Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle screen display, in particular to a vehicle screen quality adjusting method and a vehicle. BACKGROUND

[0002] With the development of automobile intelligence, the vehicle screen has become the core interactive carrier of navigation, entertainment, vehicle monitoring and other functions, and its display effect directly affects driving safety and user experience. The balance between screen quality adjustment and new energy vehicle endurance is increasingly prominent.

[0003] The common vehicle screen energy saving scheme at present mostly displays and adjusts according to the remaining battery power of the vehicle, and automatically performs operations such as reducing backlight brightness and reducing display resolution when low power is detected to achieve the purpose of energy saving. However, this adjustment method usually does not fully consider the functional differences and actual presentation needs of different information content in the driving environment. For example, in the low power state, if the key information such as navigation path and safety warning and the regular entertainment content are treated with non-discriminatory brightness reduction and resolution reduction, it may lead to a decrease in the recognition of important driving information, and thus potentially affect the driver's judgment and operation.

[0004] Therefore, how to more flexibly adjust the display parameters of the vehicle display becomes a problem to be solved. SUMMARY

[0005] In view of the above problems, the present application provides a vehicle screen quality adjusting method and a vehicle which overcome the above problems or at least partially solve the above problems, and the technical solutions are as follows: The application discloses a method for adjusting the picture quality of a vehicle-mounted screen, which comprises the following steps: collecting a vehicle battery data set and a vehicle operation data set; determining a display requirement scene of a target operation scene corresponding to a current vehicle based on the vehicle operation data set; the display requirement scene is divided into a first driving scene and a second driving scene; determining a display priority corresponding to each display content displayed on at least one display screen on the current vehicle; obtaining a target display parameter corresponding to each display content by combining the vehicle battery data set, the display requirement scene and the display priority corresponding to each display content, so as to adjust the corresponding display content based on the target display parameter. The application can effectively solve the problem of fuzzy display of core information caused by the traditional one-size-fits-all strategy under low power consumption, ensure that the core information can be clearly presented under various working conditions, and guarantee the accuracy and reliability of the transmission of core information during use. At the same time, the adaptive adjustment is realized through comprehensive analysis of multi-dimensional data, and the method can be applied to various vehicle models through software optimization without additional hardware modification, so that the compatibility is strong, the cost is low, and the intelligence of the vehicle is improved.

[0006] Optionally, the combination of the vehicle battery data set, the display requirement scene and the display priority corresponding to each display content to obtain the target display parameter corresponding to each display content comprises the following steps: determining a battery state level based on the vehicle battery data set; matching a corresponding target picture quality adjustment strategy from a picture quality parameter library according to the battery state level, the display requirement scene and the display priority corresponding to each display content; the picture quality parameter library stores a plurality of groups of picture quality adjustment strategies corresponding to display conditions; wherein the display conditions comprise the battery state level, the display requirement scene and the display priority of the plurality of display contents; the picture quality adjustment strategy defines the display parameters corresponding to the plurality of display contents corresponding to each group of display conditions; and determining the target display parameter corresponding to each display content according to the target picture quality adjustment strategy.

[0007] The optional embodiment determines the battery state level through the vehicle battery data set, and then matches the corresponding target image quality adjustment strategy from the image quality parameter library according to the battery state level, the display requirement scene, and the display priority corresponding to the plurality of display contents, so as to combine the battery state level, the scene display requirement scene, and the display content priority to construct a three-dimensional decision structure, avoid problems such as core information blurring caused by low power one-size-fits-all and insufficient experience adaptation of high power, and realize accurate balance of energy saving, driving safety, and user experience. At the same time, the image quality parameter library is preset with a plurality of adjustment strategies corresponding to different display conditions, the specific display parameters of each display content are clearly defined, the adjustment operation is ensured to have rules to follow and stable and controllable effect, and the uncertainty caused by subjective adjustment is avoided.

[0008] Optionally, the battery state level is determined based on the vehicle battery data set, including: obtaining the remaining battery power in the vehicle battery data set, and determining the battery state level based on the remaining battery power; the battery state level is divided into: high power level, medium power level, and low power level.

[0009] The optional embodiment realizes standardized and clear definition of the battery endurance state by accurately extracting the remaining battery power and dividing it into three levels of battery state levels, which provides accurate and clear core decision basis for matching differentiated image quality adjustment strategies in combination with display content priority in the future.

[0010] Optionally, the display requirement scene of the target running scene corresponding to the current vehicle is determined based on the vehicle running data set, including: matching the corresponding display requirement scene according to the target running scene; wherein the first driving scene includes at least one of a navigation scene, a high-speed driving scene, and an alarm scene; and the second driving scene includes at least one of a video and audio entertainment scene and a parking waiting scene.

