Publication number: 20210300406Abstract: 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: ApplicationFiled: February 12, 2021Publication date: September 30, 2021Inventors: Hiroshi Nakamura, Akihide Tachibana, Katsuhiro Sakai, Kentaro Ichikawa, Taisuke Sugaiwa

Publication number: 20210300434Abstract: 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: ApplicationFiled: February 17, 2021Publication date: September 30, 2021Inventors: Hiroshi Nakamura, Akihide Tachibana, Katsuhiro Sakai, Kentaro Ichikawa, Taisuke Sugaiwa

Publication number: 20210245783Abstract: A control device of an automated driving vehicle is configured to perform a recognition process, a search process, and a selection process. The recognition processing is a process for recognizing that the vehicle has entered a boarding area where an occupant gets off or gets on. The search process is a process of searching for a guide in the boarding area when the vehicle enters the boarding area. The selection process is a process, as the operation of the vehicle in the boarding area, in which a first operation mode is selected when the guide is not found, and a second operation mode is selected when the guide is found. The control device is configured to mitigate safety standards of an active safety system which avoids a collision between the vehicle and surrounding objects in the second operation mode, as compared with the first operation mode.Type: ApplicationFiled: January 19, 2021Publication date: August 12, 2021Inventors: Katsuhiro Sakai, Kentaro Ichikawa, Akihide Tachibana, Hiroshi Nakamura, Taisuke Sugaiwa

Publication number: 20210027076Abstract: 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: ApplicationFiled: July 17, 2020Publication date: January 28, 2021Inventors: Yusuke Hayashi, Taichi Kawanai, Kentaro Ichikawa, Taisuke Sugaiwa
