  • Publication number: 20210316736
    Abstract: The driver abnormality determination apparatus includes circuitry configured to detect a driver state of a driver of a vehicle, recognize a driving scene of the vehicle based on external environment information, and detect a state of an involuntary function of the driver, detect a state of a base function that serves as the basis of a driving operation by the driver, detect a state of a predictive driving function of the driver, and detect an abnormality of the driver based on the states each of the involuntary function, the base function, the predictive function, and a determination function based on a detection target item.

  • Publication number: 20210316737
    Abstract: A driver abnormality determination apparatus includes circuitry configured to detect a driver state of a driver of a vehicle, detect a driving operation of the driver, detect an exertion level of an involuntary function of the driver based on the driver state, detect an exertion level of a driving function of the driver based on the driving operation; and determine driver abnormality based on the execution level of the involuntary function and the execution level of the driving function. On condition that a function level of one of the execution level of the involuntary function and the execution level of the driving function is equal to or lower than a specified determination criterion, the circuitry is configured to relax a determination criterion for the other function level.

  • Publication number: 20210316738
    Abstract: [Solution] A driver abnormality determination system includes circuitry configured to detect a driving operation of a driver, detect behavior of the driver's head and motion of eyeballs and/or movement of a sightline of the driver, recognize a driving scene in which the vehicle is driven; a memory that stores a sensor table of a relationship between the driving scene and detected values to be used to determine a driver abnormality; and determine the driver abnormality based on the sensor table, the driving scene, the driving operation and the behavior.

  • Patent number: 10588549
    Abstract: A driver's physical condition detection device for detecting a physical condition of a driver driving a vehicle includes a vehicle detector configured to detect a change in motion of the vehicle during driving, a driver detector configured to detect a change in motion of a head of the driver, and a physical condition determination portion configured to perform a determination process of determining whether or not the physical condition of the driver is deteriorated, based on the change in motion of the head of the driver with respect to the change in motion of the vehicle during driving.

  • Patent number: 10338583
    Abstract: Disclosed herein is a technique for providing driving assistance for a driver in such a way as to increase the driver's degree of internal focus on driving if his or her degree of internal focus on driving is estimated to be low when deactivation of autonomous driving is predicted. Examples of such driving assistance include boosting the moving vehicle noise to be heard inside the vehicle's cabin, increasing sensitivity to a change in the vehicle's state responsive to driving operations, providing navigation to a road with features that would entertain the driver through driving, and giving guidance in exemplary driving operations.

  • Patent number: 9855892
    Abstract: When finding the driver distracted from driving (such as looking aside), this system provides driving assistance that enhances his or her motivation to drive by encouraging him or her to drive actively and thereby increase his or her internal focus on driving. Examples of specific driving assistance include giving exemplary driving instructions to the driver, providing him or her with navigation to a road with features that would entertain him or her through driving, and improving sensitivity to any change in the vehicle's state responsive to driving operations. If dangerous driving is sensed while the driving assistance is being provided, driving control may be performed to increase the driver's tension.

  • Patent number: 9849833
    Abstract: When finding the driver distracted from driving (such as looking aside), this system first alerts him or her to the fact to prompt him or her to focus on driving. However, if the driver is still distracted from driving even when alerted, driving assistance are provided for him or her to enhance his or her motivation to drive by encouraging him or her to drive actively and thereby increase his or her internal focus on driving. Examples of specific driving assistance include giving exemplary driving instructions to the driver, providing him or her with navigation to a road with features that would entertain him or her through driving, and improving sensitivity to any change in the vehicle's state responsive to driving operations.

  • Publication number: 20170202501
    Abstract: When finding the driver tensed by his or her increased external focus on driving, this system provides driving assistance that enhances his or her motivation to drive by encouraging him or her to drive actively and increase his or her internal focus on driving. The driving assistance may be provided when he or she has high driving skills, when there are no traffic jams, or when he or she is in good health. Examples of specific driving assistance include giving exemplary driving instructions to the driver, providing him or her with navigation to a road with features that would entertain him or her through driving, and improving sensitivity to any change in the vehicle's state responsive to driving operations.