[0011] The optional embodiment realizes standardized and clear definition of the driving scene requirement by explicitly matching the target running scene into the first driving scene, i.e., the navigation, high-speed driving, and alarm scenes, and the second driving scene, i.e., the video and audio entertainment and parking waiting scenes, which are two different display requirement scenes, and provides accurate and clear core decision basis for matching differentiated image quality adjustment strategies in combination with display content priority in the future.

[0012] Optionally, determining the display priority of each of the multiple display contents displayed on the vehicle display screen includes: obtaining the multiple display contents currently displayed on the vehicle display screen; obtaining the display priority of each of the multiple display contents based on a preset mapping relationship; the preset mapping relationship includes the correspondence between different display contents and the display priority; wherein the display priority is divided into: core display information, secondary display information, and redundant display information; the core display information includes: navigation guidance, alarm prompts, and battery life data; the secondary display information includes: entertainment covers, weather widgets, and function icons; the redundant display information includes: dynamic effects, transition animations, and advertising pop-ups.

[0013] This optional implementation provides a core basis for differentiated image quality adjustment in different scenarios by setting display priority levels. It breaks away from the traditional mechanical adjustment logic that relies solely on power, making image quality adjustment more in line with information value and scenario needs, and greatly improving the intelligence and personalization level of vehicle image quality adjustment function.

[0014] Optionally, after adjusting the display parameters corresponding to the display content displayed on the vehicle display screen by combining the vehicle battery dataset, the target operating scenario, and the display priorities corresponding to the multiple display contents, the method further includes: restoring the display parameters of the multiple display contents when the vehicle is detected to be in a charging state.

[0015] This optional implementation restores the display parameters of the multiple displayed contents when the vehicle is detected to be charging, thereby making full use of the conditions under which the range constraint is lifted in the charging scenario, optimizing the screen display effect, and improving user satisfaction; at the same time, it improves the closed-loop logic of image quality adjustment, making the adjustment function more in line with actual use scenarios and improving the overall level of intelligent adaptation.

[0016] Optionally, the method further includes: when the vehicle is detected to be in a charging state, performing a restoration operation on the display parameters of the plurality of display contents, including: obtaining the charging power corresponding to the vehicle being in a charging state; when the charging power is less than a preset power threshold, gradually restoring the display parameters according to a preset gradient as the battery power of the vehicle increases; when the charging power is greater than or equal to the preset power threshold, restoring the display parameters to a preset image quality mode.

[0017] This optional implementation of the present application's embodiments designs a differentiated recovery strategy by distinguishing between slow charging and fast charging modes. This not only solves the energy waste caused by excessively rapid image quality recovery in slow charging scenarios, but also meets users' needs for a quick recovery of a high-quality experience in fast charging scenarios. Simultaneously, through mechanisms such as smooth adjustment and priority protection, the rationality and safety of the recovery process are ensured, further enhancing the user-friendliness and completeness of the technical solution. Optionally, determining the target display parameters corresponding to the multiple display contents according to the target image quality adjustment strategy includes: obtaining multiple display parameters carried in the target image quality adjustment strategy; the display parameters include the on / off state, brightness, contrast, saturation, and display area of ​​the corresponding display content; matching the multiple display parameters to the corresponding display content, and using them as the target display parameters of the display content.

[0018] This optional implementation method accurately extracts multi-dimensional display parameters, including the on / off status of display content, brightness, contrast, saturation, and display area, from the target image quality adjustment strategy. It can perform targeted parameter adjustments for display content with different priorities, ensuring that core information receives appropriate display resource allocation under various working conditions to guarantee clear visibility. It can also achieve precise energy saving by reasonably controlling secondary information and disabling redundant information, effectively balancing energy saving, safety, and user experience, and further improving the accuracy and intelligence of image quality adjustment.

[0019] Optionally, the method further includes: when an addition or deletion operation is detected in the display content of the vehicle display screen, re-determining the display priority of the updated display content based on the preset mapping relationship, and updating the corresponding target display parameters in combination with the current battery status level and display requirement scenario.

[0020] This optional implementation method is...

Detailed Implementation

[0026] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0027] With the development of automotive intelligence, in-vehicle screens have become the core interactive carrier for functions such as navigation, entertainment, and vehicle monitoring. Their display effect directly affects driving safety and user experience, and the issue of balancing screen quality adjustment with the range of new energy vehicles is becoming increasingly prominent.

