Vehicle object detection system and method for detecting a target object in a detection area located behind and lateral of a subject vehicle

A vehicle object detection system (10), for detecting a target object (60) in a detection area (DA) located behind and/or lateral of a subject vehicle (50), the vehicle object detection system (10) comprising:

• judging means (20) configured to generate a judgement on whether the target object (60), which has been detected in the detection area (DA), is an alert object, and to output the judgement to warning means (30), which is configured to output a warning to a driver of the subject vehicle (50) based on the judgement indicating that the target object (60) is an alert object,
• wherein the judging means (20) is configured to generate the judgement in which a difference between a relative speed of the target object (60) with respect to the subject vehicle (50) and an absolute speed of the target object (60) in a transverse direction of the subject vehicle (50) is compared with a specified range;
• wherein the judgment is a determination that the target object (60) is not an alert object, and the judgement suppresses outputting the warning by the warning means (30) when the target object (60) is determined to not be an alert object.
