Description

Technical Field

[0001] The invention relates to a method for adjusting a display area of ​​a motor vehicle according to the surroundings. The invention also relates to a motor vehicle having a sensor device, a projection device, and a computer device for carrying out the method. Background Art

[0002] DE 10 2014 217 366 A1 discloses a method for adjusting the brightness of headlights for a motor vehicle, comprising the step of determining a headlight control signal for adjusting the brightness using distance information. In this case, the distance information represents the distance between the vehicle and an object illuminated or illuminable by at least one headlight. This is particularly intended to avoid overexposure of a camera image, thereby producing an objectively and subjectively better camera image.

[0003] In projections from a motor vehicle to the environment, such as from digital headlights or projection devices, the display area is the vehicle's surroundings. However, a disadvantage is that the vehicle's surroundings are rarely as uniformly defined as, for example, a screen. Consequently, the projected image can be distorted, cropped, or otherwise affected, often to the detriment of the user. Summary of the Invention

[0004] The present invention therefore relates to the problem of specifying a method for adjusting a display area of ​​a motor vehicle to the environment, which method overcomes the disadvantages known from the prior art.

[0005] According to the invention, this problem is solved by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0006] The present invention is based on the general concept of providing a method for adjusting a display area of ​​a motor vehicle to its surroundings, wherein possible obstacles in the motor vehicle's surroundings are eliminated and the display area of ​​a projection device is adjusted accordingly. In the method, data about the motor vehicle's surroundings, such as buildings, distances, and possible interference contours, such as obstacles, are first acquired. This data, along with any possible interference contours, is then transmitted from a sensor device to a computer device. In the method, a desired display is projected onto the display area of ​​the motor vehicle using a projection device or a conventional display device. This display area can be located within the motor vehicle's surroundings or, for example, be configured as a head-up display. Based on the environmental data and interference contour data transmitted by the sensor device, the computer device then determines an adjusted display area, in which a projection surface is free of interference contours. This free-of-interference contour projection surface is therefore unaffected by obstacles surrounding the motor vehicle. The computer device then controls the projection device so that the desired display is projected only onto the adjusted display area where the projection surface is free of interference contours. As a result, the driver of the motor vehicle can more easily and effectively perceive the desired display.

[0007] In an advantageous embodiment of the method according to the present invention, the sensor device acquires data about the motor vehicle's surroundings and any interference contour data by means of ultrasound, a camera, radar, and / or lidar, or other systems. This non-exhaustive list already suggests various possibilities for sensor devices for acquiring data about the surroundings and any interference contour data. Distance data, in particular distance data to obstacles, can also be easily and accurately acquired, in particular by means of ultrasound, radar, and / or lidar.

[0008] In another advantageous embodiment of the method according to the present invention, the projection device adjusts the display area with respect to at least one of the following parameters: size, distortion, and / or cropping. This allows the adjusted display area, into which the desired display is projected, to be designed so that the desired display can be presented in this area without disturbing contours and is therefore easily visible to the driver of the motor vehicle. This significantly improves comfort.

[0009] In a particularly preferred embodiment of the method according to the present invention, the computer device stores the acquired environmental data of the motor vehicle, as well as any interference contour data, in a memory. In this case, purely theoretically, it is conceivable that the storage occurs while the motor vehicle is parked, stationary, with the engine stopped, or in similar conditions. Before or, at the latest, during the next activation of the computer device or projection device, the computer device adjusts the desired display based on the stored environmental data or interference contour data to achieve an optimized image.

[0010] The present invention is also based on the general idea of ​​providing a motor vehicle having a sensor device for acquiring data about the motor vehicle's surroundings and any existing interference contours, a projection device for projecting a desired display into a display area in the motor vehicle's surroundings, and a computer device configured to carry out the method described in the preceding paragraphs. With such a motor vehicle, significantly improved recognition of displays projected into the motor vehicle's surroundings can be achieved, since, in particular, obstacles or typical interference contours are hidden, and the desired display can be projected into a display area that is free of interference contours and thus adjusted.

[0011] Further important features and advantages of the invention emerge from the dependent claims, the drawings and the description of the associated figures based on the drawings.

[0012] It is to be understood that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] according to Figure 1 and Figure 2 According to the invention, the motor vehicle 1 comprises a sensor device 2 for acquiring surroundings data of the motor vehicle 1 and any existing interference contour data caused by interference contours 3, and a projection device 4 for projecting a desired display 5 into a display area 6 in the surroundings of the motor vehicle 1. The motor vehicle 1 also comprises a computer device 7 which is designed to process the surroundings data or interference contour data transmitted by the sensor device 2 and to control the projection device 4.

[0022] It is readily apparent that the sensor device 2 or the projection device 4 can also have a plurality of sensor elements or projection elements. In this case, the display area 6 can be located in front of the motor vehicle 1 in the direction of travel, such as Figure 1 a.) to Figure 1 c.), or laterally, as in Figure 2 a.) to Figure 2 c.), or at any other location.

[0023] In this case, the computer device 7 is able to execute the method according to the present invention for adjusting the display area 6 of the motor vehicle 1 according to the environment, wherein environmental data of the motor vehicle 1 and any interference contour data caused by the interference contour 3 are acquired by the sensor device 2 and sent to the computer device 7.

[0024] The projection device 4 typically projects the desired display 5 into a display area 6, wherein the image corresponding to the image is displayed. Figure 1 a.) and Figure 2 This display region 6 of a.) is free of interfering contours, so that no interfering contours 3, such as obstacles, are present in the display region 6. In this case, the projection of the display 5 can be performed without problems in the display region 6.

[0025] However, if an interfering contour 3, such as an obstacle, is present in the display area 6, such as Figure 1 b.) and Figure 2b.), the display 5 can only be presented distortedly. In this case, the computer device 7 determines an adjusted display area 6' (see Figure 1 c.) and Figure 2 c.)) wherein a projection surface free of interfering contours can be achieved, i.e., a display 5 can be presented free of interfering contours. In this case, the computer device 7 controls the projection device 4 in such a way that the desired display 5 is projected only into the adjusted display area 6 ′ when interfering contours 3 are present, thereby making the display 5 significantly easier to recognize or read. For example, the font size can be adjusted.

[0026] In this case, sensor device 2 can acquire data about the environment of motor vehicle 1 and any interference contours according to the present invention by means of ultrasound, a camera, radar, and / or lidar. Projection device 4 adjusts display area 6 with respect to at least one of the following parameters: size, distortion, or cropping. Overall, as a result, display 5 can also appear smaller in adjusted display area 6' than in the undisturbed display area 6, but the adjusted size of display 5 still provides significantly easier recognition or readability.

[0027] The computer device 7 can also store the acquired environmental data of the motor vehicle 1 and any interference contour data in a memory 8. For the sake of clarity, this memory 8 is only Figure 1 b.) and Figure 2 b.). This can occur at a predetermined time, for example, when motor vehicle 1 is parked, stationary, or the engine is stopped. Before or at the latest during the next activation of computer device 7 or projection device 4, computer device 7 adjusts display 5 according to the stored vehicle environment so that the display is only presented in the adjusted display area 6', thereby obtaining an optimized image.

[0028] All in all, the method according to the invention and the motor vehicle 1 according to the invention allow for a relatively easy implementation of an environment-dependent adjustment of the display region 6 , thereby significantly increasing the comfort for the driver of the vehicle 1 .