[0028] Most common energy-saving solutions for in-vehicle screens adjust the display based on the vehicle's remaining battery power. This is achieved by automatically reducing backlight brightness and display resolution when the battery level is low. However, this approach often fails to adequately consider the functional differences and actual presentation requirements of various information content in a driving environment. For example, in a low-battery state, if critical information such as navigation routes and safety warnings are treated with the same brightness and resolution reduction as regular entertainment content, the visibility of important driving information may decrease, potentially impacting the driver's judgment and operation.

[0029] To overcome or at least partially solve the above problems, this application provides a method for adjusting the image quality of an in-vehicle screen, such as... Figure 1 As shown, Figure 1 This application provides a schematic flowchart of a method for adjusting the image quality of an in-vehicle screen, which specifically includes the following steps S101-S104: S101. Collect vehicle battery data set and vehicle operation data set.

[0030] Specifically, the vehicle battery dataset can be collected in real time through the vehicle energy management system (EMS), including parameters such as remaining battery charge (SOC), discharge power, charging status (whether it is charging), and charging power. The above data directly reflects the battery's range and energy supply status, providing a basis for subsequent judgment on whether the vehicle needs to collect energy-saving data.

[0031] Vehicle operation datasets can be collected through the linkage of onboard sensors and onboard systems. Specifically, they include navigation startup status (whether the navigation function is turned on), vehicle speed, alarm signal trigger status (such as collision warning, fault alarm, etc.), the type of currently running screen function (such as audio and video playback, system settings, parking assistance, etc.), and vehicle parking status. These data are used to accurately identify the current operating scenario of the vehicle and the intensity of the user's demand for screen display.

[0032] It should be noted that the above data is collected in a real-time continuous acquisition mode, with the acquisition frequency adapted to the rate of change of vehicle status, ensuring that the data can reflect the dynamic changes of battery status and operating scenarios in a timely manner; all data is transmitted and stored locally on the vehicle host, without relying on cloud interaction, reducing latency and ensuring data security, and no additional hardware acquisition equipment is required, which can be achieved simply by linking the existing vehicle system and sensors, reducing the cost of implementing the solution.

[0033] S102. Based on the vehicle operation dataset, determine the display requirement scenario of the target operation scenario corresponding to the current vehicle.

[0034] The display requirement scenarios are divided into: the first driving scenario and the second driving scenario.

[0035] In this embodiment, after obtaining the vehicle operation dataset, key feature parameters can be extracted from the dataset, such as navigation startup status, driving speed threshold judgment, alarm signal triggering status, screen function type, and parking status. Then, a pre-defined scene recognition and judgment rule can be used to further determine the current operating scenario of the vehicle. Specifically, by analyzing the characteristics of the vehicle operation scenario, the current demand for screen display effects, i.e., the display demand scenario, can be identified. This display demand scenario is used to distinguish the user's needs for screen display effects under different scenarios.

[0036] Specifically, the process of obtaining the display requirement scenario corresponding to the target running scenario can be as follows: Match the corresponding display requirement scenario based on the target operating scenario.

[0037] The display demand scenarios are divided into a first driving scenario and a second driving scenario; the first driving scenario includes at least one of a navigation scenario, a highway driving scenario, and an alarm scenario; the second driving scenario includes at least one of an audio-visual entertainment scenario and a parking standby scenario.

[0038] Specifically, if the target operating scenario is a high-demand driving scenario (navigation scenario, highway driving scenario, alarm scenario), then the corresponding display requirement scenario is the first driving scenario. In this scenario, the vehicle status information displayed on the screen, such as navigation, needs to be clearly distinguishable with minimal visual interference. If the target operating scenario is a low-demand driving scenario (audio-visual entertainment scenario, parking standby scenario), then the corresponding display requirement scenario is the first driving scenario. In this scenario, the display requirements of the screen do not need to be particularly clear, so energy-saving requirements can be prioritized.

[0039] It should be noted that the mapping relationship between the display requirement scenario and the target operating scenario is pre-stored in the vehicle host and is automatically generated based on the scenario recognition results, without the need for additional manual intervention.

[0040] This application embodiment's optional implementation clearly matches the target operating scenario into a first driving scenario, namely navigation, highway driving, and alarm scenarios, and a second driving scenario, namely audio-visual entertainment and parking standby scenarios. These two scenarios with different display requirements achieve a standardized and clear definition of driving scenario requirements, providing a precise and clear core decision-making basis for subsequent matching of differentiated image quality adjustment strategies based on the priority of display content.

