Description

[0001] The present invention relates to a motor vehicle. State of the art

[0002] In the field of automotive engineering, the continuous improvement of user experience and safety is a primary focus of development work. The integration of advanced display technologies into motor vehicles plays an increasingly important role in this. These technologies make it possible to display important information directly in the driver's field of vision, which increases safety and makes operating the vehicle more intuitive.

[0003] A key element of modern vehicle displays is the windshield, which not only serves as physical protection but also as a platform for displaying driving information. With the introduction of head-up displays (HUDs), critical data such as speed, navigation instructions, and traffic information are projected directly into the driver's field of vision, reducing the need to take their eyes off the road.

[0004] Electrochromic glass technology has also found its way into automotive engineering. This type of glass can electronically control its transparency, making it possible to vary the light transmission of the windows as needed. This is particularly useful for reducing glare or increasing privacy.

[0005] Recently, micro-LED technology has made significant progress. Micro-LEDs offer considerable advantages over conventional LED displays, including higher brightness, improved energy efficiency, and a longer lifespan. These characteristics make them particularly suitable for use in vehicle displays, where reliability and efficiency are crucial.

[0006] The integration of cameras and sensors to detect the vehicle's surroundings is also an important aspect of modern vehicle technology.

[0007] Rear-view cameras that capture an image of the area behind the vehicle are now standard in many vehicle models. The combination of these technologies with display systems enables a comprehensive and intuitive view of the vehicle's surroundings, which increases safety, especially when reversing.

[0008] DE 10 2022 126 685 A1 and DE 10 2019 210 719 B4 each disclose the subject matter of the preamble of claim 1.

[0009] US10532634B2 discloses a motor vehicle with a main windshield and an additional pane arranged below the main windshield, wherein the additional pane is changeable from a transparent state to an opaque, tinted state. In the opaque state, the additional pane serves as a projection surface for a projector.

[0010] From US20180334101A1, a motor vehicle is known which has a display in the area of ​​the windshield.

[0011] From DE202021000166U1 it is known that a windshield is designed as switchable glass and serves as a projection surface for a projector. When the windshield serves as a projection surface, it is frosted.

[0012] DE102017204168A1 discloses a motor vehicle with multiple cameras for vehicle environment detection, wherein the camera signals are fused together.

[0013] From DE102022129115B3 a motor vehicle is also known which has several cameras for recording a rear area, whereby the camera information is combined with each other.

[0014] DE102018123820A1 also describes a motor vehicle with several cameras for vehicle environment detection, wherein the image data of the cameras are processed in such a way as to generate images on a rearview mirror designed as a screen. Disclosure of the invention

[0015] One challenge remains the efficient and safe transmission of information to the driver while simultaneously ensuring optimal visibility and minimal distraction. Despite the availability of advanced display technologies such as head-up displays and electrochromic glass, designed to enhance driving safety and improve information processing, specific problems persist that have not yet been fully resolved.

[0016] First, integrating display systems into the windshield often involves compromises in visibility through the glass. Traditional head-up displays can be difficult to see under certain lighting conditions or require special surface coatings, which in turn can impair the clear view through the windshield.

[0017] Secondly, while the use of electrochromic glass is an effective method for regulating light transmission, current implementations are often slow in their response time and offer only limited control over the degree of darkening. This can lead to inconvenience and potential safety risks in rapidly changing light conditions, such as those frequently encountered while driving.

[0018] Thirdly, existing systems for displaying information on windshields are often unable to dynamically adapt to changing environmental conditions and the specific needs of the driver. This applies to both the content and the manner of presentation, which are often not intuitive enough to ensure quick and effective information processing.

[0019] Fourth, installing additional display elements such as screens or projectors in a vehicle often increases space and weight requirements, which can negatively impact vehicle dynamics and fuel consumption. Integrating these elements harmoniously and functionally into the vehicle interior without compromising ergonomics presents a further challenge.

