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.
