Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and more specifically, to a method, device, vehicle, and storage medium for adjusting a vehicle headlamp in the field of vehicle control technology. Background Art

[0002] Traditional headlamp adjustment methods include manual adjustment and passive adjustment based on vehicle load. Manual adjustment requires the driver to estimate the headlamp height based on experience before driving, while passive adjustment based on vehicle load can only roughly adjust the headlamp height based on the vehicle's load. However, for users who need to travel long distances at night or drive in low visibility conditions, unreasonable headlamp height can seriously affect nighttime driving safety. Therefore, how to improve driving safety has become an urgent problem that needs to be solved. Summary of the Invention

[0003] The present application provides a method, device, vehicle and storage medium for adjusting the headlights of a vehicle, which improves driving safety while meeting the driver's vision requirements.

[0004] In a first aspect, a method for adjusting the headlights of a vehicle is provided, the method comprising: obtaining a driver's concentration level on driving the vehicle; wherein the driving concentration level indicates whether the driver is in a fatigued driving state or a focused driving state; and adjusting the height of the headlight according to the driving concentration level; wherein the illumination area of the headlight after the height adjustment can cover the driver's field of view at the driving concentration level.

[0005] The above technical solution obtains the driver's driving concentration level and automatically and in real time adjusts the height of the headlights accordingly. The driving concentration level reflects the driver's concentration level while driving the vehicle. Since the driver's field of vision is different when he is in a fatigued driving state or a focused driving state, the height of the headlights needs to be adjusted in real time according to the driver's driving concentration level, so that the lighting area of the headlights after height adjustment can cover the driver's field of vision as much as possible when he is in a fatigued driving state or a focused driving state, thereby ensuring that the driver can obtain the best lighting field of vision under different driving concentration levels. It can not only improve the driver's driving safety, but also improve driving comfort, and provide the driver with safer and more reliable lighting support when driving at night.

[0006] In combination with the first aspect, in some possible implementations, adjusting the height of the headlights according to the degree of driving concentration includes: if the degree of driving concentration indicates that the driver is in a fatigued driving state, obtaining the driver's fatigue level; and lowering the height of the headlights according to the fatigue level.

[0007] The above technical solution identifies driver fatigue by assessing the driver's level of concentration and adjusts the headlamp height accordingly. When a driver is determined to be fatigued, indicating a lowered head position, the headlamp height is adjusted accordingly based on the driver's fatigue level to enhance near-field illumination and ensure the headlamp illumination area covers the fatigued driver's field of view, thereby reducing traffic accidents caused by driver misalignment and improving driving safety.

[0008] In combination with the first aspect and the above-mentioned implementation manner, in some possible implementation manners, obtaining the driver's fatigue level includes: obtaining the driver's head tilt angle, blinking frequency, and eye closure duration; determining that the driver's fatigue level is mild fatigue when the head tilt angle is greater than or equal to a first angle threshold and less than a second angle threshold, the blinking frequency is less than a first frequency threshold, and the eye closure duration is greater than a first duration threshold; determining that the driver's fatigue level is moderate fatigue when the head tilt angle is greater than or equal to the second angle threshold and less than a third angle threshold, the blinking frequency is less than a second frequency threshold, and the eye closure duration is greater than a second duration threshold; determining that the driver's fatigue level is severe fatigue when the head tilt angle is greater than or equal to the third angle threshold, the blinking frequency is less than a third frequency threshold, and the eye closure duration is greater than a third duration threshold; wherein the first angle threshold is less than the second angle threshold, and the second angle threshold is less than the third angle threshold; the first frequency threshold is greater than the second frequency threshold, and the second frequency threshold is greater than the third frequency threshold; the first duration threshold is less than the second duration threshold, and the second duration threshold is less than the third duration threshold.

[0009] The above technical solution analyzes the driver's head state information by setting different levels of fatigue determination criteria, thereby accurately assessing the driver's fatigue level. Specifically, three levels of fatigue (mild fatigue, moderate fatigue, and severe fatigue) are set based on three factors: head tilt angle, blink frequency, and eye closure duration. When analyzing the head tilt angle, three angle thresholds are preset: a first angle threshold, a second angle threshold, and a third angle threshold. These three angle thresholds gradually increase, indicating that the greater the head tilt angle, the greater the level of fatigue. When analyzing the blink frequency, three frequency thresholds are preset: a first frequency threshold, a second frequency threshold, and a third frequency threshold. These three frequency thresholds gradually decrease, indicating that the lower the blink frequency, the greater the level of fatigue. When analyzing the eye closure duration, three duration thresholds are preset: a first duration threshold, a second duration threshold, and a third duration threshold. These three duration thresholds gradually decrease, indicating that the longer the eye closure duration, the greater the level of fatigue. Using the three factors of head tilt angle, blinking frequency and eye closure duration to determine the level of fatigue can not only detect signs of driver fatigue in a timely manner, but also improve the accuracy of determining the level of fatigue.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the height of the headlight is lowered and adjusted according to the fatigue level, including: if the fatigue level is mild fatigue, the height of the headlight is lowered by a first height; if the fatigue level is moderate fatigue, the height of the headlight is lowered by a second height; if the fatigue level is severe fatigue, the height of the headlight is lowered by a third height; wherein the first height is less than the second height, and the second height is less than the third height.

