Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] The illustrations provided in the following embodiments only schematically illustrate the basic concept of this application. Therefore, only the components related to this application are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The actual shape, number, and ratio of each component during actual implementation can be arbitrarily changed, and the component layout shape may also be more complex.

[0024] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0025] Please refer to Figure 1 , Figure 1 which shows a schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied. As Figure 1 shown, the system architecture includes an image acquisition device 101, an eye tracking sensor 102, an ambient light sensor 103, and an adjustment controller 104. Among them, the adjustment controller 104 can be one of a microcomputer, an embedded computer, etc.; after the adjustment controller 104 acquires and analyzes the original perception data collected by the image acquisition device 101, the eye tracking sensor 102, and the ambient light sensor 103, it adjusts the heads-up display (HUD) heads-up display parameters to adapt to the optimal line of sight range of the current user, and realizes personalized configuration of seamless interaction without manual adjustment.

[0026] In some embodiments of the present application, the image acquisition device 101 is used to acquire the current face image of the current user to detect the target driving posture, and to obtain the heads-up display parameters matching the current user in the heads-up display based on the recognized current face information; the eye tracking sensor 102 is used to capture the line of sight trajectory to obtain the line of sight angle offset; the ambient light sensor 103 is used to sense the current illumination intensity of the external ambient light to adjust the display brightness and display contrast in the heads-up display parameters.

[0027] During driving, the current user's line of sight angle shifts due to road conditions, fatigue posture adjustment, seat adjustment, etc., and the HUD cannot dynamically adaptively adjust; moreover, the personalized configuration of the current user cannot be involved in the adjustment process of the HUD, and the interaction optimization is poor.

[0028] To solve the above technical problems, the present application provides a method, device, electronic device, and storage medium for adjusting a heads-up display. The implementation details of the technical solution of the embodiments of the present application are elaborated in detail below.

[0029] Please refer to Figure 2 , Figure 2 which shows a flowchart of a method for adjusting a heads-up display according to an embodiment of the present application. As Figure 2 shown, in an exemplary embodiment, the method for adjusting a heads-up display includes at least steps S210 to S230. The details are introduced as follows:

[0030] Step S210: Obtain the head-up display parameters that match the current user in the head-up display.

[0031] Among them, the head-up display parameters include the display area and the display angle.

[0032] Step S220: If it is detected that the seat is adjusted, adjust the first parameter configuration of the display area based on a preset first mapping relationship, the seat adjustment distance, and the seat adjustment direction.

[0033] Among them, the first parameter configuration includes at least one of the position offset configuration and the size configuration, and the first mapping relationship is used to represent the conversion relationship between the seat adjustment distance, the seat adjustment direction, and the first parameter configuration.

[0034] Step S230: If it is detected that the current duration of the target driving posture is greater than or equal to the preset duration, adjust the second parameter configuration of the display area and the display angle based on a preset second mapping relationship and the detected line-of-sight angle offset.

[0035] Among them, the second parameter configuration includes at least one of the first parameter configuration and the angle configuration corresponding to the display angle, and the preset second mapping relationship is used to represent the conversion relationship between the line-of-sight angle offset and the second parameter configuration.

[0036] In some embodiments of the present application, the current user is used to represent the driver currently located in the driver's seat, and the head-up display parameters are the personalized settings of the current user.

[0037] In some embodiments of the present application, the position offset configuration is used to represent the left-right translation adjustment and the up-down translation adjustment of the display area of the head-up display along the horizontal direction.

[0038] In some embodiments of the present application, the size configuration is used to represent the horizontal expansion adjustment and the horizontal contraction adjustment of the display area of the head-up display.

[0039] In some embodiments of the present application, the angle configuration is used to represent the left-right rotation adjustment of the display area of the head-up display with the vertical central axis as the axis, and the up-down rotation adjustment with the horizontal central axis as the axis.

[0040] In some embodiments of the present application, in step S220, after the seat is adjusted, adjust the first parameter configuration of the display area to ensure that the display information is always within the best line-of-sight range of the current user.

