  • Publication number: 20240135824
    Abstract: A vehicle object detection system configured to judge whether a target object which has been detected in the detection area is an alert object, and to output a result of 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 based on judging the target object to be an alert object, wherein the system is configured to judge, in response to the subject vehicle being detected to make or have made a turn, whether the target object detected in the detection area is an alert object based on a trailing trajectory of the subject vehicle being a calculated trajectory the subject vehicle has passed during turning and/or after turning, and further based on a current relative position of the target object with respect to the subject vehicle.

  • Publication number: 20240132095
    Abstract: A blind spot detection control apparatus for a vehicle, configured for judging whether an object detected during a detection cycle in blind spot zone of the vehicle is an alert object, for outputting a result of judgement to a warning which warns a driver of vehicle that an object is present in blind spot zone based on judging that object detected in blind spot zone is an alert object, wherein apparatus is configured to judge whether an object detected in blind spot zone is an alert object by comparing detection parameters relating to a current target object detected in blind spot zone during a current detection cycle with detection parameters relating to a reference moving object corresponding to a target object detected in blind spot zone at least during a previous detection cycle.

  • Patent number: 11798417
    Abstract: A driving assistance device includes an object detection unit, an acquisition unit acquiring a first value of a relative speed of an approaching object with respect to an own vehicle, a ghost determination unit, and an assistance determination unit. The ghost determination unit calculates a second value of the relative speed of the approaching object in accordance with a speed of the own vehicle and a value of the relative speed of a following object located between the own vehicle and the approaching object; calculates, as a speed difference, an absolute difference between the first value of the relative speed and the second value of the relative speed; calculates, as an azimuth difference, an absolute difference between an azimuth of the following object and an azimuth of the approaching object; and determines whether the approaching object is the ghost target based on the speed difference and the azimuth difference.

  • Publication number: 20220252719
    Abstract: An object detection apparatus is mounted to a vehicle and detects an object by a reflected wave of a probe wave. The object detection apparatus calculates a relative velocity of the object to the vehicle, estimates an azimuth of the object relative to the vehicle, and corrects the estimated azimuth. The object detection apparatus generates a velocity-azimuth curve that indicates a relationship between the relative velocity of the object and the azimuth of the object that is calculated based on a theoretical mounting angle of the object detection apparatus, supplies a weight to an azimuth error that is an error between the velocity-azimuth curve and the estimated azimuth, based on the estimated azimuth, and calculates a correction value of the estimated azimuth by calculating, as an actual mounting angle deviation of the object detection apparatus, a weighted average value of the azimuth error to which the weight is supplied.
