The invention relates to the technical field of automatic driving, in particular to an automatic cruise speed limit value determination method and device, equipment, a storage medium and a product. According to the method, the minimum value of a first speed limiting set value recognized by a first traffic sign recognition assembly and a second speed limiting set value recognized by a second traffic sign recognition assembly is compared with the initial cruise speed, and the recognition precision of the first traffic sign recognition assembly is smaller than that of the second traffic sign recognition assembly; if the minimum value is smaller than the initial cruise speed, whether the difference between the initial cruise speed and the minimum value is smaller than a preset overspeed adjustment threshold value or not is judged; if yes, vehicle speed adjustment request information is sent to the user side; and if the corresponding vehicle speed adjustment confirmation information is received within the preset feedback time, the minimum value serves as the target cruise vehicle speed. According to the method, two traffic sign recognition assemblies with different precisions are combined, and the cruising speed is adjusted in time after confirmation, so that the safety of automatic driving is improved.

    本申请涉及自动驾驶技术领域,尤其涉及一种自动巡航限速值确定方法、装置、设备、存储介质及产品。该方法将第一交通标志识别组件识别出的第一限速设定值和第二交通标志识别组件识别出的第二限速设定值中的最小值与初始巡航车速进行对比,其中,第一交通标志识别组件的识别精度小于第二交通标志识别组件;若最小值小于初始巡航车速,判断初始巡航车速与最小值之差是否小于预设超速调整阈值;若是,向用户端发出车速调整请求信息;若在预设反馈时间内接收到对应的车速调整确认信息,将最小值作为目标巡航车速。该方法通过结合两个不同精度的交通标志识别组件,并在确认后及时调整巡航车速,提高了自动驾驶的安全性。