[0041] In some embodiments of the present application, in step S230, the preset duration is used to ensure that the display information is always within the best line-of-sight range of the current user, and to avoid discomfort caused by frequent adjustment.

[0042] In some embodiments of the present application, the execution order of step S220 and step S230 is dynamically triggered based on the actually detected conditions, and the present application does not limit the execution order.

[0043] In some embodiments of the present application, the present application realizes that the best line of sight range of the current user always matches the display information of the HUD through the linkage between the position signal of the seat and the adjustment controller corresponding to the HUD. This not only significantly improves the comfort during driving, but also further improves the driving safety by reducing the actual line of sight angle deviation and manual operations.

[0044] In some embodiments of the present application, obtaining the head-up display parameters matching the current user in the head-up display includes: identifying the current face image corresponding to the current user to obtain the current face information; if the current face information successfully matches the preset user face information, then determining the head-up display parameters corresponding to the current face information as the head-up display parameters matching the current user in the head-up display; if the current face information fails to match the preset user face information, then determining the preset display parameters in the head-up display as the head-up display parameters matching the current user.

[0045] In some embodiments of the present application, the image acquisition device includes an in-vehicle camera.

[0046] In some embodiments of the present application, after the current user enters the vehicle, the in-vehicle camera is automatically activated to collect the current face image for face recognition, and the head-up display parameters of the HUD corresponding to the current user are pre-loaded to ensure that the display information of the HUD accurately matches the best line of sight range of the current user. Moreover, if the vehicle is shared by multiple drivers, multiple sets of head-up display parameters of the HUD can be stored to achieve automatic switching, providing personalized configurations for each driver, reducing the manual adjustment steps before driving, and making the driving process more convenient and safe.

[0047] In some embodiments of the present application, if the face recognition determines that the current user is driver A, then quickly load the personalized configuration of driver A, including the display brightness of the HUD being 12000 nits (nit), the display angle being 3° upward inclination, and the display area being adjusted 1° downward from the direct front of the line of sight, so that the display information of the HUD is always within the best line of sight range of A.

[0048] In some embodiments of the present application, if the face recognition determines that the current user is driver B, then automatically switch to the personalized configuration of the driver. For example, the display brightness of the HUD is adjusted to 10000 nits, the display angle is 2° downward inclination, and the display area of the HUD is relatively low to adapt to the relatively low actual driving posture and line of sight deviation angle of driver B.

[0049] In some embodiments of the present application, if the face recognition result is a stranger, that is, the current face information fails to match the preset user face information, the preset display parameters will be loaded as the head-up display parameters corresponding to the current user. For example, the display brightness of the HUD is set to 8000 nits, the display angle remains horizontal, and the display area is fixed 2° below the center of the line of sight directly ahead, so as to maintain basic safety and usability, provide a basic and stable visual experience, avoid visual interference caused by the display information of the HUD being too bright or the display position being too off, and improve the driving experience.

[0050] In some embodiments of the present application, if a seat adjustment is detected, the first parameter configuration of the display area will be adjusted based on a preset first mapping relationship, the seat adjustment distance, and the seat adjustment direction, including: if the seat adjustment direction is an upward adjustment, the display area will be moved upward along the vertical direction by a fifth offset angle; if the seat adjustment direction is a downward adjustment, the display area will be moved downward along the vertical direction by a sixth offset angle; if the seat adjustment direction is a backward adjustment, the first change amount of the horizontal viewing distance will be determined based on the seat adjustment distance, and the display area will be horizontally expanded by a seventh offset angle based on the first change amount; if the seat adjustment direction is a forward adjustment, the second change amount of the horizontal viewing distance will be determined based on the seat adjustment distance, and the display area will be horizontally contracted by an eighth offset angle based on the second change amount; where the fifth offset angle and the sixth offset angle are used to represent the display area adjustment amount corresponding to the seat adjustment distance in the first mapping relationship, the seventh offset angle is used to represent the display area adjustment amount corresponding to the first change amount in the first mapping relationship, and the eighth offset angle is used to represent the display area adjustment amount corresponding to the second change amount in the first mapping relationship.

