DISPLAY CONTROL METHOD, DISPLAY SYSTEM FOR A FRONT WINDSHIELD OF A VEHICLE, AND VEHICLE

FIELD OF THE DISCLOSURE
The present disclosure relates to the field of control technology related to vehicles, and more specifically to a display control method for a front windshield of a vehicle, a display system for a front windshield of a vehicle, a vehicle including the display system for a front windshield of a vehicle, a computer readable storage medium, and a computer program product.

BACKGROUND

With the formation of the development trend of automotive intelligence, the demand for interaction between people and vehicles is increasing day by day. In the process of interacting between people and vehicles, information interaction is particularly important. Therefore, for intelligent vehicles, the demand for more display areas is increasing day by day, which can provide more informational supports for the drivers and passengers of the vehicle.
In the existing technical solutions for in-vehicle information display, advertising information can be displayed on vehicles such as rear windshields. However, such method of information display is relatively fixed, and basically only pre-recorded advertisements can be displayed in the entire rear windshield area. This display solution is not ideal for the front windshield.

SUMMARY

In the prior art, for example, in the technical solution for displaying advertisements on the rear windshield, it is necessary to use the entire rear windshield as the display area. However, if all area of the entire front windshield is used as the display area, the front windshield will affect the driver's observation of road conditions, which will inevitably bring danger to driving safety.
For the aforementioned technical issues, the inventor of the present disclosure proposes to partition the front windshield to add information display functions into some areas of the front windshield without affecting driving safety, thereby improving the driving experience of drivers and/or riding experience of passengers.
Specifically, a first aspect of the present disclosure discloses a display control method for a front windshield of a vehicle comprising:

As mentioned previous, the information display method on the rear windshield in the prior art uses a whole piece of glass for the purpose of information display, while the front windshield cannot be arranged in this way. For such technical status and corresponding technical issues, the inventor of the present disclosure innovatively proposes to partition the front windshield, thereby adding information display functions to some areas of the front windshield without affecting driving safety, thereby improving the driving experience of drivers and/or riding experience of passengers.
In the following a detailed explanation of the technical solution according to the present disclosure is provided according to several embodiments, and firstly a display control method for a front windshield of a vehicle according to the present disclosure will be introduced. Specifically, FIG. 1 illustrates a flowchart of a display control method 100 according to an embodiment of the present disclosure. From FIG. 1, it can be seen that in order to not affect driving safety, the display control method 100 according to an embodiment of the present disclosure will comprise firstly dividing the front windshield into a display area and a non-display area in method step 110, wherein the display area includes a plurality of display sub-areas. Here, the display sub-area refers to a part of the front windshield that can independently complete certain information display functions, which can be completely independent of other display sub-areas, or be made of interconnected materials along with other display sub-areas. Here, division of display area and non-display area can be based on, for example, the results obtained from scientific experiments and/or current and potential implementation laws and regulations. For example, according to the research of the inventor of this disclosure, the area directly in front of the driver needs to be reserved for observing the road conditions ahead to ensure driving safety, so the area directly in front of the driver will usually be divided as a non-display area. Correspondingly, for drivers, the area directly in front of the co-driver seat is not so important for driving safety when the traffic conditions are not complex, so this area can be arranged as a display area.
In addition, after the completion of vehicle manufacturing, the display areas and non-display areas of the front windshield can also be dynamically divided. At this time, for example, according to the driving habits of the specific driver, the attention area of their eyes, namely the eye track, can be counted, so as to display the most important information in the area which they concern most. Such division can be correspondingly arranged for different drivers.
Of course, it is also possible to obtain configuration data for each driver, such as from the internet or other locations, based on which display and non-display areas can be divided. It is also possible to pre-store the configuration data of each driver on the vehicle. After a specific driver gets on the vehicle, the configuration data can be selected based on the image recognition technology or manually selected by the specific driver, and then the display areas and the non-display areas can be divided correspondingly. The specific implementation mentioned above is also applicable to other occupants in the vehicle, such as occupants in the co-driver seat or other occupants.
Then, the display control method 100 will comprise displaying corresponding content in at least one of the plurality of display sub-areas in method step 120. Here, displaying corresponding content in at least one of the plurality of display sub-areas comprises displaying the corresponding content in at least two display sub-areas, displaying the corresponding content in at least three display sub-areas, displaying the corresponding content in at least four display sub-areas, displaying the corresponding content in at least five display sub-areas, displaying the corresponding content in at least six display sub-areas, displaying the corresponding content in at least seven display sub-areas, displaying the corresponding content in at least eight display sub-areas, displaying the corresponding content in at least nine display sub-areas, displaying the corresponding content in at least ten display sub-areas, and displaying the corresponding content in even more display sub-areas. Here, the corresponding content is usually related to driving, and may be related to entertainment, in short, it will be variable information content rather than fixed and unchanging content. For example, after partitioning, driving assistance information such as steering information can be displayed on the driver's side A-pillar, and navigation information can be displayed in the center of the front windshield. Of course, those skilled technical persons should understand that the configuration of other specific content is also feasible and falls within the scope of the claims to be protected by the present disclosure.
