It can collide with vehicle；When object is less than safe distance at a distance from vehicle, it may be considered that the object exists and vehicle
The danger to collide continues whether it can collide with vehicle according to the velocity estimated of object.Wherein, preset safety away from
From the maximum detectable range that can be radar, it is also possible to the distance that computer is simulated according to historical data.
When object at a distance from vehicle be less than safe distance when, continue judgment object speed whether be more than or equal to it is preset
Safe speed,
If so, determining that object can collide with vehicle；If it is not, then determining that object will not collide with vehicle.
When object is less than safe distance at a distance from vehicle, further judge whether it can be with by the speed of object
Vehicle collides.When the movement speed of object is more slow, that is, when being less than or equal to preset safe speed, it is believed that
It will not collide with vehicle；When the movement speed of object is greater than preset safe speed, then it is assumed that it exists and vehicle
The risk to collide, wherein preset safe speed can be the speed that computer is simulated according to historical data.By above-mentioned
Judgment object can cope with a variety of reality scenes at a distance from vehicle and the method for object speed, improve driver and passenger's safety
While, increase flexibility.
Further, it is also possible to selectively be alarmed according to the motion state of object.Specifically, when object and vehicle away from
When from being more than or equal to safe distance, the danger to collide with vehicle is not present in object, then without alarm；
When object is less than or equal to safe speed less than the speed of safe distance and object at a distance from vehicle, rear of vehicle
Have mobile object, get off it is believed that it does not influence driver and passenger, inferior grade alarm can be carried out, to driver and passenger into
