[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0032] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0033] like Figure 1 As shown, an embodiment of the present application provides a steering wheel adjustment method, the method comprising:

[0034] Step 101, obtaining the driver's sight channel for observing the instrument screen and the current position of the steering wheel.

[0035] The visual channel here is the visual channel corresponding to the driver's eyes observing the instrument screen when the driver sits in the driving position and looks forward. The visual channel is a three-dimensional spatial structure. Specifically, the driver's eye position can be captured by an image acquisition device, and then the driver's visual channel for observing the instrument screen can be determined based on the obtained driver's eye position and the position of the instrument screen.

[0036] Specifically, the current position of the steering wheel can be obtained by a steering wheel sensor installed on the steering column of the steering wheel.

[0037] Step 102: Determine whether the steering wheel blocks the visual channel according to the visual channel and the current position of the steering wheel.

[0038] Since the driver mainly views the information provided on the instrument screen through the hollow portion between the wheel hub and the rim on the steering wheel while driving the vehicle, when the driver's line of sight channel for observing the instrument screen and the current position of the steering wheel are obtained, it can be determined whether the steering wheel blocks the line of sight channel, that is, whether the wheel hub and the rim of the steering wheel block the line of sight channel based on the line of sight channel and the current position of the steering wheel. Only when the steering wheel does not block the line of sight channel can the driver fully view the information provided on the instrument screen through the hollow portion between the wheel hub and the rim on the steering wheel. When the steering wheel blocks the line of sight channel, the driver cannot fully view all the information provided on the instrument screen through the hollow portion between the wheel hub and the rim on the steering wheel. At this time, if the driver needs to view the information on the instrument screen blocked by the wheel hub and / or rim on the steering wheel, he needs to move his body or head.

[0039] Step 103, when the steering wheel blocks the visual channel, determine a steering wheel target position according to the visual channel and the current position of the steering wheel. When the steering wheel is at the steering wheel target position, the steering wheel does not block the visual channel.

[0040] When it is determined that the steering wheel blocks the line of sight, it means that when the steering wheel is in the current position, it will block the driver's line of sight from observing the instrument screen. At this time, the position of the steering wheel can be adjusted so that it does not block the driver's line of sight from observing the instrument screen. Therefore, it is necessary to determine a steering wheel target position. When the steering wheel is at the steering wheel target position, the steering wheel will not block the driver's line of sight from observing the instrument screen.

[0041] Step 104: adjust the steering wheel from the current steering wheel position to the target steering wheel position.

[0042] After determining the target position of the steering wheel, the steering wheel is adjusted from the current position of the steering wheel to the target position of the steering wheel so that the steering wheel does not block the driver's visual channel for observing the instrument screen.

[0043] In the embodiment of the present application, by obtaining the sight line channel for the driver to observe the instrument screen and the current position of the steering wheel, and when the steering wheel blocks the sight line channel, determining the steering wheel target position corresponding to the steering wheel not blocking the sight line channel, and adjusting the position of the steering wheel to the steering wheel target position, the position of the steering wheel can be automatically adjusted when the steering wheel blocks the instrument screen for the driver to observe, so that the steering wheel does not block the instrument screen for the driver to observe, thereby improving the intelligence of the vehicle cockpit and the user experience.

[0044] In an optional embodiment of the present application, obtaining a sight line channel for a driver to observe an instrument screen includes:

[0045] Acquire a first position corresponding to the left eye and a second position corresponding to the right eye of the driver;

[0046] The space formed by the lines connecting the first position and the two vertices on the right side of the instrument screen and the space formed by the lines connecting the second position and the two vertices on the left side of the instrument screen is determined as the visual channel.

[0047] Specifically, the first position corresponding to the left eye and the second position corresponding to the right eye of the driver can be obtained by an image acquisition device, such as Figure 2 As shown, the first position 211 is connected to the two vertices on the right side of the instrument screen 220 to obtain two visual lines, and the second position 212 is connected to the two vertices on the left side of the instrument screen 220 to obtain two visual lines, and then the space formed by the four visual lines is determined as the visual channel 200.

[0048] In the above implementation scheme of the present application, the space formed by the lines connecting the first position corresponding to the left eye and the two vertices on the right side of the instrument screen and the lines connecting the second position corresponding to the right eye and the two vertices on the left side of the instrument screen are determined as the visual channel, so that it can be determined based on the visual channel whether the steering wheel blocks the driver's view of the instrument screen.