[0011] The above technical solution adjusts the headlamp height in stages based on the driver's fatigue level to accommodate driving needs under different fatigue conditions. As driver fatigue increases, the driver's head gradually lowers. Failure to promptly adjust the headlamp height to align the headlamp's illuminated area with the driver's field of vision can cause a traffic accident. Therefore, as the driver's fatigue level increases and their head lowers, it is advisable to gradually lower the headlamp height so that the headlamp's illuminated area covers the driver's field of vision, providing maximum lighting support and ensuring driving safety.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, adjusting the height of the headlights according to the degree of driving concentration includes: if the degree of driving concentration indicates that the driver is in a focused driving state, obtaining the driver's eye height; and adjusting the height of the headlights according to the eye height.

[0013] The above technical solution uses the driver's eye level information from their head state to adjust the headlamp height to accommodate the driver's vision needs when they are focused on driving. When the driver's driving concentration level indicates that they are focused on driving, their eye level may change at any time. In this case, it is necessary to promptly obtain the driver's eye level information and accurately adjust the headlamp height based on this information to ensure that the illuminated area covers the driver's field of vision at eye level. This ensures that the headlamp lighting effect is more tailored to the driver's driving needs, effectively preventing traffic accidents caused by unclear vision and improving driving safety.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, adjusting the height of the headlights according to the degree of driving concentration includes: obtaining the maximum safe height and the minimum safe height of the headlights; determining the adjusted height of the headlights according to the degree of driving concentration; if the adjusted height is greater than or equal to the minimum safe height and less than or equal to the maximum safe height, adjusting the height of the headlights based on the adjusted height.

[0015] The above technical solution, by setting the maximum safe height and minimum safe height of the headlights, can ensure that the headlights are always adjusted within the safe operating range, providing the driver with more suitable lighting conditions, effectively improving the driving experience and driving safety, and can avoid traffic accidents caused by improper lighting area of the headlights due to improper height adjustment.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method further includes: if the adjusted height is less than the minimum safety height, adjusting the height of the headlight based on the minimum safety height; if the adjusted height is greater than the maximum safety height, adjusting the height of the headlight based on the maximum safety height.

[0017] In the above technical solution, when the height of the headlights after adjustment is less than the minimum safe height, the driver may not be able to see the road conditions in the distance because the headlights are too low. In order to ensure that the driver has sufficient vision at night or under conditions of low visibility, the height of the headlights can be adjusted according to the minimum safe height to improve driving safety; when the height of the headlights after adjustment is greater than the maximum safe height, the driver may not be able to see the road conditions in the near distance because the headlights are too high. In order to further ensure that the driver has sufficient vision at night or under conditions of low visibility, the height of the headlights can be adjusted according to the maximum safe height to further improve driving safety. This method not only meets the needs of dynamic and real-time adjustment of the headlights, but also ensures the lighting effect and safety of the headlights, providing the driver with a more comfortable and safe driving environment.

[0020] In combination with the second aspect and the above-mentioned implementation manner, in some implementation manners of the second aspect, the adjustment module is specifically used to: obtain the driver's fatigue level, including: obtaining the driver's head tilt angle, blinking frequency, and eye closure duration; determining that the driver's fatigue level is mild fatigue when the head tilt angle is greater than or equal to a first angle threshold and less than a second angle threshold, the blinking frequency is less than the first frequency threshold, and the eye closure duration is greater than the first duration threshold; determining that the driver's fatigue level is moderate fatigue when the head tilt angle is greater than or equal to the second angle threshold and less than a third angle threshold, the blinking frequency is less than the second frequency threshold, and the eye closure duration is greater than the second duration threshold; determining that the driver's fatigue level is severe fatigue when the head tilt angle is greater than or equal to the third angle threshold, the blinking frequency is less than the third frequency threshold, and the eye closure duration is greater than the third duration threshold; wherein the first angle threshold is less than the second angle threshold, and the second angle threshold is less than the third angle threshold; the first frequency threshold is greater than the second frequency threshold, and the second frequency threshold is greater than the third frequency threshold; the first duration threshold is less than the second duration threshold, and the second duration threshold is less than the third duration threshold.

