Patent number: 11657709Abstract: A safety confirmation support system includes: a moving object detector which detects a moving object in each of detection regions set around the vehicle; display units each associated with a different one of the detection regions; a line-of-sight detector which detects a line of sight of the driver; and a display controller which controls the display units based on detection results from the moving object detector and the line-of-sight detector. When the moving object is detected in a specified detection region, the display controller (i) displays moving object information on a specified display unit associated with the specified detection region when the line of sight is away from the specified detection region, and (ii) stops display of the moving object information on the specified display unit when the line of sight is towards the specified detection region while the moving object information is displayed on the specified display unit.Type: GrantFiled: November 30, 2021Date of Patent: May 23, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masakazu Nakazawa, Kyoko Ueda, Nobutaka Kitajima, Mutsumi Kawagoe, Tadashi Yoshida, Yasuhiro Ito, Kenji Oga