Compared with the existing methods of displaying information using a whole piece of glass, the display control method 100 divides the front windshield into a display area and a non-display area in this way, the non-display area is mainly used to ensure the driving safety of drivers, while the display area is used to provide additional information display area to drivers or passengers. In this display area, relevant information for improving driving safety can be displayed to further improve driving safety, and other information can also be displayed to improve the efficiency of information interaction between vehicles and humans, as well as user experience.
In an embodiment according to the present disclosure, displaying the corresponding content in at least one of the plurality of display sub-areas comprises simultaneously displaying the corresponding content in at least two of the plurality of display sub-areas. For example, simultaneously displaying the corresponding content in two display sub-areas, three display sub-areas, four display sub-areas, five display sub-areas, six display sub-areas, seven display sub-areas, eight display sub-areas, nine display sub-areas, ten display sub-areas, or even more display sub-areas. In this way, sufficient display sub-areas can be provided to drivers or passengers in two or more display sub-areas simultaneously to efficiently display information. In addition, due to having two or more display sub-areas working together, it is possible to customize different information display ways for different occupants in the vehicle, such as drivers and passengers to improve user experience. For example, the head up display (HUD) area in front of the driver is used to display driving assistance information to the driver, while the area directly in front of the passenger in the co-driver seat can be used to display entertainment or navigation information to the co-driver seated in the co-driver seat.
In an embodiment according to the present disclosure, the plurality of display sub-areas is physically independent of each other. That is, the plurality of display sub-areas will not overlap with each other, they are located at different positions of the front windshield. However, the inventor of the present disclosure would like to emphasize that the subsequent partition modes and the display sub-areas here are not the same concept. A partition mode can include one or more display sub-areas, so different partition modes can have overlapped display sub-areas. In addition, in specific use, in a partition mode, all of display sub-areas can be non-overlapped physical areas; however, in different partition modes, the display sub-area in the previous partition mode may be overlapped with or be completely physically independent from and non-overlapped with a display sub-area in the subsequent partition mode. In this way, the independence of information display is achieved, which ensures the independence of control, that is, the ability to independently control different display sub-areas without mutual interference; meanwhile also ensures the independence of the display effect, so that the display contents do not overlap to allow viewers to clearly obtain the corresponding information. In addition, it is particularly advantageous to display a plurality of sub-areas simultaneously. Here, the non-display area includes an area of the front windshield located directly in front of the driver.
As for where these display sub-areas are located on the front windshield, the following description will provide non-limiting examples. For example, FIG. 2 illustrates a possible partition scheme primarily for drivers according to the present disclosure, while FIG. 3 illustrates a possible partition scheme primarily for passengers according to the present disclosure. From FIG. 2, it can be seen that for the driver, in this embodiment, there are five areas: Area 1 located at the lower edge of the left side of the front windshield, Area 2 located in the front windshield near the A-pillar on the driver's side of the vehicle, Area 3 located in the center of the front windshield, Area 4 located directly in front of the co-driver seat of the front windshield, and Area 5 located at the upper edge of the front windshield, that is, the area of the front windshield is in front of the sunshade on the driver side. Here, Area 5 can also be located in other areas, such as the front windshield area corresponding to the interior rearview mirror, which is the front windshield area in front of the interior rearview mirror. From FIG. 3, it can be seen that for the occupant in the co-driver seat, in this embodiment, five areas can also be included, namely, Area 1 located at the lower edge of the right side of the front windshield, Area 2 located in the front windshield near the A-pillar on the co-driver side of the vehicle, and Area 3 located directly in front of the co-driver seat of the front windshield, Area 4 located in the center of the front windshield and Area 5 located at the upper edge of the front windshield, that is the front windshield area in front of the sunshade on the passenger side. Here, Area 5 can also be located in other areas, such as the front windshield area corresponding to the interior rearview mirror, which is the front windshield area in front of the interior rearview mirror.
From the above description, it can be seen that different areas can be divided for different persons in the vehicle. In summary, here, the method step 120 of the display control method 100, that is, displaying the corresponding content in at least one of the plurality of display sub-areas can further include displaying the corresponding content at the first sub-area located in the center of the front windshield. Due to the first sub-area (such as Area 3 in FIG. 2 or Area 4 in FIG. 3) being located in the center of the front windshield, the content displayed in the first sub-area can be seen by occupants at various positions in the vehicle, which will improve the information sharing efficiency of the display control method 100 according to the present disclosure. Here, the first sub-area includes the center of the front windshield, which can usually be arranged symmetrically about the center of the front windshield, for example. The specific size can be adapted according to the application scenario, for example, the height is between 20%and 70%of the height of the front windshield, and the width is between 10%and 50%of the width of the front windshield.
