An automatic braking operation is triggered even before the brake pedal is actuated, when, as a necessary criterion, the actuating speed (vg) during the throttling back of the accelerator pedal exceeds a trigger threshold value. In order to adapt the trigger threshold value to the driver's behaviour and thus achieve a more reliable separation of necessary and unnecessary triggering of the automatic braking operation, at least one variable representing the driver's driving behaviour is recorded and the trigger threshold value for the automatic braking operation is determined on the basis of this variable.
