A vehicle wheel having a suspension and a steering device is capable of not only simplifying a driving system but also reducing the number of parts and reducing weight. The vehicle wheel includes a suspension combined with a damper and a spring in a housing of a stator of an in-wheel motor embedded in each wheel of a vehicle and a steering device directly connected to the suspension.

An independently driving wheel module includes: a base frame including an upper end fixed to a coupling surface of a vehicle body, and a rotation part coupled to the upper end of the base frame such that the rotation part is rotatable with respect to the upper end of the base frame; a connection link including a first end integrally coupled to the rotation part, and a second end having a shape extending downward from the first end of the connection link; a driving wheel disposed at a side of the second end of the connection link and coupled to the second end of the connection link; and a rotation plate including an upper and lower surfaces extending obliquely in misaligned directions, the rotation plate being interposed between the base frame and the vehicle body so as to be rotatable with respect to the base frame or the vehicle body.

A vehicle steering apparatus is configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity. The vehicle steering apparatus includes a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel, a toe adjustment actuator coupled to the steered wheel, and a controller configured to control a driving force of the toe adjustment actuator. The controller includes a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector, an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter, and a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.