The method step 120 of display control method 100, that is displaying the corresponding content in at least one of the plurality of display sub-areas can further include: displaying the content in at least one second sub-area (such as Area 2 in FIG. 2 or Area 2 in FIG. 3) of the front windshield near the A-pillar of the vehicle; displaying the content in the third sub-area (such as Area 4 in FIG. 2 or Area 3 in FIG. 3) directly in front of the co-driver seat of the front windshield; displaying the content in at least one fourth sub-area (such as Area 1 in FIG. 2 or Area 1 in FIG. 3) located at the lower edge of the front windshield; and/or displaying the content in at least one fifth sub-area (such as Area 5 in FIG. 2 or Area 5 in FIG. 3) located at the upper edge of the front windshield. Here, the fourth sub-area and the fifth sub-area can be either a single sub-area connected from left to right, or two sub-areas that are independent and not connected to each other. On the basis of the first sub-area mentioned above (such as Area 3 in FIG. 2 or Area 4 in FIG. 3) , the display sub-area can also include at least one second sub-area of the front windshield near the A-pillar of the vehicle, a third sub-area located directly in front of the co-driver seat of the front windshield, at least one fourth sub-area located at the lower edge of the front windshield and at least one fifth sub-area located at the upper edge of the front windshield, thereby enabling targeted display of corresponding content at each position of the front windshield for an occupant in each seat, which improves the pertinence of information sharing to enable occupants in different positions to receive corresponding information. Alternatively, in this way, the front windshield can be divided into different display sub-areas based on the habits of the occupants inside the vehicle, thereby enabling targeted information display solutions for the occupants inside the vehicle. Of course, it will be apparent to those skilled in the art that such a division method is only exemplary and not restrictive and other division methods will fall within the protection scope of the claims without departing from the invention concept disclosed in the present disclosure.
The possible locations of display sub-areas are shown in conjunction with FIGS. 2 and 3, during the specific display control, for example, the corresponding content can always be displayed at the fourth sub-area (such as Area 1 in FIG. 2) in front of the driver when the vehicle is started. That is, in Area 1 of FIG. 2 in which the driver has a better view, if the corresponding content, such as collision warning, is always displayed to the driver, it will significantly improve driving safety. In addition, the term 'always' here refers to stopping the display of at least one display sub-area when the vehicle is in a starting state and the parameters associated with the vehicle change, which will be described below, which means that if the display of Area 1 in FIG. 2 is turned on, the display of this Area 1 does not need to consider the situation of "stopping" the display when the above parameters change in the future, as long as the vehicle is still in the starting state, it will always be displayed.
In addition, for example, for the driver, for example, the driving speed of the vehicle or warning information for warning of a possible collision with the preceding vehicle can be displayed in Area 1 shown in FIG. 2, and steering information can be displayed in Area 2 to remind the driver whether to turn at the next intersection and which direction to turn, the information related to navigation (such as route display) or automatic driving assistance system is displayed in Area 3, the blind spot reminder information is displayed in Area 4, and the vehicle status information such as vehicle in automatic driving, automatic cruise, manual driving mode, vehicle in courtesy to pedestrians, the taxi is empty or waiting for passengers, etc., is displayed in Area 5. For the occupant in the co-driver seat, for example, the weather information can be displayed in Area 1 as shown in FIG. 3, the destination information can be displayed in Area 2, the information related to video entertainment can be displayed in Area 3 (such as playing a movie) , the information related to navigation (such as displaying a route) or the information related to the autonomous driving assistance system can be displayed in Area 4, the information such as vehicle speed can be displayed in Area 5, for example, . In addition, especially Area 3 in FIG. 2 and Area 4 in FIG. 3 are common areas that can be displayed for the passengers in the rear row (s) .
The above description is an example of the information that may be displayed in each display sub-area, in the specific display, combinations and permutations of the above display sub-areas can be made according to different partition modes. At this time, the concept of partition mode needs to be introduced. Here, the partition mode refers to the working method of selecting at least a part of the display sub-areas that can potentially display information to display. As mentioned earlier, different partition modes can have overlapping display sub-areas or non-overlapping display sub-areas. That is, a display sub-area in a partition mode can partially overlap or even completely overlap with a display sub-area in another partition mode (of course, the two completely overlapping display sub-areas are actually one display sub-area) or can be completely independent of a display sub-area in another partition mode, i.e., there is no overlap. In summary, the display mode of the display area includes at least a first partition mode and a second partition mode, wherein the display sub-areas included in the first partition mode and the display sub-areas included in the second partition mode are not identical. After having partition modes, it is possible to determine which partition mode to be selected based on a plurality of conditions. At this time, the display control method according to the present disclosure also includes selecting the display mode of the display area according to actively determined control instructions or passively received control instructions. That is, the selection of the partition mode can be done proactively, that is, according to actively determined control instructions; can also be done passively, in which case it is necessary to passively receive control commands input by the driver of the vehicle to select the display mode of the display area.
