The invention relates to an AEB triggering method and device based on traffic conflicts and a medium. The AEB triggering method comprises the following steps that at least one target vehicle in an environment is recognized, the vehicle type of the target vehicle is determined based on a preset target detection model, and the preset target vehicle mass is matched based on the vehicle type; based on the obtained relative distance between the vehicle and the target vehicle and the target vehicle speed, the difference value of the braking distance is calculated; calculating collision loss momentum based on the target vehicle speed, the target vehicle mass, the obtained vehicle speed and preset vehicle mass information; and based on the difference value of the braking distance and the collision loss momentum, the risk degree is calculated according to the vehicle type, and when the risk degree meets a preset condition, AEB is triggered. Compared with the prior art, the driving safety of the vehicle is ensured, and meanwhile, the comfort is considered.

本发明涉及一种基于交通冲突的AEB触发方法、设备、介质，包括如下步骤：识别环境内的至少一个目标车辆，基于预设的目标检测模型确定目标车辆的车辆类型，基于所述车辆类型匹配预设的目标车辆质量；基于获取到的本车与所述目标车辆的相对距离和目标车辆速度，计算制动距离的差值；基于所述目标车辆速度、所述目标车辆质量、获取到的本车速度以及预置的本车质量信息，计算碰撞损失动量；基于所述制动距离的差值和所述碰撞损失动量，并根据所述车辆类型计算风险度，当所述风险度满足预定条件时触发AEB。与现有技术相比，本发明保证车辆驾驶安全性的同时兼顾舒适性。
