In 1 is an exemplary embodiment of an illustration of a device according to the invention for displaying information on a display unit 1 shown in a vehicle, not shown.

In this case, the information is in particular via detection units not shown in detail and / or sensors which are arranged on the vehicle, determined. The sensors and / or detection units are, for example, distance sensors, radar sensors, an omnidirectional camera and / or CCD cameras and transceiver units of a vehicle-to-vehicle communication and / or other suitable devices and / or transmission means, such as a C2C connection which detect and monitor a surrounding area, in particular a traffic situation in the surrounding area of the vehicle, or transmit information of the surrounding area.

through the detection units is z. As an intrusion and / or presence an object in the respective environment area identifiable as well as a distance of the identified object to the vehicle can be determined. The sensors and the detection units are in an advantageous manner Part of a driver assistance and / or driver information system. Furthermore, it is possible to provide traffic-related information like more environmental information, via a satellite Navigation system and / or via communication channels to receive in the vehicle.

According to the invention, the information determined via the detection units is on the display unit 1 by spatially coded display elements in particular in the correct position displayed. The arrangement of the display elements is shown in the correct position according to the respective ranges and / or orientations of the detection units. That is, determined forward, backward, and lateral traffic situations, and instantaneous forward, backward, and / or lateral directional driveability, and information about it with direction and / or distance to the subject vehicle on the display unit 1 can be displayed. Also, the display unit 1 be formed of a combination of spatially encoded and not spatially encoded display elements, the information can be issued according to partially correct position or not in the correct position.

Conveniently, several display elements form at least one segment 2 to 9 the display unit 1 , Every segment 2 to 9 At least one vehicle-own driver assistance and / or driver information system and / or an environmental information is spatially assigned. For this purpose, a classification of the spatially coded display elements, in particular the segments 2 to 9 in near-vehicle and vehicle-distant information and / or driver assistance and / or driver information systems vornehmbar.

For example, in a partial area A of the display unit 1 a vehicle contour 10 or another suitable character, e.g. As a symbol, or image or a current camera image can be graphically displayed. Usually the background color is black. Alternatively, the background color can be varied.

The display of the segments 2 to 9 can also be used in existing representations in the vehicle, such. B. in which a parking assistance system, be integrated. This can be the segment 2 to 9 be movably output, for example, to support a parking operation and display the respective distances to parking space limiting vehicles and / or obstacles. Also, instead of a segment 2 to 9 a character, in particular a value or a state are displayed. For example, a parameter of a road surface, for. As a μ value, by a value display and / or a corresponding background color or by a corresponding color between the segments and the vehicle contour 10 , are issued.

A driver receives during operation of the device and thus the display unit 1 by means of the vehicle contour 10 completely surrounding segments 2 to 9 in a simple manner by activation, in particular insertion of single or multiple segments 2 to 9 visual warning signals with directional indication, in which direction to protect the vehicle or to support by measures in driving behavior, the driver is informed or warned. Also, the segments can 2 to 9 the vehicle contour 10 only partially surrounded. In addition, fewer or more segments 2 to 9 the vehicle contour 10 surround. Also, the segments can 2 to 9 in a multiple struggle around the vehicle contour 10 be arranged.

The segments 2 to 9 are advantageously presented from the driver, vehicle view and / or from the perspective of the driver assistance and / or driver information system. For example, system names, ie names of the driver assistance and / or driver information systems, are connected to an associated segment for this purpose 2 to 9 displayable. Also, as an alternative or in addition, properties, parameters of the driver assistance system (s) and / or driver information systems and / or information about it and about the current traffic situation identified in the detected environmental area can be determined by means of appropriately controllable segments 2 to 9 be output color and / or alphanumeric and / or graphically and / or changeable.

In one possible embodiment, these form the vehicle contour 10 completely or partially surrounding segments 2 to 9 a ring shape, which is changeable depending on detected information and / or situations. For example, you can segments 2 to 9 in their shape and / or in their distance from the illustrated vehicle contour 10 be varied and spent accordingly. Alternatively or in addition to the annular arrangement of the segments 2 to 9 around the vehicle contour 10 (Also called vehicle silhouette), the shape z. B. oval or angular or circular segment-shaped, for example, to a shape of the vehicle contour 10 corresponding to be executed.