In the following the selection of the display mode, that is, the operations of actively selecting display mode and the passively selecting display mode by the vehicle is described more specifically. For example, it is possible to arrange the display mode according to the seating status of occupants at various positions of the vehicle when in actively selecting a display mode by the vehicle. Specifically, the vehicle can select the display mode for the display area according to the positions of occupants in the vehicle, such as displaying according to the display mode shown in FIG. 2 when there is no passenger in the co-driver seat, and displaying according to the combined display mode (i.e., consisting of Areas 1, 2, 3, 5 in FIG. 2 and Areas 1, 2, 3, and 5 in FIG. 3) shown in FIG. 2 and FIG. 3 when there is a passenger in the co-driver seat. In summary, when there is no occupant sitting in the co-driver seat, the display sub-area corresponding to the first partition mode (such as the display sub-area shown in FIG. 2) is displayed, while when there is an occupant sitting in the co-driver seat, the display sub-area corresponding to the second partition mode (such as the display sub-area shown by combining FIG. 2 and FIG. 3) is displayed, wherein the display sub-area corresponding to the second partition mode includes at least a part of the display sub-area corresponding to the first partition mode. Here, to identify whether there is an occupant sitting in the co-driver seat, for example, it can be achieved by image recognition (such as by using an in-vehicle camera) , or can be determined according to pressure sensors at the co-driver seat of the vehicle. Here, the display sub-area corresponding to the first partition mode and the display sub-area corresponding to the second partition mode can be pre-configured, which is recorded in the vehicle's memory, and read and used from the memory when needed.
Of course, the selection of display mode can also be determined according to other parameters, such as the lighting conditions inside and outside the vehicle, the distance between the vehicle and the front vehicle, and the driver's gaze concentration position (with the help of eye tracking sensors) etc. In summary, when the first parameter is met, it is displayed in the display sub-area corresponding to the first partition mode, while when the first parameter is not met, it is displayed in the display sub-area corresponding to the second partition mode. Here, the display sub-areas included in the first partition mode and the display sub-areas included in the second partition mode are not identical. For example, when the first parameter is that the distance between the current vehicle and the object in front of it (such as the vehicle or pedestrian in front) is greater than or equal to 100 meters, that is, if the distance between the current vehicle and the object in front is greater than or equal to 100 meters, it is usually considered a safe distance, in this case, for example, it can be displayed in a partition mode, such as a display sub-area in front of the passenger in the co-driver seat included to display video entertainment information to them; when the first parameter is not met, that is, when the distance between the current vehicle and the object in front is less than 100 meters, it is necessary to pay more attention to the driver's driving safety, at this time, the display sub-area in front of the passenger in the passenger's seat may no longer be able to display video entertainment information to the passenger in the passenger's seat, and it is necessary to not display any content so that the driver can better observe the road or vehicle conditions ahead through the display sub-area of the front windshield to improve the driving safety, in this case, the first parameter is not met, the display sub-area corresponding to another partition mode which does not include the display sub-area directly in front of the passenger is displayed.
To achieve the first partition mode or the second partition mode mentioned above, it is required to have a display imaging function in the corresponding display sub-area of the front windshield, whether an autonomous display function layer or a projection display function layer.
With such a display mode configuration, in addition to the processing way of the vehicle actively determining a display mode mentioned above, the display mode of the display area can also be selected according to the control instruction received via the vehicle machine interface. When the vehicle has both control modes, the control instructions received via the vehicle machine interface have priority over the actively determined control instructions, that is, if the user of the vehicle does not select a display mode, the display mode is automatically determined by the vehicle, such as selection of a display mode according to the determination of relevant parameters. However, if the user of the vehicle has configured or selected a display mode, the execution of the display mode is achieved according to the configuration or the selection. At this time, it is possible to receive a fixed combination of the predetermined display sub-areas, as well as a flexible combination of the display sub-areas that are completely selected by the user. At this time, the display mode of the display area can also include a third partition mode, and the display control method can display the display sub-area corresponding to the third partition mode according to the control instructions received via the vehicle machine interface. The third partition mode here can be the same or different from the first or second partition modes mentioned above, that is, the display sub-areas included in the third partition mode can be the same as the display sub-areas included in the first partition mode or the display sub-areas included in the second partition mode mentioned above, can also be different from the display sub-areas included in the first partition mode mentioned above or the display sub-areas included in the second partition mode mentioned above. In summary, the control instructions include selecting at least one of the preset display modes in the vehicle or selecting a combination of display sub-areas of the front windshield. For example, the display can be performed according to the display mode selected by the driver which consists of Areas 1 and 2 in FIG. 2 and Areas 3 and 4 in FIG. 3. Here, the display mode consisted of Areas 1 and 2 in FIG. 2 and Areas 3 and 4 in FIG. 3 is only an exemplary description rather than a restrictive description. Those skilled in the art should understand that the selected display mode can also be a display mode consisted of Areas 1, 2, 3, and 4 in FIG. 3, for example. To better display information to passengers at various positions in the vehicle, the display sub-areas included in the first partition mode and the display sub-areas included in the second partition mode can both include a first sub-area located in the center of the front windshield (i.e., Area 3 in FIG. 2 or Area 4 in FIG. 3) . In addition, to improve the possibility of information sharing, the content can be displayed at the first sub-area (such as Area 3 in FIG. 2 or Area 4 in FIG. 3) included in the display sub-area corresponding to the third partition mode, and the first sub-area is located in the center of the front windshield.
In the operation of the specific display control method, to further improve driving safety, for example, it can be considered to stop the display in the area near the left A-pillar for ensuring that the driver has sufficient front windshield area to observe the situation on the left side of the vehicle when determining that the vehicle is turning left; correspondingly, for example, it can be considered to stop the display in the area near the right A-pillar for ensuring that the driver has sufficient front windshield area to observe the situation on the right side of the vehicle when determining that the vehicle is turning to the right.
