[0057] Figure 3 A schematic diagram of an electronic device according to an embodiment of the present application. DETAILED DESCRIPTION

[0058] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0059] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0060] Heads-Up Display (HUD) is a driving assistance technology whose display screen is the vehicle's front windshield. Vehicle information, navigation instructions, weather information, music playback and other content can be projected onto the front windshield through projection equipment. The driver can obtain vehicle, navigation, weather, music playback and other information through the front windshield while driving, without having to look down at the central control display screen, mobile phone, etc., thereby improving driving convenience and comfort.

[0061] However, existing head-up displays (HUDs) typically have fixed content, with parameters such as the number of items displayed and the display area remaining constant. In certain situations, this excessive display can draw the driver's attention and potentially distract them. Because the HUD's display screen is located directly in front of the driver, in situations such as driver fatigue or complex driving, the HUD can fail to assist the driver and, in fact, increase driving risks, compromising safety.

[0062] When a driver is fatigued, their attention is limited. The driver's attention span increases as they try to comprehend the various information displayed through the windshield. This not only exacerbates driver fatigue, but also further distracts them, increasing driving risks. Driving in complex driving environments, such as mountainous areas, densely populated roads, and inclement weather, often requires the driver to maintain a high level of focus to prevent and respond promptly to emergencies. However, in such complex driving environments, the sheer volume of information displayed by a heads-up display (HUD) can distract the driver, hindering their ability to react promptly to emergencies and increasing driving risks. Furthermore, complex driving environments present a greater amount of distracting information. Since HUDs use the windshield as their display screen, their clarity is limited. This creates a situation where drivers must focus their attention and energy to discern and filter the key information presented by the HUD. The greater the amount of information displayed, the slower and less efficient the driver's ability to grasp the key information, significantly impacting driving safety. At the same time, to ensure the driver clearly understands the content of the heads-up display, the head-up display area typically occupies a large area on the front windshield. When the driver is fatigued or driving in complex driving conditions, the larger display area is more likely to distract the driver and cause serious visual interference, thereby affecting the driver's driving judgment and, in turn, driving safety. In addition, in some cases, when driver fatigue is detected, the head-up display can display a hazard warning. However, the sudden display of a hazard warning on the front windshield can quickly attract the driver's attention, exacerbating the driver's distraction in an instant and endangering driving safety.

[0063] Obviously, since the content of existing head-up displays is usually fixed, in special circumstances such as driver fatigue or complex environments, the numerous displayed contents will attract the driver's attention, making it difficult for the driver to concentrate on driving, thus affecting driving safety.

[0064] In view of this, the present application provides an information display method that can effectively improve driving safety, such as Figure 1 As shown, the method includes:

[0065] S101, in response to the head-up display function of the current vehicle being enabled, collecting the driver's current action information, the current vehicle's driving parameter information, and the current vehicle's driving environment information;

[0066] Specifically, the current action behavior of the driver can be captured by a camera device, and then the current action information can be obtained based on the analysis of the current action behavior. The camera device can be installed in front of the main driver to shoot real-time video of the driver, and then the image frame containing the driver is intercepted from the video stream for analysis to obtain the current action information; the camera device can also be used to take real-time photos of the people in the car, and the driver's current action information can be obtained by analyzing the continuously taken real-time photos. There are no specific restrictions. Driving parameter information can be directly obtained from the relevant controllers of the current vehicle, the vehicle central control platform, etc., and driving environment information can be obtained through sensors, cameras, etc. installed around the vehicle body. There are no specific restrictions.

[0067] S102 : reducing the amount of display content displayed by the head-up display function or reducing the area of ​​a display region corresponding to the display content according to the current action information, the driving parameter information, and the driving environment information.

[0068] Specifically, the head-up display function can display content including driving-related information, vehicle control system status information, entertainment information, and other information. Driving-related information refers to information directly related to driving operations, such as vehicle speed information, navigation information, gear information, distance information to the vehicle in front, lane line information, etc. Vehicle control system status information refers to information that indicates whether the vehicle control-related system is turned on or has a fault, such as ADAS status information, ABS status information, etc. Entertainment information refers to some entertainment-related information used to improve driving comfort, such as music playback information. Other information includes other information that can be displayed through the head-up display function, such as weather information.

[0069] When the driver is in an abnormal state such as distraction or fatigue, there will be some abnormalities in his or her behavior. Therefore, by collecting the driver's current behavior and analyzing the current behavior to obtain current behavior information, the driver's abnormal state such as distraction and fatigue can be effectively captured. When the vehicle is in certain specific environments or under specific driving parameters, the driving risk factor will increase significantly, such as high-speed driving, driving on narrow roads in mountainous areas, etc. Therefore, by collecting and analyzing driving parameter information and driving environment information, situations with higher driving safety risks can be effectively captured. After the head-up display function is turned on, the driver's state and driving conditions are determined by collecting current action information, driving parameter information and driving environment information, thereby determining whether it is necessary to improve the driver's concentration, thereby determining to reduce the amount of display content displayed by the head-up display function or reduce the area of ​​the display area corresponding to the display content.

