Embodiment Construction

[0027] figure 1 It shows a schematic view from the perspective of the driver of the car, including the front windshield 1 of the car, the instrument panel 2 extending under the front windshield 1, the A-pillar 3 surrounding the front windshield 1 and the A-pillar 3 adjacent to the front windshield 1 side windows4. The shaded positions 5 are respectively distributed adjacent to its lower edge on the front windshield 1 and optionally also on the side windows 4 , and the shaded positions 5 indicate that a light visible to the driver can be displayed in each case at this position. Signal. For displaying the luminous signal, the location 5 can be designed to be luminous itself, for example by inserting a light-emitting diode between two mineral glass layers of the glass of the windshield 1 or side windows 4 or by gluing them on the inside. Alternatively, position 5 can redirect the external light from an external light source to the driver's eyes, for example, by adding a scatter...

Abstract

The invention relates to a driver assistance system for installation in a motor vehicle having a display area, a control unit 12 and a hazard detection unit 13 . From the perspective of the driver of the vehicle, the display area is larger than the main line of sight angle range 8 that can be detected without eye movement, and the control unit 12 is used to display signals at different positions 5 in the display area, the The hazard detection unit 13 is used to detect the direction in which the hazard source 7 outside the vehicle is located, at least from the perspective of the driver. The control unit 12 is configured to firstly display a start signal at a position corresponding to the priority direction from the driver's perspective in the event of a detection of a source of danger 7, and then to display at least one first subsequent signal at a position corresponding to an intermediate direction, The intermediate direction lies between the priority direction and the direction in which the source of danger 7 is located. The angular separation between the priority direction and the direction of the first subsequent signal is smaller than the main line of sight angular range 8 , preferably less than half of the main line of sight angular range 8 .

Description

technical field [0001] The invention relates to a driver assistance system which assists the driver of a motor vehicle with regard to the rapid detection and assessment of dangerous situations. Background technique [0002] Although a person can detect a larger field of view through the rotation of his eyes, as long as the eyes are not moving, only information from a smaller portion of the field of view may actually enter consciousness. This part is referred to here as the main field of view and extends azimuthally at an angle of typically 40°. When the driver fixes his line of sight to an object, such as a traffic sign that he wants to read, then it is no longer possible to guarantee the possibility of perceiving outside this main field of view, that is to say, an angular interval greater than 20° from the object of gaze. source of danger. [0003] From the patent document DE 10 2007 045 932 A1, a driver assistance system is known, which can at least detect the direction ...
