Abstract:
A control device of a four-wheel-drive vehicle having an electronic control coupling changing a transmission torque, and a connecting/disconnecting mechanism connecting/disconnecting an input to the input-side rotating member of the coupling, comprising: a storage portion storing a relationship between the drive current to the coupling and the transmission torque of the coupling; a control portion controlling the drive current based on the relationship; and a learning portion performing correction for the relationship through learning by applying a braking torque to the input-side rotating member by an electromagnetic actuator. The learning portion performs the correction for the relationship by using the drive current supplied to the coupling and the braking torque at the time of determination that the transmission torque is balanced with the braking torque based on rotational speeds of the input-side rotating member and the output-side rotating member while the rotational speed of the input-side rotating member is increased.

Claim (Index 6):
The control device of a four-wheel-drive vehicle according to  claim 5 , wherein\n the four-wheel-drive vehicle includes a first connecting/disconnecting mechanism connecting/disconnecting a power transmission path between the drive power source and the propeller shaft, and wherein the first connecting/disconnecting mechanism disconnects the power transmission path between the drive power source and the propeller shaft before applying the braking torque to the input-side rotating member by the electromagnetic actuator.
