Abstract
A control system includes a transfer. The transfer is disposed in a power transmission path between the driving power source and primary driving wheels and distributes dynamic power of the driving power source to the 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 clutch mechanism is disposed in a power transmission path between the transfer and the driving power transmission shaft. A electronic control unit engages at least one of a first and second clutches and then engages the clutch mechanism on the basis of a steering state at the time of switching from a two-wheel-drive traveling state in which the clutch mechanism and the first and second clutches are disengaged to a four-wheel-drive traveling state in which the clutch mechanism and the first and second clutches are engaged.
