Patent number: 11919541Abstract: Automated drive system comprises a control device. The control device executes run control processing of the automated drive vehicle provided to a driverless transportation service. The run control processing includes carriage porch control processing. The carriage porch control processing is performed when a PUDO position of a user corresponds to a carriage porch of a facility including a zone for run and a zone for PUDO. In the carriage porch control processing, it is judged whether or not there is an empty space in the zone for PUDO. If it is judged that there is no empty space, it is judged whether or not a quick PUDO of the user in the carriage porch is expected. If it is judged that the quick PUDO is expected, a target PUDO position to perform a PUDO action of the automated drive vehicle is set to any position in the zone for run.Type: GrantFiled: April 19, 2021Date of Patent: March 5, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Nakamura, Akihide Tachibana, Katsuhiro Sakai, Kentaro Ichikawa, Taisuke Sugaiwa