In addition to displaying the information to the interior of the vehicle, it can also display the information to the exterior of the vehicle. In summary, displaying the corresponding content in at least one of the plurality of display sub-areas further includes: obtaining the traffic condition of the vehicle and displaying the information output by the vehicle to the exterior of the vehicle in at least one display sub-area, preferably in at least two display sub-areas, and more preferably in at least three display sub-areas according to the traffic condition. In other words, in the technical solution of the present disclosure, it is also possible to display the information output by the vehicle to the exterior of the vehicle in at least four display sub-areas, information output by the vehicle to the outside of the vehicle in at least five display sub-areas, in at least six display sub-areas, and in at least seven display sub-areas, in at least eight display sub-areas, in at least nine display sub-areas, in at least ten display sub-areas, and in many more display sub-areas. For example, when there is a zebra crossing on the current side, to inform potential pedestrians to cross the road safely, they can be prompted that the vehicle is performing a courtesy operation or that the current vehicle is in a parked state, the information can be displayed to people outside the vehicle through some of the above areas. For example, the information output by the vehicle to the exterior of the vehicle can be displayed in the second sub-area (such as Area 2 in FIG. 2 or Area 2 in FIG. 3) and/or the fifth sub-area (such as Area 5 in FIG. 2 or Area 5 in FIG. 3) according to the traffic conditions such as a zebra crossing ahead. The information outputted by the vehicle to the exterior of the vehicle may include vehicle driving status information, vehicle speed information, and/or information related to the personnel to be picked up by the vehicle.
The traffic conditions can include other parameters such as whether there are parking signs, and whether the distance from other objects is too close except whether there is a zebra crossing ahead. In summary, the traffic conditions include at least one of the following: whether there is a specific traffic sign in front of the vehicle; whether the signal lights in front of the vehicle have a specific color; and whether there are specific people or pedestrians within a certain range around the vehicle.
At this time, obtaining the traffic conditions of the vehicle further includes obtaining the traffic conditions by means of sensors arranged on the vehicle. During specific execution, obtaining the traffic conditions of the vehicle further includes: measuring the distance between the target object and the vehicle by means of a distance detection unit; alternatively, determining the traffic conditions by means of image recognition technology. Specifically, for example, the distance measurement is implemented using the distance detection unit to emit light waves, ultrasonic waves, electromagnetic waves, or other distance detection signals for distance detection towards the target object. For example, during the driving process of a vehicle, to prevent collisions, Attention will be paid to whether there are obstacles in front of the vehicle, at this time, for example, infrared technology can be used to perceive the direction of objects with body temperature in front of the vehicle, usually animals, including humans and other living creatures such as pets, then the distance between the front of the vehicle and the target object in front of the vehicle such as pedestrians or cyclists is measured using a distance detection unit based on that direction. Of course, those skilled in the art should understand that the recognition of the target object can also be implemented by other technologies such as image recognition technology. The specific details of image recognition technology will not be elaborated here. In addition, the image recognition technology can also be used to identify specific traffic signs (such as zebra crossings) or specific colors of signal lights, for example, to determine whether the relevant traffic condition has changed.
Preferably, the distance detection unit is arranged on the A-pillar or B-pillar of the vehicle. Of course, those skilled in the art should understand that the distance detection unit can also be arranged in other positions, as long as such setting positions can measure the distance between the target object and the vehicle.
In addition, when the road conditions around the vehicle are complicated, it is necessary to reduce visual signal input and pay more attention to ensuring the view of the driver, at this time, it is possible to select to stop displaying certain areas. In summary, when the display control method according to the present disclosure is executed, the display of at least one display sub-area is stopped when the vehicle is in a start state and the parameters associated with the vehicle change. The parameters associated with the vehicle can be either the parameters of the vehicle itself or changes of the internal or external environment of the vehicle. For example, when there are objects within the first distance range of the vehicle, e.g., there are pedestrians within 5 meters in front of the vehicle, it indicates that the traffic is more complicated and prone to accidents, therefore, it is necessary to stop the display of some sub-areas to improve the driver's visibility and thereby improving driving safety. Specifically, stopping the display of at least one display sub-area when the vehicle is in a starting state and the parameters associated with the vehicle change further includes: stopping the display of the second sub-area near the left A-pillar when determining that the vehicle is turning left; stopping the display of the first sub-area, the second sub-area near the right A-pillar and/or the third sub-area when determining that the vehicle is turning right; stopping the display of the second sub-area near the right A-pillar and/or the fourth sub-area near the lower edge of the front windshield near the co-driver seat when the co-driver seat becomes vacant from being occupied, for example, presence or absence of passengers in the co-driver seat can be detected by a camera in the vehicle or a pressure sensor under the co-driver seat, when using a camera for image recognition, for example, sampling can be done every 1 second or in response to the opening of the passenger side door, but when using a pressure sensor, sampling can be done every 10 seconds or in response to the opening of the passenger side door; and/or stopping the display of the first and third sub-areas when there is an object within the first distance range of the vehicle. Here those skilled in the art should understand that since the vehicle generally move forward, it is possible to focus on whether there are objects within the first distance range in front of the vehicle; of course, since the vehicle may also reverse, correspondingly it is also possible to focus on whether there are objects within the first distance range behind the vehicle. Specifically, when determining the presence of an object within the first distance range of the vehicle, stopping the display of areas such as Areas 3 and 4 in FIG. 2 or Areas 3 and 4 in FIG. 3, additionally, it is also considered stopping the display of areas close to the left and right A-pillars, i.e. at Areas 2 in FIGS. 2 and 3. During specific operation, for example, the object can be identified by means of the image recognition technology, and further preferably, the distance between the object and the vehicle can be determined by means of the image recognition technology. At this time, the depth of field of the corresponding object in the image can be determined using known image recognition techniques, for example, to determine the distance between the object and the vehicle.
