The invention relates to a vehicle front collision warning method and system, and relates to the technical field of vehicle front collision warning and automatic emergency braking systems.The method comprises the steps that the traversing speed of a traversing target object in front of a vehicle is obtained in real time; when it is detected that the traversing target object is shielded and appears again, the shielded duration of the traversing target object is obtained; determining an ADAS function judgment speed according to the shielded duration of the traversing target object, the traversing speed of the traversing target object, a preset speed change rate threshold value and a preset speed stability condition; and inputting the ADAS function judgment speed into an ADAS processing module of the vehicle. By adopting the method and the device, false triggering of front collision alarming and automatic emergency braking functions of the ADAS processing module can be reduced, and the driving experience of a driver is improved.

    本申请涉及一种车辆前碰撞报警方法及系统,涉及汽车前碰撞报警和自动紧急制动系统技术领域,所述方法包括:实时获取车辆前方的横穿目标物的横穿速度;当检测到所述横穿目标物被遮挡并再次出现时,获取所述横穿目标物的被遮挡时长;根据所述横穿目标物的被遮挡时长、所述横穿目标物的横穿速度、预设的速度变化率阈值和预设的速度稳定条件,确定ADAS功能判断速度;将所述ADAS功能判断速度输入所述车辆的ADAS处理模块。采用本申请可以减少ADAS处理模块的前碰撞报警和自动紧急制动功能的误触发,提升驾驶员的驾驶体验。
