  • Publication number: 20240383471
    Abstract: A collision damage reduction device of the present disclosure includes: a departure judgment unit which detects that a vehicle is in a departing state; a departing-state acceleration velocity determination unit which determines upper limits for an acceleration and a velocity of the vehicle, when the vehicle is in the departing state; and a control unit which controls the acceleration and the velocity of the vehicle on the basis of upper limits determined by the departing-state acceleration velocity determination unit. Even in a situation in which an obstacle is not detected, the departing-state acceleration velocity determination unit determines, as first upper limits, such upper limits for the acceleration and the velocity that do not cause serious damage even if the vehicle contacts with assumed said obstacle.

  • Publication number: 20240288574
    Abstract: This object detection device includes: a radar erroneous detection determination unit which sets, as true, a radar erroneous detection suspicion flag for radar detected object information determined to be suspected as erroneous detection; a fusion processing unit which outputs fusion object information on the basis of second sensor detected object information and the radar detected object information acquired from the radar erroneous detection determination unit; and a radar erroneous detection removal unit which removes fusion object information determined to be suspected as erroneous detection. When a fusion object is determined to be an object detected by only a radar, the fusion processing unit sets a single-sensor detection flag for the fusion object information, as true. The radar erroneous detection removal unit removes the fusion object information for which the radar erroneous detection suspicion flag is true and the single-sensor detection flag is true.