For the fifth sub-area located at the upper edge of the front windshield, i.e. Areas 5 in FIGS. 2 and 3, as there is a sunshade or interior rearview mirror is usually arranged in the internal area corresponding to this position, it is not conducive to displaying information to occupants inside the vehicle, so it can be continuously used for displaying information to the outside of the vehicle, vehicle driving status information (such as whether it is in automatic driving, automatic cruising, manual driving mode, or in courtesy to pedestrians) , vehicle speed information, and/or information related to the personnel waiting to be picked up or picked up by the vehicle can be displayed in the fifth sub-area. In specific implementation, it is more convenient to use an autonomous display function layer, while using a projection display function layer can also be achieved in some cases, for example, it is possible to make the light projected by the projector not directly on the corresponding sunshade or the side of the interior rearview mirror facing the outside of the vehicle, but instead, for example, reflected via the mirror surface, for example, via the mirror surface outside of the windshield and projected onto the upper edge of the front windshield to project and display the information. When displaying the information related to the personnel to be picked up or dropped off by the vehicle, for example, it is possible to identify whether the personnel to be picked up or dropped off is within a certain range of the vehicle by the image recognition technology, a welcome message will be displayed to the personnel to be picked up or dropped off when the above conditions are met, thereby providing a better user experience for the personnel to be picked up or dropped off.
For the area at the lower edge of the front windshield, such as Area 1 in FIG. 2, it does not form visual interference and is convenient for the driver to simultaneously observe the vehicle status and road conditions, therefore, it can be displayed continuously after the display is turned on; correspondingly, for example, Area 1 in FIG. 3 does not form visual interference and is convenient for passengers in the co-driver seat to simultaneously observe the vehicle status and road conditions, thereby reminding the driver's attention, therefore, it can also be displayed continuously after the display is turned on. In addition, for Areas 1 in FIGS. 2 and 3, the information related to vehicle machine control can also be displayed, such as information related to diagnostic results of vehicle status, such as whether there is a fault of the engine, whether the oil needs to be replaced, or whether the water tank needs to be filled with water or antifreeze.
In conjunction with the above examples in FIGS. 2 and 3, it can be seen that the division of these areas can be different for each person inside the vehicle, that is, different partition schemes can be customized for each person inside the vehicle. In addition, for Area 4 in FIG. 2, it may partially overlap with Area 3 in FIG. 3. For example, after the driver starts the engine, the display of the display sub-area corresponding to the default first partition mode (such as the display sub-area shown in FIG. 2) can be activated when it is determined that no passenger is seated in the co-driver seat. When it is determined that a passenger is seated in the co-driver seat, the default second partition mode (such as the display sub-area shown by merging FIG. 2 and FIG. 3 as described above) will be activated for display. Of course, it is also possible to configure the activation of display sub-areas based on input selection of the central control screen, for example, the display can be performed using the partition scheme shown in FIG. 3. Here, the applicant of this application wishes to emphasize that such partition does not necessarily need to be implemented simultaneously, for example, the front windshield can mainly display content to the driver according to the partition scheme shown in FIG. 2, or to the passenger in the co-driver seat according to the partition scheme shown in FIG. 3.
The above introduces the division method of the display area. For display, in addition to displaying content, displaying direction is also important. The configuration of displaying direction is more based on the desired object to be displayed, the specific position of the display sub-area on the front windshield, and the properties of the content to be displayed (such as privacy and symmetry) . For example, when considering the need to display both inside and outside the vehicle, it is necessary to consider the symmetry of the display content to avoid the natural mirror flip of the same content on both inside and outside displays. Specifically, for Area 3 in FIG. 2, if it displays navigation information, it may belong to private information for occupants inside the vehicle, but if it is visible to personnel outside the vehicle, it is not expected, therefore, Area 3 in FIG. 2 can be arranged to only display content to the interior of the vehicle. For Area 2 in FIG. 2, if it displays warning information (such as a large warning arrow) that warns of potential collisions, it is important for the driver of the vehicle and the person or vehicle in front of it, in this case, for example, the display direction of Area 2 in FIG. 2 can be arranged to display content both the interior and the exterior of the vehicle, so that relevant personnel inside and outside the vehicle can receive the prompted warning information.
