US Patent 11485367 Driver monitoring system and driver monitoring method

A driver monitoring system includes an automated driving controller that allows hands-off operation in which a driver releases hands from a steering wheel of a vehicle, and controls an automated steering driving in which the vehicle is automatically steered, and a request notification controller that notifies a hands-on request for prompting the driver of the vehicle to perform a hands-on operation to hold the steering wheel, or a surrounding confirmation request for prompting the driver to perform a surrounding confirmation operation to confirm a surrounding condition. During the automated steering driving, the request notification controller is configured to notify the hands-on request or the surrounding confirmation request again when an elapsed time from notification of the hands-on request or the surrounding confirmation request exceeds a criterion time.
