Abstract
A device and method of controlling suspension settings according to a steering mode of a vehicle determines an attitude of a vehicle to easily secure a driver's field of view depending on various steering modes of the vehicle and determines a roll angle or pitch angle of the vehicle accordingly to control a suspension, so that a driver's anxiety or uncomfortableness caused by steering modes may be eliminated by securing the driver's field of view, and a driver's ride quality may be improved by allowing the driver to identify driving conditions that vary depending on a driving mode from a driver's view.