[0049] In an optional embodiment of the present application, obtaining a first position corresponding to the left eye and a second position corresponding to the right eye of the driver includes:

[0050] Acquire the driver's facial image through an image acquisition device;

[0051] The left eye and the right eye in the facial image are identified to obtain the first position and the second position.

[0052] Specifically, Figure 3As shown, the image acquisition device includes an infrared camera respectively arranged on the upper and lower edges of the instrument screen, which are a first camera 301 and a second camera 302, wherein the first camera 301 and the second camera 302 form a compensation angle θ through the steering wheel rim 303 and the wheel hub 304 to cover the entire face of the driver, and the facial image of the driver is obtained through the first camera 301 and the second camera 302, and then the left eye and the right eye in the collected facial image are identified, so as to obtain a first position corresponding to the left eye and a second position corresponding to the right eye.

[0053] The above-mentioned implementation scheme of the present application obtains the first position and the second position by identifying the eyes on the acquired facial image of the driver, thereby making it possible to locate the position of the driver's eyes more accurately.

[0054] In an optional embodiment of the present application, judging whether the steering wheel blocks the visual channel according to the visual channel and the current position of the steering wheel includes:

[0055] Acquire a hollow area of ​​the uppermost hollow portion between the rim and the hub of the steering wheel on the plane where the rim of the steering wheel is located when the steering wheel is in the return position;

[0056] Acquire a section area of ​​the sight channel on the plane where the rim of the steering wheel is located;

[0057] When the hollow area completely covers the section area, determining that the steering wheel does not block the sight channel;

[0058] When the hollow area does not completely cover the cross-section area, it is determined that the steering wheel blocks the visual channel.

[0059] Specifically, since the driver mainly views the information provided on the instrument screen through the hollow part between the wheel hub and the rim on the steering wheel during driving, when judging whether the steering wheel blocks the line of sight channel based on the line of sight channel and the current position of the steering wheel, first obtain the hollow area of ​​the uppermost hollow part between the rim and the hub of the steering wheel when the steering wheel is in the return position on the plane where the rim of the steering wheel is located, and then obtain the cross-sectional area of ​​the line of sight channel on the plane where the rim of the steering wheel is located. By judging the positional relationship between the hollow area and the cross-sectional area, it can be determined whether the steering wheel blocks the line of sight channel. Among them, when the hollow area completely covers the cross-sectional area, it can be determined that the steering wheel does not block the line of sight channel, and when the hollow area does not completely cover the cross-sectional area, it can be determined that the steering wheel blocks the line of sight channel. Figure 4 As shown, the hollow area 420 does not completely cover the cut surface area 410, which indicates that the steering wheel blocks the visual channel.

[0060] It should be noted that when determining the positional relationship between the hollow area and the cross-sectional area, the target distance from each point on the boundary of the hollow area to the line of sight channel can be calculated, and the positive and negative distance values ​​can be used to indicate the positional relationship between each point and the line of sight channel. If each point on the boundary of the hollow area is outside the line of sight channel, the target distance value is recorded as positive; if the point on the boundary of the hollow area is inside the line of sight channel, the target distance is recorded as negative. In this case, when the target distances corresponding to each point on the boundary of the hollow area are all positive, it can be determined that the hollow area covers the cross-sectional area, and then it can be determined that the steering wheel does not block the line of sight channel.

[0061] The above implementation scheme of the present application realizes determining whether the steering wheel blocks the visual channel based on the positional relationship between the hollow area and the cross-section area, and the judgment method is simple.

[0062] In an optional embodiment of the present application, when the steering wheel blocks the sight line, determining the steering wheel target position according to the sight line and the current position of the steering wheel includes:

[0063] In the case where the hollow area does not completely cover the section area, adjusting the position of the hollow area to obtain a target hollow area, wherein the target hollow area completely covers the section area;

[0064] The steering wheel position corresponding to the target hollow area is determined as the steering wheel target position.

[0065] In the case where the steering wheel blocks the sight channel, that is, when the hollow area on the steering wheel does not completely cover the cross-sectional area corresponding to the sight channel, the position of the hollow area is adjusted, such as Figure 5 As shown, the positional relationship between the adjusted target hollowing area 510 and the cut surface area 410.

