Abstract: The present invention relates to a device and a method for controlling an electrically actuated parking brake. Especially, a tip switch is provided which is movable to adopt a tensioning position, a release position, and a neutral position. For example, when the tip switch is moved by the driver to adopt the tensioning position, the control unit increases a nominal value of the actuating force of the parking brake. By actuating the tip switch, the driver is thus able to determine which actuating force is used to actuate the parking brake.
