Publication number: 20210070287Abstract: 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: ApplicationFiled: November 19, 2020Publication date: March 11, 2021Inventors: Toru TAKAHASHI, Yosuke ITO, Kei KAMIYA, Ryo TAKAKI, Shogo MATSUNAGA, Takaharu OGURI, Takahiro BABA