[0041] For example, if any of the following conditions are detected: navigation is in the active state, driving speed is greater than a preset high speed threshold (e.g., 100km / h), or alarm signal is in the triggered state, the current target operating scenario is determined to be a high-demand driving scenario, i.e., the first driving scenario, such as the navigation scenario.

[0042] If it is detected that the screen is currently running audio-visual entertainment functions, the vehicle is in a parked state and there is no navigation start or alarm trigger, the current target operating scenario is determined to be a low-demand driving scenario, i.e., the second driving scenario, such as an audio-visual entertainment scenario.

[0043] Furthermore, in high-demand driving scenarios, users have extremely high requirements for the recognizability of core information on the screen (such as navigation and alarms), and it is necessary to prioritize ensuring the clarity of information; in low-demand driving scenarios, users are more concerned about visual experience or can accept moderate energy saving. By classifying scenarios, users can flexibly adjust the display parameters of the in-vehicle display screen as needed to balance the relationship between safety, experience and energy saving.

[0044] S103. Determine the display priority of each of the multiple display contents displayed on the vehicle display screen.

[0045] In this embodiment of the application, it is also necessary to further prioritize the content displayed on the current vehicle screen, clarify the importance of different content, and provide a basis for differentiated adjustment of display parameters.

[0046] Specifically, the system first acquires all content currently displayed on the in-vehicle display screen, including system function content, interactive content, and entertainment content. Then, based on a preset mapping relationship between display content and priority, it automatically classifies each display content. It should be noted that this mapping relationship is pre-set and stored in the in-vehicle host according to the importance and safety impact of information on the user during driving. It can be updated to adapt to new display content types via Over-the-Air (OTA) technology.

[0047] Furthermore, by clearly defining the priorities of different content, display resources can be allocated in a targeted manner during the adjustment process. For example, when the battery is low, priority can be given to ensuring the clarity of core display information, while turning off or weakening redundant display information, thus ensuring the display of core information is clear, accurate, and energy-saving.

[0048] S104. Combining the vehicle battery dataset, the display requirement scenario, and the display priorities corresponding to the multiple display contents, obtain the target display parameters corresponding to the multiple display contents, and adjust the corresponding display contents based on the target display parameters.

[0049] In this step, the collected vehicle battery dataset is first analyzed to determine the battery status level. Then, in conjunction with S102, display parameters for multiple display contents adapted to the current battery status and operating scenario are determined, thereby achieving intelligent and personalized image quality adjustment of the current in-vehicle screen.

[0050] Specifically, refer to Figure 2 As shown, the detailed steps of step S104 (adjusting the display parameters corresponding to the display content on the vehicle display screen based on the vehicle battery dataset, the target operating scenario, and the display priorities corresponding to the multiple display contents respectively) may include the following S1041-S1043: S1041. Based on the vehicle battery dataset, determine the battery state level.

[0051] In this embodiment of the application, this step requires determining the current energy-saving demand intensity, i.e., the battery state level, using parameters from the vehicle battery dataset. This provides accurate and standardized input conditions for subsequent matching of differentiated image quality strategies based on display content priorities, ensuring the scientific and targeted nature of the adjustment logic.

[0052] Specifically, the process of determining the battery state level based on the aforementioned vehicle battery dataset can be as follows: Obtain the remaining battery power from the vehicle battery dataset, and determine the battery state level based on the remaining battery power.

[0053] The battery status levels are divided into: high power level, medium power level, and low power level.

[0054] In this embodiment, the remaining battery charge (SOC) can be extracted from the collected vehicle battery dataset. The remaining battery charge is used as a judgment indicator, and combined with discharge power auxiliary calibration (to avoid misjudgment of the level due to instantaneous discharge), the battery status can be divided into three levels according to the preset charge level threshold: high charge level (SOC>50%, indicating that the battery range is sufficient and there is no mandatory energy saving requirement), medium charge level (20%≤SOC≤50%, indicating that the range needs to be moderately controlled to balance energy saving and user experience), and low charge level (SOC<20%, indicating that the range is tight and energy saving and core information display need to be prioritized).

[0055] It should be noted that the grading threshold can also be updated via OTA to adapt to the battery characteristics of different vehicle models and users' energy-saving preferences.

[0056] This application embodiment achieves a standardized and clear definition of battery life status by accurately extracting the remaining battery power and classifying it into three battery status levels: high, medium, and low. This provides a precise and clear core decision-making basis for subsequent matching of differentiated image quality adjustment strategies based on the priority of display content.

[0057] S1042. Based on the battery status level, the display requirement scenario, and the display priority corresponding to the multiple display contents, match the corresponding target image quality adjustment strategy from the image quality parameter library.

