MOTOR VEHICLE WITH A COOLING ARRANGEMENT FOR A BLACK PRESSURE INDICATOR SYSTEM

Description

[0001] The invention relates to a motor vehicle with an arrangement, wherein the arrangement is located in the area of ​​the vehicle's instrument panel. A black-print display system is a display system for showing information to a motor vehicle occupant, in particular the driver and passenger, in the simplest way by means of reflections. Here, at least a portion of the black-print surface can be illuminated by means of a display unit, such as a screen or tablet. The black-print surface has a reflective property, which is produced, for example, by a reflective surface, so that the generated images are directed towards the driver and / or passenger by means of reflection, i.e., by the image being reflected by the display unit.

[0002] In motor vehicles, air conditioning systems, heating devices, ventilation devices and / or air conditioning devices, such as those known from EP 1 481 825 A1 and DE 60 204 006 496 T2, are used to adjust the climate or room climate or temperature in the passenger compartment of the motor vehicle.

[0003] US Patent 2020 / 171912 A1 discloses a head-up display (HUD) for use on a movable body comprising a windshield, an air conditioning unit with an air outlet, and an exhaust outlet. The HUD includes a light source that emits display light and a beam path housing that defines a beam path for the display light. The display light reaches the windshield, and the information is projected onto the windshield. The HUD also includes an air conditioning duct that defines an airflow path. The light source is exposed to the airflow and radiates heat into it. The housing of the optical path and the air conditioning duct typically contain a partition that separates the airflow path and the optical path.

[0004] Furthermore, US Patent 2019 / 182994 A1 discloses a system for cooling a head-up display (HUD). A vehicle may contain a HUD, which generates heat and therefore may require cooling. In one example, the disclosed techniques relate to a light-emitting HUD module with a power distribution unit (PGU). The specification may include a heat sink connected to the HUD module to dissipate heat from the PGU by conduction and convection. The techniques may also include a heating, ventilation, and air conditioning (HVAC) duct with an outlet to direct airflow from the HVAC duct to the heat sink.

[0005] Furthermore, EP 0 508 323 A1 discloses a head-up display type automotive indicator device that allows for free selection of the turn signal setting and provides good long-range visibility. The display is integrated into the dashboard. An opening is provided in the upper section of the dashboard through which light from the indicator can pass and be reflected off the windshield to the driver's point of view. A transparent front panel is positioned between the display and the opening. Additionally, a defroster duct is located within the dashboard. The opening also serves as the defroster duct's outlet. When the defroster switch is activated, air flows through the duct and rises along the front panel to be blown through the opening in the dashboard onto the windshield.

[0006] One object of the present invention is to prevent overheating of a black print display system.

[0007] This problem is solved by a motor vehicle according to independent claim 1. Meaningful further developments arise from the dependent claims.

[0008] An arrangement located in a section of the instrument panel of a motor vehicle according to the invention enables efficient and, in particular, automated cooling of the black-printed display system. This cooling system can cool sections and / or components of the black-printed display system. This is achieved by means of an airflow for heat dissipation and cooling. The cooling system can adjust the cooling of the black-printed display system based on its current operating state. This prevents overheating of the black-printed display system, thereby increasing its service life and, in particular, reducing downtime.

[0009] For example, the cooling system can be used to generate the airflow and direct it towards a specific area of ​​the black print display system that needs to be cooled.

[0010] For example, the airflow could be a cold airflow or cooling air. In this case, the airflow has a temperature or temperature range such that it can dissipate heat from the black print display system, thereby cooling it.

[0011] For example, the airflow can have a temperature between -5°C and 20°C, particularly in the range between 8°C and 15°C.

[0012] In its intended use or integration into a motor vehicle, the cooling system can be used to perform automated, and in particular system-monitored, cooling of the black-print display system.

[0013] In other words, the cleaning device can be described as a black print display system cooling system.

[0014] The cooling system can, in turn, include a corresponding monitoring and control unit. This unit can detect the operating status of the black-print display system and, depending on the current situation, initiate an appropriate cooling process, particularly an automated one. The cooling system utilizes an airflow, which it generates. This airflow, generated, for example, by a blower or fan unit, cools the display unit, the black-print surface, and / or other components of the black-print display system. This is particularly advantageous for the operation of the black-print display system, as high temperatures can impair its performance.

