Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display projection devices, and particularly relates to a display device imaging position adjusting method and a head-up display system. BACKGROUND

[0002] The head-up display system, referred to as HUD (Head Up Display), is also called a head-up display system, which is a multifunctional instrument panel centered on a driver. The head-up display system projects important driving information such as speed and navigation onto the windshield in the field of view of the driver when looking straight ahead, so that the driver can see important driving information without lowering or turning his head. The application of the head-up display system can effectively reduce the number of times the driver lowers or raises his head, so that the driver can focus on the road ahead, which is conducive to improving driving safety.

[0003] Different drivers have different heights, eye positions, driving habits, and the like, and the most suitable imaging position of the head-up display system also differs. There are mainly two methods for adjusting the imaging position height of the head-up display system in the prior art. One is a method of manually adjusting the seat position and the projection direction of the head-up display system by mechanical structure, so that the imaging position of the head-up display system is moved to the desired position of the user. The other is a method of detecting the eye position of the driver by using a sensor and image recognition technology, and automatically adjusting the imaging position of the head-up display system based on the eye position.

[0004] However, the first adjusting method is complicated to operate, and relies on the cooperation of the seat and the head-up display system to image at a suitable position. In the case of changing the driver or changing the driving habit, the seat and the head-up display system need to be adjusted again. The second adjusting method is based on the eye height of the driver, and uses a certain number of user groups to sample and calculate the median value. When the eye height is the same, the imaging position of the head-up display system is also the same, but there are individual differences between different drivers. Even if the eye height is the same, the line of sight attention area cannot be completely unified, and it is difficult to design individually for specific drivers.

[0064] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0065] Figure 1The adjusting method 100 of the imaging position of the display device according to one embodiment of the present application is shown, wherein the imaging position of the display device can be adjusted by the user, for example, the user controls the display device by the button, the wave wheel, the gear lever and the like to change the imaging position. The display device has one or more degrees of freedom of the imaging position, for example, one degree of freedom in one direction, the imaging position can be adjusted in the direction, or two degrees of freedom in two perpendicular directions, the imaging position can be adjusted in the plane defined by the two perpendicular directions, or three degrees of freedom in three perpendicular directions, the imaging position can be adjusted in the space. The display device can change the imaging position by controlling the focal length of the lens group, controlling the position of the light source, controlling the position of the display device and the like.

[0066] As Figure 1 shown, in step S101, the historical data of the user adjusting the imaging position of the display device is obtained, wherein the historical data specifically includes a plurality of imaging positions in a preset period, and the time parameter corresponding to each imaging position, and the time parameter specifically includes the duration corresponding to the imaging position. For example, the historical data includes each available imaging position of the display device, and the duration of the imaging position in the preset period is one-to-one corresponding. The preset period is a fixed time period, and the appropriate time length is set as the preset period according to the application scene of the display device, the specific needs of the user and the like, for example, 1 day, 3 days, 7 days and the like.

[0067] In step S102, the target imaging position is obtained according to the historical data, specifically, in the embodiment, the plurality of imaging positions in the historical data are screened according to the preset rule, and the target imaging position is obtained. The target imaging position is selected from the plurality of imaging positions in the historical data, specifically, the plurality of imaging positions are screened according to the time parameter corresponding to the imaging position, and the target imaging position is selected. After obtaining the target imaging position, in step S103, the display device is controlled to image in the target imaging position.

[0068] In the embodiment, the imaging position is given a time parameter, and further, the time parameter includes a duration corresponding to the imaging position. In a preset period, the duration of a certain imaging position is relatively large, indicating that the user prefers to select the imaging position when manually adjusting the imaging position, or the user prefers to maintain the imaging position when using the display device. In the screening of the target imaging position, the imaging position has a higher priority. Of course, in actual application, the time parameter can also include other calculation parameters, such as the current time, the time interval from the last shutdown, and the like, which are selected according to the specific application scenario and given different weights. In the embodiment, the target imaging position is obtained according to the user behavior and user habit, and for a specific user, the imaging position suitable for the user is output, so that the personalized setting of the imaging position is realized, the use requirement of the user is met, and the process of adjusting the imaging position of the display device is simplified.