[0070] In this application, based on steps S101 to S102, when the head-up display function of the current vehicle is enabled, the driver's current action information, the current vehicle's driving parameter information and the driving environment information of the current vehicle are collected in real time to evaluate the driver and the driving situation; when the driver's current attention is not focused enough, or the current driving road conditions are relatively complicated and the driver needs to concentrate highly, the amount of display content displayed by the head-up display function is reduced, or the area of ​​the display area corresponding to the display content is reduced; on the one hand, the driver's state and driving situation are accurately perceived, and the head-up display function is adaptively adjusted based on the driver's state and driving situation to ensure that the driver is focused. The high correlation between driver status, driving conditions and information display improves the driver's information acquisition efficiency, reduces driving risks, and enhances driving experience and safety. On the other hand, when the amount of displayed content is reduced or the area of ​​the display area is reduced, it can effectively reduce the visual information interference to the driver, reduce the factors that distract the driver's sight and attention, significantly reduce the driver's attention distraction caused by information overload, and effectively improve the driver's attention. Especially in complex or dangerous driving scenarios, the reduction in the amount of displayed content can help the driver quickly extract core information, thereby improving driving reaction speed and accuracy, improving driving safety, reducing the incidence of traffic accidents, and improving overall road safety.

[0071] When the driver's attention is focused, their movements are fewer and smaller in magnitude. Conversely, more movements and larger movements distract the driver's attention. Therefore, the driver's current state can be assessed by collecting information about their current movements to determine whether to reduce the amount of content displayed by the head-up display. In some embodiments, reducing the amount of content displayed by the head-up display based on the current movement information, the driving parameter information, and the driving environment information includes:

[0072] S201, evaluating the driver's current fatigue level based on the current action information;

[0073] Specifically, when a driver is fatigued or distracted, their behavior may change, such as looking down for extended periods, nodding frequently, looking away from the driving direction, or making excessive body movements. Therefore, by analyzing the driver's current behavior, we can accurately determine their current fatigue level. A higher fatigue level indicates a higher degree of distraction and fatigue.

[0074] S202, evaluating the current driving risk level of the vehicle based on the driving parameter information and the driving environment information;

[0075] Specifically, when a vehicle is traveling at high speeds or in complex environments or road sections, such as high speeds, on curves, in areas with high traffic density, or in poor weather, the driving risk factor is generally higher, and the probability of traffic accidents is higher. Therefore, using driving parameter information and driving environment information, the current vehicle's driving risk level can be accurately assessed. A higher driving risk level indicates a higher risk factor for the behavior and a higher probability of a traffic accident.

[0076] S203, reducing the amount of display content displayed by the head-up display function according to the current fatigue level and the driving hazard level;

[0077] The current fatigue level is negatively correlated with the number of displayed contents, and the driving hazard level is negatively correlated with the number of displayed contents.

[0078] Specifically, higher fatigue levels and driving risk levels indicate a higher driver focus to avoid accidents. Therefore, the head-up display content is reduced to retain core information, allowing the driver to quickly access it.

[0079] For example, during current vehicle driving, the head-up display function displays four types of content, specifically including vehicle speed information, navigation information, music information, and weather information. If the driver's current fatigue level is gradually increasing as assessed by real-time collection of current action information, or if the vehicle's driving risk level is gradually increasing as assessed by real-time collection of driving parameter information and driving environment information, the number of displayed contents in the head-up display can be gradually reduced as the current fatigue level or behavioral risk level increases, for example, from four to three, two, or one, or even until the head-up display function is turned off. If the current fatigue level or driving risk level reaches the highest level and persists for a period of time, the head-up display function can be directly turned off to ensure driving safety. The head-up display function will then be automatically turned on again when the driver's condition is detected to be normal and driving is safe.

[0080] Based on steps S201 to S203, the driver's current fatigue level is evaluated by real-time collection of the driver's current action information, and the driver's distraction and fatigue conditions are promptly obtained; the current vehicle's driving parameter information and driving environment information are collected in real time to evaluate the current vehicle's driving hazard level, and the driving safety status is promptly obtained; then the current fatigue level and driving hazard level are used to reduce the amount of display content displayed by the head-up display function. When the amount of content displayed on the glass in front of the driver's line of sight is reduced, the content that attracts the driver's attention will be reduced, thereby reducing interference to the driver. The energy required for the driver to obtain less information is significantly less than the attention and energy required to obtain multiple information, thereby prompting the driver to focus his limited energy on driving operations and improving driving safety.