[0015] For example, the black-print display system can be referred to as a "black-print display" system. The display unit itself can also be designed as a black-print display.

[0016] The cooling system can be an electrical, mechanical, or electromechanical device.

[0017] The arrangement is designed to include at least one cooling channel for providing the airflow, with the at least one cooling channel being located at least partially on the display unit. Depending on the design of the black-print display system and, in particular, depending on the installation situation of the arrangement in a motor vehicle, one or more cooling channels may be provided.

[0018] For example, the cooling duct can be referred to as an air duct.

[0019] The cooling system may be a ventilation duct for air distribution. Accordingly, the arrangement includes an air guidance system to direct or steer the airflow for cleaning the black-print display system.

[0020] The at least one cooling channel can be arranged at least partially, and in particular completely, on the display unit. This means that the cooling channel is, for example, adjacent to the display unit, i.e., in contact with it. This saves space and allows for a direct, and in particular targeted, supply of airflow for cleaning the display unit. Specifically, the at least one cooling channel can be arranged in an area around the display unit.

[0021] In one embodiment, the at least one cooling channel has an air outlet device, which has at least one air outlet directed towards the display unit and / or the black print surface. In particular, the air outlet device can have multiple air outlets, depending on the configuration of the arrangement and especially on the configuration of the black print display system.

[0022] For example, each component of the black-print display system can have an air outlet containing at least one cooling channel. This allows cooling to be implemented at various points within the black-print display system. The air outlet(s) can be positioned within the cooling channel to direct airflow towards the display unit and / or the black-print surface, thus ensuring a focused airflow for cooling.

[0023] In one embodiment, the arrangement includes a control device for controlling the air outlet, thereby allowing the air outlet direction of at least one air outlet to be adjusted. This enables targeted airflow direction, particularly to direct the airflow precisely to areas with elevated temperatures within the black pressure display system.

[0024] With the aid of the control device, which can be described, for example, as an electronic control unit, targeted cooling of a specific area or component of the black-print display system is possible. For example, at least one air outlet can have a louver whose orientation or position can be adjusted or changed by the air outlet mechanism controlled by the control unit. This allows the air outlet direction to be specifically adjusted to cool the black-print display system depending on the situation.

[0025] In one embodiment, the arrangement includes a sensor unit for detecting the operating state of the black-print display system, whereby the operating state is the temperature of the black-print display system. The sensor unit, or detector unit, can be described as an electronic or sensory detection unit, which, for example, comprises several individual sub-sensors that can be arranged in various areas of the black-print display system. Thus, temperature or operating temperature can be monitored or detected in all areas of the black-print display system.

[0026] In particular, depending on its condition, the sensor unit can control the cooling system and especially the control unit in order to carry out a targeted cooling process accordingly.

[0027] The arrangement installed in the vehicle allows information to be displayed to the vehicle occupants in the simplest way possible, within their field of vision. Furthermore, this arrangement enables automated, and especially continuous, cooling of the black-printed display system, ensuring its efficient operation. This automated and, in particular, continuous cooling of the black-printed display system significantly extends its lifespan by reducing the need for failures, repairs, and maintenance.

[0028] It is provided that at least one cooling channel extends longitudinally with respect to a transverse axis of the vehicle in an area between the instrument panel and the windshield of the motor vehicle. In other words, the cooling channel extends in an area at the base of the windshield, such that the cooling channel is located on a side or area of ​​the windshield facing the underbody of the motor vehicle. In particular, the cooling channel is arranged so that it is not visible to the occupants of the motor vehicle.

[0029] The cooling channel can extend at least partially, and in particular completely, along the vehicle's transverse axis. This area can therefore be one where the instrument panel or cockpit and the windshield of the vehicle are in contact. This arrangement ensures that all components of the black-printed display system can be cooled.