[0069] Further, according to the preferred embodiment of the present application, in the process of obtaining the target imaging position according to the historical data, the target imaging position is obtained according to the proportion of the duration of each imaging position in the preset period. In the embodiment, the preset period is a fixed length time period, and the duration corresponding to the imaging position is also a time period or a plurality of time periods accumulated. Specifically, the use frequency and the duration of a certain imaging position in the preset period can be reflected by a ratio relationship. For example, the length of the preset period is 7 days, and the duration corresponding to the imaging position is uniform. The ratio of the duration to the preset period is calculated, and the imaging position corresponding to a larger ratio is selected as the target imaging position after comparing the ratios of a plurality of imaging positions.

[0070] In the specific embodiment of the present application, the display device is, for example, a head-up display of a vehicle, which is turned on during driving and turned off when the vehicle is parked. In the preset period, the duration corresponding to the imaging position of the display device can be discontinuous. When recording the duration corresponding to a certain imaging position in the historical data, the discontinuous duration can be superimposed to obtain the total duration of the imaging position in a preset period. Further, when the total duration is obtained by superimposition, the weight of the duration of the imaging position at the moment before the display device is turned off can be increased, and the weight of the duration of the imaging position manually adjusted by the user during use of the display device can be reduced. The duration of the imaging position at the moment before the display device is turned off indicates that the user has no intention to manually adjust the imaging position, so the weight can be appropriately increased. During use of the display device, the duration of the imaging position before manual adjustment is paused and the superimposition weight is reduced, indicating that the imaging position does not meet the use requirement of the user.

[0071] According to a preferred embodiment of the present application, the duration corresponding to each imaging position in the historical data is recorded by rounding, which can be in units of minutes, 5 minutes, 10 minutes, etc., rounding up or down, to unify the units and simplify the calculation. Preferably, the down rounding method is used. In actual application, when the duration of a certain imaging position is short, for example, a head-up display in a vehicle, the duration of a certain imaging position is only 1 minute, that is, the user manually adjusts it to other imaging positions or turns it off, or when the user manually adjusts the imaging position, the adjustment process is paused at a certain imaging position and continues, in which case the duration corresponding to the imaging position can be judged as invalid data, which is rounded down to reduce the interference of invalid data. Moreover, when a larger rounding value is selected, for example, 10 minutes, the requirement for the timing hardware is lower, which can reduce the production cost.

[0072] According to a specific embodiment of the present application, a score can be assigned to each imaging position to facilitate the calculation and comparison of the target imaging position. Specifically, the score of the imaging position can be calculated according to the following formula,

[0073] x=w2 / (w1*24*60);

[0074] y=(td / w2)*x;

[0075] wherein x represents the proportion factor of the imaging position score, y represents the score of the imaging position, w1 represents the time length of the preset period, w2 represents the rounding unit of the duration, for example, 10 minutes as the rounding unit, then w2 is 10 minutes, w1 and w2 are both preset values, which can be selected according to the application scene of the display device, 24*60 is used to unify the units of w1 and w2, and td represents the duration corresponding to the imaging position. Through the above formula, the score value of the imaging position is obtained, and the highest score value is the target imaging position.

[0076] Figure 2 The specific flow of the adjustment method 200 according to a preferred embodiment of the present application is shown. In this embodiment, the imaging position of the display device can be adjusted along the first direction, for example, the vertical direction. In different embodiments of the present application, the imaging position of the display device can be adjusted in different directions, and can be decomposed into components along three mutually perpendicular directions to simplify the calculation.

[0077] The adjustment method 200 includes the process of obtaining the second target imaging position, wherein steps S201, S202 and S203 are basically the same as steps S101, S102 and S103 in the adjustment method 100 in the foregoing embodiment, which will not be repeated here. The following will be described in combination withFigure 2 The adjustment method 200 is described.

[0078] After the display device is started, the display device directly images at the target imaging position according to the target imaging position obtained in the last preset period or in the current period. If the user adjusts the imaging position at this time, the adjustment instruction of the user is received in step S204, indicating that the current target imaging position cannot meet the use requirement of the user, wherein the adjustment instruction of the user indicates that the imaging position is adjusted on one side or the other side of the target imaging position along the first direction. For example, taking the first direction as the vertical direction, the target imaging position is located at a certain position on the vertical direction, and the adjustment instruction of the user indicates that the imaging position is located above or below the target imaging position. Specifically, the user can issue the adjustment instruction through a key, a wave wheel, a virtual key, or the like.

