Patent number: 12157477Abstract: Processing to set a control mode of driving control is performed. In this setting processing, it is determined whether or not a predetermined condition in which a tracking performance of a vehicle state with respect to a target vehicle state decreases is satisfied. Then, when it is determined that the predetermined condition is satisfied, the control mode is switched from a normal mode to a temporary mode. In the temporary mode, generation of a driving plan is stopped. Alternatively, updating or referring to the driving plan generated while it is determined that the predetermined condition is satisfied is prohibited. Alternatively, an instruction value for control calculated using a target control value and a current vehicle state in the driving plan generated while it is determined that the predetermined condition is satisfied is modified.Type: GrantFiled: October 31, 2022Date of Patent: December 3, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Okamoto, Yoshinori Watanabe, Sho Amagai, Atsushi Sone, Atsushi Kodama, Kosuke Futagami, Yosuke Hirate