[0051] In some embodiments of the present application, when the seat adjustment direction is an upward adjustment or a downward adjustment, it is to adjust the seat height. When the seat adjustment direction is a forward adjustment or a backward adjustment, it is to adjust the front-back position of the seat.

[0052] In some embodiments of the present application, during driving, when the current user adjusts the front-back position or the height of the seat, the electronic control unit (ECU) of the seat will detect these changes in real time and send the position signal to the adjustment controller corresponding to the HUD through the gateway. According to the received position signal, the display area of the HUD is automatically adjusted to ensure that the display information of the HUD matches the best line of sight range of the current user, thereby improving the comfort of the driving experience and the safety of the driving process.

[0053] In some embodiments of the present application, for example, if the current user adjusts the seat height upward by 3 cm, the display area of the HUD will be automatically moved upward by 1° in the vertical direction to adapt to the new optimal line of sight range of the current user; similarly, if the seat height is adjusted downward by 3 cm, the display area of the HUD will be moved downward by 1° in the vertical direction to ensure that the current user can comfortably view the display information.

[0054] In some embodiments of the present application, if the current user moves the seat backward by 3 cm, the first change amount of the horizontal line of sight distance will be automatically calculated, and the display area will be horizontally expanded by 0.5° corresponding to the first change amount, so as to adapt to the visual needs of the current user after the backward adjustment.

[0055] In some embodiments of the present application, after the seat is adjusted, the adaptive adjustment mechanism effectively reduces the current user's attention to the HUD display adjustment, enabling them to focus on driving operations and improving safety.

[0056] In some embodiments of the present application, if it is detected that the current duration of the target driving posture is greater than or equal to the preset duration, the second parameter configuration of the display area and the display angle will be adjusted based on the preset second mapping relationship and the detected line of sight angle offset, including: if the current duration of the first driving posture is greater than or equal to the preset first duration threshold, the second parameter configuration of the display area and the display angle will be adjusted based on the preset second mapping relationship and the detected line of sight angle offset; if the current duration of the second driving posture is greater than or equal to the preset second duration threshold, the second parameter configuration of the display area and the display angle will be adjusted based on the preset second mapping relationship and the detected line of sight angle offset; wherein, the target driving posture includes the first driving posture after the posture change, and the second driving posture that has lasted for the preset second duration threshold, the preset duration includes the preset first duration threshold and the preset second duration threshold, and the preset second duration threshold is obtained based on the historical posture change habit information of the current user.

[0057] In some embodiments of the present application, the preset first duration threshold can be set to 5 minutes.

[0058] In some embodiments of the present application, the target driving posture can be characterized by the head posture.

[0059] In some embodiments of the present application, when the actual driving posture of the current user changes, and after the first driving posture after the posture change lasts for more than 5 minutes, the second parameter configuration will be slowly and slightly adjusted, for example, the display area of the HUD will be adjusted by 0.5° - 1° in the vertical or horizontal direction to ensure that the display information of the HUD is always within the optimal line of sight range of the current user and to avoid discomfort or visual interference caused by frequent adjustments.

[0060] In some embodiments of the present application, the present application further optimizes the adjustment of the head-up display parameters by learning the driving habits of the current user. The historical driving habits of the current user are collected, and the historical duration of maintaining the same historical driving posture is recorded. Thus, by analyzing the changes in the historical driving postures of the current user, the individualized posture change pattern is identified, and the historical posture change habit information is obtained. For example, in the historical posture change habit information of the current user, the sitting posture is usually adjusted after 12 minutes of daily driving, while during long-distance driving, it is extended to 25 minutes before the sitting posture is adjusted. Thus, the preset second duration threshold corresponding to the current user can be set to 12 minutes. When the current user maintains the same second driving posture for greater than or equal to 12 minutes, at least one of the display area and the display angle of the HUD will be adjusted in advance to ensure that the display information of the HUD is always within the best line of sight of the current user. By collecting the driving habits of the current user, the HUD avoids the driver's annoyance caused by frequent changes and completes the early fine-tuning of the HUD in a smooth and natural manner, ensuring that the information is clearly visible and improving the safety and comfort of driving.