[0030] In one embodiment, the arrangement includes a windshield defrosting device with at least one additional air outlet directed towards the windshield. This allows the arrangement, and in particular the air duct, to be equipped with an additional function, enabling both the cleaning of the black-printed display system and the defrosting of the windshield via a cooling duct located between the instrument panel and the windshield. For example, the same airflow can be used for both cleaning and windshield defrosting. In this case, the airflow can be generated in such a way that it can be used for both applications. This can be achieved, for instance, by adjusting the velocity at which the airflow is blown out of an air outlet.Furthermore, the temperature of the airflow can be adjusted accordingly so that it is sufficiently prepared for defrosting the windshield.

[0031] Furthermore, it is conceivable that a control unit could be used to control an airflow generation unit, such as a blower unit, according to the specific application. This would allow for the generation of a customized airflow for cleaning the black-printed display system. Similarly, a separate, individually generated airflow could be provided for defrosting the windshield. In addition to at least one air outlet for cleaning the black-printed display system, the cooling duct could have at least one further air outlet for the windshield defrosting system. This additional air outlet would be directed to blow an airflow onto the windshield for defrosting purposes.

[0032] Thus, the arrangement, and in particular the cooling channel, advantageously incorporates a cooling concept for cooling the black-printed display system as well as a windshield defrosting concept for clearing the windshield of ice, icing, and / or snow. The windshield defrosting system can also be used when the windshield is fogged up or covered in condensation.

[0033] It is provided that an optical element is arranged on the side of at least one cooling channel facing away from the windshield, with which an image generated by an image generation unit of a head-up display in the vehicle can be projected onto a translucent projection surface in a region of the windshield. In other words, in addition to its use for cooling the black-printed display system of the windshield defroster, the cooling channel can also be used as a component or sub-component of a head-up display. Thus, the arrangement and use of the assembly in the vehicle can reduce the number of components and the installation space required. Therefore, the arrangement according to the invention provides further synergistic effects when used in the vehicle.

[0034] By positioning the optical element on the side of the cooling duct facing away from the windshield, or opposite to it, additional optical elements such as mirrors or lenses for the head-up display can be omitted. This allows for a simpler and, in particular, more space-saving integration of the head-up display into the vehicle. For example, the optical element can be fully or partially integrated into the side of the cooling duct facing away from the windshield. It is also conceivable that the surface of this side of the cooling duct could be specially designed to serve as the optical element for the head-up display.Thus, the cooling duct can be used as a "mirror bank" for the head-up display, so that an image from the head-up display can be projected onto the translucent projection surface in the area of ​​the windshield via the air duct, so that the driver of the vehicle in particular can perceive the image in his field of vision.

[0035] The black printed area and the translucent projection area are separate or distinct areas on the windshield. Specifically, the black printed area and the translucent projection area are spaced apart from each other within the windshield area.

[0036] Another aspect concerns a method for cooling a black-pressure display system of a motor vehicle, wherein the operating state of the black-pressure display system is detected and an airflow is generated depending on this operating state. The generated airflow is directed in such a way that the black-pressure display system is cooled at least partially, and in particular completely. For example, the arrangement and / or the motor vehicle has means to be able to carry out the method just described. With the aid of a sensor unit, the operating state of the black-pressure display system can be continuously detected, so that a cooling process can be automatically initiated or carried out by the system depending on the operating or housing temperature.This involves generating an airflow which can be directed or guided, for example, by means of a cooling duct, in such a way that it is specifically or directed to where overheating of the black pressure display system is present or may occur immediately.

[0037] For use cases or application situations that may arise during the procedure and are not explicitly described here, it may be provided that, according to the procedure, an error message and / or a request for user feedback is issued and / or a default setting and / or a predetermined initial state is set.

[0038] The control device may include a data processing device or a processor unit configured to perform one embodiment of the method. For this purpose, the processor unit may include at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor unit may include program code configured to perform the embodiment of the method when executed by the processor unit. The program code may be stored in a data memory of the processor unit. The processor unit may, for example, be based on at least one circuit board and / or on at least one SoC (System on Chip).

[0039] Further developments of the method may exhibit features already described in connection with further developments of the motor vehicle according to the invention. For this reason, the corresponding further developments of the method are not described again here. The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle.

