Steering-by-wire system, steering-by-wire control device, and steering-by-wire control method

According to one embodiment of the steer-by-wire system, the steer-by-wire control device, and the steer-by-wire control method of the present invention, a reaction force generating device generates a reaction force when a sideslip of a vehicle occurs. A sideslip-time reaction torque, which decreases or increases in accordance with a basic reaction torque obtained from the steering angle of a steering wheel, the steering angle, the vehicle speed of the vehicle, and the engine torque of the steering engine, is output as a reaction torque. As a result, the sideslip state of the vehicle can be appropriately transmitted to the driver through the steering wheel. 根据本发明的线控转向系统、线控转向控制装置以及线控转向控制方法，作为其中一个实施方式，反力发生装置在车辆发生侧滑的情况下，将相对于由方向盘的转向角求得的基本反力扭矩并根据所述转向角、车辆的车速、变向发动机的发动机扭矩而减少或者增加的侧滑时反力扭矩作为反力扭矩而输出。由此，能够将车辆的侧滑状态通过方向盘适当地传递至驾驶员。
