A notification control device is configured to, when the number of objects requiring attention present in surroundings of a vehicle is less than or equal to a predetermined number, respectively set virtual planes on which the objects are projected at positions of the objects so as to face the vehicle and notify a driver to inform him or her of the presence of an object requiring attention if the field of vision of the driver does not overlap a projected location of the object on the virtual plane during a predetermined period from when detecting that object for greater than or equal to a predetermined recognition judgment time, and, when the number of the objects is larger than the predetermined number, not notify the driver in that way.

Notification control device and notification control method

A notification device detecting a predetermined action of a driver of a vehicle in which travel is controlled by an autonomous driving system from a driver image including a face region representing a face of the driver and outputting a confidence rate indicating a certainty in the detection, specifying a message for inhibiting a control ending action which possibly follows the detected action and corresponds to an ending condition of control by the autonomous driving system, and notifying the driver of the specified message through an output device when an effectiveness level is higher than a predetermined notification threshold, the effectiveness level calculated by multiplying the confidence rate by a first probability of the control ending action being inhibited when notifying the driver of the specified message or by a second probability of the control ending action being performed when not notifying the driver of the specified message.

Notification device and notification method

With reference to a message table associating a plurality of messages to be notified to a driver of a vehicle with a first condition, a second condition, last notification time of the message, and renotification requirement, a notification device selects messages associated with an identified first condition corresponding to a situation of surroundings of a vehicle or a state of a driver, selects, from among the messages associated with the identified first condition, messages associated with an identified second condition corresponding to a state of the driver, specifies, from among the messages associated with the identified second condition, a message without a record of last notification time or a message with a record of last notification time and with a renotification requirement requiring a renotification, and notifies the specified message to the driver through an output device.
