Abstract: A vehicle system includes a drive source configured to generate torque for driving a vehicle, wheels including rear wheels that are primary driving wheels and front wheels that are auxiliary driving wheels, a torque distribution mechanism configured to distribute the torque of the drive source to the front wheels and the rear wheels, a steering wheel configured to be operated by a driver, and a controller configured to control at least the torque distribution mechanism. When the steering wheel is steered in reverse and a yaw rate difference related value related to a difference between a target yaw rate to be generated on the vehicle according to the steering of the steering wheel and an actual yaw rate actually generated on the vehicle is greater than or equal to a first predetermined value, the controller controls the torque distribution mechanism to reduce the torque distributed to the rear wheels.