[0066] It should be noted that, based on the stored steering wheel data calibrated by the OEM, within the steering wheel adjustment range, each column tilt angle α and the steering wheel center point S coordinate (X, Y, Z) corresponds to a boundary position between the steering wheel rim and the wheel hub. When determining the target hollow area, the area obtained when the distance from the sight channel to the inner circle of the steering wheel rim and the distance from the sight channel to the wheel hub are closest can be determined as the target hollow area.

[0067] After the target hollow area is determined, the steering wheel position corresponding to the target hollow area is determined as the steering wheel target position. When the steering wheel is at the steering wheel target position, the steering wheel will not block the visual channel.

[0068] The above implementation scheme of the present application realizes determining the target hollow area based on the positional relationship between the hollow area and the cross-section area, and then determining the target position of the steering wheel, so that when the steering wheel is in the target position of the steering wheel, the visual channel is not blocked.

[0069] In an optional embodiment of the present application, adjusting the steering wheel from the current steering wheel position to the target steering wheel position includes:

[0070] Determining a steering wheel column adjustment angle and a steering wheel axial adjustment distance according to the current position of the steering wheel and the target position of the steering wheel;

[0071] The position of the steering wheel is adjusted according to the steering wheel column adjustment angle and the steering wheel axial adjustment distance.

[0072] After determining the target position of the steering wheel, the steering wheel column adjustment angle and the steering wheel axial adjustment distance can be determined based on the current position of the steering wheel and the target position of the steering wheel, such as Figure 6 As shown, the column angle corresponding to the current position 601 of the steering wheel is α o , the corresponding axial distance is L1, the corresponding column angle of the steering wheel target position 602 is α c , the corresponding axial distance is L2, then the steering column adjustment angle can be obtained as α c -α o The axial adjustment distance of the steering wheel is L2-L1. The specific angle adjustment direction can be determined according to the positive and negative of the steering wheel column adjustment angle. If the steering wheel column adjustment angle is positive, the steering wheel column angle is increased. If the steering wheel column adjustment angle is negative, the steering wheel column angle is reduced. Accordingly, the specific axial distance adjustment direction can be determined according to the positive and negative of the steering wheel axial adjustment distance. If the steering wheel axial adjustment distance is positive, the steering wheel axial distance is increased. If the steering wheel axial adjustment distance is negative, the steering wheel axial distance is reduced.

[0073] After determining the steering wheel column adjustment angle and the steering wheel axial adjustment distance, the steering wheel adjustment mechanism adjusts the position of the steering wheel based on the steering wheel column adjustment angle and the steering wheel axial adjustment distance, and the adjusted steering wheel position is the steering wheel target position.

[0074] The above implementation scheme of the present application can further determine the steering wheel column adjustment angle and the steering wheel axial adjustment distance after determining the target position of the steering wheel, so that the steering wheel adjustment mechanism can adjust the position of the steering wheel based on the steering wheel column adjustment angle and the steering wheel axial adjustment distance, thereby ensuring that the adjusted steering wheel does not block the line of sight.

[0075] In an optional embodiment of the present application, after determining whether the steering wheel blocks the visual channel, the method further includes:

[0076] In the case where the steering wheel blocks the visual channel, detecting whether the vehicle is in a driving state;

[0077] When the vehicle is in a driving state, adjusting the steering wheel from the current steering wheel position to the steering wheel target position includes:

[0078] When it is detected that the vehicle exits the driving state, the steering wheel is adjusted from the current steering wheel position to the target steering wheel position.

[0079] Specifically, after determining whether the steering wheel blocks the line of sight, if the steering wheel blocks the line of sight, it is also necessary to detect whether the vehicle is in a driving state. If the vehicle is in a driving state, it is necessary to adjust the steering wheel from the initial position of the steering wheel to the target position of the steering wheel when the vehicle exits the driving state. In other words, when the vehicle is in a driving state, it is detected that the steering wheel will block the line of sight at this time. In order to ensure driving safety, the position of the steering wheel is not directly adjusted, but it is necessary to adjust the position of the steering wheel from the current position of the steering wheel to the target position of the steering wheel when the vehicle exits the driving state, that is, the vehicle is in a stationary state, so that the steering wheel does not block the line of sight, so that when the vehicle enters the driving state again, the driver can view all the information on the instrument screen without moving the body or head.

