a control unit configured to
determine, based on a detection result of the head detection sensor, to execute alerting the occupant, setting a speed limit of the vehicle, and changing a reclining angle of the seat,
in response to determining to execute the alerting of the occupant based on the reclining angle and the relative position of the head, cause an alert unit to alert the occupant, wherein the relative position of the head to execute the alerting is based on a height difference between an upper end of the headrest and the head,
in response to determining to execute the setting of the speed limit based on the relative position of the head, cause a speed limit setting unit to set the speed limit, wherein the relative position of the head to execute the setting of the speed limit is based on a height difference between the upper end of the headrest and an eye level of the occupant, and
in response to determining to execute the changing of the reclining angle based on the relative position of the head, cause a reclining angle control unit to control the reclining angle, wherein the relative position of the head to execute the changing of the reclining angle is based on the height difference between the upper end of the headrest and the eye level of the occupant.
