For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0029] Drivers cannot accurately and quickly adjust the angles of the side mirrors of the vehicle to a satisfactory level using existing electronic control buttons. Therefore, one aspect of this application provides a method for adjusting vehicle side mirrors. Please refer to the details below. Figure 1 , Figure 1 This is a schematic flowchart illustrating a method for adjusting a vehicle rearview mirror according to an exemplary embodiment of this application. The adjustment method includes at least steps S110 to S140, which are described in detail below:

[0030] S110: Obtain the driver's eye position, the first intersection point of the line connecting the eye position to the target, and the second intersection point of the driver's body position with the target horizontal plane; wherein, the target line is the line connecting the first rearview mirror and the second rearview mirror, and the target horizontal plane is the horizontal plane where the first rearview mirror and the second rearview mirror are located.

[0031] Eye position refers to the position of the driver's eyes when the driver has adjusted their driving posture; body position refers to the position of the driver's upper body directly in front of the steering wheel while sitting in the driver's seat.

[0032] The target line is the line connecting the center points of the first and second rearview mirrors, which is parallel to the horizontal plane of the vehicle and contained within the target horizontal plane. The target horizontal plane is parallel to the horizontal plane of the vehicle body and is parallel to the ground. The first rearview mirror is the driver's side mirror, and the second rearview mirror is the passenger side mirror.

[0033] For example, please refer to Figure 2 , Figure 2 This is a schematic diagram of specific points inside a vehicle as shown in an exemplary embodiment of this application. Point o is the first intersection point, point d is the second intersection point, point p is the driver's eye position, point a is the position of the first rearview mirror, and point b is the position of the second rearview mirror; the plane containing points a, d, and o is the target horizontal plane; and line segment ab is the target connecting line.

[0034] S120: Based on the eye position and the first rearview mirror, determine the target angle between the target line segment from the eye position to the first rearview mirror and the target horizontal plane.

[0035] For example, such as Figure 2 As shown, the target line segment from the eye position to the first rearview mirror is pa, the target horizontal plane is the plane where points a, d, and o are located, and the angle between the target line segment and the target horizontal plane is α, which is the target angle in this embodiment. In triangle pda, α can be quickly calculated using the corresponding trigonometric function relationships.

[0036] S130: Determine the first distance value based on the second intersection point and the first intersection point, and determine the second distance value based on the eye position and the second intersection point.

[0037] For example, such as Figure 2 As shown, the first distance value is the length value corresponding to line segment do, and the second distance value is the length value corresponding to line segment pd.

[0038] S140: Based on the target angle, the first distance value and the second distance value, determine the target preset adjustment strategy to adjust the angle of the first rearview mirror and the second rearview mirror.

[0039] There is a corresponding relationship between the preset adjustment strategy and the preset parameter group. The preset parameter group includes the preset included angle, the preset first distance value and the preset second distance value.

[0040] For example, the target angle, first distance value, and second distance value calculated in the above steps are matched with the corresponding preset parameters in the preset parameter group to calculate the matching degree of the preset parameter group corresponding to each preset adjustment strategy. The preset adjustment strategy with the highest matching degree is taken as the target preset adjustment strategy. The preset parameter group originates from a calibration library based on real-vehicle testing. The calibration library records the body measurements of different drivers and the corresponding preset adjustment angles of the first and second rearview mirrors. In subsequent embodiments, the absolute value and weighted value of the difference are related to the body measurements in the calibration library. Simultaneously, the driver's preference can be used to manually adjust the rearview mirror angle, which is then recorded in the calibration library and updated as a new preset parameter group. Different drivers may have different heights, arm spans, and sitting postures, and their eye positions and body positions may also differ. This embodiment only needs to determine three specific points: the driver's eye position, the first intersection point between the eye position and the first and second rearview mirrors, and the second intersection point between the driver's body position and the horizontal plane where the first and second rearview mirrors are located. This allows for the rapid determination of the target angle between the target line segment from the driver's eye position to the first rearview mirror and the horizontal plane where the two rearview mirrors are located, the first distance value between the first and second intersection points, and the second distance value between the eye position and the second intersection point. Based on the target angle, the first distance value, and the second distance value, a target preset adjustment strategy is determined to adjust the angles of the first and second rearview mirrors, thereby automatically and quickly adjusting the rearview mirror angles to a suitable angle for the current driver.

[0041] In another exemplary embodiment of this application, it is described in detail how to determine a target preset adjustment strategy based on the target angle, a first distance value, and a second distance value. Please refer to [link to relevant documentation] for details. Figure 3 , Figure 3 Based on Figure 1 The exemplary embodiment shown illustrates a flowchart of another method for adjusting a vehicle rearview mirror.