[0081] Reducing the amount of content displayed by the head-up display can help the driver focus their limited attention on driving. Furthermore, reducing the area of ​​the display region corresponding to the displayed content can also help the driver focus better. In some embodiments, reducing the area of ​​the display region corresponding to the displayed content based on the current action information, the driving parameter information, and the driving environment information includes:

[0082] S201, evaluating the driver's current fatigue level based on the current action information;

[0083] Specifically, the current fatigue level can be set to multiple levels, such as 2, 3, 4, 5, and 6 levels. Multiple levels can be expressed by words, such as high, relatively high, medium, relatively low, and low, or by numerical values, such as level one, two, three, and four fatigue, etc., without specific restrictions; when numerical values ​​are used to set the levels, the smaller the numerical value corresponding to the level, the higher the level, and the higher the degree of fatigue and distraction; for example, when the current fatigue level is set to 3 levels, they are level one fatigue, level two fatigue, and level three fatigue, respectively. The levels of level one fatigue, level two fatigue, and level three fatigue gradually decrease, and the degree of distraction and fatigue also gradually decrease.

[0084] S202, evaluating the current driving risk level of the vehicle based on the driving parameter information and the driving environment information;

[0085] Specifically, the driving hazard level can be set to multiple levels, such as 2, 3, 4, 5, and 6 levels. Multiple levels can be expressed by words, such as high, relatively high, medium, relatively low, and low, or by numerical values, such as level one, two, three, and four, etc., without specific restrictions; when a numerical value is used to set the driving hazard level, the smaller the numerical value corresponding to the level, the higher the level and the higher the degree of driving hazard; for example, when the driving hazard level is set to 4 levels, they are level one, level two, level three, and level four, respectively. The level gradually decreases, and the corresponding driving hazard coefficient gradually decreases, and the probability of a traffic accident also becomes smaller.

[0086] S204, reducing the area of ​​the display region corresponding to the display content according to the current fatigue level and the driving hazard level;

[0087] The current fatigue level is negatively correlated with the area of ​​the display region, and the driving hazard level is negatively correlated with the area of ​​the display region.

[0088] Specifically, as the current fatigue level or driving hazard level increases, the area of ​​the display area corresponding to the displayed content becomes smaller. The area of ​​the display area can be reduced proportionally, that is, as the current fatigue level or driving hazard level increases, the area of ​​the display area gradually decreases by the same proportion each time, for example, by 10%, 15%, 20%, 25%, etc. each time. The area of ​​the display area can also be reduced non-proportionally. Since the area of ​​the display area is initially large, a larger reduction ratio can be set initially. As the area of ​​the display area decreases, the reduction ratio can be gradually reduced to ensure normal display of the displayed content, for example, the first, second, and third reduction ratios are 50%, 30%, 20%, etc. respectively. The area of ​​the display area can also be set to increase with each increase in the current fatigue level or driving hazard level, for example, the first, second, and third reduction ratios are 20%, 30%, 50%, etc. respectively, to ensure that the driver can focus more on driving operations. There are no specific restrictions.

[0089] In a head-up display (HUD), the vehicle's front windshield serves as the display screen, meaning the displayed content is displayed directly on the front windshield. The larger the display area corresponding to the displayed content, the larger the position and area it occupies on the front windshield. While larger display content tends to attract more of the driver's attention, larger display content can also block the driver's line of sight and cause more visual interference. This not only distracts the driver but, in special circumstances such as complex external environments, inclement weather, or driver fatigue, significantly increases the likelihood of driver misjudgment, impacting driving safety. Therefore, in this application, the area of ​​the display area is set to be smaller when the current fatigue level or driving hazard level is higher. This reduces visual interference with the driver and reduces distracting information, allowing the driver to focus on driving operations, thereby improving driving safety.

[0090] Based on the current fatigue level and driving hazard level, the area of ​​the display region corresponding to the displayed content can be reduced, as can the number of displayed contents displayed by the head-up display. When there are a large number of displayed contents, multiple displays coexist, causing visual interference between the displayed contents. The efficiency of extracting valid information from a smaller number of displayed contents is significantly higher than that from a larger number of displayed contents. When the area of ​​the display region corresponding to the displayed content is reduced, since the number of displayed contents is also smaller, it does not affect the driver's efficiency in extracting valid information. The smaller display region also causes less visual interference to the driver. Therefore, while effectively ensuring information extraction efficiency, it can further reduce visual interference, better encourage the driver to focus on driving operations, and thus improve driving safety.

[0091] When the head-up display function is enabled, to ensure that core important information can continue to be displayed, a priority can be set for the display content. When reducing the amount of display content displayed by the head-up display function, the display content to be stopped is determined based on the priority. In some embodiments, the display content includes multiple sub-display contents; reducing the amount of display content displayed by the head-up display function based on the current fatigue level and the driving hazard level includes:

[0092] Determining, according to the current fatigue level and the driving hazard level, the priority of the sub-display content currently required to be displayed as the target priority;

[0093] Stop displaying the sub-display content corresponding to a priority different from the target priority in the display content.

