PROBLEM TO BE SOLVED: To provide a control device which improves fuel economy by reducing traveling resistance during the control of the transmission torque of a transmission to a prescribed value or lower, in the control device of a four-wheel drive vehicle which controls the transmission torque of the transmission to the prescribed value or lower when a prescribed condition is established during the traveling of the vehicle.SOLUTION: When a condition for switching traveling to N-coasting during the traveling is established, an automatic transmission 16 is controlled to a neutral state, however, a power transmission passage between the automatic transmission 16 and a second clutch 54 is blocked by the disconnection of a first clutch 36 and the second clutch 54, and a drag turn of a rotating element constituting the power transmission passage between the automatic transmission 16 and the second clutch 54 is prevented. Accordingly, since rotation resistance caused by the drag turn of the rotating element is reduced and also traveling resistance is reduced, timing at which an accelerator pedal is pedaled in during deceleration is delayed compared with the case that the timing is accompanied by the drag turn, and fuel economy is further improved. |
