The invention discloses a vehicle speed limit determination method which comprises the steps that first speed limit information from a first map, second speed limit information from a second map and third speed limit information recognized by a vehicle-mounted camera at the current moment are obtained, and the positioning precision of the first map is higher than that of the second map; screening effective speed limit information from the first speed limit information, the second speed limit information and the third speed limit information; and under the condition that the effective speed limit information is screened out, the effective speed limit information is fused based on a preset speed limit fusion strategy, target speed limit information of the current vehicle is obtained, and the target speed limit information indicates the running speed upper limit of the current vehicle on the current road section. According to the vehicle speed limit determination method, the accuracy and reliability of vehicle speed limit determination can be improved, and then the safety of vehicle automatic driving is improved.

    本申请公开了一种车辆限速确定方法,包括:获取当前时刻的源于第一地图的第一限速信息、源于第二地图的第二限速信息和车载摄像头识别到的第三限速信息,第一地图的定位精度高于第二地图;从第一限速信息、第二限速信息和第三限速信息中筛选有效限速信息;在筛选出有效限速信息的情况下,基于预设限速融合策略对有效限速信息进行融合,得到当前车辆的目标限速信息,目标限速信息指示当前车辆在当前路段上的行驶速度上限。本申请的车辆限速确定方法,能够提高车辆限速确定的准确性和可靠性,进而提高车辆自动驾驶的安全性。