[0021] In combination with the second aspect and the above-mentioned implementation methods, in certain implementation methods of the second aspect, the adjustment module is specifically used to: lower the height of the headlight according to the fatigue level, including: if the fatigue level is mild fatigue, lowering the height of the headlight by a first height; if the fatigue level is moderate fatigue, lowering the height of the headlight by a second height; if the fatigue level is severe fatigue, lowering the height of the headlight by a third height; wherein, the first height is less than the second height, and the second height is less than the third height.

[0032] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] Traditional headlamp adjustment methods include manual adjustment and passive adjustment based on vehicle load. Manual adjustment requires the driver to estimate the headlamp height based on experience before driving, while passive adjustment based on vehicle load can only roughly adjust the headlamp height based on the vehicle's load. However, for users who need to travel long distances at night or drive in low visibility conditions, improper headlamp height can seriously affect nighttime driving safety. Specifically, when the headlamp height is too high, the road surface near the driver is insufficiently illuminated, making it difficult for the driver to clearly see nearby obstacles. When the headlamp height is too low, the road conditions in the distance are unclear, making it difficult for the driver to make timely judgments at high speeds. Therefore, improving driving safety has become a pressing issue.

[0035] To at least solve the above problems, an embodiment of the present application provides a method for adjusting the headlights of a vehicle, which is applied to the vehicle controller of the vehicle. The method improves driving safety while meeting the driver's vision requirements.

[0036] Figure 1 This is a schematic flowchart of a method for adjusting a vehicle headlamp provided in an embodiment of the present application.

[0037] For example, Figure 1 As shown, the method 100 includes:

[0038] Step 101: Acquire the driver's driving concentration level on the vehicle; wherein the driving concentration level indicates whether the driver is in a fatigue driving state or a focused driving state.

[0039] Step 102 : adjusting the height of the headlights according to the driver's driving concentration level; wherein the lighting area of the headlights after the height adjustment can cover the driver's field of view under the driver's driving concentration level.

[0040] In an embodiment of the present application, the driver's driving concentration level is obtained and the height of the headlights is automatically and real-time adjusted accordingly. The driving concentration level reflects the driver's concentration level while driving the vehicle. The driver's field of view varies under different driving concentration levels. Whether the driver's field of view can be illuminated is affected by the height of the headlights. Therefore, the height of the headlights is adjusted according to the driving concentration level so that the lighting area of the headlights covers the driver's field of view as much as possible, thereby ensuring that the driver can obtain the best lighting field of view under different driving concentration levels. This can not only improve the driver's driving safety, but also improve driving comfort, and provide the driver with safer and more reliable lighting support when driving at night.

[0041] Below Figure 1 The implementation of each step in the embodiment shown is described in detail.

[0042] Regarding step 101 , it is understandable that when obtaining the driver's concentration level on the vehicle, the driver's head state information may be obtained, and the driver's concentration level on the vehicle may be determined based on the driver's head state information.

[0043] In some embodiments, the driver's head state information is obtained; and the driver's concentration level on the vehicle is determined based on the head state information.

[0044] It is understandable that the above-mentioned head state information is used to describe the state of the driver's head in the car, and may include the head tilt angle, blinking frequency, eye closing time and eyeball height.

[0045] Obtaining the driver's head tilt angle, blink frequency, eye closure duration, and eye height mainly relies on the Driver Monitoring System (DMS) in modern automobile safety systems.

[0046] In actual applications, the vehicle controller sends instructions to the DMS through the vehicle's internal communication network (for example, the Controller Area Network (CAN)). After receiving the instructions, the DMS obtains the driver's head status information.

[0047] The head tilt angle refers to the degree of tilt of the head relative to a reference plane, which can be a horizontal plane or a plane perpendicular to the horizontal plane. When obtaining the driver's head tilt angle, the DMS captures the driver's facial image through the in-car camera and inputs the facial image into a convolutional neural network (CNN). The CNN extracts features from the image layer by layer (including but not limited to facial contours, eyes, nose, mouth, etc.) and calculates the head pitch angle based on these features. The pitch angle reflects the up and down tilt angle of the head.

