Publication number: 20210011470Abstract: The likelihood of a remote driving request from a requester being unfulfilled is lowered. A server receives information regarding the remote driving request requesting a vehicle to travel by being remotely driven from a terminal of the requester, and receives information regarding a remote driving task selected by a remote driver (fulfilment agent) using a fulfilment agent operation terminal from the fulfilment agent operation terminal. A task corresponding to the received remote driving request is divided into plural remote driving tasks based on route information for the task, and information regarding at least one of the divided remote driving tasks is transmitted to the fulfilment agent operation terminal.Type: ApplicationFiled: June 2, 2020Publication date: January 14, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuji SUZUKI, Mutsumi MATSUURA, Tomoaki MIYAZAWA, Toshiki KINDO, Shunsuke TANIMORI
