  • Patent number: 10437257
    Abstract: A vehicle includes an autonomous driving system that can determine whether an interruption of autonomous driving control is required. The autonomous driving system can determine that interruption is required based on an evaluation value dependent upon a target position and a control position, and an evaluation value threshold. The vehicle further includes communication systems that provide interruption information on the autonomous driving control to an occupant of the vehicle and to other vehicles around the vehicle if it is determined that the interruption of the autonomous driving control is required.

  • Publication number: 20190300016
    Abstract: During automated driving of a vehicle, an automated driving system searches for a driver's acceptable range being a range of an automated driving parameter accepted by a driver of the vehicle. A positive response is the driver's response when the automated driving parameter is within the driver's acceptable range. A negative response is the driver's response when the automated driving parameter is beyond the driver's acceptable range. The automated driving system executes: parameter change processing that actively changes the automated driving parameter; response determination processing that determines whether the driver's response to the parameter change processing is the positive response or the negative response based on a result of detection by a driver response detection device; and search processing that repeatedly executes the parameter change processing and the response determination processing to search for the driver's acceptable range.

  • Patent number: 10331139
    Abstract: In a navigation device for the autonomously driving vehicle, a continuation degree of autonomous driving on the paths found by a path searcher is calculated by a continuation degree calculator. In addition, a path for the host vehicle to travel is selected by the path selector from the paths found by the path searcher based on the degree of continuation of the autonomous driving. Therefore, it is possible to select a path for the host vehicle travelling by autonomous driving while including the degree of continuation of the autonomous driving in conditions for selecting the path.

  • Patent number: 10292684
    Abstract: An ultrasound diagnosis apparatus includes processing circuitry. The processing circuitry obtains three-dimensional medical image data, taken by using an ultrasound probe, of a region including a heart valve of a patient and a catheter inserted into a heart chamber of the patient. The processing circuitry determines an advancing direction of a tip end part of the catheter by obtaining information on a position and a posture of the tip end part included in the three-dimensional medical image data, by using at least one selected from shape information indicating the shape of the tip end part and reflection characteristic information indicating ultrasound reflection characteristics of the tip end part. The processing circuitry generates a display image from the three-dimensional medical image data in accordance with the position and the advancing direction of the tip end part. The processing circuitry causes the display image to be displayed.

  • Publication number: 20190147671
    Abstract: A driverless transportation system includes an autonomous driving vehicle and a management server. A check code includes: a vehicle code unique to the autonomous driving vehicle; and a passcode whose value changes each time it is generated. In deactivation processing, the autonomous driving vehicle newly generates the passcode, stores the check code including the newly-generated passcode, as a first check code, and transmits the first check code to the management server. The management server stores the first check code as a stored check code. In order to activate the autonomous driving vehicle, the management server transmits an activation instruction and the stored check code to the autonomous driving vehicle. In response to that, the autonomous driving vehicle reads the check code from its memory device, as a second check code, and determines whether or not the second check code and the stored check code match.

  • Publication number: 20190137999
    Abstract: An autonomous running vehicle transmits a camera image around the vehicle photographed by a camera to a remote monitoring center. An obstacle is detected on the basis of information obtained from autonomous sensors including the camera. When an obstacle is detected, the autonomous running vehicle is automatically stopped. The remote monitoring center determines, when the autonomous running vehicle automatically stops, whether or not the run of the autonomous running vehicle is permitted to restart on the basis of the received camera video. When it is determined that the autonomous running vehicle can be restarted, a departure signal is transmitted to the autonomous running vehicle. When the departure signal is received from the remote monitoring center, the autonomous running vehicle restarts running.

  • Publication number: 20190139328
    Abstract: A driverless transportation system includes: an autonomous driving vehicle that a user boards; and an abnormal event check device that checks whether or not an abnormal event exists in a passenger room of the autonomous driving vehicle after the user gets off. The autonomous driving vehicle uses a passenger room monitor to acquire, as a comparison-target image, an image of the passenger room after the user gets off the autonomous driving vehicle. The abnormal event check device: acquires a reference image being an image of the passenger room before the user boards the autonomous driving vehicle; acquires the comparison-target image; compares the comparison-target image with the reference image to determine whether or not the abnormal event exists; and notifies the user terminal or a management center, when it is determined that the abnormal event exists.

  • Publication number: 20190129420
    Abstract: An autonomous driving vehicle provides a driverless transportation service for a user. An alarming phenomenon is a natural phenomenon that potentially causes a disaster. The autonomous driving vehicle recognizes, based on driving environment information, the alarming phenomenon at a current location of the autonomous driving vehicle or on a planned travel route from the current location to a destination. When recognizing the alarming phenomenon, the autonomous driving vehicle determines whether to continue or halt vehicle travel control in accordance with a current travel plan. When determining to halt the vehicle travel control in accordance with the current travel plan, the autonomous driving vehicle sets an emergency plan depending on a type of the alarming phenomenon and controls the autonomous driving vehicle in accordance with the emergency plan.