[0079] After receiving the adjustment instruction of the user, the second target imaging position is obtained according to the adjustment instruction of the user in the positive position set or the negative position set according to the time parameter corresponding to the imaging position in step S205. The positive position set and the negative position set are a set of imaging positions, the positive position set includes one or more imaging positions on one side of the target imaging position in the first direction, and the negative position set includes one or more imaging positions on the other side of the target imaging position in the first direction. For example, taking the first direction as the vertical direction, the target imaging position as a certain imaging position on the vertical direction, and there are other imaging positions above and / or below the target imaging position, which form the positive position set and the negative position set. The positive and negative are only used to distinguish the two sides of the target imaging position in the first direction, and do not represent the substantial positive and negative relationship.

[0080] In a specific embodiment, the display device images at the target imaging position, and after the target imaging position is determined, the positive position set and the negative position set are determined. For example, the adjustment instruction of the user indicates that the imaging position is adjusted upward, the upward adjustment corresponds to the positive position set, the second target imaging position is selected in the positive position set, and the second target imaging position is selected according to the time parameter corresponding to the imaging position. In an embodiment of the present application, for example, the second target imaging position can be selected in the positive position set according to the duration corresponding to the imaging position, or the second target imaging position can be selected according to other time parameters except the duration, such as the switching time. After the second target imaging position is obtained, the display device is controlled to image at the second target imaging position.

[0081] The adjusting method 200 in this embodiment selects a corresponding direction from the positive position set and the negative position set according to the adjusting instruction of the user, and selects a second target imaging position from the corresponding set according to the time parameter corresponding to the imaging position, when the target imaging position cannot meet the use requirement of the user. The user only needs to input an adjusting direction relative to the target imaging position (i.e. the current imaging position of the display device), and does not need to manually adjust and control the imaging position adjustment, thereby simplifying the operation process of the user. Further, after the display device images at the second target imaging position, the display device can return to step S204 to continue receiving the adjusting instruction of the user. If the user considers that the current imaging position (the second target imaging position) still cannot meet the use requirement of the user, and continues to issue the adjusting instruction, the second target imaging position can be regarded as the target imaging position, and the positive position set and the negative position set are re-divided, a new target imaging position is selected in the corresponding direction, and the cycle is repeated until the imaging position meeting the use requirement of the user is obtained. To prevent repeated adjustment between a limited number of imaging positions, further, the used imaging positions can be removed from the positive position set and the negative position set.

[0082] According to a preferred embodiment of the present application, the time parameter corresponding to the imaging position further includes a switching time point corresponding to the imaging position, and the switching time point of the imaging position represents a time point of switching to the imaging position, or a time point of switching to another imaging position at the imaging position. Specifically, when the user adjusts the imaging position, the duration of the previous imaging position is recorded, and the switching time point of the current imaging position is recorded.

[0083] In this embodiment, obtaining the second target imaging position according to the time parameter corresponding to the imaging position includes: selecting an imaging position with a switching time point closest to the current time from the positive position set or the negative position set as the second target imaging position.

[0084] This embodiment uses the switching time point corresponding to the imaging position as a condition for obtaining the second target imaging position, and the switching time point corresponding to the imaging position represents the time when the user switches the imaging position. The imaging position closest to the current time represents the imaging position most recently used by the user, which may be different from the target imaging position. In this embodiment, the display device images at the target imaging position after being turned on, but the user wants to adjust the imaging position in the first direction and inputs the adjusting instruction. After the imaging positions in the positive position set or the negative position set are screened according to the switching time point, the imaging position most recently used by the user is selected, which meets the use requirement of the user.

[0085] Further, according to the preferred embodiment of the present application, the imaging position of the display device has multiple gears, for example, after the boundary positions of the two ends of the display device are determined, the line connecting the two ends is divided into multiple segments along the first direction, and the division points are taken as gears, which can be evenly divided, that is, the distance between the imaging positions corresponding to adjacent gears is equal, or the gears with smaller intervals can be set at the middle positions, and the gears with larger intervals can be set at the positions close to the edges.