[0080] The above implementation scheme of the present application can detect the driving status of the vehicle, thereby avoiding the automatic adjustment of the steering wheel position while the driver is driving the vehicle, which affects driving safety.

[0081] In an optional embodiment of the present application, before obtaining the sight line channel for the driver to observe the instrument screen and the current position of the steering wheel, the method further includes:

[0082] Obtain the driver's eye position and the historical driver's eye position corresponding to the last steering wheel adjustment;

[0083] Compare the driver's eye position with the historical driver's eye position. When the driver's eye position is different from the historical driver's eye position, execute the step of obtaining the driver's line of sight channel for observing the instrument screen and the current position of the steering wheel. When the driver's eye position is the same as the historical driver's eye position, keep the steering wheel position unchanged.

[0084] Specifically, this embodiment can store the driver's eye position corresponding to the last steering wheel adjustment as the historical driver's eye position, and before obtaining the driver's sight channel for observing the instrument screen and the current position of the steering wheel, compare the driver's eye position with the historical driver's eye position. If they are the same, it indicates that the driver has not been changed, and there is no need to adjust the steering wheel position at this time, and the steering wheel position remains unchanged. If they are not the same, it indicates that the driver has been changed, and it is necessary to obtain the driver's sight channel for observing the instrument screen and the current position of the steering wheel, and further determine whether the steering wheel blocks the sight channel, and if blocked, adjust the steering wheel position.

[0085] The above implementation scheme of the present application determines whether to execute the step of obtaining the driver's line of sight channel for observing the instrument screen and the current position of the steering wheel by comparing the driver's eye position with the historical driver's eye position corresponding to the last steering wheel adjustment. If the driver's eye position is the same as the historical driver's eye position corresponding to the last steering wheel adjustment, it indicates that the current steering wheel position will not block the line of sight channel. Therefore, there is no need to obtain the driver's line of sight channel for observing the instrument screen and the current position of the steering wheel and subsequent operations, thereby improving the intelligence of the adaptive adjustment of the steering wheel.

[0086] The following is an introduction to the steering wheel adjustment system used in the steering wheel adjustment method provided in the embodiment of the present application. Figure 7 As shown, the steering wheel adjustment system includes: a steering wheel sensor 701 , a steering wheel 702 , an algorithm control module 703 , a steering wheel adjustment mechanism 704 , an instrument screen 220 , a first camera 301 and a second camera 302 .

[0087] The overall implementation process of the embodiment of the present application will be introduced below in combination with the functions of each component in the steering wheel adjustment system. Figure 8 As shown, including:

[0088] Step 801, identifying the driving state of the vehicle according to the vehicle state information.

[0089] Step 802, when the vehicle is in motion, the driver's facial image is captured by a camera, feature analysis is performed to identify the eye position, and the image is fed back to the algorithm control module.

[0090] Step 803: construct a virtual sight line channel according to the coordinates of the driver's eye position and the coordinates of the display boundary vertices of the instrument screen.

[0091] Step 804: When the vehicle is in driving state, the steering wheel sensor collects the initial position of the steering wheel and feeds it back to the algorithm control module.

[0092] Step 805: the algorithm control module calculates the distance between the driver's sight channel and the steering wheel rim and the wheel hub to determine whether the steering wheel blocks the sight channel.

[0093] Step 806, when the steering wheel blocks the sight line, based on the steering wheel data stored in the algorithm control module by the OEM in the early stage, calculate the column tilt angle and the steering wheel center point coordinates corresponding to the steering wheel when the distance from the sight line to the wheel rim is approximately equal to the distance from the sight line to the wheel hub.

[0094] Step 807: The steering wheel adjustment mechanism adjusts the coordinate position of the center point of the steering wheel through angle adjustment and axial adjustment.

[0095] The above implementation scheme obtains the driver's line of sight channel for observing the instrument screen and the current position of the steering wheel, and when the steering wheel blocks the line of sight channel, determines the steering wheel target position corresponding to the steering wheel not blocking the line of sight channel, and adjusts the position of the steering wheel to the steering wheel target position. When the steering wheel blocks the driver's observation of the instrument screen, the position of the steering wheel can be automatically adjusted so that the steering wheel does not block the driver's observation of the instrument screen, thereby improving the intelligence of the vehicle cockpit and user experience.
