Abstract: A disconnect mechanism is configured to disconnect a predetermined rotating element from an engine and an auxiliary drive wheels while the vehicle is traveling in a two-wheel drive mode. The predetermined rotating element is configured to transmit power to the auxiliary drive wheels while the vehicle is traveling in a four-wheel drive mode. An electronic control unit is configured to: execute shift control when a shift condition of an automatic transmission is satisfied; selectively engage or release the disconnect mechanism based on a traveling state of the vehicle and a driver's predetermined operation; and control at least one of the automatic transmission or the disconnect mechanism such that a shift period based on the shift condition of the automatic transmission and an engagement-release period of the disconnect mechanism at least partially overlap with each other.

Abstract: In a control system, a transfer is connected to a rotation member between a driving power source and primary driving wheels and distributes dynamic power of the driving power source to secondary drive wheels. A driving power transmission shaft transmits the dynamic power of the driving power source distributed by the transfer to the secondary drive wheels. A connection-disconnection mechanism is disposed between the rotation member and the driving power transmission shaft. First and second clutches are disposed respectively between the driving power transmission shaft and right and left wheels of the secondary drive wheels. The electronic control unit is configured, when switching from a two-wheel-drive running state to a four-wheel-drive running state on the basis of a vehicle running state, to generate a transmission torque in the first clutch or the second clutch after controlling the connection-disconnection mechanism to engage the connection-disconnection mechanism.

Abstract: A rotation state of each rotating element of a four-wheel drive vehicle and an operating state of each engagement element of a disconnect mechanism, corresponding to an operating state of the disconnect mechanism, are displayed on or near a vehicle model image on a vehicle display. Thus, it is possible to inform a driver of the operating state of the disconnect mechanism at any time. Thus, the driver is able to recognize the operating state of the disconnect mechanism at any time, so the driver is able to carry out driving based on the operating state.

Abstract: Even in the case where it is difficult to increase an engine torque (Te) during switching when a running is switched to a 4WD running or a 2WD running during a 2WD_d running, an alternative control section suppresses a fluctuation in the driving force of a four-wheel drive vehicle, hence it is possible to suppress a switching shock and an unnatural feeling of deceleration occurring during the switching to the 4WD running or the 2WD running.