[0042] Each preset adjustment strategy corresponds to a preset included angle, a preset first distance value, and a preset second distance value; this adjustment method is used in situations such as... Figure 1 The S140 shown further includes S310 to S320, which are described in detail below:

[0043] S310: Calculate the first weighted value, second weighted value, and third weighted value corresponding to each preset adjustment strategy by comparing the target angle, first distance value, and second distance value with the preset angle, preset first distance value, and preset second distance value corresponding to each preset adjustment strategy.

[0044] S320: Determine the target preset adjustment strategy based on the first weighted value, the second weighted value, and the third weighted value corresponding to each preset adjustment strategy.

[0045] For example, the difference between the target angle and the preset angle, the first distance value and the preset first distance value, and the second distance value and the preset second distance value are calculated respectively, and the first weighted value, the second weighted value, and the third weighted value corresponding to the three differences are determined respectively; the three weighted values ​​are summed to obtain the weighted sum value corresponding to multiple preset adjustment strategies, and the preset adjustment strategy corresponding to the smallest weighted sum value is taken as the target preset adjustment strategy.

[0046] In some embodiments, if there are multiple minimum weighted sum values, the preset adjustment strategy with the preset angle closer to the target angle is selected as the target preset adjustment strategy. For example, if the target angle is 10°, the weighted sum values ​​corresponding to the first preset adjustment strategy and the second preset adjustment strategy are both minimum values; wherein, the preset angle corresponding to the first preset adjustment strategy is 8°, and the preset angle corresponding to the second preset adjustment strategy is 10°, that is, the preset angle corresponding to the second preset adjustment strategy is closer to the target angle, then the second preset adjustment strategy is selected as the target preset adjustment strategy.

[0047] This embodiment provides a method for determining a target preset adjustment strategy by calculating the target angle, the first distance value, the second distance value, the corresponding first weighted value, the second weighted value, and the third weighted value, and quickly determining the target preset adjustment strategy based on the three weighted values.

[0048] In another exemplary embodiment of this application, it is described in detail how to determine the target preset adjustment strategy based on the first weighted value, the second weighted value, and the third weighted value corresponding to each adjustment strategy, that is, the above-mentioned S320 further includes S3201 to S3202, which are described in detail below:

[0049] S3201: Iterate through multiple preset adjustment strategies, and sum the first weighted value, second weighted value and third weighted value corresponding to the preset adjustment strategy to obtain the weighted sum value corresponding to the preset adjustment strategy, so as to obtain the weighted sum value corresponding to each preset adjustment strategy.

[0050] This embodiment ensures that the preset parameter group corresponding to each preset adjustment strategy is calculated without omission by traversing each preset adjustment strategy, so as to obtain the three weighted values ​​and the weighted sum value corresponding to each preset adjustment strategy.

[0051] S3202: Use the preset adjustment strategy corresponding to the smallest weighted sum among multiple weighted sums as the target preset adjustment strategy.

[0052] For example, if the weighted sum value corresponding to the first preset adjustment strategy is 5, the weighted sum value corresponding to the second preset adjustment strategy is 6, and the weighted sum value corresponding to the third preset adjustment strategy is 7, then the minimum weighted sum value is 5, and the first preset adjustment strategy is taken as the target preset adjustment strategy.

[0053] In another exemplary embodiment of this application, it is described in detail how to calculate the first weighted value, the second weighted value, and the third weighted value corresponding to each adjustment strategy by comparing the target angle, the first distance value, and the second distance value with the preset angle, the preset first distance value, and the preset second distance value corresponding to each preset adjustment strategy. Please refer to [link to relevant documentation] for details. Figure 4 , Figure 4 Based on Figure 3 The illustrated exemplary embodiment presents a flowchart of another method for adjusting a vehicle rearview mirror. This adjustment method, as shown in the example... Figure 3 The S310 shown further includes S410 to S430, which are described in detail below:

[0054] S410: Determine the first weighted value corresponding to each preset adjustment strategy based on the absolute value of the difference between the target angle and the corresponding preset angle in each preset adjustment strategy.

[0055] For example, if the target angle is 80° and the preset angle corresponding to the first preset adjustment strategy is 70°, then the absolute value of the difference = |80°-70°| = 10°, and the first weighted value corresponding to the first preset adjustment strategy is determined based on the absolute value of the difference.