[0040] Another solution involves a computer-readable storage medium comprising program code that, when executed by a computer or computer network, causes it to execute an embodiment of the method. The storage medium can be provided at least partially as non-volatile data storage (e.g., as flash memory and / or as an SSD - solid state drive) and / or at least partially as volatile data storage (e.g., as RAM - random access memory). The storage medium can be located within the computer or computer network. However, the storage medium can also be operated, for example, as an app store server and / or cloud server on the internet. The computer or computer network can provide a processor circuit with, for example, at least one microprocessor. The program code can be binary code and / or assembly code and / or source code of a programming language (e.g.,...).C) and / or be provided as a program script (e.g. Python).

[0041] The following are exemplary embodiments of the invention described. This is illustrated by: Fig. 1 a schematic representation of a motor vehicle according to the invention and an arrangement which is integrated in the motor vehicle; Fig. 2 a schematic representation of components of the arrangement made of Fig. 1 ; Fig. 3 shows an exemplary installation situation of the arrangement made of Fig. 1 in the area of ​​a motor vehicle's instrument panel; Fig. 4 a schematic sectional view of what is shown. Fig. 3 ; Fig. 5 another exemplary representation of the arrangement made of Fig. 3 ; and Fig. 6 a schematic representation of the arrangement made of Fig. 1 in combination with a head-up display.

[0042] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another and each further develops the invention independently. Therefore, the disclosure is intended to include combinations of features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0043] In the figures, identical reference symbols denote functionally equivalent elements.

[0044] In the Fig. 1 Figure 1 shows a schematic view, particularly from above, of a motor vehicle.

[0045] The motor vehicle 1 can optionally be equipped with an arrangement 2. Thus, the arrangement 2 can be integrated into the motor vehicle 1. The arrangement 2 includes, for example, a black-print display system 3. This black-print display system 3 serves, in particular, to display information or images in the field of vision of a driver and / or passenger of the motor vehicle 1. For this purpose, the black-print display system 3 can have at least one display unit 4 or more such display units. With the aid of the display unit 4, which can be referred to, for example, as a "black-print display," images can be displayed on a black-print surface 5. The black-print surface 5 can be a black-print area.

[0046] To operate the black print display system 3 efficiently, minimizing its failure probability and extending its service life, a cooling system 6 and / or a cleaning device 7 can be provided. The cooling system 6 cools the black print display system 3, preventing it from overheating. The cleaning device 7 cleans the black print display system 3 of dirt, contaminants, dust, grime, or other foreign matter.

[0047] In addition to the black-print display system 3, the cooling system 6 can be part of the arrangement 2. Optionally, the cleaning device 7 can also be part of the arrangement 2. A particularly preferred embodiment of the arrangement 2 is one in which the arrangement 2 comprises the black-print display system 3, the cooling system 6, and the cleaning device 7. Thus, the arrangement 2 allows for more efficient and improved use of the black-print display system 3 in motor vehicles.

[0048] In the Fig. 2 At least one partial view of the arrangement 2 is shown as an example. In this embodiment, the black-print display system 3 can have several, in particular three, display units 4. An airflow 8 can be used to cool and / or clean at least parts of the black-print display system 3. The same airflow 8 can be used for both the cooling system 6 and the cleaning device 7. It is also conceivable that the cooling system 6 and the cleaning device 7 each use their own airflow 8 for cooling and cleaning, respectively. The arrangement 2 can have at least one cooling channel or air channel 9 for directing, guiding, or directing the airflow 8 to a component of the black-print display system 3. It is also conceivable that several cooling channels are provided. As shown in the Fig. 2 As illustrated by way of example, the cooling channel 9 can be arranged such that it is at least partially, and in particular completely, in contact with or arranged against the display unit 4. As shown in the Fig. 2 As can be seen, the display unit 4 and the cooling channel 9 are arranged adjacent to each other. This allows the airflow 8 for cleaning and / or cooling to be directed directly or selectively towards the display unit 4.

[0049] Air duct 9 can also be referred to as or used as a cooling duct. It is also conceivable that both the cooling duct and the air duct are designed as a combined unit. It is equally conceivable that the cooling duct and the air duct are separate ducts of arrangement 2.

