1. A control unit for controlling operation of a filter apparatus to collect and to store brake particles produced by a friction brake, comprising:
the control unit, which is configured to execute instructions to cause the filter apparatus to:
determine at least one boundary condition that makes it possible and/or permissible to carry out a regeneration of the filter apparatus, wherein the at least one boundary condition comprises a threshold of a level of moisture in an area surrounding the filter apparatus; and
in response to the determining, cause brake particles stored in the filter apparatus to be removed from the filter apparatus.
