The present invention relates to a method (200) for operating an electrically operable parking brake system (100) of a vehicle (104). According to the invention, it is contemplated that a transfer of the electrically operable parking brake system (100) from a released operating state into an applied operating state is initiated and a predeterminable waiting time period is started when the presence of a trigger event is detected which is independent of an operating device (130) provided for manually operating the electrically operable parking brake system (100) and/or used to release the parking brake system (100) when an operating device (130) is faulty. The present invention further relates to a control device for an electrically operable parking brake system.
