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.