[0058] The image quality parameter library stores multiple sets of image quality adjustment strategies corresponding to display conditions. The display conditions include the battery status level, the display requirement scenario, and the display priority of multiple display contents. The image quality adjustment strategy specifies the display parameters corresponding to the multiple display contents for each set of display conditions.

[0059] Specifically, the image quality parameter library is a policy storage unit pre-installed on the vehicle's host. It is built based on a large amount of real vehicle test data, user habits, and driving safety standards. It includes all combinations of display conditions in three dimensions: battery status level, display demand scenarios, and display priority, as well as the optimal image quality adjustment strategy under the corresponding combination.

[0060] Each image quality adjustment strategy clearly defines the specific display parameters corresponding to different display priorities, such as the specific values ​​or adjustment ranges of brightness, contrast, and saturation, the size and position of the display area, and the on / off status of redundant information.

[0061] It should be noted that the image quality parameter library also supports remote updates via OTA technology. Based on new vehicle configurations, scenario requirements, or user feedback, new display condition combinations can be added and existing strategy parameters can be optimized to ensure the system's adaptability and scalability.

[0062] S1043. Based on the target image quality adjustment strategy, determine the target display parameters corresponding to the plurality of display contents respectively.

[0063] In this embodiment of the application, by using the target image quality adjustment strategy obtained above, the display parameters of the display content with different display priorities specified in the target image quality adjustment strategy can be obtained, and then the display parameters of the multiple display contents can be adjusted to the corresponding display parameters.

[0064] Furthermore, through the aforementioned steps S1041-S1043, this embodiment of the application can combine battery status level, scene display requirements, and display content priority to construct a three-dimensional decision structure, avoiding problems such as blurred core information due to a one-size-fits-all approach when the battery is low and insufficient experience adaptation when the battery is high, thus achieving a precise balance between energy saving, driving safety, and user experience. At the same time, by pre-setting multiple sets of adjustment strategies corresponding to different display conditions through the image quality parameter library, the specific display parameters of each display content are clearly defined, ensuring that the adjustment operation is systematic and the effect is stable and controllable, avoiding the uncertainty brought about by subjective adjustment.

[0065] This application collects vehicle battery and operational datasets, determines target operating scenarios and display content priorities, and adjusts display parameters accordingly. This differentiates the display parameters for multiple items, effectively solving the problem of blurred core information display caused by the traditional one-size-fits-all approach when battery is low. It ensures clear presentation of core information under various operating conditions, guaranteeing the accuracy and reliability of core information transmission during use. Furthermore, adaptive adjustment is achieved through comprehensive analysis of multi-dimensional data. No additional hardware modifications are required; this method can be applied to various vehicle models through software optimization alone, offering strong compatibility and low cost, thereby enhancing vehicle intelligence.

[0066] As an extension and refinement of the above embodiments, step S1043 (determining the target display parameters corresponding to the plurality of display contents according to the target image quality adjustment strategy) can be further refined into the following steps A and B: Step A: Obtain multiple display parameters carried in the target image quality adjustment strategy.

[0067] The display parameters include the on / off state of the corresponding display content, brightness, contrast, saturation, and display area.

[0068] Specifically, the target image quality adjustment strategy can be a structured data package, which is a dedicated configuration scheme based on the current battery status level, the target operating scenario, and the priority of each displayed content.

[0069] Furthermore, the on / off status of each display content (e.g., whether redundant information is allowed to be displayed), specific brightness values ​​(e.g., core information brightness 80%), specific contrast values ​​(e.g., core information contrast 75%), specific saturation values ​​(e.g., saturation 90% in audio-visual scenarios), and the range and coordinates of the display area (e.g., core information occupies 70% of the upper half of the screen) are obtained from the target image quality adjustment strategy. During the extraction process, the display content priority corresponding to each parameter is synchronously associated to avoid misalignment between parameters and content.

[0070] Step B: Match the plurality of display parameters to the corresponding display content, and use them as the target display parameters of the display content.

[0071] Specifically, for multiple display contents on the current display screen, multiple pre-configured display parameters can be matched one by one to the corresponding display contents according to the corresponding identifiers of each type of display content. After the matching is completed, the display parameters that establish a corresponding relationship with each type of display content are determined as the target display parameters used when that type of display content is visualized and output on the vehicle terminal.

[0072] Furthermore, when adjusting the target display parameters corresponding to each display content, the adjustment operation can be performed in the order of priority of core display information, secondary display information, and redundant display information. Priority is given to ensuring the display effect of core information related to driving safety, and then auxiliary information and non-essential information are processed in turn to ensure that the adjustment focus is highlighted.