[0094] Specifically, the number of priorities may include multiple, such as 2, 3, 4, 5, 6, 7, 8, 9, etc., and more priorities may be set according to actual conditions, without specific restrictions; multiple levels may be represented by text, such as high, relatively high, medium, relatively low, low, etc., or by numerical values, such as first, second, third, fourth, etc., without specific restrictions; when numerical values ​​are used to set the levels, the smaller the numerical value corresponding to the level, the higher the priority. A corresponding priority is set for each sub-display content, and the priority setting of the sub-display content can be determined based on the relevance of the sub-display content to the driving operation. The higher the relevance to the driving operation, the higher the priority, and the lower the relevance to the driving operation, the lower the priority.

[0095] For example, three priorities are preset, namely the first level, the second level, and the third level. The priority of each sub-display content may be as shown in the following table:

[0096] Table 1 Sub-display content priority query table

[0097] Sub-display content Priority Driving related information First level Vehicle control system status information Second level Entertainment information, other information Third level

[0098] Driving-related information, vehicle control system status information, entertainment information, and other information usually include multiple specific pieces of information. Therefore, more priorities can be set to refine the priorities and sub-display content. For example, six priorities are preset: first level, second level, third level, fourth level, fifth level, and sixth level. The priority of each sub-display content can be shown in the following table:

[0102] For each fatigue level and danger level, the priority of the sub-display content to be displayed is pre-set. As the current fatigue level or driving danger level increases, the sub-display content with lower priority can be stopped from being displayed, and the sub-display content with higher priority can be displayed. For example, there are three fatigue levels preset: level 1 fatigue, level 2 fatigue, and level 3 fatigue. Taking the three priority levels as an example, the priority of the sub-display content corresponding to each fatigue level is shown in the following table:

[0103] Table 3 Correspondence between current fatigue level and priority of sub-display contents to be displayed

[0104] Current fatigue level The priority of the sub-display content that needs to be displayed Level 1 fatigue First level Secondary fatigue First level, second level Level 3 fatigue First level, second level, third level

[0105] There are four preset driving hazard levels: level one, level two, level three, and level four. Taking the four preset priorities as an example, the priority of the sub-display content corresponding to each hazard level is shown in the following table:

[0106] Table 4 Correspondence between driving hazard levels and priorities of sub-display contents to be displayed

[0107] Driving hazard level The priority of the sub-display content that needs to be displayed Level 1 danger First level Level 2 danger First level, second level Level 3 danger First level, second level, third level Level 4 danger First level, second level, third level, fourth level

[0108] Thus, when the current fatigue level and driving hazard level are evaluated, the priority of the sub-display content to be displayed can be determined based on the preset correspondence between each fatigue level and the priority of the sub-display content to be displayed, thereby obtaining a target priority. For example, when the current fatigue level is level three, the target priority can be determined to include the first, second, and third levels, and the sub-display content corresponding to the first, second, and third levels can be displayed, while the remaining content is not displayed. When the driving hazard level is level two, the target priority can be determined to include the first and second levels, and the sub-display content corresponding to the first and second levels can be displayed, while the remaining content is not displayed. When the target priorities determined based on the current fatigue level and driving hazard level are different, the sub-display content corresponding to the same priority in the two target priorities can be displayed, while the remaining display content is not displayed. For example, if the target priority determined based on the current fatigue level includes the first and second levels, and the target priority determined based on the driving hazard level includes the first, second, and third levels, then only the sub-display content corresponding to the first and second levels can be displayed, while the sub-display content corresponding to the third and remaining levels can be not displayed. In this application, after obtaining the current fatigue level and driving hazard level, the sub-display content that needs to be displayed can be determined based on them, so that the driver status, driving status and the importance of the sub-display content can be associated, and the sub-display content that does not match the driver status and driving status (that is, the sub-display content corresponding to a priority different from the target priority) can be stopped from being displayed first, effectively reducing factors that distract the driver's attention and improving driving safety.

[0109] Furthermore, the display parameters of the content to be displayed can be determined based on the current fatigue level and driving hazard level. These display parameters include icon size, font size, display color, dynamic display, and eye tracking. When the driver is distracted or fatigued, or driving is more dangerous, in addition to reducing the amount of content displayed by the head-up display or shrinking the corresponding display area, the display parameters of the remaining content to be displayed can be further modified. For example, the icon or font size of high-priority information (such as vehicle speed and navigation information) can be increased by 10%, 20%, or 30%. Lane information and preceding vehicle distance information can also be dynamically displayed, such as by setting a dynamic light strip for lane information to flow progressively along the driving direction or by flashing preceding vehicle distance information. For example, the display content can be configured to follow the driver's eye movements, so that the display area moves across the windshield, allowing the driver to capture the displayed information at any time. By modifying the display parameters of the required content, the required content or part of the required content can be highlighted, better reminding the driver of the current driving situation, thereby helping the driver to better focus and improve driving safety. When the driving risk level or current fatigue level is high, a reminder voice can be played through the voice playback device in the current vehicle, or connected to the current vehicle's driver's seat. When the corresponding driving risk level or current fatigue level is assessed, the driver's seat vibration function is activated. The higher the driving risk level or current fatigue level, the stronger the seat vibration, thereby reminding the driver to focus on driving and improving driving safety.

