Radar Based Target-Type Vehicle Detection

A method of identifying target-type vehicle through radar based blind spot warning (BSW) system of a host vehicle, comprising: detecting a first radar reflection point reflected by an object, said first radar reflection point being outside the BSW zone of the BSW system; setting an object area based on the distribution of groups of the first radar reflection point; assuming the object to be other vehicle based on the positional relationship between the object area and the BSW zone; detecting a second radar reflection point inside the BSW zone; and determining the other vehicle to be the target-type vehicle based on the detected second radar reflection point. The target-type vehicle is trailer or coach.
