ABSTRACT:
A torque control arrangement for a four-wheel-drive vehicle comprises a fluid torque transmitting device disposed in a front or rear torque transmitting path and operative to vary torque transmitted therethrough in response to a difference between input speed and output speed thereof, a clutch device provided in series to the fluid torque transmitting device, front and rear speed reduction devices for determining a final drive ratio in the front torque transmitting path and a final drive ratio in the rear torque transmitting path, respectively, first and second speed sensors for detecting the input speed and the output speed of the fluid torque transmitting device, respectively, and a control unit operative to disengage the clutch device when a speed difference obtained by substracting the output speed of said fluid torque transmitting device from the input speed of said fluid torque transmitting device is reduced to a range of positive values, the upper limit of which is not greater than a predetermined small value close to zero.