[0110] When a driver is tired or distracted, the angle and duration of his / her line of sight deviation will show obvious abnormalities. Therefore, the current fatigue level can be assessed by collecting the deviation of the driver's line of sight. In addition, when the driver performs certain actions that distract his / her attention, such as eating, making phone calls, turning his / her head to talk, looking around, etc., the driver's body movements can also be monitored to improve the accuracy of the current fatigue level assessment. In some embodiments, the current action information includes the horizontal deviation angle of the line of sight, the vertical deviation time of the line of sight, and the current body movement;

[0111] The evaluating the current fatigue level of the driver based on the current action information includes:

[0112] S301, determining a corresponding first index score according to the horizontal line of sight offset angle;

[0113] Specifically, the driver's line of sight when looking straight ahead is the origin, and the lateral offset angle of the driver's line of sight refers to the offset angle of the driver's line of sight from the origin in the horizontal direction. The lateral offset angle of the driver's line of sight is collected by setting a camera device in front of the driver's seat. Optionally, the horizontal offset angle of the driver's line of sight can be collected by collecting the horizontal offset angle of the driver's head, or by collecting the horizontal offset angle of the driver's pupil. There is no specific limitation. A correspondence between the preset horizontal offset angle of the line of sight and the first indicator score is preset. After monitoring the specific value of the horizontal offset angle of the line of sight, the corresponding score can be determined according to the preset correspondence.

[0114] For example, the corresponding relationship between the horizontal deviation angle of the sight line and the first indicator score is shown in the following table:

[0115] Table 5 Index score query table for lateral deviation angle of sight line

[0116] Horizontal deviation angle of sight First indicator score (0°,15°] 0.1 (15°,30°] 0.3 (30°,45°] 0.6 >45° 1

[0117] When it is detected that the horizontal deviation angle of the driver's line of sight is 10°, the first index score can be determined to be 0.1. When it is detected that the horizontal deviation angle of the driver's line of sight is 20°, the first index score can be determined to be 0.3.

[0118] S302, determining a corresponding second indicator score according to the longitudinal deviation time of the line of sight;

[0119] Specifically, the longitudinal offset time of the driver's line of sight refers to the length of time the driver's line of sight deviates from the origin in the longitudinal direction. The longitudinal offset time of the driver's line of sight is captured by setting a camera device in front of the driver's seat. Optionally, the longitudinal offset time of the driver's line of sight can be captured by capturing the longitudinal offset time of the driver's head, or by capturing the longitudinal offset time of the driver's pupil, without any specific limitation. A correspondence between the longitudinal offset time of the line of sight and the second indicator score is preset. After monitoring the specific duration of the longitudinal offset time of the line of sight, the corresponding score can be determined based on the preset correspondence.

[0120] For example, the corresponding relationship between the vertical deviation time of the line of sight and the second indicator score is shown in the following table:

[0121] Table 6 Index score query table for longitudinal deviation time of sight line

[0122]

[0123]

[0124] In the above table, t represents the longitudinal deviation time of the line of sight (unit: s). The longer the longitudinal deviation time of the line of sight, the higher the degree of distraction and fatigue, and the higher the impact on driving safety. Therefore, the second index score is set to increase exponentially to more accurately assess the driver's current fatigue level. When the longitudinal deviation time of the driver's line of sight is monitored to be 0.4s, the second index score can be determined as 0.1 according to the above table; when the longitudinal deviation time of the driver's line of sight is monitored to be 0.8s, the second index score can be determined as 0.2 (0.25×0.8=0.2) according to the above table; when the longitudinal deviation time of the driver's line of sight is monitored to be 3s, the second index score can be determined as 0.4e according to the above table. 0.18×3 (approximately 0.686).

[0125] S303, determining a corresponding third indicator score according to the current body movement;

[0126] Specifically, the driver's current body movements can be identified through a body recognition model. A camera device is used to capture the driver's action video or action image in real time, and then the captured video stream or image is input into the body recognition model for action recognition to obtain the driver's current body movement. The body recognition model can be constructed based on a long short-term memory network (LSTM), a bidirectional long short-term memory network (Bi-LSTM), a view adaptive neural network (VA) or a YOLO algorithm, or it can be constructed by integrating multiple algorithms, without specific restrictions. A plurality of corresponding relationships between current body movements and third indicator scores are preset. After the current body movement is identified, the corresponding third indicator score can be determined based on the corresponding relationship.

