Publication number: 20230122841Abstract: An autonomous driving system mounted on a vehicle determines a target path based on necessary information and performs vehicle travel control such that the vehicle follows the target path. A first coordinate system is a vehicle coordinate system at a first timing when the necessary information is acquired. A second coordinate system is a vehicle coordinate system at a second timing later than the first timing. The autonomous driving system calculates, based on the necessary information acquired at the first timing, a first target path defined in the first coordinate system. Then, the autonomous driving system corrects the first target path to a second target path defined in the second coordinate system by performing coordinate transformation from the first coordinate system to the second coordinate system. The autonomous driving system uses the second target path as the target path to perform the vehicle travel control.Type: ApplicationFiled: December 20, 2022Publication date: April 20, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi SONE, Yoji KUNIHIRO, Takahiro YOKOTA, Ryo IRIE, Yoshinori WATANABE, Masateru AMANO

Patent number: 11524706Abstract: An override conciliating portion executes processing to conciliate an override request during an execution of automated driving control (i.e., override conciliation processing). In the override conciliation processing, it is determined whether or not there is the override request (step S20). If the determination result of the step S20 is positive, it is determined whether or not a second automated driving mode is selected as an operation mode (step S21). If the determination result of the step S21 is negative, acceptance processing of the override request is executed (step S22). If the determination result of the step S21 is positive, invalidation processing of the override request is executed (step S23).Type: GrantFiled: April 6, 2020Date of Patent: December 13, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoji Kunihiro, Takahiro Kojo, Shun Mizoo, Takahiro Yokota, Shunsuke Tanimori, Hisaya Akatsuka, Masaki Shiota, Hirotaka Tokoro
