The invention relates to a steering ratio switching method, a steering ratio switching device and a vehicle. The steering ratio switching method is applied to the steer-by-wire system and comprises the steps that a user instruction for switching a steering ratio is obtained; acquiring a driving state of the vehicle; forming a switching instruction according to the driving state and the user instruction; and switching the steering ratio to a numerical value matched with the user instruction according to the switching instruction. According to the steering ratio switching method, various driving states of the vehicle can be considered, the switching instruction is specifically formed in combination with the driving state and the user instruction, the driving influence on a driver in the steering ratio switching process can be reduced, the driving experience of the driver is more quiet and stable, and the user experience is improved. Therefore, the safety and the stability of the steering ratio switching method can be improved.

    本申请涉及一种转向比切换方法、转向比切换装置以及车辆。转向比切换方法应用于线控转向系统,包括:获取切换转向比的用户指令;获取车辆的行驶状态;根据所述行驶状态和所述用户指令形成切换指令;以及根据所述切换指令,将所述转向比切换至与所述用户指令匹配的数值。转向比切换方法能够考虑到车辆行驶的各种状态,并且结合行驶状态和用户指令来针对性形成切换指令,有利于降低转向比切换过程中对驾驶员的驾驶影响,让驾驶员的驾驶体验更加安静与平稳,因此能够提高转向比切换方法的安全性以及稳定性。
