Estimating (Ma) for the visual detection area, comprising: calculating means (11) for the visual recognition area, a visual recognition area (V, Va, Vb, V (T)) based on a world coordinate system, which through a driver (D) is detected, on the basis of at least the eyes of the the driver (D), and calculates a position of a vehicle, and a Warngradeinstelleinrichtung (12) having a warning level (w) of the driver (D) with respect to a plurality of visual recognition areas (V, Va, Vb, V (T)) which is calculated from the past up to the present for the predetermined time are, for each of the plurality of visual recognition areas (V, Va, Vb, V (T)) is established, and estimating means (14) of the visual recognition area in the time series, the visual recognition area (V, Va, Vb, V (T)) of the time series as a region defined by the driver (D) is currently being recognized, on the basis of history of a plurality of detection areas (V (T)), which are calculated from the past up to the present for a predetermined time, estimates, wherein the Warngradeinstelleinrichtung (12) sets the warning level (w) smaller as the time (T) of the driver (D), of the visual recognition area (V, Va, Vb, V (T)) recognizes older.