Visual warnings and / or information by means of the expandable and changeable segments 2 to 9 In addition, they can be variably spread over time. In particular, the segments can 2 to 9 be displayed for a predetermined time range, which allows the driver to recognize when and, for example, why a vehicle response was triggered and from which direction the danger came and whether this is possibly extinguished again.

For example, you can use segments shown and hidden 2 to 9 a status and / or a property and / or a parameter of the or the driver assistance, driver information systems or an environment information are displayed. In this case, the or the associated segments becomes or become, for example, when the driver assistance and / or driver information system is switched on 2 to 9 for example, completely illuminated, for example, flat, faded in.

If a system and / or information is not activated, this is or are the associated segments 2 to 9 so reduced (or partially) fade in that, for example, only an outline or shadow of the one or more segments concerned 2 to 9 is visible. The outline may, for example, be shown as a solid or merely dashed line and / or semitransparent line.

In a further possible embodiment, a bar display (not shown) can be displayed in the subarea A. The bar graph illuminates, for example, when the fuel level in the tank is too low, which is detectable via a fill level sensor arranged in the tank, which is part of a driver information system. The bar graph is advantageously spatially coded to the displayed vehicle contour 10 represented. Also, a value, for. As a range or a μ-value of a road surface, are issued.

Because every segment 2 to 9 at least one driver assistance and / or driver information system and / or an environment information assigned and its function and / or properties based on the segments 2 to 9 on the display unit 1 can be represented, the device according to the invention in a simple manner by further segments and / or further subdivisions of the segments 2 to 9 be extended to further driver assistance and / or driver information system and / or other information and / or properties of these in an advantageous manner. For example, further rings, half rings and / or circle segments of other segments around the vehicle contour 10 be issued.

The display unit 1 is particularly preferably designed as a not shown head-up display. The information obtained can be projected onto the windscreen and preferably arranged directly in the field of vision of the vehicle driver. Also, the display unit 1 as another suitable screen unit, z. As an LCD unit, in combination with display elements such. B. LEDs, be formed.

2 shows the display unit 1 with a color highlighted segment 9 , The segments 2 to 9 In addition, at least one color level can be assigned. In this case, the status, a parameter and / or a property of the driver assistance and / or driver information systems, in particular the criticality, and / or of surroundings information and / or vehicle information can be displayed in an optically highlighted color.

In particular, the segments can 2 to 9 highlighted in color or varying in color (= color gradients). For example, for color highlighting the segments 2 to 9 Green, yellow and red issued, which based on the traffic lights different from the environment information derived situations "free ride" or "no danger" (= gray, white or green hue), "possible danger" (= yellow hue) and "acute Symbolize danger "(= red hue). In one possible embodiment, the number of states and / or colors may be limited. By analogy with the traffic light and the restriction to three states or colors, the information transmitted by the display elements, in particular light-emitting diodes, can be detected quickly and intuitively by the vehicle driver. A gray or semitransparent segment 2 to 9 may also indicate the status or state of the driver assistance system or driver information system in question, for example whether this is on (eg white or green color tone) or off (eg gray color tone). Also, other or further suitable shades can be specified and used.

In addition, the shape and / or position of the dispensable or switchable or activatable segments 2 to 9 variable. Alternatively to the color coding of situations can the various states, properties, parameters of the driver assistance and / or driver information systems graphically (eg changeable shape and / or position) and / or optical (eg changeable color tone) and / or acoustically (eg changeable sound signal ) are highlighted. This can be a segment 2 to 9 a switched-on driver assistance and / or driver information system, for example, gray, white or green, a switched off driver assistance and / or driver information system, for example, red and a faulty driver assistance and / or driver information system, for example, red and flashing or red are displayed with a modified form.

In 3 is the vehicle contour 10 with these completely surrounding segments 2 to 9 shown, where the segment 5 is highlighted in color and indicates the direction in which a current situation is to be considered.

In 4 is the highlighted segment 5 additionally shown in the form changed. This was the segment 5 changed from a circular segment into a triangular shape. The segment 5 For example, it is assigned to a driver assistance system for blind spot monitoring. By lighting up and change in the triangular shape of the segment 5 the driver is advised that in the blind spot monitoring the left rear side of the vehicle is a dangerous situation, for example, by an intruding into this area object, z. B. another approaching the own vehicle vehicle.