[0061] In some embodiments of the present application, based on the preset second mapping relationship and the detected line-of-sight angle offset, the adjustment of the second parameter configuration of the display area and the display angle includes: if the direction of the line-of-sight angle offset includes the yaw angle direction, the display area is rotated left or right by a first offset angle with the vertical central axis as the axis; if the direction of the line-of-sight angle offset includes the pitch angle direction, the display area is rotated up or down by a second offset angle with the horizontal central axis as the axis; if the direction of the line-of-sight angle offset includes the horizontal direction, the display area is moved left or right along the horizontal direction by a third offset angle; if the direction of the line-of-sight angle offset includes the vertical direction, the display area is moved up or down along the vertical direction by a fourth offset angle; wherein, the first offset angle and the second offset angle are used to represent the display angle adjustment amount corresponding to the line-of-sight angle offset in the second mapping relationship, and the third offset angle and the fourth offset angle are used to represent the display area adjustment amount corresponding to the line-of-sight angle offset in the second mapping relationship.

[0062] In some embodiments of the present application, the yaw angle direction is used to represent the angle direction in which the line of sight rotates around the axis perpendicular to the horizontal plane of the current user; the pitch angle direction is used to represent the angle direction in which the line of sight rotates around the longitudinal axis of the current user.

[0063] In some embodiments of the present application, the vertical central axis is used to represent the axis perpendicular to the ground and passing through the center of the display area; the horizontal central axis is used to represent the axis parallel to the ground and passing through the center of the display area.

[0064] In some embodiments of the present application, the second mapping relationship includes the display area adjustment amount and the display angle adjustment amount for different gears to correspond to different angle offset ranges in the line-of-sight angle offset. For example, there are three gears of 0.5°, 0.7°, and 1°.

[0065] In the related art, when the HUD is dealing with a complex lighting environment, such as when entering or exiting a tunnel, a shadow area, or direct sunlight, the adjustment of the display brightness lags or cannot change in real time, resulting in the display information being too bright or too dark, affecting the clear reading and comfort of the current user.

[0066] In some embodiments of the present application, after obtaining the head-up display parameters matching the current user in the head-up display, it further includes: if it is detected that the current light intensity of the external ambient light changes from a first preset light intensity range to a second preset light intensity range, gradually adjust the display brightness in the head-up display parameters to a brightness threshold, and adjust the display contrast in the head-up display parameters based on the adjustment of the display brightness; wherein, the brightness threshold is obtained based on a preset third mapping relationship among the current light intensity, the second preset light intensity range, and the preset brightness range, or obtained based on a preset fourth mapping relationship between the second preset light intensity range and the historical brightness preference information of the current user.

[0067] In some embodiments of the present application, through the integrated ambient light sensor, the current light intensity of the external ambient light around the vehicle can be monitored in real time, and it can respond quickly when the external light changes, dynamically adjusting the display brightness and display contrast of the HUD.

[0068] In some embodiments of the present application, the preset light intensity range is set according to the lighting environment: in high-light conditions, such as at noon on a sunny day, the preset light intensity range can be set to 80000 lux (lux) to 100000 lux; in medium-light conditions, such as on a cloudy day or under a tree shade, the preset light intensity range is set to 20000 lux to 40000 lux; in low-light conditions, such as at night or in a tunnel, the preset light intensity range is set to 0 to 2000 lux.

[0069] In some embodiments of the present application, if the vehicle drives from a direct sunlight environment into a tunnel or a shaded area, and the current light intensity rapidly drops from 100,000 lux to 2,000 lux or even lower, the display brightness of the HUD can gradually decrease from 10,000 nits to 1,500 nits within 0.5 seconds, avoiding glare or light pollution caused by excessive brightness in the tunnel; when the vehicle exits the tunnel and enters a direct sunlight environment, and the current light intensity rises to 100,000 lux, the display brightness of the HUD rapidly increases to 8,000 - 10,000 nits, ensuring that the display information of the HUD is still clearly visible in a strong light environment. This dynamic adaptive adjustment mechanism can complete the adjustment of the display brightness within 0.3 - 0.5 seconds, effectively solving the problem of lag in the brightness adjustment of the HUD, and avoiding the driver being distracted or unable to see the display information clearly due to sudden changes in light, thereby improving driving safety and comfort.

