Publication number: 20220063721Abstract: A travel controller detects a non-lane zone within a predetermined distance ahead of a current position of a vehicle. The non-lane zone lacks lanes. The travel controller controls travel of the vehicle in the non-lane zone so as to keep the position of the vehicle relative to the width of a whole road. When an expected position of the vehicle at the end of the non-lane zone straddles a lane line, the travel controller controls travel of the vehicle so as to move to a lane having a larger overlap with the vehicle, prior to control of travel of the vehicle to keep the position of the vehicle relative to the width of the whole road.Type: ApplicationFiled: August 19, 2021Publication date: March 3, 2022Inventors: Takao Kashu, Yasutaka Teramae, Hirotaka Kato, Ryo Masutani, Ichi Gi

Publication number: 20210403028Abstract: A route selection device includes a processor configured to identify a position of a lane on which a vehicle is traveling; search for candidate partial routes leading from a current position of the vehicle to a waypoint on a route leading from a start point to a destination, the waypoint being located between the current position and the destination; determine a lane change location where a lane change will be made for each of the candidate partial routes found by searching; and select, as a partial route, a candidate partial route having a minimum total score regarding the lane change location from the candidate partial routes found by searching. The score is weighted depending on the position of the determined lane change location or whether a lane change at the lane change location can be controlled by a travel controller.Type: ApplicationFiled: June 16, 2021Publication date: December 30, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao KASHU, Yasutaka TERAMAE, Hirotaka KATO, Shuichi MORIMOTO, Ryo MASUTANI, Ichi GI
