Publication number: 20240067172Abstract: A moving body control system determines, during execution of a remote operation of a moving body, whether a predetermined condition is satisfied based on driving environment information indicating the driving environment for the moving body. When the predetermined condition is satisfied, the moving body control system issues a notification to rearward of the moving body, the notification prompting to pass the moving body. Meanwhile, when the predetermined condition is not satisfied, the moving body control system prohibit issuance of the notification. The predetermined condition includes at least a first condition that “the moving body is in an environment where passing is legally permitted”, and a second condition that “safety when the moving body is passed is ensured”.Type: ApplicationFiled: August 14, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kosuke AKATSUKA, Rio SUDA
