The invention discloses a steer-by-wire control method, a steer-by-wire system of a vehicle and the vehicle. The steer-by-wire control method comprises the steps that a transmission ratio change signal input by a user and the current rotation angle of a steering wheel of the vehicle are obtained; according to the transmission ratio change signal and the current rotation angle of the steering wheel, the gear rotation angle needing to be adjusted of a gear of the steer-by-wire system is determined; according to the gear rotation angle, a rack of the steering system is controlled to rotate by delaying a preset time, and a steering wheel is controlled to rotate to a preset angle within the preset time so as to control the steering amplitude of the vehicle. Thus, according to the steer-by-wire control method, the steer-by-wire system of the vehicle and the vehicle, the steering amplitude of the vehicle is small and even zero degree during the period that a user switches the transmission ratio of the vehicle, and the safety and comfort of the user are improved when the user switches the transmission ratio.

    本申请公开一种线控转向控制方法、车辆的线控转向系统和车辆。线控转向控制方法包括获取用户输入的传动比变更信号和车辆的方向盘的当前转动角度;根据传动比变更信号和方向盘的当前转动角度,确定线控转向系统的齿轮所需调整的齿轮转动角度;根据齿轮转动角度控制线控转向系统的齿条延时预设时间转动,并在预设时间内控制方向盘转动至预定角度内,以控制车辆转向幅度。如此,本申请的线控转向控制方法、车辆的线控转向系统和车辆实现在用户切换车辆的传动比期间,车辆转向幅度较小甚至为零度,提高用户在切换传动比时的安全性和舒适性。
