Abstract: A vehicle object detection system for detecting a target object in a detection area located behind and/or lateral of a subject vehicle, that is configured to generate a judgement on whether a target object which has been detected in the detection area is an alert object, to output the judgement to warning means which is configured to output a warning to a driver of the subject vehicle based on the judgement indicating that the target object is an alert object, and to generate the judgement based on: one or more positions of one or more other objects other than the target object being detected to be located between the target object and the subject vehicle, and a time period during which the target object is detected, being smaller than a specified period of time.

Abstract: A vehicle object detection system configured to generate a judgement on whether a target object which has been detected in 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 based on the judgement indicating that the target object is an alert object, wherein system is configured to generate the judgement based on at least one of a comparison of a difference between a relative speed of the target object with respect to the subject vehicle and an absolute speed of the target object in a transverse direction of the subject vehicle with a specified range, and a comparison of an estimated arrival position of the target object, which is a position the target object is estimated to reach in the detection area in a specific period of time.

Abstract: A driving assistance device includes: a radar provided in a rear portion of an own vehicle, and which transmits a radio wave to a predetermined detection region directed toward a rear side and a lateral side of the own vehicle, receives the radio wave reflected in the detection region, and detects a target around the own vehicle based on the received radio wave; a control device which executes driving assistance control including at least one of alert directed to a driver or braking of the own vehicle when a target is detected by the radar device; and a door opening detection device which detects whether a predetermined door, which possibly enters the detection region when the door is opened, is opened among doors of the own vehicle. The control device suppresses the driving assistance control when the opening of the door is detected by the door opening detection device.
