1. An alert control system comprising:
a human machine interface control unit configured to
receive a transfer execution signal for transferring driving operation control from an automatic driving electronic control unit, and
control
acquisition of operation information input from a driver, and
information presentation for the driver;
an alert device configured to notify an occupant of information related to transfer of the driving operation control based on first alert control information or second alert control information output by the human machine interface control unit; and
a detector configured to
detect driver information related to a driving state of the driver, and
output the driver information to the human machine interface control unit,
wherein:
the occupant includes the driver,
the human machine interface control unit includes
a main authority transfer processor configured to execute a main authority transfer process of notifying the driver of a control transfer for changing a driving operation by an automatic driving function to a driving operation by the driver,
a preliminary authority transfer processor configured to
execute a process of notifying the driver, in advance, of the control transfer before the control transfer starts, and
a human machine interface controller configured to
generate the first alert control information based on information acquired from the preliminary authority transfer processor or the second alert control information based on information acquired from the main authority transfer processor,
output the first alert control information and the second alert control information to the alert device,
extract a driver response to preliminary authority transfer from the driver information,
the preliminary authority transfer processor includes
an estimator configured to estimate an occurrence of a situation causing the transfer, and
a determiner configured to determine a level of a possibility of the control transfer based on an estimated factor, and
the human machine interface controller further includes a preliminary notification device configured to
generate the first alert control information for notifying the driver in advance of the possibility of the control transfer with a notification mode corresponding to a determined level of the possibility of the control transfer, and
output the first alert control information to the notification device,
wherein
the first alert control information is different from the second alert control information.