[0086] In different embodiments of the present application, the gears of the imaging position of the display device can be multiple imaging positions preset when the device is shipped, multiple imaging positions manually set by the user, or multiple imaging positions obtained by summarizing the habits of the user in setting the imaging position, or a combination of the above multiple imaging positions. Each gear corresponds to an imaging position in the first direction, and when the display device can adjust the imaging position in multiple directions, corresponding gears can be set in each adjustment direction.

[0087] According to the preferred embodiment of the present application, the imaging position gears can be set to small intervals, approximately to infinite adjustment, to provide more and finer imaging position choices for the user. In actual application, for example, when the imaging position of the display device is set to infinite adjustment, after the user manually adjusts the imaging position, if the imaging position does not correspond to the preset imaging position gears, the corresponding time parameters of the imaging position can be counted to the gear closest to the imaging position without changing the imaging position, or the imaging position can be added as a gear and the corresponding time parameters are counted separately.

[0088] Further, the historical data can be divided according to the gears of the imaging position, for example, as shown in the following table, the gears of the imaging position are numbered, and the time parameters of the imaging position corresponding to the gears, such as the duration and switching time, are recorded to form a list for easy storage and calculation. For the imaging position gears without corresponding time parameters, 0 or a temporary vacancy can be recorded. Preferably, the historical data includes the time parameters corresponding to all gears of the display device, and when the time parameters corresponding to any gear change, the list corresponding to the gears is updated.

[0089] Imaging position gear Height duration (min) Height update date 1 10 2023-3-1 9:30:10 2 60 2023-3-1 10:30:10 3 4 ...... n

[0090] In the preferred embodiment of the present application, the imaging positions of one or more gears with a non-zero corresponding duration are included in the positive position set and the negative position set within a preset period. When the display device has multiple gears, the historical data includes a time parameter corresponding to each gear, wherein the imaging positions of gears with a corresponding duration of 0 indicate that the user has not selected the imaging positions corresponding to these gears in the present preset period, and therefore in this embodiment, when the second target imaging position is obtained in the positive position set and the negative position set, the imaging positions that are not selected by the user can be removed to reduce the interference terms.

[0091] Further, the standard imaging position is not included in the positive position set and / or the negative position set, the standard imaging position is a preset imaging position of the display device, for example, the imaging position set at the factory, when the display device is first turned on, the display device images at the standard imaging position, after the user adjusts the imaging position of the display device, the historical data corresponding to the imaging position is generated, and the target imaging position is obtained according to the aforementioned adjustment method, in this case, it is considered that the standard imaging position cannot meet the user's use requirements, and therefore the standard imaging position can be removed from the positive position set and / or the negative position set to further reduce the interference terms.

[0092] In actual application, when the positive position set or the negative position set corresponding to the adjustment direction of the user's adjustment instruction is an empty set, the imaging position of the gear closest to the target imaging position is selected as the second target imaging position. For example, on the side of the target imaging position in the first direction, for example, the positive position set has imaging position gears, but the corresponding duration of one or more gears in the positive position set is 0, according to the foregoing embodiment, this part of the imaging position is removed from the set, therefore, the positive position set and the negative position set may have an empty set, in this case, if the received user adjustment instruction corresponds to an empty set in the position set in the adjustment direction. For example, the first direction is the vertical direction, the user's adjustment instruction indicates to adjust the imaging position upward, but in a preset period, the user has not used the imaging positions above the target imaging position, i.e., the positive position set is an empty set, in this embodiment, the gear closest to the target imaging position and in the same direction as the direction indicated by the adjustment instruction is selected as the second target imaging position.

[0093] In a preferred embodiment of the present application, the preset periods are continuous, when a preset period ends, the next preset period starts, in this embodiment, the historical data of the previous preset period, including the imaging position or the time parameter corresponding to the imaging position level, is cleared, and the target imaging position obtained from the historical data of the previous preset period is retained. When the display device is started next time, imaging is performed at the target imaging position, and the historical data of the present preset period is recorded again. When a preset period ends and the display device is in working state, the historical data of the previous preset period is cleared, and the current imaging position is not changed whether the current imaging position is the same as the target imaging position of the previous preset period or not.