[0048] The blink frequency refers to the number of blinks per unit time, usually calculated per minute. To determine the driver's blink frequency, the DMS uses an in-car camera to capture images of the driver's eyes. It then uses a pre-defined eye fatigue detection algorithm to analyze the eye opening and closing states in these images. The blink frequency is then calculated by counting the number of blinks per unit time.

[0049] The above-mentioned eye closure duration refers to the duration of eye closure, that is, the time from the time the eyes begin to close to the time they reopen. To obtain the driver's eye closure duration, the DMS captures the driver's eye images through the in-vehicle camera and uses a preset eye fatigue detection algorithm to analyze the eye opening and closing status in the eye images. The eye closure duration is calculated by recording the length of each eye closure.

[0050] Eye height refers to the vertical distance between the center of a person's eye and the ground when they are seated and looking straight ahead. To determine the driver's eye height, the DMS uses an in-car camera to capture the driver's facial image and identify the position of their eyes. This eye position is then mapped into three-dimensional space and, combined with the head tilt angle, is used to calculate the height of the eye relative to the ground.

[0051] The DMS sends the acquired driver's head state information back to the vehicle controller, which uses this information to determine the driver's level of focus. This level of focus can be used to characterize the driver's current state, including fatigue and focused driving.

[0052] When the driver has a relatively fixed sitting posture (i.e., the head posture is relatively fixed), the driver's eyes are fixed on the road ahead, and the driver's blinking frequency is within a normal range, it means that the driver is currently in a state of focused driving.

[0053] When the driver's head is tilted, the driver closes his eyes for a long time and the driver blinks slowly, it means that the driver is currently in a fatigue driving state.

[0054] Regarding step 102 , it can be understood that when the driver is in different fatigue states, the vehicle controller adjusts the height of the vehicle headlights to different degrees.

[0055] Specifically, when the driver is in a state of fatigue driving, the driver may have his head tilted forward, and due to the forward tilt of the driver's head, the driver's field of vision also changes to a certain extent. At this time, the lighting area of the headlights at the original height can no longer cover the driver's current field of vision. Therefore, it is possible to consider lowering the height of the headlights so that the lighting area of the headlights after the height adjustment can cover the driver's current field of vision. When the driver is in a state of focused driving, the driver's eye height will change in real time according to the driving conditions of the vehicle. When the driver's eye height changes, if the headlight height is not adjusted in time, the lighting area of the headlights at the original height may not cover the driver's current field of vision. Therefore, it is possible to consider adjusting the height of the headlights in real time according to the driver's eye height so that the lighting area of the headlights after the height adjustment can cover the driver's current field of vision.

[0056] In some embodiments, the height of the headlights is adjusted according to the degree of driving concentration, including: if the degree of driving concentration indicates that the driver is in a fatigued driving state, obtaining the driver's fatigue level; and lowering the height of the headlights according to the fatigue level.

[0057] It can be understood that the above fatigue levels can include mild fatigue, moderate fatigue and severe fatigue. When determining the driver's fatigue level, it can be determined based on the driver's head state information, and the height of the vehicle headlights can be lowered to varying degrees according to the fatigue level.

[0058] The system identifies driver fatigue by assessing the driver's concentration and adjusts the headlight height accordingly. When a driver is judged to be fatigued, indicating a lowered head position, the headlight height is adjusted accordingly to enhance near-field illumination and ensure the headlights illuminate the driver's field of vision. This reduces traffic accidents caused by driver misalignment and improves driving safety.

[0059] The following describes in detail the process of determining the driver's fatigue level based on the driver's head state information:

[0060] In some embodiments, obtaining the driver's fatigue level includes: obtaining the driver's head tilt angle, blinking frequency and eye closure duration; when the head tilt angle is greater than or equal to a first angle threshold and less than a second angle threshold, the blinking frequency is less than the first frequency threshold and the eye closure duration is greater than the first duration threshold, determining that the driver's fatigue level is mild fatigue; when the head tilt angle is greater than or equal to the second angle threshold and less than a third angle threshold, the blinking frequency is less than the second frequency threshold and the eye closure duration is greater than the second duration threshold, determining that the driver's fatigue level is moderate fatigue; when the head tilt angle is greater than or equal to the third angle threshold, the blinking frequency is less than the third frequency threshold and the eye closure duration is greater than the third duration threshold, determining that the driver's fatigue level is severe fatigue; wherein, the first angle threshold is less than the second angle threshold, the second angle threshold is less than the third angle threshold; the first frequency threshold is greater than the second frequency threshold, the second frequency threshold is greater than the third frequency threshold; the first duration threshold is less than the second duration threshold, and the second duration threshold is less than the third duration threshold.