[0020] The underlying problem addressed by the present invention is therefore the creation of an integrated display system that enables effective, adaptive, and visually optimized information presentation without obstructing the view or compromising the vehicle's design and functionality. This requires an innovative solution that goes beyond currently available technologies and enables a new way of integrating and using display technologies in the vehicle context.

[0021] The problem described is solved by a motor vehicle according to the independent claim.

[0022] The proposed technical solution offers several advantages over the current state of the art. By using a Daytona screen with an integrated display positioned above the windshield, a novel method of information presentation is created that does not obstruct the driver's view through the windshield.

[0023] This arrangement allows important information to be displayed in the driver's upper field of vision without requiring them to take their eyes off the road. Compared to conventional head-up displays, this solution offers a larger display area and improved visibility under varying lighting conditions.

[0024] The use of a projector, specifically an LED or laser projector, to display the image content on the Daytona screen enables a flexible and high-resolution display. Strategic positioning of the projector in the center of the dashboard ensures optimal projection with minimal impact on the interior.

[0025] A particular advantage arises from the combination of the Daytona lens with electrochromic technology. This allows the lens to dynamically adapt to ambient conditions. Its ability to display an opaque white surface not only improves projection quality but also serves as an integrated sun visor. Control of this function via a GPS receiver and electronic compass allows for automated and precise adjustment to the sun's position, thus increasing driving comfort and safety.

[0026] The integration of a rear-view camera and the ability to continuously display the image on the Daytona windscreen represent a significant improvement over traditional rear-view mirrors. This feature expands the driver's field of vision and increases safety when reversing and in complex traffic situations.

[0027] Overall, this technical solution helps to optimize information display in the vehicle, increase safety, and simultaneously improve the vehicle interior design. It effectively addresses the challenges of information delivery and visibility improvement that existed with previous state-of-the-art technology.

[0028] Further advantageous embodiments of the invention are specified in the dependent patent claims. Brief description of the drawings Fig. Figure 1 shows a top view of a motor vehicle according to the invention. Fig. Figure 2 shows the interior of the motor vehicle and in particular an LED or laser projector located in the center of the dashboard. Embodiments of the invention

[0029] Fig. Figure 1 shows a top view of a motor vehicle equipped with a Daytona Disc (10). This Daytona Disc (10) is positioned above the windshield and serves as a special display surface for various driving information. The Daytona Disc (10) is electrochromic and can electronically control its transparency to display an opaque white surface when required. This feature allows the Daytona Disc (10) to be used as a projection surface without obstructing the driver's view through the windshield.

[0030] Fig.Figure 2 shows the interior of the vehicle, which features a projector (11) mounted centrally on the dashboard. The projector (11) is directed upwards towards the Daytona screen (10) and serves to project various image content onto the Daytona screen (10). The projector (11) can be either an LED projector or a laser projector, both of which provide a clear and high-contrast display of the information.

[0031] The Daytona screen (10) is designed to optionally display an opaque white surface to optimize projection quality. This is made possible by the Daytona screen's (10) electrochromic function, which allows for dynamic adjustment of light transmission. This function is controlled by a GPS receiver and an electronic compass integrated into the vehicle. These systems enable the Daytona screen (10) to be automatically darkened to reduce glare from sunlight and improve the readability of the displayed information.

[0032] As an alternative to projection, the Daytona Disc (10) can also feature an integrated screen, implemented as a micro-LED display. This variant offers a particularly clear and bright display of information without compromising the transparency of the Daytona Disc (10) when no information is being shown. The micro-LED display combines high brightness and energy efficiency with a long lifespan, making it ideal for use in vehicles.

[0033] The vehicle is also equipped with a rear-view camera that captures images and continuously displays them on the Daytona screen (10). This allows the Daytona screen (10) to be used as a replacement for the rear-view mirror, providing an enhanced view to the rear. The camera uses a 36:9 sensor, enabling a wide and detailed view of the area behind the vehicle. Reference symbol list 10 Daytona disc 11 Projector
