The invention provides a ramp speed limiting method and device, a vehicle-mounted terminal and a storage medium, and the method comprises the steps: recognizing a speed limiting identifier of a ramp entrance through an image collection device, and obtaining a speed limiting value; under the condition that it is confirmed that the ramp exists in the first preset distance range through the navigation information, the driving state information and the transverse movement distance of the vehicle are obtained in real time; in the process of driving to the ramp, if the transverse movement distance meets a preset distance condition, the driving intention of the vehicle is determined based on at least one of the tire turning angle, the steering lamp condition and the steering wheel angle in the driving state information of the vehicle; and driving according to the speed limit value under the condition that the driving intention represents that the vehicle is driven into the ramp. By adopting the scheme, accurate positioning and auxiliary execution of ramp speed limiting can be realized.

    本申请提出了一种匝道限速的方法、装置、车载终端及存储介质,该方法包括:通过图像采集装置识别匝道口的限速标识,获取限速值;在通过导航信息确认第一预设距离范围内存在匝道的情况下,实时获取车辆的行驶状态信息和横向移动距离;在驶向匝道的过程中,若横向移动距离满足预设距离条件,则基于车辆的行驶状态信息中的轮胎转角,转向灯情况和方向盘角度中的至少一种,确定车辆的行驶意图;在行驶意图表征驶入匝道的情况下,按照限速值进行行驶。采用该方案,能够准确定位并辅助执行匝道限速。