[0061] It is understandable that the above-mentioned first angle threshold, second angle threshold and third angle threshold can be pre-calibrated to indicate the current degree of head tilt of the driver. When the driver is in a fatigued driving state, the head tilt angle is used to refer to the angle at which the head is tilted forward or drooped. The greater the degree of head tilt, the more severe the fatigue. Optionally, the first angle threshold can be calibrated to 10°~15°, the second angle threshold can be calibrated to 15°~25°, and the third angle threshold can be calibrated to 25°~30°.

[0062] The first, second, and third frequency thresholds can be pre-calibrated to indicate the driver's current blink frequency. Lower blink rates indicate greater fatigue. Optionally, the first frequency threshold can be calibrated to 10 to 15 blinks / minute, the second frequency threshold can be calibrated to 5 to 10 blinks / minute, and the third frequency threshold can be calibrated to 0 to 5 blinks / minute.

[0063] The first, second, and third duration thresholds can be pre-calibrated to indicate the driver's current level of fatigue. The longer the eyes are closed, the greater the level of fatigue. Optionally, the first duration threshold can be calibrated to 1 to 1.5 seconds, the second duration threshold can be calibrated to 1.5 to 2 seconds, and the third duration threshold can be calibrated to 2 to 2.5 seconds.

[0064] In the case of a driver experiencing fatigue, the head tilt angle can capture the driver's gradual lowering of their head due to sleepiness. Therefore, when the driver tilts their head due to fatigue, the head tilt angle can reflect the driver's fatigue level. In other words, the head tilt angle can be used to determine the driver's fatigue level. Blinking frequency can directly reflect the driver's fatigue level. Therefore, when the driver's blinking frequency decreases due to fatigue, the blinking frequency can reflect the driver's fatigue level. Furthermore, eye closure duration can directly reflect the driver's fatigue level. Therefore, when the driver's eye closure duration increases due to fatigue, the eye closure duration can also reflect the driver's fatigue level. These parameters complement each other, reducing the uncertainty caused by fluctuations in a single parameter. For example, even if a driver's head tilt occurs, it does not necessarily mean that the driver is fatigued. In this case, the eye state information can be combined to distinguish head tilt caused by other factors from head tilt caused by fatigue, thus avoiding misjudgment. Determining the driver's fatigue level through multi-dimensional head status information classification can not only significantly improve the accuracy and reliability of fatigue detection, but also effectively reduce the false alarm rate.

[0065] The above technical solution analyzes the driver's head status information by setting different levels of fatigue judgment standards, so as to accurately assess the driver's fatigue level, and uses three factors: head tilt angle, blinking frequency and eye closure time to determine the level of fatigue. It can not only detect signs of driver fatigue in a timely manner, but also improve the accuracy of determining the level of fatigue.

[0066] In actual application, when the driver nods more frequently or yawns occasionally, it can be determined that the driver's fatigue level is moderate fatigue; when the driver shakes his head more frequently and with greater amplitude and yawns frequently, it can be determined that the driver's fatigue level is severe fatigue.

[0067] In some embodiments, the height of the headlights is lowered and adjusted according to the degree of fatigue, including: if the degree of fatigue is mild, the height of the headlights is lowered by a first height; if the degree of fatigue is moderate, the height of the headlights is lowered by a second height; if the degree of fatigue is severe, the height of the headlights is lowered by a third height; wherein the first height is less than the second height, and the second height is less than the third height.

[0068] It will be appreciated that the first, second, and third heights described above all represent the heights to which the headlights need to be lowered. When the driver's fatigue level is mild, the vehicle controller lowers the headlight height by a first height from the current height; when the driver's fatigue level is moderate, the vehicle controller lowers the headlight height by a second height from the current height; and when the driver's fatigue level is severe, the vehicle controller lowers the headlight height by a third height from the current height.

[0069] The above technical solution adjusts the headlamp height in stages based on the driver's fatigue level to accommodate driving needs under different fatigue conditions. As driver fatigue increases, the driver's head gradually lowers. Failure to promptly adjust the headlamp height to align the headlamp's illuminated area with the driver's field of vision can cause a traffic accident. Therefore, as the driver's fatigue level increases and their head lowers, it is advisable to gradually lower the headlamp height so that the headlamp's illuminated area covers the driver's field of vision, providing maximum lighting support and ensuring driving safety.

