    摘要: A control device of a four-wheel-drive vehicle having an electronic control coupling (92L, 92R) changing a transmission torque, and a connecting/disconnecting mechanism (32) connecting/disconnecting an input to the input-side rotating member of the coupling, the control device (78) comprises: a storage portion (180a, 182a) storing a relationship between the drive current to the coupling and the transmission torque of the coupling; a control portion (180, 182) controlling the drive current based on the relationship; and a learning portion (180b, 182b) performing correction for the relationship through learning by applying a braking torque to the input-side rotating member by an electromagnetic actuator (128). 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.

    摘要: To achieve a balance between ensuring four-wheel drive performance, on the one hand, and energy conservation performance, on the other, when there is a request to engage the dog clutch. The system for transmitting drive force to the left and right rear wheels (19, 20) comprises a dog clutch (8) and an electronically controlled coupling (16); a 4WD control unit (34) is provided, which carries out the control of starting the engagement of the dog clutch (8), which is in a disengaged state, after placing the dog clutch (8) in a rotationally synchronized state by engaging the electronically controlled coupling (16) and increasing the output rotation thereof, when there is a request to engage the dog clutch (8). In this clutch control device for a four-wheel drive vehicle, the 4WD control unit (34) sets the engagement start timing of the electronically controlled coupling (16) when a transition is made to the "connected, four-wheel drive mode" to an earlier timing compared to when a transition is made to the "standby two-wheel drive mode," when there is a request to engage the dog clutch (8) while in a state in which the "disconnected, two-wheel drive mode" is selected.

    摘要: An electronic control unit (9) of a four wheel drive vehicle (100)controls a transmission torque of a driving force transmission apparatus (160, 7, 8) provided between a rear differential (150) and a left rear wheel (105L). The electronic control unit (9) includes a first computation unit (921) that computes a command torque to be transmitted to the left rear wheel (105L) by the driving force transmission apparatus (160, 7, 8), based on a traveling state of the four wheel drive vehicle; and a second computation unit (922) that corrects the command torque computed by the first computation unit (921), if a difference between rotation speeds of a pair of side gears (53L, 53R) of the rear differential (150) is larger than or equal to a predetermined value.

    摘要: A part time four-wheel-drive vehicle includes a first driving force transmission system and a second driving force transmission system. A control device controls the second driving force transmission system. The control device includes a road surface state determination section (S19) that determines whether a coefficient of friction of a road surface is equal to or higher than a predetermined value based on an index value regarding the coefficient of friction of the road surface, controls a dog clutch such that the dog clutch is engaged irrespective of the index value regarding the coefficient of friction of the road surface (S11) when an ignition switch is brought into the on-state (S10), and when the ignition switch is in the on state, the control device controls the dog clutch such that the dog clutch is brought into the disengaged state (S21) when it is determined that the coefficient of friction of the road surface is equal to or higher than the predetermined value S(19).
