1. A method comprising:
identifying a target-type vehicle using a radar based blind spot warning (BSW) system of a host vehicle by at least:
detecting, with the BSW system, first radar reflection points reflected by an object, said first radar reflection points being outside a BSW zone of the BSW system;
setting an object area based on a distribution of a group of the first radar reflection points;
assuming the object to be another vehicle based on a positional relationship between the object area and the BSW zone;
in response to assuming the object to be another vehicle, further determining if there is at least one second radar reflection point detected inside the BSW zone; and
determining the another vehicle to be the target-type vehicle based on the detected at least one second radar reflection point.
