includes torque distribution control unit 50, differential (20) and clutch (27). The clutch (27) acts between output members of the differential (20) whereby torque is transmitted to front and rear wheels at a distribution ratio determined by the torque transmitted through the clutch (27). The control unit (50) operates the clutch (27) so as to distribute the torque at a ratio in accordance with slipping of either of front wheels or rear wheels so as to reduce the torque applied to the slipping wheels. The control unit also responds to four wheel slip to depower the engine by closing the throttle (15).