[0070] In actual application, considering that the driver's fatigue level gradually increases, the height of the headlights can also be adjusted as follows:

[0071] When the driver's fatigue level is mild, the vehicle controller lowers the height of the headlights by a first height based on concentrating on driving (i.e., lowers the first height based on the current height of the headlights), so that the height of the headlights reaches the first target height; when the driver's fatigue level is moderate, the vehicle controller lowers the height of the headlights by a second height based on mild fatigue (i.e., lowers the second height based on the first target height), so that the height of the headlights reaches the second target height; when the driver's fatigue level is severe, the vehicle controller lowers the height of the headlights by a third height based on moderate fatigue (i.e., lowers the third height based on the second target height), or lowers the height of the headlights by a third height based on mild fatigue (i.e., lowers the third height based on the first target height).

[0072] Different headlamp lowering heights correspond to different fatigue levels. This design aims to dynamically adjust the headlamp lighting effect in real time based on the driver's head position to ensure driving safety. To achieve this function and continuously optimize the headlamp adjustment results, the headlamp lowering height can be adjusted while the vehicle is parked using the following steps.

[0073] Specifically, when the vehicle is parked, the vehicle controller can utilize this relatively static state to more accurately acquire the driver's head position information. After acquiring this head position information, it uses a deep learning-based image recognition algorithm and a machine learning-based classification model to perform a detailed analysis and assessment of the driver's fatigue level. Based on the assessed fatigue level, the vehicle controller adjusts the headlight lowering height accordingly. This adjustment is based on a pre-set relationship between fatigue level and lowering height, ensuring that the headlights provide the most appropriate lighting effect at varying fatigue levels. To achieve more optimal headlight adjustment results, the vehicle controller can also perform multiple tests and adjustments while the vehicle is parked. By continuously acquiring the driver's head position information and fine-tuning the lowering height, the optimal headlight adjustment solution for the current driver is gradually optimized. For example, when the driver's head position information indicates mild fatigue, multiple headlight heights for the same driver at different eye heights are acquired and averaged to obtain the final first height. The fine-tuning method of the second height and the third height is the same as the fine-tuning method of the first height, so it will not be repeated here.

[0074] Furthermore, the vehicle can also be equipped with a self-learning function. During long-term use, the vehicle controller continuously accumulates driving data and adjustment data, allowing it to more accurately judge the driver's fatigue level and more precisely adjust the height of the headlights.

[0075] In summary, by acquiring head position information from multiple drivers while the vehicle is parked and continuously adjusting the headlight lowering height, more reasonable headlight adjustment results can be achieved, improving not only driving safety but also driving comfort and convenience.

[0076] In some embodiments, the height of the headlights is adjusted according to the degree of driving concentration, including: if the degree of driving concentration indicates that the driver is in a focused driving state, obtaining the driver's eye height; and adjusting the height of the headlights according to the eye height.

[0077] It is understood that when the driver is focused on driving, the vehicle controller determines the headlamp height based on the driver's eye height by querying a preset correspondence relationship. The preset correspondence relationship describes the relationship between the driver's eye height and the headlamp height. In the preset correspondence relationship, the driver's eye height and the headlamp height are positively correlated.

[0078] For ease of understanding, and considering that eye height is the vertical distance between the eye and the ground, the height of the headlamp can be considered to be defined as the vertical distance between the headlamp and the ground.

[0079] In the above correspondence, as the eyeball height increases, the vertical distance between the eyes and the ground also gradually increases. In order to enable the driver to see the road conditions in the distance clearly, it is possible to consider raising the height of the headlights, that is, increasing the vertical distance between the headlights and the ground.

[0080] In the above technical solution, when the driving concentration level indicates that the driver is concentrating on driving, the driver's eye height may change at any time. At this time, it is necessary to obtain the driver's eye height information in a timely manner and accurately adjust the height of the headlights according to the eye height information to ensure that the illuminated area of the headlights covers the driver's eye height field of view, so that the lighting effect of the headlights is more in line with the driver's driving needs, thereby effectively preventing traffic accidents caused by unclear vision and improving driving safety.

[0081] When establishing the preset correspondence, ensuring the security of the data acquisition process is crucial. To accurately and safely set the correspondence between different drivers' eyeball heights and headlamp heights, consider performing this data collection and setting process while the vehicle is parked. The following details the above process:

[0082] First, select the parked state for data collection. When the vehicle is parked, it remains stationary, ensuring stability during data collection and avoiding inaccurate data due to vehicle movement or external interference while driving. Furthermore, while parked, the driver can adjust their sitting posture in a relaxed environment, more realistically reflecting their daily driving habits.

