Patent number: 11941985Abstract: Disclosed is a vehicular environment estimation device capable of accurately estimating a travel environment around own vehicle on the basis of a predicted route of a mobile object or the like, which is moving in a blind area. A vehicular environment estimation device that is mounted in the own vehicle detects a behavior of another vehicle in the vicinity of the own vehicle, and estimates a travel environment, which affects the traveling of another vehicle, on the basis of the behavior of another vehicle. For example, the presence of another vehicle, which is traveling in a blind area, is estimated on the basis of the behavior of another vehicle. Therefore, it is possible to estimate a vehicle travel environment that cannot be recognized by the own vehicle but can be recognized by another vehicle in the vicinity of the own vehicle.Type: GrantFiled: November 5, 2021Date of Patent: March 26, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Katsuhiro Sakai, Hiromitsu Urano, Toshiki Kindo

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

Patent number: 11858534Abstract: A pick-up and drop-off area, which is a predetermined area in which an automated driving vehicle stops to pick up or drop off a user, includes a downstream area existing downstream of a standard stop space and an upstream area existing upstream of the standard stop space. An automated driving system controls the automated driving vehicle so as to stop in a target stop space in the pick-up and drop-off area. When the standard stop space is available, the standard stop space is set as the target stop space. When the standard stop space is not available for the automated driving vehicle to stop to drop off the user, the automated driving system searches for an upstream available space in the upstream area and preferentially sets the upstream available space as the target stop space.Type: GrantFiled: February 17, 2021Date of Patent: January 2, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Nakamura, Akihide Tachibana, Katsuhiro Sakai, Kentaro Ichikawa, Taisuke Sugaiwa

Publication number: 20230410658Abstract: The driver assistance system of the present disclosure is configured to execute processing comprising following four processes. The first process is to extract risk target information related to a risk target that causes a collision risk to a vehicle from information related to a peripheral situation of the vehicle. The second process is to obtain natural phenomenon information related to a natural phenomenon that affects the risk target. The third process is to determine a risk parameter that quantifies the collision risk based on the risk target information and the natural phenomenon information. The fourth process is to determine a manipulated variable of an actuator for controlling movement of the vehicle to reduce the collision risk based on the risk parameter.Type: ApplicationFiled: May 24, 2023Publication date: December 21, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ray KAWANISHI, Katsuhiro SAKAI, Taisuke SUGAIWA, Hiroshi NAKAMURA, Naoki NAGASAKA

Patent number: 11814068Abstract: An automated driving system controls an automated driving vehicle. A plurality of stop lots are virtually arranged in a pick-up and drop-off area in which the automated driving vehicle stops to pick up or drop off a user. An order of priority of the plurality of stop lots is set. The automated driving system selects a stop lot one by one in the order of priority and determines whether or not the selected stop lot is available for the automated driving vehicle to stop. When the selected stop lot is available for the automated driving vehicle to stop, the selected stop lot is set as a target stop lot. The automated driving system controls the automated driving vehicle so as to stop in the target stop lot.Type: GrantFiled: February 12, 2021Date of Patent: November 14, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Nakamura, Akihide Tachibana, Katsuhiro Sakai, Kentaro Ichikawa, Taisuke Sugaiwa
