The invention discloses a backward traversing early warning method and system and a vehicle, and the method comprises the steps: obtaining detection data of a reversing radar on the vehicle, the detection data comprises object information of an object located in a radar detection range, the object information comprises motion information of the object and position information of the object, determining an alarm region matched with a parking angle of the vehicle, determining a target object which is located in the alarm area and has the highest collision risk with the vehicle in the objects based on the detection data, determining whether the target object meets an alarm condition or not based on object information of the target object, giving an alarm when the target object meets the alarm condition, and giving an alarm when the target object does not meet the alarm condition. And no alarm is given. The adaptive alarm area is determined according to the parking angle of the vehicle, so that the backward traversing early warning method provided by the embodiment of the invention can adapt to various different parking angles, accurate early warning can be performed at different parking angles, and the false alarm probability is reduced.
本申请公开了一种后向横穿预警方法、系统及车辆,获取车辆上倒车雷达的探测数据,探测数据包括位于雷达探测范围内的对象的对象信息,对象信息包括对象的运动信息和对象的位置信息,确定与车辆的停车角度适配的报警区域,基于探测数据确定对象中位于报警区域内,且与车辆的碰撞风险最高的目标对象,基于目标对象的对象信息确定目标对象是否满足报警条件,在确定目标对象满足报警条件的情况下,进行报警,在确定目标对象不满足报警条件的情况下,不进行报警。根据车辆的停车角度确定适配的报警区域,使得本实施例提供的后向横穿预警方法能够适配多种不同的停车角度下,可以在不同停车角度下进行准确预警,降低误报概率。