[0083] Second, eye height is collected based on the sitting posture of different drivers. Considering the differences in height, body shape, and driving habits of each driver, their sitting posture will also vary. Therefore, eye height data needs to be collected separately for each driver. During the collection process, an on-board camera or a dedicated eye tracking device can be used to accurately measure the driver's eye height. To ensure the accuracy of the data, eye height data of multiple drivers in different sitting postures can be obtained, and the eye height data of multiple different sitting postures can be averaged to obtain multiple different eye heights.

[0084] Third, different headlamp heights are set for different eye levels. Based on the eye level data obtained above, multiple headlamp heights are set for each driver. These heights ensure that the headlamp light accurately illuminates the road ahead in different driver postures, providing optimal lighting.

[0085] Finally, the collected eye-height data is mapped to the headlamp height settings to create a preset mapping table. This mapping table can be stored in the vehicle's electronic control unit, allowing for automatic headlamp height adjustment based on the driver's eye height during actual driving. To verify the accuracy of this mapping, a simulation test can be conducted while the vehicle is parked. By adjusting the driver's sitting position and eye height, the system can be used to observe whether the headlamp light accurately illuminates the road ahead. Fine-tuning the mapping table can then be performed based on the test results.

[0086] In summary, by collecting eyeball height data based on the driver's different sitting postures when the vehicle is parked and setting different headlight heights for different eyeball heights, an accurate and safe preset correspondence is established. This not only improves driving comfort and safety, but also meets the driver's personalized needs.

[0087] In order to prevent the headlights from being too high or too low, thereby affecting the driver's driving safety, it is possible to consider presetting the maximum and minimum heights that the headlights can adjust to improve driving safety.

[0088] In some embodiments, the height of the headlights is adjusted according to the degree of driving concentration, including: obtaining the maximum safe height and the minimum safe height of the headlights; determining the adjusted height of the headlights according to the degree of driving concentration; if the adjusted height is greater than or equal to the minimum safe height and less than or equal to the maximum safe height, adjusting the height of the headlights based on the adjusted height.

[0089] It can be understood that the above-mentioned maximum safe height of the headlight refers to the highest vertical distance between the headlight and the ground, and the above-mentioned minimum safe height refers to the lowest vertical distance between the headlight and the ground. The above-mentioned maximum safe height and minimum safe height are both preset values.

[0090] When the driver is in a fatigued driving state, after the vehicle controller obtains the height to which the headlights need to be lowered, it calculates the difference between the current height of the headlights and the height to which they need to be lowered, and obtains the adjusted height of the headlights. If the adjusted height is greater than or equal to the minimum safe height, the vehicle controller controls the headlights to be lowered to the adjusted height.

[0091] When the driver is concentrating on driving, after the vehicle controller obtains the adjusted height of the headlights, it determines whether the adjusted height of the headlights is between the minimum safe height and the maximum safe height. If the adjusted height of the headlights is between the minimum safe height and the maximum safe height, the vehicle controller controls the headlights to adjust to the adjusted height.

[0092] The above technical solution, by setting the maximum safe height and minimum safe height of the headlights, can ensure that the headlights are always adjusted within the safe operating range, providing the driver with more suitable lighting conditions, effectively improving the driving experience and driving safety, and can avoid traffic accidents caused by improper lighting area of the headlights due to improper height adjustment.

[0093] In some embodiments, the method further includes: if the adjusted height is less than the minimum safe height, adjusting the height of the headlight based on the minimum safe height; if the adjusted height is greater than the maximum safe height, adjusting the height of the headlight based on the maximum safe height.

[0094] It is understandable that if the adjusted height is less than the minimum safe height, it means that the adjusted height is too low, making it difficult for the driver to see the road conditions in the distance. Considering driving safety, the vehicle controller needs to adjust the height of the headlights based on the minimum safe height; if the adjusted height is higher than the maximum safe height, it means that the adjusted height is too high, making it difficult for the driver to see nearby obstacles. Considering driving safety, the vehicle controller needs to adjust the height of the headlights based on the maximum safe height.

[0095] In the above technical solution, when the height of the headlights after adjustment is less than the minimum safe height, the driver may not be able to see the road conditions in the distance because the headlights are too low. In order to ensure that the driver has sufficient vision at night or under conditions of low visibility, the height of the headlights can be adjusted according to the minimum safe height to improve driving safety; when the height of the headlights after adjustment is greater than the maximum safe height, the driver may not be able to see the road conditions in the near distance because the headlights are too high. In order to further ensure that the driver has sufficient vision at night or under conditions of low visibility, the height of the headlights can be adjusted according to the maximum safe height to further improve driving safety. This method not only meets the needs of dynamic and real-time adjustment of the headlights, but also ensures the lighting effect and safety of the headlights, providing the driver with a more comfortable and safe driving environment.