[0094] Specifically, the target imaging position can change over time in a preset period, in this embodiment, the target imaging position is obtained according to the historical data each time the display device is started, and imaging is performed at the target imaging position. Since the preset periods in this embodiment are continuous, when a preset period ends and the next preset period starts, the historical data is cleared, in order to ensure that the display device has the imaging position meeting the user's demand when it is started next time, the target imaging position obtained from the historical data of the previous preset period is retained. Further, according to the preferred embodiment of the present application, when the target imaging position is clear, a second target imaging position can be obtained in the positive position set and the negative position set, and the second target imaging position is retained, and imaging can be performed at the second target imaging position after receiving the user's adjustment instruction. Specifically, a second target imaging position can be determined in the positive position set and the negative position set respectively, and the second target imaging position is selected according to the direction indicated by the user's adjustment instruction.

[0095] During the use of the display device, the duration corresponding to the imaging position is accumulated, and when the user uses the display device for a long time, the duration corresponding to the frequently used imaging position is much longer than the duration corresponding to other imaging positions. In this case, if the user's usage habit changes or the user's required imaging position changes, and the duration corresponding to the adjusted imaging position is much shorter than the duration corresponding to the previously frequently used imaging position, when the display device is started next time, the imaging position is still the previously frequently used imaging position, and the user's required imaging position cannot be quickly adjusted. To solve this defect, the historical data is cleared in units of preset periods in this embodiment, so as to avoid excessive accumulation of the duration corresponding to the imaging position, and to avoid the failure to timely adapt to the change of the user's behavior habit and usage demand.

[0096] Figure 3The specific flow of the adjusting method 300 according to one preferred embodiment of the present application is shown, which specifically includes the process of clearing the historical data after a preset period and the process of judging whether there is historical data. In the adjusting method 300, the steps S303, S304 and S305 are basically the same as the steps S101, S102 and S103 in the adjusting method 100 in the foregoing embodiment respectively, and thus will not be described again.

[0097] In the step S301, it is judged whether there is historical data. When there is historical data, the following step S303 is continued, and the display device is controlled to image at the target imaging position. When there is no historical data, the display device is controlled to image at a standard imaging position in the step S302, wherein the standard imaging position is a preset imaging position, for example, an imaging position set by the display device when it is manufactured, and can be an average value suitable for some users obtained by collecting information of a plurality of users.

[0098] The case where there is no historical data includes the case where the display device is used for the first time. When there is no user individual setting information, the display device is controlled to image at the standard imaging position, and the target imaging position can be obtained according to the historical data in the following use. The case where there is no historical data also includes the case where the historical data in the last preset period is cleared after the preset period ends. At this time, the display device can be controlled to image at the target imaging position as in the foregoing embodiment, or can be controlled to image at the standard imaging position and record the historical data again to obtain the target imaging position.

[0099] According to a preferred embodiment of the present application, it further comprises: receiving a preset instruction of the user, and clearing the historical data and the target imaging position. In a specific application, the preset instruction of the user is, for example, a specific key or a specific combination of keys, and the like. After receiving the preset instruction of the user, the historical data and the target imaging position are cleared, and the display device is restored to the initial state. According to the foregoing embodiment, the duration of the imaging position is accumulated. By setting a suitable length of the preset period, the duration accumulated by a certain imaging position from affecting the subsequent imaging position to become the target imaging position can be avoided. After the preset period ends, the duration of the imaging position is recorded again. The present embodiment provides another method for overcoming the accumulation of the duration of the imaging position. The preset instruction of the user is set in advance. After receiving the preset instruction of the user, the historical data and the target imaging position are cleared, and the use habit of the user is recorded again. Specifically, for example, the user continuously uses a first imaging position for a period of time, manually adjusts to a second imaging position, and starts to continuously use the second imaging position. However, because the duration accumulated by the first imaging position is greater than that of the second imaging position, the default imaging position is still the first imaging position with a longer duration when the display device is started next time. In this case, the historical data can be cleared and the target imaging position (i.e., the first imaging position) can be cleared according to the preset instruction of the user before the preset period ends. The user uses the second imaging position, and the time parameter of the imaging position is recorded again. The influence of the duration of the first imaging position is cleared, the duration accumulated by the second imaging position is ensured to be greater, and the second imaging position becomes the target imaging position. When the display device is started next time, the imaging position is the second imaging position.

