Patent number: 11607362Abstract: When it is determined that a presence of a traffic light is not recognized in an image acquired by a first image acquisition operation by a camera, the presence of the traffic light is recognized in an image acquired by a second image acquisition operation in which a recognition accuracy of the presence of the traffic light is improved. In this second image acquisition operation, it is assumed that a pedestrian is stopped in front of a pedestrian crossing, and there is little demand for increasing a detection speed of objects such as moving objects present in a surrounding area. Thus, it is possible to sufficiently obtain the recognition accuracy of the traffic light by the second image acquisition operation that gives priority to the recognition accuracy of the presence of the traffic light.Type: GrantFiled: October 18, 2021Date of Patent: March 21, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroaki Kawamura, Kohei Shintani

Publication number: 20220370282Abstract: When a frontmost white line of a crosswalk cannot be detected due to an obstacle existing on the crosswalk, an edge position of the obstacle closer to a pedestrian in an image acquired by a camera is set as the frontmost white line of the crosswalk. As a result, a vibration generation device vibrates in a pattern that urges the pedestrian to stop at the time when the pedestrian reaches a position before the edge position of the obstacle closer to the pedestrian, so that a stop notification for walking can be appropriately performed to the pedestrian even when the obstacle exists on the crosswalk.Type: ApplicationFiled: March 4, 2022Publication date: November 24, 2022Inventors: Hiroaki KAWAMURA, Kohei SHINTANI
