Abstract
A vehicle steering system includes an axial force sensor that detects a vibration of a vehicle wheel; and a control device including an FFT analysis unit that resolves the vibration of the vehicle wheel into a power spectrum. The control device executes compensation assist control that suppresses one of a deflection of the vehicle and a vibration of a steering component that are caused by a puncture or a burst of the vehicle wheel, based on the vibration calculated based on a radius of the vehicle wheel when the vehicle wheel is normal and a vehicle speed and an abnormal-wheel frequency calculated based on a radius of the vehicle wheel when the vehicle wheel is punctured or burst and the vehicle speed.