[0127] For example, the corresponding relationship between the current body movement and the third indicator score is shown in the following table:

[0128] Table 7 Query table of index scores of current limb movements

[0129] Current body movement The third indicator score Holding a mobile phone to make calls 1 Eating Actions 0.7 Control the central control screen 0.5 Organize items 0.3

[0130] When it is identified that the driver's current body movement is holding a mobile phone to make a call, the third indicator score can be determined to be 1 point; when it is identified that the driver's current body movement is tidying up items, the third indicator score can be determined to be 0.3 points.

[0131] S304, respectively obtaining the horizontal sight line offset angle, the vertical sight line offset time, and the weight coefficient of the current limb movement to obtain a first weight coefficient group;

[0132] Specifically, according to the influence of the horizontal deviation angle of the line of sight, the vertical deviation time of the line of sight and the current limb movement on the current fatigue level assessment, the corresponding weight coefficient is preset. The higher the weight coefficient, the greater the influence of the indicator on the current fatigue level assessment, and the lower the weight coefficient, the smaller the influence of the indicator on the current fatigue level assessment.

[0133] S305: Calculate a first score based on the first weight coefficient group, the first indicator score, the second indicator score, and the third indicator score;

[0134] Specifically, the first score can be calculated using the following formula:

[0135]

[0136] Among them, DSI is the first score; A is the first indicator score, B is the second indicator score, and C is the third indicator score. a, b, and c are the weight coefficients of the horizontal deviation angle of the line of sight, the vertical deviation time of the line of sight, and the current limb movement, respectively.

[0137] S306: Determine the current fatigue level based on the first score according to a preset correspondence between the score and the fatigue level.

[0138] For example, the fatigue level includes three levels: level one fatigue, level two fatigue, and level three fatigue. The corresponding relationship between the first score and each fatigue level can be shown in the following table:

[0139] Table 8 Current fatigue level query table

[0140] First Score (DSI) Current fatigue level (0.5,0.75] Level 3 fatigue (0.75,0.9] Secondary fatigue >0.9 Level 1 fatigue

[0141] When the calculated first score is 0.5 or less, it indicates that the driver is currently in a normal state and is not tired or distracted, that is, the head-up display function is a normal display, and the amount of displayed content is not reduced, nor is the area of ​​the display area reduced; when the calculated first score is in the interval of (0.5, 0.75], for example, 0.6, it can be determined that the current fatigue level is level 3 fatigue; when the calculated first score is in the interval of (0.75, 0.9], for example, 0.8, it can be determined that the current fatigue level is level 2 fatigue; when the calculated first score is greater than 0.9, for example, 0.95, it can be determined that the current fatigue level is level 1 fatigue.

[0142] The lateral deviation angle of the driver's line of sight (horizontal rotation of the head or eyes) is directly related to the driver's attention to key information on both sides of the road. Abnormal lateral angles usually indicate sudden distraction, such as looking down at a mobile phone or talking to a passenger. Such behaviors will instantly reduce the ability to perceive the road conditions ahead and significantly increase the risk of collision. Lateral movements (such as briefly glancing at the rearview mirror) are normal driving behaviors, and their duration is weakly correlated with risk. For example, lateral observation when changing lanes requires 1-2 seconds, but this is a safe operation. If the lateral duration is collected, it is easy to increase the possibility of misjudging normal behavior as distraction. The longitudinal deviation time of the driver's gaze (the duration of gaze drooping or looking up) reflects the driver's ability to maintain attention on the road ahead. When driving fatigued, the driver's muscles relax and their reactions are slow, which leads to an increase in the frequency of longitudinal gaze drooping and a prolonged period of each drooping. The occurrence of such behavior indicates that attention has shifted from the road environment to static targets in the car (such as mobile phones and seats). The longitudinal angle (such as the degree of head lowering) is usually greatly affected by individual differences such as seat height and driver height. Small head lowering may not pose a risk (such as adjusting the air conditioner). In comparison, the cumulative effect of longitudinal deviation time better reflects the gradual characteristics of fatigue.

[0143] Based on steps S301 to S306, a first score is calculated according to the first weight coefficient group, the first indicator score, the second indicator score and the third indicator score, thereby realizing the effective integration of three different dimensional indicators; at the same time, in the case of lateral deviation of the line of sight, the deviation angle is used as the evaluation indicator, and in the case of longitudinal deviation of the line of sight, the time is used as the evaluation indicator. On the one hand, the driver's sudden distraction and progressive fatigue can be effectively monitored, and the two together cover the most critical risk scenarios in driving safety; on the other hand, it can effectively reduce the possibility of misjudgment, improve the accuracy of the assessment of the driver's distraction and fatigue level, and provide an accurate judgment basis for the subsequent use of the current fatigue level to reduce the amount of displayed content and shrink the area of ​​the display area.

