PROBLEM TO BE SOLVED: To provide a vehicle having a power steering device capable of detecting the change in the steering resistance of a steered wheel with respect to a road surface without based on the slip of a wheel on the road surface, changing the steering assist force of the power steering device, and suppressing the kickback. SOLUTION: The steering assist force of a power steering device is changed according to the vibration of a steered wheel. The control includes one for decreasing the steering assist force according to the increase of the vertical vibration of the steered wheel, and one for increasing the steering assist force according to the increase of the horizontal vibration of the steered wheel.
