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 3):
The control device of a four-wheel-drive vehicle according to  claim 1 , wherein\n the electromagnetic actuator changes the braking torque applied to the input-side rotating member according to a first drive current supplied thereto, and wherein the control device comprises a first storage portion configured to store a second relationship between the first drive current supplied to the electromagnetic actuator and the braking torque, a first control portion configured to control the first drive current supplied to the electromagnetic actuator based on the second relationship, and a first learning portion configured to perform a correction for the second relationship through learning.