[0073] Targeted adjustments can be made to display parameters for different types. Specifically, when adjusting the on / off status of display content, the rendering and output channels of redundant display information can be turned off in low-power scenarios to stop their display and save energy. Core display information is always turned on and is not affected by energy-saving strategies to ensure that key information is continuously presented. Secondary display information is turned on by default, and some non-essential content can be selectively turned off in extremely low-power scenarios.

[0074] When adjusting the brightness, contrast, and saturation of the displayed content, the extracted parameter values ​​can be converted into control signals that can be recognized by the hardware through the display screen color management module. The adjustment can be made gradually with an adjustment accuracy of 1%, and the adjustment time can be controlled within 1-2 seconds to avoid screen flickering or visual discomfort caused by sudden parameter changes (e.g., when adjusting from low brightness to high brightness, the adjustment should be gradually increased in increments of 5% per second). When adjusting the display area of ​​the content, screen partitioning technology can be used to divide the display area into dedicated partitions based on the display area parameters. The core display information is positioned in the core visible area directly in front of the driver's line of sight to avoid being blocked by other information; secondary information is shrunk to non-core areas such as screen corners and edges to reduce the display range and save resources.

[0075] Preferably, after adjustment, the actual display status data of the display screen (such as the current brightness detection value and the actual occupancy of the display area) is collected in real time and compared with the target parameters. If the deviation exceeds 5%, a secondary calibration is automatically started to ensure that the adjustment effect is completely consistent with the target strategy.

[0076] It should be noted that if the vehicle status changes during the adjustment process (such as the battery level increasing from low to medium, or the scene switching from navigation to parking), the current adjustment process will be immediately terminated, and the process will return to the strategy matching stage to re-acquire the target strategy before executing new parameter adjustments to ensure that the image quality is always accurately adapted to the current state.

[0077] This application embodiment accurately extracts multi-dimensional display parameters, including the on / off status of display content, brightness, contrast, saturation, and display area, from the target image quality adjustment strategy. It can perform targeted parameter adjustments on display content of different priorities, ensuring that core information receives appropriate display resource allocation under various working conditions to guarantee clear visibility. It can also achieve precise energy saving by reasonably controlling secondary information and disabling redundant information, effectively balancing energy saving, safety, and user experience, and further improving the accuracy and intelligence of image quality adjustment.

[0078] As an extension and refinement of the above embodiments, such as Figure 3 As shown, Figure 3 An illustrative flowchart of a method for adjusting the image quality of an in-vehicle screen provided in this application embodiment. Figure 3 The method includes the following steps S201-S206: S201. Collect vehicle battery data set and vehicle operation data set.

[0079] S202. Based on the vehicle operation dataset, determine the display requirement scenario of the target operation scenario corresponding to the current vehicle.

[0080] The display requirement scenarios are divided into: the first driving scenario and the second driving scenario.

[0081] S203. Obtain the multiple display contents currently displayed on the vehicle display screen.

[0082] In this embodiment of the application, all visible and background rendering display content data can be collected by traversing the current display output queue of the screen to form a complete set of display content, that is, to obtain multiple display contents currently displayed on the vehicle display screen.

[0083] Specifically, the collected display content includes a variety of information, including but not limited to system function information (such as navigation interface, alarm pop-up, battery life display bar), interactive operation information (such as function icons, settings menu), entertainment display information (such as video playback cover, dynamic background effects), and auxiliary information information (such as weather widget, time display), etc.

[0084] It should be noted that the data collection process can adopt a real-time dynamic monitoring mode. When the content displayed on the screen is added, turned off, or switched (such as when the user turns on navigation or turns off entertainment applications), the set of displayed content is immediately updated synchronously to ensure that the subsequent priority determination is consistent with the actual display status and to avoid inaccurate adjustment due to content lag.

[0085] S204. Based on the preset mapping relationship, obtain the display priority corresponding to each of the multiple display contents.

[0086] The preset mapping relationship includes the correspondence between different display contents and the display priority. The display priority is divided into: core display information, secondary display information, and redundant display information. The core display information includes: navigation guidance, alarm prompts, and battery life data. The secondary display information includes: entertainment covers, weather widgets, and function icons. The redundant display information includes: dynamic effects, transition animations, and advertising pop-ups.

[0087] Specifically, the preset mapping relationship records the unique correspondence between various display contents and display priorities. For example, navigation guidance corresponds to core display information, entertainment covers correspond to secondary display information, and dynamic effects correspond to redundant display information. Moreover, this mapping relationship supports remote updates via OTA technology and can flexibly adapt to newly added display content types (such as newly added vehicle status monitoring plugins) or adjust the hierarchical rules.