[0050] In the following, air duct 9 will also be referred to as cooling duct 9 or vice versa.

[0051] In order to direct the airflow 8 evenly to the components or areas of the black print display system 3 and, in particular, to cool or clean essentially all components and / or areas of the black print display system 3, the cooling duct 9 can have an air outlet device 10 (see Fig. 4 ) exhibit. This can be mechanically and / or electromechanically coupled or connected to at least one air outlet 11. As in the Fig. 2 As can be seen by way of example, the cooling channel 9 can have a large number of air outlets. Thus, the airflow 8 can be directed out or blown out at any point or area of ​​the black pressure display system 3 in order to carry out a cooling and / or cleaning process. For example, the multiple air outlets can be spaced apart from each other. As shown in the Fig. 2 As can be seen by way of example, the air outlets 11 can apply the airflow 8 to the display unit 4 over a surface area in order to achieve the most efficient cooling effect as well as an efficient cleaning process.

[0052] For example, with the aid of the air outlet device, 10 different air outlets 11 can be controlled or adjusted so that some of the air outlets serve to clean and / or cool the display unit 4 and other air outlets serve to cool and / or clean the black printing surface 5. Likewise, further air outlets 11 can be set up or adjusted so that they serve to cool and / or clean other components of the black printing display system 3. For example, the arrangement 2 can be a control unit 12 (compare Fig. 1 ) with which the cooling system 6, the cleaning device 7 and / or the air outlet device 10 can be controlled. With the help of the control unit 12, for example, the air outlet device 10 can be controlled in such a way that a respective air outlet direction can be set or adjusted from each air outlet 11.

[0053] In the Fig. 3 An exemplary installation situation of the arrangement 2 in the motor vehicle 1 is shown. In particular, the arrangement 2 can be arranged or integrated in the area of ​​an instrument panel 13 or a cockpit of the motor vehicle 1. The arrangement 2 can be located in a front area (facing the front of the vehicle) of the instrument panel 13. In particular, the at least one air duct 9 and / or, for example, the display unit 4 can be positioned in relation to a transverse axis 15 of the vehicle (see Figure 1). Fig. 1 ) extend lengthwise into an area 14 between the instrument panel 13 and a windshield 16 of the motor vehicle 1. As in the Fig. 3 As an example, the display unit 4 and the cooling channel or air duct 9 are arranged in an area 14 of the windshield 16, which extends towards the vehicle floor. For example, the area 14 can be an area extending between a window or glass root of the windshield 16 and an area of ​​the instrument panel 13 facing the front of the vehicle.

[0054] In particular, the air duct or cooling duct 9 and the display unit 4 can extend partially or completely along a longitudinal extent or length in relation to the vehicle transverse axis 15.

[0055] In the Fig. 4 Figure 2 shows an exemplary sectional view of the arrangement 2. The display unit 4 is visible, emitting light rays towards the black printed surface 5. At the black printed surface 5, the beam path from the display unit 4 can be directed towards the field of vision of a vehicle occupant by means of reflection. Thus, an image 17, which can be described as a virtual image, can be displayed.

[0056] Furthermore, the cooling channel 11 is shown in cross-section. As in this embodiment, the cooling channel 11 can be subdivided, so that it has several sections. Here, a section 18, which is located in the upper part of the cooling channel 11 when viewed along the vehicle's vertical axis 20, and a section 19, which is located in a lower part of the cooling channel 11 when viewed along the vehicle's vertical axis 20, can be located. For example, to cool the display unit 4, cooling air 21 can flow out as an airflow through the air outlet 11, which in this example is directed towards the vehicle floor when viewed along the vehicle's vertical axis 20.

[0057] Advantageously, the cooling channel or air duct 9 can be expanded in its function and used for further applications. One example of another application is windshield defrosting of the windshield 16. For this purpose, the arrangement 2 can, for example, be a windshield defrosting device 22 (see figure). Fig. 1 ). The cooling duct to the air duct 9 can also be used to direct the airflow 8 towards defrosting the windshield 16. This can be achieved, for example, by means of section 18 of the cooling duct 9. In this section, an airflow 23 can flow, which has a higher temperature than the cooling air 21, compared to section 19. Furthermore, an additional air outlet 24 can be provided in the cooling duct 9 so that this airflow 23 can flow or be blown towards the windshield 16.

