Patent number: 12286108Abstract: A travel controller generates routes respectively leading from a current lane being traveled by a vehicle to lanes except the current lane. The lanes are demarcated by lane lines and located forward in a travel direction beyond a lack-of-lane zone having no lane line. The travel controller further identifies one of the routes corresponding to a path along which the vehicle is traveling the lack-of-lane zone as a route being traveled. The path is calculated with data outputted from a sensor mounted on the vehicle. Then the travel controller controls travel of the vehicle to keep one of the lanes to which the route being traveled leads.Type: GrantFiled: March 21, 2022Date of Patent: April 29, 2025Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yu Okada, Shota Fujii, Eiki Kitagawa, Suzuka Kondo, Soichi Yoshino, Takuo Kaneko

Patent number: 12012117Abstract: A travel controller sets a check level depending on the situation of a lane change from a travel lane of a vehicle to a different lane before the lane change. The travel controller requests a first pre-lane-change action for the check at the lane change of the driver with a notification device when the check level is higher than a level threshold, and requests a second pre-lane-change action for the check at the lane change of the driver with the notification device when the check level is lower than the level threshold. The travel controller controls travel of the vehicle to make the lane change in the case that the driver has performed the first or second pre-lane-change action having been requested and that the situation around the vehicle satisfies a surrounding condition to be satisfied at the lane change.Type: GrantFiled: March 15, 2022Date of Patent: June 18, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Soichi Yoshino, Shota Fujii, Yu Okada, Takuo Kaneko, Suzuka Kondo, Eiki Kitagawa
