  • Publication number: 20210016805
    Abstract: A configuration is realized in which driver's biological information is input and a driver's wakefulness degree is evaluated. The wakefulness degree of the driver is evaluated by applying a result of behavior analysis of at least one of an eyeball or a pupil of the driver and a wakefulness state evaluation dictionary specific for the driver. The data processing unit evaluates the wakefulness degree of the driver by using the wakefulness state evaluation dictionary specific for the driver generated as a result of learning processing based on log data of the driver's biological information. Moreover, a return time before the driver is able to start safety manual driving is estimated. A learning device used for estimation processing based on observable information is able to correlate an observable eyeball behavior of the driver and the wakefulness degree by a multidimensional factor by continuously using the learning device.

  • Publication number: 20200385025
    Abstract: An arrangement is realized in which the motion sickness level of an occupant of a vehicle while automatic driving is being carried out is estimated, and in case the sickness level becomes equal to or larger than an existing standard value, a warning is output to prompt the occupant to change to manual driving, making it possible to return to safe manual driving. The detected information from an acceleration sensor is input and the sickness level of an occupant of a vehicle while automatic driving is being carried out is estimated. Furthermore, in case an estimated value and a warning output standard value are compared with each other and the estimated value becomes equal to or larger than the standard value, the outputting of a warning for prompting the occupant to switch from automatic driving to manual driving is executed. Moreover, a learning process based on operation information of an operator after the warning has been output is carried out.

  • Patent number: 10857942
    Abstract: The present technology relates to an image generating device, an image generating method, and a program which are capable of calling attention of a user quickly. An integrating unit integrates a first image and a second image and generates an integrated image. A superimposition executing unit causes an alert mark to be superimposed on the integrated image and generates a superimposed image in a case in which an object shown in the second image is positioned on a farther side than an object shown in the first image. The present technology can be applied to, for example, a Camera Monitor System (CMS) which provides, for example, an image corresponding to an image observed by a side mirror or a rearview mirror or the like.

  • Publication number: 20200283028
    Abstract: A notification controlling unit controls notification for prompting a driver to return to driving. For example, the notification is performed by a sound output, a light output, display of a character or a mark, haptics, or the like. A calculation unit calculates a return delay time period for determining a notification timing on the basis of a state of the driver. For example, the calculation unit calculates a return delay time period in response to an observable evaluation value based on a type of secondary task being executed by the driver and biological activity observable information of the driver. A return delay time period for determining a notification timing is calculated in response to a type of secondary task and biological activity observable information of the driver, so that a more accurate return delay time period can be obtained and notification of driving return to the driver can be performed at an appropriate timing.

  • Publication number: 20200241549
    Abstract: A configuration for calculating a distance and a position of an object included in an image in a direction in which distance measurement by a distance sensor is impossible is achieved. There is included an object distance calculation unit that inputs an imaged image taken by a camera and calculates a distance of an object in the image, and the object distance calculation unit calculates a distance to the object by applying actual size information of the object and image information of an image object included in the imaged image. Moreover, an object position calculation unit calculates an object position using calculation information of the object distance calculation unit and the image information. An object actual size is obtained on the basis of an imaged image in a direction in which distance measurement by the distance sensor is possible.

  • Publication number: 20200139992
    Abstract: The present technique relates to a vehicle controller and a vehicle control method capable of changing from autonomous driving to manual driving more safely. The vehicle controller includes a running control section exercising control over deviating running from normal running of a vehicle at a time of switching a driving mode from an autonomous driving mode to a manual driving mode; and a driving state detection section detecting a reactivity and a degree of awakening of a driver on the basis of a running operation performed by the driver on the control over the deviating running. A detected reactivity and a detected awake state of the driver are used at a time of switching the driving mode from the autonomous driving mode to the manual driving mode by the driver. The present technique is applicable to, for example, a vehicle controller that controls autonomous driving.

  • Patent number: 10632917
    Abstract: In accordance with driving information that is obtained by a driving situation detecting sensor 13 and is related to the driving situation of a vehicle, a display control unit 20 sets the image area to be presented to the driver DR of the vehicle from an image obtained by a peripheral area imaging unit 11 imaging a peripheral area around the vehicle, and, in accordance with the driving situation, controls the visual recognition range in the peripheral area the driver DR can visually recognize from the image presented by a display unit 50 via a mirror 55. When the driving situation is such that the orientation of a cabin differs from the orientation of a trailer portion, for example, the image area to be presented is set so that the outer side of the trailer portion is included in the visual recognition range even though the orientation of the cabin differs from the orientation of the trailer portion. Thus, a desired peripheral area around the vehicle can be readily viewed.

  • Patent number: 10565736
    Abstract: The present disclosure relates to an image processing apparatus and method, a program, and an image processing system that enable detection of a positional and directional shift of a camera while the vehicle is running. An image processing IC performs a calibration process on four cameras, using image signals from the four cameras, sensing information from a sensing chip, and information detected from a drive system unit or the like from a control microcomputer. For example, the image processing calibrates at least the orientations of the cameras disposed at the front and the rear, in accordance with the infinite point in the running background. Using the correction values obtained through the orientation calibration, the image processing IC generates overhead images of the respective cameras.