[0070] In some embodiments of the present application, for example, on a rural road at night or in a weak light environment, if the current light intensity drops below 1,000 lux, the display brightness of the HUD is adjusted to 1,000 - 3,000 nits, reducing the glare and improving the comfort and safety of night driving. Whether entering a shaded area, a tunnel or a strong light area, the ambient light sensor can respond within milliseconds to achieve adaptive adjustment of the display brightness, reducing the manual operation burden of the driver and ensuring a safer and smoother driving process.

[0071] In some embodiments of the present application, the present application can identify historical brightness preference information based on the historical brightness control information of the current user. For example, under the condition that the second preset light intensity range is 80,000 lux (lux) to 100,000 lux, the corresponding brightness threshold is set to 10,000 nits; under the condition that the second preset light intensity range is 20,000 lux to 40,000 lux, the corresponding brightness threshold is set to 6,000 nits, and under the condition that the second preset light intensity range is 0 to 2,000 lux, the corresponding brightness threshold is set to 1,200 nits. By the above method, the display brightness of the HUD can be accurately adjusted according to the user's habit preferences, ensuring that the display brightness of the HUD always precisely meets the needs of the current user, avoiding discomfort caused by too high or too low display brightness, thereby improving the comfort and safety of the driver.

[0072] In some embodiments of the present application, the display contrast in the head-up display parameters is adjusted based on the adjustment of the display brightness, including: as the display brightness increases, the display contrast is increased to suppress the whitening of the display content under strong light; as the display brightness decreases, the display contrast is decreased to suppress the over-darkening of the display content under weak light.

[0073] In some embodiments of the present application, please refer to Figure 3 ,Figure 3 The figure shows a schematic flowchart of an adjustment method for a head-up display according to an embodiment of the present application. As Figure 3 shown, obtain the current face image collected by the image acquisition device: recognize the current face image to obtain the current face information; if the current face information matches the preset user face information successfully, load the head-up display parameters stored by the current user; if the current face information does not match the preset user face information, load the preset display parameters of the HUD; obtain the current light intensity of the ambient light sensor: if the light decreases, such as when driving into a tunnel and the current light intensity drops to 10 - 200 lux, then reduce the display brightness, such as adjusting it to 800 - 1500 nits; if the light decreases, such as when driving out of a tunnel and the current light intensity rises to 2000 - 10000 lux, then increase the display brightness, such as adjusting it to 8000 - 10000 nits; obtain the position signal of the seat: if the seat rises, move the display area upward to be level with the current user's line of sight; if the seat drops, move the display area downward to be level with the current user's line of sight, so that the current user can see the display information without having to look up.

[0074] In some embodiments of the present application, the present application uses multiple sensors such as an image acquisition device, an eye tracking sensor, and an ambient light sensor to collect the actual driving posture and line-of-sight angle deviation of the current user in real time, as well as the current light intensity of the external ambient light. The collected original perception data is preprocessed to ensure the accuracy and consistency of the data. This method of multi-modal perception fusion provides a basis for the display adaptive adjustment of the HUD, ensuring that the current user can clearly see the display information of the HUD under any conditions of actual driving posture, line-of-sight deviation angle, or external ambient light change, improving driving safety and comfort.

[0075] In some embodiments of the present application, the adjustment controller, as the core hub, comprehensively analyzes the state of the current user and the external ambient light, so as to accurately analyze the fixation point of the current user according to the change of the current user's line-of-sight angle deviation, actual driving posture, or the current light intensity change of the external environment light, enabling the adjustment controller to quickly command to adjust at least one of the head-up display parameters such as the display area, display angle, display brightness, and display contrast of the HUD, ensuring that the display information is always within the best line-of-sight range of the current user, making the HUD have a higher level of intelligence, and effectively improving the driving experience and safety.