[0144] In different time periods or weather conditions, the influence of the horizontal sight offset angle, the vertical sight offset time, and the current body movement on driving safety varies. Therefore, the weight coefficients can be determined based on the weather information or time information of the current vehicle environment. In some embodiments, the weight coefficients of the horizontal sight offset angle, the vertical sight offset time, and the current body movement are obtained respectively to obtain a first weight coefficient group, including:

[0145] According to the weather information or time information of the current vehicle environment, the weight coefficients corresponding to the horizontal line of sight offset angle, the vertical line of sight offset time and the current limb movement are determined as the first weight coefficient group.

[0146] At night, when visibility is poor and fatigue is more likely, a higher weighting factor can be considered for the longitudinal gaze deviation duration, which primarily captures driver fatigue. During the day, when lighting is better and surrounding objects are clearly visible, attracting the driver's attention, a higher weighting factor can be considered for the lateral gaze deviation angle, which primarily captures driver distraction. In extreme weather conditions, such as rain, snow, and fog, drivers are often more nervous and less likely to experience fatigue. These conditions require the driver to be highly focused, and distraction can have a greater impact on driving safety. Therefore, a higher weighting factor can be considered for the lateral gaze deviation angle, which primarily captures driver distraction. By determining the weighting factors for the lateral gaze deviation angle, longitudinal gaze deviation duration, and current body movements based on the vehicle's current weather or time of day, the impact of different time and weather conditions on the driver's state can be fully accounted for. This allows the head-up display to more accurately reflect the current situation, reducing the amount of content displayed or the display area, thereby further improving driver safety.

[0147] Specifically, the correspondence between different weather or time and the horizontal deviation angle of sight, the vertical deviation time of sight and the weight coefficient of the current body movement is preset. For example, the correspondence between different weather information or time information and the horizontal deviation angle of sight, the vertical deviation time of sight and the weight coefficient of the current body movement is shown in the following table:

[0148] Table 9 Query table of weight coefficients of current action information under different weather information and time information

[0149]

[0150] The faster the vehicle speed and the worse the driving environment, the higher the driving risk level. Therefore, the driving risk level of the current vehicle can be effectively assessed based on the driving parameter information and the driving environment information. In some embodiments, the assessment of the driving risk level of the current vehicle based on the driving parameter information and the driving environment information includes:

[0151] S401, determining a corresponding fourth index score according to the driving parameter information;

[0152] Specifically, driving parameter information includes vehicle speed information. The faster the speed, the more dangerous the driving, and the higher the corresponding fourth index score. Vehicle speed information can be obtained directly from the vehicle's speed controller or from the vehicle's central control system, without limitation. A predetermined correspondence between driving parameter information and the fourth index score is established. Once specific vehicle speed information is obtained, the fourth index score can be calculated based on this correspondence.

[0153] For example, taking the driving parameter information including vehicle speed information as an example, the corresponding relationship between the driving parameter information and the fourth index score is shown in the following table:

[0154] Table 10 Index score query table of driving parameter information

[0155]

[0156] S402: Determine a corresponding fifth index score based on the driving environment information;

[0157] Specifically, driving environment information includes various information, including road curve radius, follow-up collision time, weather information, traffic density and other information. The road curve radius can be monitored by laser radar or wheel speed sensors, steering angle sensors, etc. installed around the vehicle, or it can be obtained by capturing images of lane lines or road boundaries with camera equipment and combining them with image processing algorithms. There are no specific restrictions. Follow-up collision time = relative distance between the current vehicle and the preceding vehicle ÷ relative speed difference between the current vehicle and the preceding vehicle. It can be detected by millimeter wave radar, laser radar and other equipment installed around the vehicle. There are no specific restrictions. Weather information includes light intensity and precipitation intensity. Light intensity and precipitation intensity can be monitored by light intensity sensors and rain sensors installed around the vehicle, or by other equipment capable of monitoring light intensity and precipitation intensity. There are no specific restrictions. Traffic density can be calculated using a camera device combined with a target detection algorithm. The camera device is used to capture images or video streams of the current vehicle's surroundings, and the target detection algorithm is used to identify the number of vehicles in the image or video stream. The traffic density is then calculated using the following formula: Traffic density = number of vehicles in the detection frame of the detection device / maximum detection number. The maximum detection number is a preset value that can be determined based on experience or historical data, and there is no specific restriction.

