Publication number: 20240101155Abstract: A route planner detects a pedestrian from surrounding data representing a situation of surroundings of a vehicle, identifies a position of a pause-by object in the surroundings of the vehicle prompting the pedestrian to pause, creating a travel route over which the vehicle will travel when the pedestrian is detected, assuming the pedestrian will enter a road on which the vehicle will travel when the identified position of the pause-by object is not in the vicinity of the pedestrian, and assuming the pedestrian will not enter the road when the identified position of the pause-by object is in the vicinity of the pedestrian.Type: ApplicationFiled: September 19, 2023Publication date: March 28, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Nakamura, Katsuhiro Sakai, Taisuke Sugaiwa, Naoki Nagasaka, Ray Kawanishi

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

Publication number: 20240034364Abstract: A system includes an acquisition unit that acquires an operation amount or a duration count, and a switching unit that switches a driving state. The switching unit switches the driving state to the cooperative driving state when the operation amount is equal to or greater than an intervention threshold and less than a start threshold or the duration count is equal to or greater than a first threshold and less than a second threshold during the autonomous driving state, switches the driving state to the autonomous driving state when the operation amount is less than the intervention threshold or the duration count is less than the first threshold during the cooperative driving state, and switches the driving state to the manual driving state when the operation amount is equal to or greater than the start threshold or the duration count is equal to or greater than the second threshold.Type: ApplicationFiled: October 12, 2023Publication date: February 1, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiromitsu URANO, Kentaro ICHIKAWA, Taisuke SUGAIWA, Toshiki KINDO

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

Patent number: 11367291Abstract: A traffic signal display estimation system recognizes, based on the position information of a vehicle and a traffic signal information, a traffic signal included in a camera image, identifies a traffic signal display for each recognized traffic signal, and calculates, for each traffic signal, a first evaluation value indicating the certainty of the identified traffic signal display. The system integrates, based on a traffic-signal-to-traffic-signal relational information, a forward traffic signal that is ahead of the travelling direction and that the vehicle should follow and a traffic signal correlated with the forward traffic signal in terms of the traffic signal display, among a plurality of recognized traffic signals. When there is an inconsistency in traffic signal displays identified between a plurality of integrated traffic signals, the system determines a first estimated traffic signal display of the forward traffic signal, based on the first evaluation value for each traffic signal.Type: GrantFiled: July 17, 2020Date of Patent: June 21, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Hayashi, Taichi Kawanai, Kentaro Ichikawa, Taisuke Sugaiwa

Publication number: 20210349457Abstract: A vehicle controller of the automated driving vehicle capable of driverless transportation is connected with a user terminal via a communication network. The user terminal includes a terminal camera which a user who is at a desired dispatch location possesses. The automated driving vehicle includes an in-vehicle camera to capture a surrounding situation. The vehicle controller receives, from the user terminal via the communication network, a terminal camera image captured by the terminal camera from the desired dispatch location. Then, the vehicle controller identifies an image area that matches the terminal camera image from an in-vehicle camera image captured by the in-vehicle camera, and determines a pickup position capable of stopping based on positional coordinates information of the image area.Type: ApplicationFiled: April 22, 2021Publication date: November 11, 2021Inventors: Kentaro Ichikawa, Akihide Tachibana, Hiroshi Nakamura, Taisuke Sugaiwa, Katsuhiro Sakai
