VEHICLE OBJECT DETECTION SYSTEM AND METHOD FOR DETECTING A TARGET OBJECT IN A DETECTION AREA LOCATED BEHIND A SUBJECT VEHICLE

A vehicle object detection system configured to generate a judgement on whether a target object which has been detected to enter the detection area is an alert object, and to output the judgement to a warning which is configured to output a warning to a driver of the subject vehicle that a target object is present in the detection area behind the subject vehicle based on the judgement indicating that the target object is an alert object, wherein the system is configured to delay generating the judgment until a specified period of time has elapsed from a point in time when the target object is detected to enter a detectable area included in a field of view of a sensor, wherein the detectable area overlaps with only a part of the detection area.
