The invention relates to a night slope early warning method and device for an automatic driving vehicle and electronic equipment, and the method comprises the steps: obtaining the detection data of a vehicle-mounted radar about the road condition in front of the vehicle; judging the road condition and whether the obstacle vehicle in front of the vehicle disappears or not according to the detection data; when the obstacle vehicle disappears, the current observation distance is determined, the relation between the current observation distance and the safe vehicle following distance is judged, and when the current observation distance is smaller than the safe vehicle following distance, a vehicle following early warning prompt is given. After the front obstacle vehicle disappears, the default front obstacle vehicle still exists, and the current observation distance between the front obstacle vehicle and the front obstacle vehicle continues to be calculated. And when the current observation distance is smaller than the safe vehicle following distance, giving a vehicle following early warning prompt, so that the automatic driving system controls the vehicle speed, and the current observation distance is always larger than or equal to the safe vehicle following distance. The problem that effective vehicle following early warning cannot be achieved in the night ramp scene through an existing vehicle following early warning method of the automatic driving vehicle is solved.

    本申请涉及一种自动驾驶车辆的夜间斜坡预警方法、装置和电子设备,其中,该夜间斜坡预警方法包括:获取车载雷达关于自车前方路况的探测数据;根据探测数据判断路况以及自车前方的障碍车是否消失;当障碍车消失时确定当前观测距离,判断当前观测距离与安全跟车距离之间的关系,当当前观测距离小于安全跟车距离时,给出跟车预警提示。本发明在前方障碍车消失后,默认前方障碍车依旧存在,继续计算两者之间的当前观测距离。当当前观测距离小于安全跟车距离时,给出跟车预警提示,使得自动驾驶系统控制车速,使得当前观测距离始终大于或等于安全跟车距离。解决了目前自动驾驶车辆的跟车预警方法在夜间坡道场景下无法实现有效跟车预警的问题。
