The invention relates to the technical field of automatic driving, and discloses a vehicle speed control method and system for a ramp, a vehicle and a storage medium. According to the method, navigation map information including a ramp speed limiting road section and real-time position information is obtained, and if the current vehicle runs in the ramp speed limiting road section, the current vehicle is driven to the ramp speed limiting road section; if yes, determining a speed limit flag bit between the current vehicle and the ramp speed limit road section according to the real-time position information, then matching a target vehicle speed threshold value according to the speed limit flag bit, and controlling the real-time vehicle speed of the current vehicle within the target vehicle speed threshold value so as to limit the speed of the current vehicle. The navigation map is used as a basis to determine the position relationship between the current vehicle and the target ramp, and then the target vehicle speed threshold is obtained through matching to limit the speed of the vehicle, so that the problem of inaccurate ramp identification caused by low environmental visibility, poor road conditions and the like is avoided, the speed limiting accuracy of the vehicle running on the ramp is improved, and the driving safety of the vehicle is improved. And the safety of automatic driving is improved.

    本发明涉及自动驾驶技术领域,公开了一种用于匝道的车辆速度控制方法、系统、车辆及存储介质,该方法通过获取包含匝道限速路段和实时位置信息的导航地图信息,若当前车辆行驶在匝道限速路段内,则根据实时位置信息确定当前车辆与匝道限速路段之间的限速标志位,进而根据限速标志位匹配目标车速阈值,并将当前车辆的实时车速控制在目标车速阈值内,以对当前车辆实行限速,相较于摄像头或雷达作为匝道识别依据,将导航地图作为依据确定当前车辆与目标匝道之间的位置关系,进而匹配得到目标车速阈值进行车辆限速,避免因环境能见度低、路况差等原因造成的匝道识别不准确的问题,从而提高车辆在匝道行驶的限速准确率,提高自动驾驶的安全性。
