  • Driver's physical condition detection device and method
    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.
    Type: Grant
    Filed: August 22, 2017
    Date of Patent: March 17, 2020

  • Driving assistance device
    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.