[0056] S420: Determine the second weighted value corresponding to each preset adjustment strategy based on the absolute value of the difference between the first distance value and the corresponding preset first distance value in each preset adjustment strategy.

[0057] Similarly, the absolute value of the difference between the first distance value and the preset first distance value corresponds to a corresponding second weighting value, and the corresponding weighting value can be quickly determined based on the absolute value of the difference.

[0058] S430: Determine the third weighted value corresponding to each preset adjustment strategy based on the absolute value of the difference between the second distance value and the corresponding preset second distance value in each preset adjustment strategy.

[0059] The specific values ​​of the first weighted value, the second weighted value, and the third weighted value may be the same or different. This application does not limit the size relationship between them or their specific values.

[0060] This embodiment specifically illustrates how to determine the three weighted values ​​corresponding to each preset adjustment strategy. The first weighted value, the second weighted value, and the third weighted value are quickly determined based on the absolute value of the difference between the target angle and the preset angle, the absolute difference between the first distance value and the preset first distance value, and the absolute difference between the second distance value and the preset second distance value.

[0061] In another exemplary embodiment of this application, it is described in detail how to determine the first weighted value corresponding to each preset adjustment strategy based on the absolute value of the difference between the target angle and the preset angle corresponding to each preset adjustment strategy, that is, the above-mentioned S410 further includes S4101 to S4102, which are described in detail below:

[0062] S4101: Match the absolute value of the difference between the target angle and the corresponding preset angle in each preset adjustment strategy with a preset value range to determine the preset value range that is successfully matched.

[0063] S4102: Use the preset weighted value corresponding to the successfully matched preset value range as the first weighted value corresponding to the corresponding preset adjustment strategy to determine the first weighted value corresponding to each preset adjustment strategy.

[0064] This embodiment is illustrated by way of example. The first weighting value corresponding to each preset adjustment strategy is determined according to Table 1. Table 1 is a table showing the correspondence between the absolute value of the difference and the weighting value.

[0065]

[0066] Table 1

[0067] Each preset adjustment strategy corresponds to a preset angle. For example, the preset angle corresponding to the first preset adjustment strategy is α1 in Table 1, and the preset angle corresponding to the second preset adjustment strategy is α2 in Table 1.

[0068] Similarly, the second weighted value corresponding to each preset adjustment strategy is determined by example according to Table 2, and the second weighted value corresponding to each preset adjustment strategy is determined according to Table 3; wherein, Table 2 is a correspondence table between the first distance value and the weighted value, and Table 3 is a correspondence table between the second distance value and the weighted value.

[0069]

[0070] Table 2

[0071]

[0072] Table 3

[0073] This embodiment further illustrates the specific process of determining the first weighted value corresponding to each preset adjustment strategy. By matching the absolute value of the difference between the target angle and the preset angle corresponding to each preset adjustment strategy with a preset numerical range, the corresponding weighted value can be determined quickly and accurately.

[0074] Each preset adjustment strategy includes a preset parameter group, as shown in Table 4. Table 4 is an example table of preset parameters in the preset adjustment strategy. The target preset adjustment strategy is determined from multiple preset adjustment strategies. The target preset adjustment strategy corresponds to the horizontal and numerical adjustment angles of the first and second rearview mirrors.

[0075]

[0076] Table 4

[0077] In some embodiments, relevant parameters after the user manually adjusts the rearview mirror, namely the adjusted target angle, the first distance value, and the second distance value, can also be recorded and entered into a calibration library as a new preset adjustment strategy. This updates the calibration library containing the preset adjustment strategies, facilitating the rapid matching of a suitable target preset adjustment strategy for the driver. The parameters after the user manually adjusts the rearview mirror have higher priority than the preset parameters before the vehicle leaves the factory.

[0078] In another exemplary embodiment of this application, it is described in detail how to determine the target angle between the target line segment from the eye position to the first rearview mirror and the target horizontal plane based on the eye position and the first rearview mirror. That is, S120 in any of the above exemplary embodiments further includes S1201 to S1203, which are described in detail below:

[0079] S1201: Determine the distance from the eye position to the second intersection point based on the eye position and the second intersection point.

[0080] For example, the three-dimensional coordinates of the eye position are (x1, y1, z1), and the three-dimensional coordinates of the second intersection point are (x1, y1, z1). The distance from the eye position to the second intersection point is calculated using the following formula:

[0081]

[0082] Where d is the distance from the eye position to the second intersection point.