As a further example, Areas 1, 2, and 3 in FIG. 2 may not overlap with Areas 1, 2, and 3 in FIG. 3, as mentioned above, Areas 1, 2, 3, and 5 in FIG. 2 and Areas 1, 2, 3, and 5 in FIG. 3 can be used as a complete division scheme for the front windshield. If the display of Area 2 in FIG. 3 is, for example, a reminder to pedestrians on a zebra crossing, and the vehicle is in courtesy to pedestrians, such information is not important to the driver of the vehicle but to the pedestrians in front of it, correspondingly, the displaying direction of Area 2 in FIG. 3 can be arranged to only display content to the outside of the vehicle, so that relevant personnel outside the vehicle can receive the prompted information.
According to the disclosed concept, the display directions of a plurality of display sub-areas on the front windshield can be flexibly configured according to the specific needs of actual application scenarios. In general, the plurality of display sub-areas are configured for: at least one display sub-area of the plurality of display sub-areas is configured to simultaneously display content to both the interior and exterior of the vehicle; and/or at least one display sub-area of the plurality of display sub-areas is configured to display content to the interior of the vehicle; and/or at least one display sub-area of the plurality of display sub-areas is configured to display content to the exterior of the vehicle. In this way, the display sub-area can be flexibly selected for display according to the position of the display object of the information that needs to be displayed, thereby improving the pertinence and display effect of information display.
It can be seen that the five display sub-areas in FIG. 2 are independent of each other, similarly, the five display sub-areas in FIG. 3 are also independent of each other. Independence here does not necessarily mean that its formation must be completely independent, for example, a whole block of projection display functional layer or autonomous display functional layer which connect plurality of display sub-areas together can be arranged on the front windshield, at this time, the mutual independence among the plurality of display sub-areas is reflected by the mutually independent display content corresponding to each of the plurality of display sub-areas. Here, the projection display functional layer can be imaged together with by cooperating with the projector, while the autonomous display functional layer can be controlled by the display chip for imaging. In an embodiment according to the present disclosure, the projection display functional layer or the autonomous display functional layer covers the display area, and the projection display functional layer or the autonomous display functional layer is continuous and uninterrupted. In other words, the physical medium constructed for displaying is completely unitary, rather than being formed independently by plurality of units. Here, being composed as a whole does not mean that the projection display functional layer or the autonomous display functional layer must cover the entire front windshield, in fact, it only needs to cover the entire display area. Of course, those skilled in the art should understand that the projection display functional layer or autonomous display functional layer covering the entire front windshield is also a feasible implementation form. Optionally or alternatively, in an embodiment according to the present disclosure, the projection display functional layer or the autonomous display functional layer includes a plurality of units associated with a plurality of display sub-areas. For example, it can be either that each unit corresponds to a display sub-area one-on-one, or that some units correspond to some display sub-areas one-on-one, while others can correspond to other display sub-areas in a one-to-two or even one-to-many manner.
In an implementation form of a projection display functional layer included in an embodiment according to the present disclosure, the display control method 100 further includes the steps not shown in the figures, namely providing at least two projectors associated with each display sub-area of a plurality of display sub-areas. Referring to FIG. 2, in the partition scheme shown in FIG. 2, for example, five projectors can be provided, which can be arranged in the cover plate below the front windshield, on the A-pillar or in the position of the rearview mirror, or in other positions as long as the projection imaging of the corresponding area on the front windshield can be achieved. If five projectors are arranged, each one should take responsibility, that is, each projector is responsible for one display sub-area. If four projectors are arranged, one projector can be responsible for displaying the two adjacent display sub-areas, and the other three projectors can be responsible for displaying one display sub-area. Among them, independent display of two display sub-areas can be achieved using the projector whose hardware structure is designed and whose software is edited. Further preferably, the two adjacent display sub-areas can correspond to the two units of the projection display functional layer one-on-one, to further ensure the alignment of information display without interfering with non-display areas between the two display sub-areas. In this way, the corresponding projector can be responsible for information display of the corresponding area associated with it to achieve the relative exclusive use of the projector, thereby improving the stability and accuracy of the display solution according to the present disclosure. Of course, those skilled in the art can understand that the relatively specific purpose here is for the aforementioned partition modes, the same projector in different partition modes can be responsible for different display sub-areas. This can be achieved, for example, by adjusting the projection direction of the projector, in summary, the system can call and arrange corresponding projectors according to the needs of different partition modes.
In an embodiment according to the present disclosure, the display control method 100 can alternatively include the steps of providing a projector configured to project corresponding content on each of the plurality of display sub-areas. At this point, as mentioned previously, the display independence of each display sub-area of the plurality of display sub-areas is ensured by designing the hardware structure of the projector and editing its software. Further preferably, the plurality of display sub-areas can correspond to the plurality of units of the projection display functional layer one-on-one to further ensure the alignment of information display without interfering with non-display regions among the plurality of display sub-areas. In this way, the projector can be responsible for information display of at least two corresponding areas associated with it to achieve the multi-purpose of the projector, thereby improving the economy of the display solution according to the present disclosure.
Preferably, in an embodiment according to the present disclosure, displaying corresponding content in the plurality of display sub-areas includes displaying different contents in the plurality of display sub-areas.
