The invention discloses a collision early warning method, device and equipment and a storage medium. The method comprises the following steps: in a vehicle driving process, adopting at least two preset perception sensors to perceive a target object around a vehicle, and determining multi-perception fused target object data; according to the vehicle attribute information and the target object data, under the condition that the target object is in a preset detectable range and the motion direction of the target object is consistent with the motion direction of the vehicle, whether the speed of the target object meets a preset threshold condition or not is determined; if yes, the collision time is determined according to the target object speed, the target object acceleration and the interval distance, and the longitudinal collision distance is determined under the condition that the collision time meets the preset threshold value requirement; according to the longitudinal collision distance, when it is detected that an alarm condition is met, collision warning is conducted. The environment around the vehicle can be sensed, whether the vehicle has the collision risk or not is accurately analyzed, and the false alarm phenomenon is avoided under the condition that the safety of the vehicle is guaranteed.
本发明公开了一种碰撞预警方法、装置、设备以及存储介质。该方法包括:在车辆行驶的过程中,采用预设的至少两种感知传感器,对车辆周围的目标物进行感知,确定多感知融合的目标物数据;根据车辆属性信息和目标物数据,在目标物处于预设可探测范围内,且目标物的运动方向与车辆运动方向一致的情况下,确定目标物的速度是否满足预设的阈值条件;若是,则根据目标物速度、目标物加速度和间隔距离,确定碰撞时间,并在碰撞时间满足预设阈值要求的情况下,确定纵向碰撞距离;根据纵向碰撞距离,在检测到达到报警条件时,进行碰撞告警。可以对车辆周围的环境进行感知,准确分析出车辆是否有碰撞风险,在保证车辆安全的情况下,避免误报警现象的发生。