[0096] Figure 2 This is a schematic flowchart of another method for adjusting vehicle headlights provided in an embodiment of the present application.

[0097] For example, Figure 2 As shown, the method 200 includes:

[0098] Step 201: Acquire the driver's head status information.

[0099] Step 202: Determine the driver's concentration on driving the vehicle based on the head state information.

[0100] Step 203: Determine whether the driving concentration level indicates that the driver is in a state of focused driving. If yes, proceed to step 204; otherwise, proceed to step 207.

[0101] Step 204: Determine whether the driver is focused on driving.

[0102] Step 205: Obtain the driver's eye height.

[0103] Step 206 : According to the driver's eyeball height, a preset corresponding relationship is searched to obtain the height of the headlight after adjustment.

[0104] Step 207: Determine whether the driver is in a fatigue driving state.

[0105] Step 208: Determine the driver's fatigue level based on the head status information.

[0106] Step 209: Determine the height to which the headlights need to be lowered based on the driver's fatigue level.

[0107] Step 210 : determining the adjusted height of the headlights based on the current height of the headlights and the height to which the headlights need to be lowered.

[0108] Step 211: Determine whether the adjusted altitude is between the minimum safe altitude and the maximum safe altitude. If so, proceed to step 212; otherwise, proceed to step 213.

[0109] Step 212 : Adjust the height of the headlight based on the adjusted height.

[0110] Step 213: Determine whether the adjusted height is less than the minimum safe height. If so, proceed to step 214; otherwise, proceed to step 215.

[0111] Step 214 : Adjust the height of the headlights based on the minimum safe height.

[0112] Step 215 : Adjust the height of the headlights based on the maximum safe height.

[0113] For step 212, step 214 and step 215, the vehicle controller outputs the adjusted height, minimum safe height or maximum safe height to the headlight execution module, which includes a motor and a ball screw, etc. When the motor controller receives a height adjustment instruction to adjust the headlight height, the motor controller drives the ball screw to complete the adjustment of the headlight height.

[0114] The above technical solution implements a process for automatically adjusting the headlamp height based on the driver's head state information and eye level. First, the vehicle controller obtains the driver's head state information and determines the driver's driving concentration level based on this information. Next, the vehicle controller determines whether the driver is in a focused driving state or a fatigued driving state based on the driver's driving concentration level. If the driver is in a focused driving state, the vehicle controller further obtains the driver's eye level and determines the adjusted headlamp height based on a preset correspondence to ensure optimal lighting effect. If the driver is fatigued, the driver's fatigue level is determined based on the head state information and the required headlamp lowering height is determined accordingly to further ensure optimal lighting effect. In addition, the embodiment of the present application also considers whether the adjusted headlamp height is within a safe range (i.e., between the minimum safe height and the maximum safe height). If it exceeds this safety range, the vehicle controller adjusts the headlamp height based on the minimum safe height or the maximum safe height, ensuring the rationality and safety of the headlamp adjustment and improving driving safety and comfort.

[0115] In summary, the vehicle headlight adjustment method provided by the embodiments of the present application has the following beneficial effects:

[0116] By monitoring the driver's head position in real time and dynamically adjusting the headlamp height based on this information, the driver can be provided with the most appropriate lighting in all driving situations. This intelligent adjustment mechanism not only takes into account the driver's normal driving habits, but also specifically addresses the needs of drivers experiencing fatigue. When fatigued, improper headlamp height settings, either too high or too low, can increase the driver's visual burden and risk. Therefore, the vehicle controller is being designed to automatically adjust the headlamp height based on the driver's fatigue level. When signs of driver fatigue are detected, the controller automatically lowers the headlamp height based on the driver's fatigue level. This lowering of the headlamp height aims to focus the light more closely on the nearby road, significantly improving the driver's nearby visual range. This lighting effect helps the driver more clearly see road details ahead, such as potholes, pedestrians, and non-motorized vehicles, effectively reducing blind spots. This intelligent lighting adjustment is particularly important when driving at night or in low visibility conditions, such as fog or rain. Furthermore, lowering the headlight height reduces the glare from high beams on oncoming drivers, preventing temporary blindness or blurred vision caused by excessive light, thereby reducing the risk of traffic accidents caused by improper headlight use. This design not only demonstrates concern for driver safety by providing a more comfortable and appropriate lighting environment, but also considers overall road traffic safety, providing a safe travel experience for drivers and passengers.