The above technical solution can be implemented not only through software and other control methods, but also through corresponding hardware circuits, for example. In other words, the above presentation control method can be achieved by combining the software stored in a computer-readable storage medium with corresponding hardware components. The computer readable storage medium is loaded with computer readable program instructions for executing various embodiments of the present disclosure. The computer-readable storage medium can be a tangible device that can hold and store instructions used by an instruction executing device. The computer-readable storage media, for example, may be but not limited to an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the above. More specific examples of computer-readable storage media (non-exhaustive) include: portable computer disk, hard disk, Random-access memory (RAM) , read-only memory (ROM) , erasable programmable read-only memory (EPROM or flash memory) , Static random-access memory (SRAM) , portable compressed disk read-only memory (CD-ROM) , digital multi-function disk (DVD) , memory stick, floppy disk, mechanical coding equipment, for example, a Punched card or a convex structure in a groove on which instructions are stored, and any suitable combination of the above. The computer-readable storage medium used here is not interpreted as an instantaneous signal itself, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagated through waveguides or other transmission media (such as optical pulses transmitted through fiber optic cables) , or electrical signals transmitted through wires.
FIG. 4 shows a schematic diagram of a display control device 400 according to an embodiment of the present disclosure. From Fig. 4, it can be seen that the display control device 400 includes a processor (such as a central processing unit (CPU) ) 410 and a memory 420 coupled to the processor 410. The memory 420 is configured to store computer executable instructions, causing the processor 410 to execute the display control methods 100 in the above embodiments when the computer executable instructions are executed.

At this time, the computer executable instructions stored in memory 420 cause the processor 410 to execute the display control method according to any of the embodiments of Fig. 1 of the present disclosure when executed. In this way, the display control can be achieved in the form of a display control device. As above mentioned, embodiments of the present disclosure divide the front windshield into a display area used to provide additional information display to the driver or passenger and a non-display area used to ensure the driver's driving safety, thereby improving the efficiency of information interaction between the vehicle and the person and the user experience while ensuring driving safety.
In order to more graphically describe a display control device according to the present disclosure, in addition to the processor and memory described above, FIG. 5 illustrates the projector 530 and the corresponding projection display functional layer 540 in certain implementations. Here, Fig. 5 shows a schematic diagram of a display system 500 according to an embodiment of the present disclosure. From Fig. 5, it can be seen that the display system 500 includes a processor (such as a central processing unit (CPU) ) 510 and a memory 520 coupled to the processor 510. In addition, in the embodiment shown in FIG. 5, the display system 500 also includes a projector 530, the display system 500 can project the information needed to be displayed onto the display sub-area corresponding to the projection display functional layer 540 for display by means of the projector 530.
Here, it should be understood by those skilled in the art that the projector is capable of projecting and that the projection can be displayed on a front windshield including, for example, a projection display function layer that may be laminated into the front windshield or attached to the surface of the front windshield.
In an embodiment according to the present disclosure, the projection display functional layer or the autonomous display functional layer is at least arranged in a first sub-area in the center of the front windshield.

Although it is described above that the various example embodiments of the present disclosure can be implemented in hardware or a dedicated circuit, the above-mentioned data processing device for data processing can be implemented in the form of hardware or software, which can be achieved in the form of software, because: in the 1990s, a technological improvement can easily belong to the improvement of the hardware (for example, the improvement of the circuit structure of diodes, transistors, switches, etc. ) or the improvement of software (for example, the improvement of method flow) . However, with the continuous development of technology, the improvement of many method processes nowadays can almost be implemented by programming the improved method process into the hardware circuit, in other words, the corresponding hardware circuit structure can be obtained by programming different programs of the hardware circuit, the change of the hardware circuit structure is implemented, that is, the improvement of such a method flow can also be regarded as a direct improvement of the hardware circuit structure. Therefore, it cannot be considered that the improvement of a method flow cannot be implemented by hardware entity modules. For example, a programmable logic device (PLD) (such as a Field Programmable Gate Array (FPGA) ) is an integrated circuit whose logic function is determined by the user's programming of the device. It is programmed by the designer to "integrate" a digital system on a programmable logic device without requiring the chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, instead of manually making integrated circuit chips, this kind of programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing, but the original code must also be written in a specific programming language before compiling, which is called Hardware Description Language (HDL) , and HDL is not only one language, but there are many languages, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language) , Confluence, CUPL (Cornell University Programming Language) , HDCal, JHDL (Java Hardware Description Language) , Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language) , etc., currently the most commonly used is VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that the method flow needs to be logic programmed using the above-mentioned hardware description languages into an integrated circuit, which can easily obtain the hardware circuit that implements the logic method flow.
The computer readable program instructions or computer program products used to execute various aspects of the disclosure of the present disclosure can also be stored in the cloud. When needed, the user can access the computer-readable program instructions used to execute one aspect of the disclosure of the present disclosure through the mobile Internet, the fixed network or other networks, so as to implement the technical solutions disclosed in each aspect of the disclosure of the present disclosure.
The foregoing descriptions are only alternative embodiments of the disclosure of the present disclosure, and are not used to limit the embodiments of the present disclosure, for those skilled in the art, the embodiments of the present disclosure may have various modifications and changes. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the embodiment of the present disclosure should be included in the protection scope of the embodiment of the present disclosure.