[0100] As shown in FIG. 1, Figure 4 The present application also includes an embodiment of a head-up display system 1, wherein the head-up display system 1 comprises an optical-mechanical module 10, a driving module 20, a human-computer interaction module 30, a self-learning module 40, and a control module 50.

[0101] The optical-mechanical module 10 is capable of projecting images at multiple imaging positions. Specifically, the optical-mechanical module 10 comprises, for example, a light source and a lens group, and is capable of projecting images to a target position under control. The driving module 20 is used to adjust the imaging position of the optical-mechanical module 10, for example, by adjusting the optical power of the lens group, changing the position of the optical-mechanical module 10, and the like, so as to change the imaging position of the optical-mechanical module 10. The driving module 20 can be a controlled motor and a transmission assembly matched with the motor. The human-computer interaction module 30 is capable of receiving user adjustment instructions. It can be a touch operation interface with virtual keys, or a physical key, a wave wheel, a push rod, and the like. According to the specific behavior of the user, the user adjustment instructions are received.

[0102] The self-learning module 40 is configured to obtain historical data of the user adjusting the imaging position, wherein the historical data comprises a plurality of imaging positions in a preset period and a time parameter corresponding to each imaging position, and the time parameter comprises a duration corresponding to the imaging position. The self-learning module 40 obtains the target imaging position according to the historical data, specifically comprising: filtering the plurality of imaging positions in the historical data according to a preset rule to obtain the target imaging position, for example, the self-learning module 40 executes the adjusting method in the foregoing embodiment.

[0103] As shown in Figure 4 The control module 50 is in communication with the human-computer interaction module 30 and the self-learning module 40, and is configured to control the driving module 20 according to the user adjustment instruction and the target imaging position obtained by the self-learning module 40, so that the optical-mechanical module 10 can image at the corresponding imaging position. For example, the user inputs a specific imaging position through the human-computer interaction module 30, and the control module 50 controls the driving module 20 to make the optical-mechanical module 10 image at the position.

[0104] According to a preferred embodiment of the present application, the head-up display system 1 further comprises a user data storage module 60, wherein the user data storage module 60 is in communication with the human-computer interaction module 30 and the self-learning module 40, and in different embodiments of the present application, the user data storage module 60 can also be configured to communicate with the control module 50, or simultaneously communicate with the human-computer interaction module 30, the self-learning module 40 and the control module 50. The user data storage module 60 is used to record and store the imaging position and the corresponding time parameter, can obtain the time parameter corresponding to the imaging position from the human-computer interaction module 30 and / or the control module 50, and can provide the historical data to the self-learning module 40 or through the control module 50 to the self-learning module 40, so that the self-learning module 40 obtains the target imaging position. Specifically, the user data storage module 60 is, for example, a readable and writable memory.

[0105] According to a specific embodiment of the present application, wherein the self-learning module 40 can be configured to obtain the target imaging position according to the proportion of the duration of each imaging position in the preset period, specifically for example, calculating the score of each imaging position according to the calculation formula shown in the adjusting method in the foregoing embodiment, and selecting the highest score as the target imaging position. Further, wherein the duration corresponding to each imaging position can be recorded by rounding, and rounding the duration of the imaging position can be calculated according to the rounding rule in the user data storage module 60, or the duration of the imaging position can be counted according to the set rounding unit when writing into the user data storage module 60.

[0106] In a preferred embodiment of the present application, the imaging position of the optical-mechanical module 10 can be adjusted along a first direction, for example, a vertical direction, or along the slope direction of the front windshield of the vehicle on which the head-up display system 1 is located.

[0107] The self-learning module 40 is configured to, when the user adjustment instruction indicates adjusting the imaging position to one side or the other side of the target imaging position along the first direction, obtain a second target imaging position according to the time parameter corresponding to the imaging position in the positive position set or the negative position set according to the user adjustment instruction. Correspondingly, the control module 50 is configured to control the optical engine module 10 to image at the second target imaging position.

[0108] The positive position set includes one or more imaging positions on one side of the target imaging position along the first direction. The negative position set includes one or more imaging positions on the other side of the target imaging position along the first direction. Specifically, when the user adjustment instruction adjusts the imaging position upward or downward, the self-learning module 40 is used to obtain the second target imaging position in the corresponding direction, and the optical engine module 10 is controlled by the control module 50 and the driving module 20 to image at the second target imaging position. The specific steps are, for example, the adjustment method in the foregoing embodiment, which simplifies the user operation, for example, the user only needs to input the direction relative to the target imaging position through the human-computer interaction module 30, and the optical engine module 10 is controlled by the control module 50 to image at the second target imaging position.

