  • Patent number: 11568746
    Abstract: 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.

  • Patent number: 11543833
    Abstract: A vehicle control device includes a communication unit configured to be communicable with an autonomous driving vehicle that autonomously travels, a determination unit configured to determine whether there is a possibility that communication between the autonomous driving vehicle and the vehicle control device is disconnected, based on information indicating a communication status between the autonomous driving vehicle and the vehicle control device, and a travel instruction unit configured to transmit, when there is the possibility that the communication between the autonomous driving vehicle and the vehicle control device is disconnected, a travel instruction to the autonomous driving vehicle via the communication unit before the communication between the autonomous driving vehicle and the vehicle control device is disconnected. The travel instruction matches conditions associated with travel control of the autonomous driving vehicle.

  • Publication number: 20210347385
    Abstract: 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.

  • Publication number: 20210349457
    Abstract: 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.

  • Publication number: 20210300434
    Abstract: 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.

  • Publication number: 20210300406
    Abstract: 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.

  • Publication number: 20210245783
    Abstract: 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.