[0083] Another example, such as Figure 2 As shown, in triangle aod, ∠aod = 90°. Using the Pythagorean theorem, the distance from the eye position to the second intersection point can be calculated (i.e.,...). Figure 2 The length of the median segment 'ad' is calculated using the following formula:

[0084]

[0085] Where ao is the distance between the center point of the first rearview mirror and the first intersection point. This parameter does not change with different drivers, that is, ao is a constant parameter throughout the adjustment process; do is the distance between the second intersection point and the first intersection point, which is a variable parameter.

[0086] S1202: Determine the distance from the first rearview mirror to the second intersection point based on the first rearview mirror and the second intersection point.

[0087] Similarly, the distance from the center point of the first rearview mirror to the second intersection point can be calculated based on the corresponding three-dimensional coordinates.

[0088] S1203: Based on the distance from the eye position to the second intersection point and the distance from the eye position to the second intersection point, calculate the target angle between the target line segment from the eye position to the first rearview mirror and the target horizontal plane.

[0089] For example, such as Figure 2 As shown, the distance from the eye position to the second intersection point is the length of line segment pd, and the distance from the center of the first rearview mirror to the second intersection point is the length of line segment ad. Since ∠pda = 90° in triangle dpa, α = arctan(pd / ad). Furthermore, the value of ad can also be calculated in triangle aod using the Pythagorean theorem, since ∠aod = 90°. but

[0090] This embodiment uses simple trigonometric relationships and the Pythagorean theorem to conveniently and quickly calculate the target angle between the target line segment from the eye position to the first rearview mirror and the target horizontal plane.

[0091] In another exemplary embodiment of this application, the pre-steps of the adjustment method in any of the above embodiments are described in detail. That is, the adjustment method shown in any of the above exemplary embodiments further includes S11 to S12, which are described in detail below:

[0092] S11: Detect whether a command to adjust the rearview mirror angle has been received, and detect whether the current vehicle speed is zero.

[0093] The command to adjust the rearview mirror angle is triggered by the driver. For example, the driver can trigger the command via a physical button inside the vehicle, or by issuing a voice command such as "adjust the rearview mirror angle." The following provides an example scenario for voice interaction commands:

[0094] When the driver enters the driver's seat, the execution segment control voice module in this embodiment plays the question, "Excuse me, do you need to adjust the rearview mirror angle?" If the driver replies with an affirmative voice such as "Okay" or "Sure," a command to adjust the rearview mirror angle is triggered. In certain non-driving scenarios, the user can proactively trigger the adjustment command to adjust the rearview mirror angle in a timely manner.

[0095] S12: If all are yes, then execute the steps of obtaining the driver's eye position, the first intersection of the line connecting the eye position to the target, and the second intersection of the driver's body position with the target horizontal plane.

[0096] The rearview mirror adjustment process begins only when the vehicle is in a non-driving state, i.e., the vehicle speed is zero, and the main body detects and receives the instruction to adjust the rearview mirror angle. Then, the above-mentioned S110 is executed to effectively prevent the rearview mirror angle adjustment instruction from being accidentally triggered during driving, which would cause the rearview mirror angle to change during driving and interfere with the driver's normal driving, thereby improving vehicle driving safety to a certain extent.

[0097] In another exemplary embodiment of this application, the application scenarios of the above-mentioned adjustment methods are illustrated by way of example. Please refer to the following for details. Figure 5 , Figure 5 This is a schematic diagram illustrating an application scenario of the vehicle rearview mirror adjustment method of this application. It includes a vehicle 100 and a server 200, which can be connected wirelessly. This application does not limit the connection method between them. The server 200 can be as follows... Figure 5 The device shown can be placed inside or outside the vehicle 100; this application does not limit its placement.

[0098] Server 200, acting as the execution entity, can execute the adjustment method shown in any of the exemplary embodiments described above, as illustrated below:

[0099] Server 200 acquires the driver's eye position, the first intersection point of the line connecting the eye position to the target, and the second intersection point of the driver's body position with the target horizontal plane; wherein, the target line is the line connecting the first rearview mirror and the second rearview mirror, and the target horizontal plane is the horizontal plane where the first rearview mirror and the second rearview mirror are located; Server 200 determines the target angle between the target line segment from the eye position to the first rearview mirror and the target horizontal plane based on the eye position and the first rearview mirror; Server 200 determines a first distance value based on the second intersection point and the first intersection point, and determines a second distance value based on the eye position and the second intersection point; Server 200 determines a target preset adjustment strategy based on the target angle, the first distance value and the second distance value to adjust the angles of the first rearview mirror and the second rearview mirror.

[0100] Server 200 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. Multiple servers can form a blockchain, and the server is a node on the blockchain. Server 200 can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.