[0158] The corresponding relationship between various types of driving environment information and the fifth index score is preset. For example, the corresponding relationship between various types of driving environment information and the fifth index score is shown in the following table:

[0159] Table 11 Driving environment information index score query table

[0160]

[0161]

[0162] Among them, the detection range of the road curve radius is (50m, 500m), and the road curve radius R is mapped to the range of 0 to 1 through min(1, 100 / R). The value mapped to the range of 0 to 1 is the fifth indicator score corresponding to the road curve radius.

[0163] S403, respectively obtaining weight coefficients corresponding to the driving parameter information and the driving environment information to obtain a second weight coefficient group;

[0164] Specifically, according to the degree of influence of various driving parameter information and various driving environment information on driving hazards, corresponding weight coefficients are preset. The higher the weight coefficient, the greater the influence of the indicator on the assessment of the driving hazard level, and the lower the weight coefficient, the smaller the influence of the indicator on the assessment of the driving hazard level.

[0165] S404: Calculate a second score based on the second weight coefficient group, the fourth indicator score, and the fifth indicator score;

[0166] Specifically, the second score can be calculated using the following formula:

[0167]

[0168] Among them, DSI is the second score; D is the fourth index score of vehicle speed information, F is the fifth index score of road curve radius, G is the fifth index score of vehicle follow-up collision time, H is the fifth index score of weather information, and L is the fifth index score of traffic density; d, f, g, h, and i are the weight coefficients of vehicle speed information, road curve radius, vehicle follow-up collision time, weather information, and traffic density, respectively.

[0169] S405: Determine the driving risk level based on the second score according to a preset correspondence between the score and the risk level.

[0170] For example, taking the three danger levels including level one danger, level two danger, and level three danger as an example, the corresponding relationship between the first score and the driving danger level can be shown in the following table:

[0171] Table 12 Driving Hazard Level Query Table

[0172] First Score (DSRI) Driving hazard level (0.5,0.75] Level 3 danger (0.75,0.9] Level 2 danger >0.9 Level 1 danger

[0173] When the calculated second score is 0.5 or less, it indicates that the current driving safety is relatively high and the head-up display function can be displayed normally; when the calculated second score is in the range of (0.5, 0.75], for example, 0.7, it can be determined that the driving hazard level is level three; when the calculated second score is in the range of (0.75, 0.9], for example, 0.85, it can be determined that the driving hazard level is level two; when the calculated first score is greater than 0.9, for example, 0.96, it can be determined that the driving hazard level is level one.

[0174] Based on steps S401 to S405, the second score is calculated according to the second weight coefficient group, the fourth indicator score and the fifth indicator score, thereby realizing the integration of multiple driving parameter information and multiple driving environment information, fully considering the impact of various factors on driving safety, and effectively improving the assessment accuracy of the driving hazard level, providing an accurate judgment basis for the subsequent use of the driving hazard level to reduce the amount of displayed content and reduce the area of ​​the display area.

[0175] In different driving scenarios, the degree of influence of various types of driving parameter information and various types of driving environment information on driving safety varies to a certain extent, so the weight coefficient can be determined according to the type of scenario the vehicle is currently in. In some embodiments, the weight coefficients corresponding to the driving parameter information and the driving environment information are obtained separately, including:

[0176] The weight coefficients corresponding to the driving parameter information and the driving environment information are determined respectively according to the scene type in which the vehicle is currently located.

[0177] Specifically, scene types include urban roads, highways, mountainous areas and other situations. They can be analyzed and judged through navigation information, or by obtaining surrounding environment information through camera equipment, and the scene type can be further analyzed and judged based on the surrounding environment information. There is no specific restriction.

[0178] Urban roads generally have higher traffic density and lower speeds. Higher speeds significantly increase the risk of accidents on densely populated urban roads. Therefore, in urban road scenarios, the weighting factor for traffic density can be appropriately reduced, while the weighting factor for speed information can be increased. On highways, where speeds are typically higher, maintaining a higher weighting factor for speed information may result in a consistently high second score, increasing the likelihood of misjudgment. Therefore, in highway scenarios, the weighting factor for speed information can be appropriately reduced, while the weighting factors for weather information and other factors can be increased. Mountainous roads are complex and have many curves, requiring a lower speed. Changes in speed or weather significantly impact driving safety. Therefore, in mountainous scenarios, the weighting factors for speed, weather, and traffic density can be appropriately increased, while the weighting factors for curve radius and follow-up collision time can be appropriately reduced. In this application, the weight coefficients of various driving parameter information and various driving environment information are set according to different scene types, so that the assessment of driving hazard level can fully consider the characteristics of various scene types and effectively improve the accuracy of driving hazard level assessment.

[0179] The corresponding relationship between the weight coefficients of various types of driving parameter information and various types of driving environment information under different scene types is preset. For example, the corresponding relationship between the weight coefficients of various types of driving parameter information and various types of driving environment information is shown in the following table:

[0180] Table 13 Query table of weight coefficients of driving parameter information and driving environment information in different scene types

[0181]