[0088] Furthermore, during the matching operation, each display content in the collected set of display content is compared with the display content type in the preset mapping relationship. Based on the comparison results, the corresponding display priority is automatically assigned without manual intervention, ensuring the efficiency and accuracy of the hierarchical classification.

[0089] Furthermore, embodiments of this application will divide the priority into three levels, specifically including: Core display information refers to key information that is directly related to driving safety and core user needs. The clarity and recognizability of this information are the primary goals. Even in low-battery energy-saving scenarios, the best display effect must be maintained. This includes navigation guidance (such as route planning, turn prompts, and distance display), alarm prompts (such as collision warnings, fault alarms, and speed limit reminders), and remaining battery data (such as remaining battery power, remaining range, and energy consumption status).

[0090] Secondary display information refers to supplementary information that assists users and does not affect core functions or driving safety. The display effect can be adjusted appropriately according to battery status and scenario requirements. When the battery is low, the display resource usage can be reduced. Specifically, it includes entertainment covers (such as music album covers, video thumbnails), weather widgets (such as real-time temperature and weather condition display), and function icons (such as Bluetooth connection icons and air conditioning control icons). Redundant display information refers to unnecessary decorative and transitional information. Whether or not it is displayed has no impact on driving safety or the use of core functions. Its main purpose is to optimize the visual experience. It can be turned off directly to reduce screen energy consumption when energy saving is required. Specifically, it includes dynamic effects (such as interface switching animations and background flow effects), transition animations (such as pop-up / disappearance animations), and advertising pop-ups (such as promotional information and service notification pop-ups).

[0091] The above steps S203 and S204 provide a core basis for differentiated image quality adjustment in different scenarios by setting the display priority hierarchy. This breaks away from the traditional mechanical adjustment logic that relies solely on power, making image quality adjustment more in line with information value and scenario needs, and greatly improving the intelligence and personalization level of vehicle image quality adjustment function.

[0092] S205. Combining the vehicle battery dataset, the display requirement scenario, and the display priorities corresponding to the multiple display contents, obtain the target display parameters corresponding to the multiple display contents, and adjust the corresponding display contents based on the target display parameters.

[0093] S206. When the vehicle is detected to be in a charging state, the display parameters of the plurality of display contents are restored.

[0094] In some embodiments, when the vehicle is in a charging state, i.e., when the range constraint is gradually lifted, the screen display parameters can be dynamically restored to avoid the continued poor picture quality experience caused by the previous energy-saving adjustment, while ensuring the rationality and safety of the restoration process, and further improving user satisfaction.

[0095] This step restores the display parameters of the multiple displayed contents when the vehicle is detected to be charging, thereby making full use of the conditions under which the range constraint is lifted in the charging scenario to optimize the screen display effect and improve user satisfaction; at the same time, it improves the closed-loop logic of image quality adjustment, making the adjustment function more in line with actual use scenarios and improving the overall level of intelligent adaptation.

[0096] Specifically, the detailed steps of step S206 (recovering the display parameters of the plurality of display contents when the vehicle is detected to be in a charging state) may include the following: Step 1: Obtain the charging power corresponding to the vehicle when it is in a charging state.

[0097] Specifically, dynamic power data during battery charging can be collected through the EMS system, with the collection frequency synchronized with the battery status data (e.g., once per second) to ensure that the power data can reflect changes in the charging mode in real time.

[0098] Preferably, the collected charging power data can be filtered to remove abnormal data caused by instantaneous fluctuations (such as power peaks at the initial stage of charging or power sudden changes caused by poor contact at the charging interface), and the average power of three consecutive collection cycles can be used as the judgment basis to avoid false triggering of strategies due to data errors. At the same time, battery charging status parameters (such as charging voltage and charging current) can be synchronously associated to help verify the accuracy of charging power, ensure that subsequent recovery operations are only performed under effective charging conditions, and eliminate interference from false charging signals.

[0099] Step 2: When the charging power is less than the preset power threshold, the display parameters are gradually restored according to the preset gradient as the battery power of the vehicle increases.

[0100] Specifically, when the charging power is determined to be less than a preset power threshold (for example, a preset power threshold of 30kW), it is determined to be a slow charging mode, which means that the current charging scenario is a slow charging scenario, characterized by a long charging cycle and a gradual increase in power. At this time, the display screen parameters can be restored through a preset gradient recovery rule.

