Patent number: 11724694Abstract: A traveling assistance apparatus controls a safety apparatus for avoiding collision between an own vehicle and an object, based on detection information from an object detection apparatus. The assistance apparatus calculates a predicted time to collision of a target object and the own vehicle, and operates the safety apparatus in response to the predicted time to collision being equal to or less than a predetermined operation timing. In response to a steering operation by a driver for collision avoidance of the own vehicle being performed, the assistance apparatus performs operation-stop in which operation of the safety apparatus is stopped or operation-delay in which the operation timing is delayed. The assistance apparatus suppresses the operation-stop or the operation-delay in response to a target object serving as a collision avoidance target being recognized in a path of the own vehicle after the steering operation by the driver, based on the detection information.Type: GrantFiled: November 19, 2020Date of Patent: August 15, 2023Assignee: DENSO CORPORATIONInventors: Toru Takahashi, Yosuke Ito, Kei Kamiya, Ryo Takaki, Shogo Matsunaga, Takaharu Oguri, Takahiro Baba
