Notification management method for a vehicle-based human-machine interface having at least one notification channel (1.1, ..., 1.5), a notification management system forwarding a notification (4.1, ..., 4.4) directed to at least one vehicle occupant and/or to a vehicle function module to the notification channel (1.1, ..., 1.5) depending on a priority associated with the notification or withholding the notification (4.1, ..., 4.4); - the priority associated with the notification (4.1, ...,4.4) being fixed by a priority number (5.1, ...,5.6); - the notification (4.1, ..., 4.4) then being selected and forwarded to the notification channel (1.1, ..., 1.5) if its priority number (5.1, ..., 5.6) exceeds a channel threshold value (6.1, ..., 6.5) assigned to the notification channel (1.1, ..., 1.5) and it has the highest priority number (5.1, ..., 5.6) for the relevant notification channel (1.1, ..., 1.5); and - the channel threshold value being time-variable and being set in a normal operating mode by the notification management system at predetermined time intervals on the basis of driving data and/or vehicle environment data and/or vehicle data and/or status data of the human-machine interface and/or at least one previous notification transmission and/or vehicle occupant observation data between a minimum threshold value and a maximum threshold value , characterized in that the notification management system for a human-machine interface having a plurality of notification channels (1.1, ..., 1.5) sets a separate, time-variable channel threshold value (6.1, ..., 6.5) for each of the notification channels (1.1, ..., 1.5), and a separate priority number (5.1, ..., 5.6) is assigned to a notification (4.1, ..., 4.4) for at least two of the notification channels (1.1, ..., 1.5); and a change in the channel threshold value of a first notification channel (1.1, ..., 1.5) causes the channel threshold value (6.1, ..., 6.5) of at least one second notification channel (1.1, ..., 1.5) to change. - the priority associated with the notification (4.1, ...,4.4) being fixed by a priority number (5.1, ...,5.6); - the notification (4.1, ..., 4.4) then being selected and forwarded to the notification channel (1.1, ..., 1.5) if its priority number (5.1, ..., 5.6) exceeds a channel threshold value (6.1, ..., 6.5) assigned to the notification channel (1.1, ..., 1.5) and it has the highest priority number (5.1, ..., 5.6) for the relevant notification channel (1.1, ..., 1.5); and - the channel threshold value being time-variable and being set in a normal operating mode by the notification management system at predetermined time intervals on the basis of driving data and/or vehicle environment data and/or vehicle data and/or status data of the human-machine interface and/or at least one previous notification transmission and/or vehicle occupant observation data between a minimum threshold value and a maximum threshold value , characterized in that the notification management system for a human-machine interface having a plurality of notification channels (1.1, ..., 1.5) sets a separate, time-variable channel threshold value (6.1, ..., 6.5) for each of the notification channels (1.1, ..., 1.5), and a separate priority number (5.1, ..., 5.6) is assigned to a notification (4.1, ..., 4.4) for at least two of the notification channels (1.1, ..., 1.5); and a change in the channel threshold value of a first notification channel (1.1, ..., 1.5) causes the channel threshold value (6.1, ..., 6.5) of at least one second notification channel (1.1, ..., 1.5) to change. <EOS>
