An electric-motor-operated parking brake system carries out metered actuation without a force and travel sensor. A control unit initiates a primary tensioning process with observation of the current, and wherein secondary or tertiary tensioning processes with increased brake application force are executed exclusively automatically by the control unit if monitoring of the stationary state during an energization interval detects an undesired vehicle movement.
