The invention discloses a ramp speed limit prompting method and device, a vehicle and a storage medium. According to the method, if a vehicle identifies a ramp and detects a ramp speed limit board in a current driving environment, whether the vehicle is in a steerable area is determined based on a first longitudinal distance between the vehicle and a first vertex of a first intervisibility triangular area and a second longitudinal distance between the vehicle and a second vertex of a second intervisibility triangular area; if the vehicle is in the steerable area, determining whether the vehicle is driven into a ramp or not within a reference time length; if it is determined that the vehicle drives into the ramp, prompt information is output based on the speed limit value corresponding to the ramp speed limit board. Whether the vehicle is in the steerable area is judged according to the first longitudinal distance between the vehicle and the first vertex and the second longitudinal distance between the vehicle and the second vertex, and then corresponding prompt information is output under the condition that it is determined that the vehicle is driven into the ramp, so that it is ensured that the prompt information is output after the vehicle is driven into the ramp. And the probability of false prompting of the ramp speed limit information is reduced.

    本申请公开了一种匝道限速提示方法、装置、车辆以及存储介质。该方法通过若本车在当前行车环境中识别到匝道并且检测到匝道限速牌,则基于本车与第一通视三角区域的第一顶点之间的第一纵向距离,和本车与第二通视三角区域的第二顶点之间的第二纵向距离,确定本车是否处于可转向区域;若本车处于可转向区域,则确定本车在参考时长内是否驶入匝道;若确定本车驶入匝道,则基于匝道限速牌对应的限速值输出提示信息。通过本车与第一顶点之间的第一纵向距离以及和第二顶点之间的第二纵向距离,判断本车是否处于可转向区域,进而在确定本车驶入匝道的情况下输出相应的提示信息,以确保提示信息是在车辆驶入匝道后输出的,降低匝道限速信息误提示的概率。
