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 1):
A control device of a four-wheel-drive vehicle having an electronic control coupling changing a transmission torque transmitted from an input-side rotating member to an output-side rotating member depending on a supplied drive current, and a connecting/disconnecting mechanism connecting/disconnecting an input of power to the input-side rotating member of the electronic control coupling through an operation of an electromagnetic actuator applying a braking torque to the input-side rotating member of the electronic control coupling, the control device comprising:\n a storage portion configured to store a first relationship between the drive current supplied to the electronic control coupling and the transmission torque of the electronic control coupling; a control portion configured to control the drive current supplied to the electronic control coupling based on the first relationship; and a learning portion configured to perform a correction for the first relationship through learning by applying the braking torque to the input-side rotating member by the electromagnetic actuator, wherein the learning portion performs the correction for the first relationship stored in the storage portion by using the drive current supplied to the electronic control coupling and the braking torque at the time of determination that the transmission torque is balanced with the braking torque based on a rotational speed of the input-side rotating member and a rotational speed of the output-side rotating member while the rotational speed of the input-side rotating member is increased by the control portion.