[0101] In this embodiment of the application, the correspondence between the battery power increase range and the display parameter recovery ratio will be stored in the vehicle host in advance; for example, the correspondence can be set such that when the SOC increases by 10%, the brightness and saturation recover by 20%, the contrast recovers by 15%, the display area expands by 30%, and the redundant information is gradually enabled when the SOC is ≥50%.

[0102] Furthermore, SOC data is continuously acquired in real time during vehicle charging. When the SOC reaches a preset interval node, a corresponding parameter recovery operation is triggered.

[0103] Preferably, each parameter restoration adopts a gradual adjustment method, with the adjustment time controlled within a preset time. The parameter values ​​are gradually increased with an accuracy of 1%, avoiding visual discomfort caused by sudden changes in screen brightness and color. At the same time, the priority rules of the displayed content are maintained throughout the restoration process, with the parameter restoration range of core display information being higher than that of secondary and redundant information, ensuring that core information remains clear even if the vehicle starts moving during the restoration process.

[0104] Step 3: When the charging power is greater than or equal to the preset power threshold, the display parameters are restored to the preset image quality mode.

[0105] Specifically, when the charging power is determined to be greater than or equal to the preset power threshold, it is determined to be a fast charging mode. This means that the current charging scenario is a fast charging scenario, which has the characteristics of high charging efficiency and short user waiting time. At this time, a high-quality picture quality experience can be quickly restored.

[0106] It should be noted that the preset image quality modes can be divided into commonly used image quality modes and optimal image quality modes. The commonly used image quality modes are determined by the in-vehicle system by recording the image quality parameters (brightness, contrast, saturation, etc.) that the user manually adjusts during daily driving, and storing the most frequently used parameter combinations. The optimal image quality modes are based on the best combination of display parameters set according to the screen hardware performance (such as 100% brightness, 85% contrast, 90% saturation, displaying all content).

[0107] In this embodiment, when the vehicle is detected to be fast charging, a 10-minute countdown can be started immediately. During the countdown, the display parameters are gradually restored from the current energy-saving state to the user's commonly used image quality mode. The restoration process also adopts a gradual adjustment to avoid sudden parameter changes. If the battery SOC has reached 100% (fully charged) before the 10-minute countdown ends, the gradient restoration is directly terminated and the optimal image quality mode is switched. If the battery is not fully charged after the countdown ends, the user's commonly used image quality mode is maintained until it is fully charged and then switched to the optimal mode.

[0108] In some embodiments, if the user's commonly used image quality mode is not recorded (such as the first charge of a new car), the display parameters will be restored to the preset standard image quality mode by default to ensure that the function works normally.

[0109] This application's embodiments design differentiated recovery strategies by distinguishing between slow charging and fast charging modes. This not only solves the energy waste caused by excessively rapid image quality recovery in slow charging scenarios, but also meets users' needs for a quick recovery of a high-quality experience in fast charging scenarios. At the same time, through mechanisms such as smooth adjustment and priority protection, the rationality and safety of the recovery process are ensured, further improving the user-friendliness and completeness of the technical solution.

[0110] It should also be noted that in some embodiments, the displayed content may be updated due to reasons such as the addition or deletion of displayed content caused by vehicle-mounted sensor detection or manual operation. In this regard, the embodiments of this application further include the following steps: When the addition or deletion of content on the vehicle display screen is detected, the display priority of the updated content is re-determined based on the preset mapping relationship, and the corresponding target display parameters are updated in combination with the current battery status level and display requirement scenario.

[0111] Specifically, when the vehicle display system detects that the content displayed on the vehicle display screen has been added or deleted, it can retrieve the pre-stored mapping relationship between display content and display priority, and redetermine the display priority of each of the updated display contents based on the mapping relationship. At the same time, the system collects the current battery status level of the vehicle and the display demand scenario of each display content in real time, and dynamically updates the target display parameters corresponding to each updated display content according to the preset priority and parameter adjustment rules of the display content.

[0112] This application embodiment can dynamically adjust the display priority and target parameters for adding or deleting content on the vehicle display screen. This avoids obscuring newly added high-priority display information with redundant content, promptly removes invalid information, ensures the driver can quickly capture core interactive information, and reduces information acquisition latency. Furthermore, it can consider the current battery status and display requirements, reducing brightness and refresh rate of non-core content to reduce energy consumption when the battery is low, while maintaining high visibility of high-risk warning content to ensure driving safety. Simultaneously, parameter adaptive adjustment can be completed without manual intervention, reducing the driver's workload and improving the intelligence level and driving comfort of the vehicle display system. Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented using software plus necessary general-purpose hardware platforms.
