The invention relates to a method for controlling active particulate filter regeneration of a particulate filter (20) in a motor vehicle (10), comprising the steps of: starting active particulate filter regeneration when the particulate filter (20) reaches a predetermined threshold; if active particulate filter regeneration is already in progress and the motor vehicle (10) is traveling in one direction on a multi-lane road (40, 42, 46) within a built-up area; checking which of the lanes (40, 42, 46) is furthest from the largest crowd (50) or an infrastructure area for
pedestrian traffic and / or
pedestrian access; and then autonomously or semi-autonomously changing to this lane (40), or at least suggesting it, provided the motor vehicle (10) is not already on this lane (40);If active particulate filter regeneration is not currently being carried out, but becomes necessary, and it is detected that there is a crowd of people, an infrastructure area for passenger traffic and / or a gathering of people, or a traffic jam within a predetermined distance along the currently traveled
route: suppress active particulate filter regeneration until the crowd of people, the infrastructure area for passenger traffic and / or a gathering of people, or the traffic jam has been passed, or determine an alternative
route that bypasses the crowd of people, the infrastructure area for passenger traffic and / or a gathering of people, or the traffic jam, whereby active particulate filter regeneration is started when the motor vehicle (10) travels on the determined alternative
route. Furthermore, the invention relates to a
system (30) for carrying out such a method and to a motor vehicle (10) with such a
system (30).