[0109] In the process of obtaining the second target imaging position, the time parameter further includes a switching time corresponding to the imaging position. The self-learning module 40 is configured to select, in the positive position set or the negative position set, the imaging position closest to the current time as the second target imaging position. According to a preferred embodiment of the present application, the imaging position of the optical engine module 10 has multiple gears, and the positive position set and the negative position set include the imaging positions of one or more gears with a non-zero duration in a preset period, so as to remove the imaging positions that are not selected by the user in one preset period. Further, in a preferred embodiment of the present application, when the positive position set or the negative position set corresponding to the adjustment direction of the user adjustment instruction is an empty set, the imaging position of the gear closest to the target imaging position is selected as the second target imaging position.

[0110] According to a preferred embodiment of the present application, the positive position set and / or the negative position set can also be configured to not include the standard imaging position. In this embodiment, the standard imaging position is the imaging position preset by the head-up display system 1, for example, the imaging position information collected by the user and selected, and the standard imaging position suitable for part of the users is obtained. After being manually adjusted by the user, the standard imaging position is excluded from the positive position set and the negative position set to eliminate the interference of the standard imaging position. In combination with the foregoing embodiment, part of the imaging positions with lower selection willingness of the users are removed in the positive position set and the negative position set, so that the obtained second target imaging position is more likely to meet the use requirements of the users.

[0111] Specifically, in the preferred embodiment of the present application, when the user adjusts the imaging position, for example, the user can adjust the direction of the imaging position relative to the target imaging position, which can also be manually adjusted, so that the optical engine module 10 images at the appropriate position or gear, after the adjustment is completed, the user data storage module 60 records the duration of the previous imaging position, and records the switching time of the current imaging position, which can be recorded by the user adjustment instruction received by the human-computer interaction module 30, in combination with a device with a timing function, to record the time parameter of the imaging position, which can be shown in the form of the table as described in the foregoing embodiment, and each imaging position or gear is numbered and its corresponding time parameter is recorded. For the imaging position without corresponding time parameter, the duration can be recorded as 0, and the switching time can be blank.

[0112] According to the preferred embodiment of the present application, the user data storage module 60 is further configured to clear the historical data of the previous preset period, including the time parameter corresponding to the imaging position, after a preset period, and retain the target imaging position. At the end of a preset period, the target imaging position is obtained according to the time parameter corresponding to the imaging position in the preset period, and at the next start of the head-up display system 1, the optical engine module 10 can image at the target imaging position and record the time parameter corresponding to the imaging position again to form the historical data of the present preset period. In this embodiment, the historical data is cleared to reduce the influence of the duration accumulation, avoid the influence of the previously used imaging position on the subsequently selected imaging position as the target imaging position, and eliminate the influence of the misoperation to some extent.

[0113] In other embodiments of the present application, the control module 50 can also be configured to control the optical engine module 10 to image at a preset standard imaging position when there is no historical data, wherein the preset standard imaging position can be the imaging position set by the head-up display system 1 at the factory, and the user keeps using the imaging position or adjusts the imaging position, then the historical data of the imaging position is recorded, and the target imaging position is obtained by the self-learning module 40 according to the historical data and through the foregoing adjustment method, to meet the individualized settings and needs of the user.

[0114] According to one preferred embodiment of the present application, specifically further comprising: the human-computer interaction module 30 is configured to receive the preset instruction of the user, for example, the user triggers the reset button, long-presses a specific button or button combination, etc., after receiving the preset instruction of the user, the user data storage module 60 clears the historical data and the target imaging position according to the preset instruction of the user, and records the time parameter corresponding to the imaging position again.

[0115] The embodiment can overcome the problem of imaging position duration accumulation, causing the subsequent imaging position to become a target imaging position, clear the historical data and the target imaging position in the user data storage module 60 after receiving the preset instruction of the user, and record the use habits of the user again.

[0116] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be recorded in the technical scheme of the foregoing each embodiment is modified, or part of the technical features are replaced.
