The invention discloses a vehicle emergency braking method, device and equipment and a storage medium, and relates to the technical field of vehicle control, and the method comprises the steps that obstacle information and vehicle information are obtained, and effective obstacles are obtained according to the obstacle information and the vehicle information; performing multiple times of screening according to the effective obstacle target to obtain a target obstacle; identifying a driving scene of the target obstacle, and obtaining a scene time threshold value of the target obstacle based on the driving scene; vehicle emergency braking is carried out according to the scene time threshold value of the target obstacle, the obstacle type and the obstacle confidence coefficient; according to the method, barriers are screened by using a hierarchical structure of pre-screening, final screening and scene processing, so that the barriers can be effectively screened out, barrier targets which are high in confidence and related to a vehicle can be reserved, the probability of error occurrence is reduced, the targets after pre-screening are further subjected to multi-layer screening, the calculation redundancy is reduced, and the calculation efficiency is improved. Scene processing is added, so that the braking distance of various types of obstacles in different scenes is effectively ensured.
本申请公开了一种车辆紧急制动方法、装置、设备及存储介质,涉及车辆控制技术领域,公开了:获取障碍物信息和自车信息,根据障碍物信息和自车信息得到有效障碍物;根据有效障碍目标进行多次筛选,得到目标障碍物;识别目标障碍物的行驶场景,基于行驶场景得到目标障碍物的场景时间阈值;根据目标障碍物的场景时间阈值、障碍物类型以及障碍物置信度进行车辆紧急制动;该方法通过利用预筛选、最终筛选和场景处理的分层结构对障碍物进行筛选,可以有效筛选出障碍物,保留高置信度、与自车相关的障碍物目标,减少误差发生的概率,对预筛选后的目标做进一步的多层筛选,降低计算的冗余,增加场景处理有效保证各类型障碍物在不同场景下的刹停距离。