[0058] In another embodiment, the cooling channel 9 can be a single unit, i.e., not divided into several parts. In this case, a unit 25 for generating the airflow 8 can be controlled, in particular with the aid of the control device 12, depending on whether a cooling process, a cleaning process, or windshield defrosting is to be carried out. The unit 25 can, for example, be a blower unit. Thus, depending on the application, a customized airflow 8 can be generated and directed accordingly with the aid of the cooling channel 9 and the air outlet device 10.

[0059] In particular, the air duct or cooling duct 9 can provide an airflow 8 to perform a cleaning process, a cooling process and / or a windshield defrosting process. Thus, a combined duct can be provided.

[0060] In the Fig. 5 Figure 14 shows a further schematic view of the arranged air duct 9 and the display unit 4. Air inlets 27 are visible, which supply the air duct or cooling duct 9 with air or the airflow 8. In one possible variant, the cooling duct 9 can be connected to the unit 25 via the air inlets 27.

[0061] Furthermore, it is conceivable that the cooling system 6 and / or the cleaning device 7 and / or the cooling duct 9 are combined or connected to an air conditioning system of the vehicle 1. Thus, the air conditioning system of the vehicle 1 can in turn be used to provide an airflow 8 for the cooling system 6, the cleaning device 7, and the windshield defrosting device 22 for the respective operating process.

[0062] To automatically perform a cleaning and / or cooling process of the black-print display system 3, the arrangement 2 can include a sensor or sensor unit 26. The sensor unit 26 can, for example, detect the operating state and / or contamination status of the black-print display system 3. The operating state indicates, in particular, the operating temperature of the black-print display system 3. If the black-print display system 3 reaches a critical temperature, i.e., overheats, a cooling process can be initiated automatically. The contamination status can be used, for example, to determine whether one or more foreign objects are present on a surface of the black-print display system 3.For example, if it is detected that dust, dirt, deposits, particles and / or grime are present on a surface of the black print display system 3, a cleaning process can be initiated automatically. In this process, the sensor unit 26 can be used to locate the area to be cooled and / or cleaned. This allows for targeted cooling and / or cleaning.

[0063] In the case of the integration of the arrangement 2 with the air conditioning system of the motor vehicle 1, the control unit 12 can be a control device of the air conditioning system.

[0064] For example, a cooling or cleaning process of the black-print display system 3 can be automatically performed at continuous time intervals. For example, a cooling or cleaning process can be automatically performed when the vehicle 1 is switched off or parked, or when the vehicle 1 is started.

[0065] Furthermore, it may be provided that a vehicle occupant of the motor vehicle 1 can manually activate a cooling process and / or cleaning process, for example via a control element in the area of ​​the instrument panel 13.

[0066] Furthermore, it is conceivable that the cooling duct 9 has at least one air outlet for cooling the black print display system 3, at least one air outlet for cleaning the black print display system 3, and at least one air outlet for defrosting the windscreen 16.

[0067] According to the invention, the cooling channel 9 is used as a component or functional unit for a head-up display 28. This is described below in the Fig. 6As explained, to save space, particularly in the area of ​​the instrument panel 13, an optical element 30 can be arranged on a side 29 of the air duct or cooling duct 9 facing away from the windshield 16. The optical element 30 allows an image generated by an image generation unit 31 of the head-up display 28 to be projected onto a translucent projection surface in an area of ​​the windshield 16. This eliminates the need for at least one component, namely the optical element 30, in the head-up display 28, thus saving space. This increases the functionality, flexibility, and versatility of the arrangement 2. The optical element 30 can be a mirror or a lens, which can be applied to side 29, for example, by gluing.It is also conceivable that the optical element 30 is designed as a coating, in particular as a reflective coating. Likewise, the optical element 30 can be described as a mirror coating of the head-up display 28.
