[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0031] It should be understood that the “one embodiment” or “an embodiment” mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, “in one embodiment” or “in an embodiment” appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0032] In various embodiments of the present application, it should be understood that the size of the serial number of each process does not mean the execution order, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0033] As shown in Figure 1 The embodiments of the present application provide a steering wheel adjusting method, which comprises the following steps:

[0034] In step 101, the line-of-sight channel of the driver observation instrument screen and the current position of the steering wheel are acquired.

[0035] The line-of-sight channel herein is a line-of-sight channel corresponding to the eyes of the driver observing the instrument screen when the driver sits at the driving position and looks forward. The line-of-sight channel is a three-dimensional spatial structure. Specifically, the position of the eyes of the driver can be acquired by an image acquisition device, and then the line-of-sight channel of the driver observing the instrument screen can be determined based on the acquired position of the eyes of the driver and the position of the instrument screen.

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

[0037] Step 102: determining whether the steering wheel blocks the line-of-sight channel according to the line-of-sight 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 part between the hub and the rim of the steering wheel during driving of the vehicle, the line-of-sight channel of the driver observing the instrument screen and the current position of the steering wheel are acquired, and then whether the steering wheel blocks the line-of-sight channel, that is, whether the hub and the rim of the steering wheel block the line-of-sight channel, is determined according to 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, the driver can view the information provided on the instrument screen completely through the hollow part between the hub and the rim of the steering wheel. When the steering wheel blocks the line-of-sight channel, the driver cannot view all the information provided on the instrument screen completely through the hollow part between the hub and the rim of the steering wheel. At this time, if the driver needs to view the information on the instrument screen blocked by the hub and / or the rim of the steering wheel, the driver needs to move the body or the head.

[0039] Step 103: determining a target position of the steering wheel according to the line-of-sight channel and the current position of the steering wheel when the steering wheel blocks the line-of-sight channel, so that the steering wheel does not block the line-of-sight channel when the steering wheel is located at the target position of the steering wheel.

[0040] When it is determined that the steering wheel blocks the line-of-sight channel, it indicates that the steering wheel blocks the line-of-sight channel of the driver observing the instrument screen when the steering wheel is at the current position. At this time, the position of the steering wheel can be adjusted so that the steering wheel does not block the line-of-sight channel of the driver observing the instrument screen. Therefore, a target position of the steering wheel is determined, so that the steering wheel does not block the line-of-sight channel of the driver observing the instrument screen when the steering wheel is located at the target position of the steering wheel.

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

[0042] After the target position of the steering wheel is determined, the current position of the steering wheel is adjusted to the target position of the steering wheel, so that the steering wheel does not block the line-of-sight channel of the driver for observing the instrument screen.

[0043] In the embodiments of the present application, the line-of-sight channel of the driver for observing the instrument screen and the current position of the steering wheel are obtained, and when the steering wheel blocks the line-of-sight channel, the target position of the steering wheel corresponding to the line-of-sight channel not being blocked by the steering wheel is determined, and the position of the steering wheel is adjusted to the target position of the steering wheel, so that the position of the steering wheel can be automatically adjusted when the steering wheel blocks the instrument screen of the driver, and the steering wheel does not block the instrument screen of the driver, thereby improving the intelligence and user experience of the vehicle cabin.

[0044] In an optional embodiment of the present application, the line-of-sight channel of the driver for observing the instrument screen comprises:

[0045] The first position corresponding to the left eye of the driver and the second position corresponding to the right eye of the driver are obtained.

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

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

[0048] In the above embodiments of the present application, the space formed by the line connecting the first position corresponding to the left eye and the two vertices on the right side of the instrument screen and the line connecting the second position corresponding to the right eye and the two vertices on the left side of the instrument screen is determined as the line-of-sight channel, so that whether the steering wheel blocks the driver for observing the instrument screen can be determined based on the line-of-sight channel.

[0049] In an optional embodiment of the present application, the first position corresponding to the left eye of the driver and the second position corresponding to the right eye of the driver are obtained, comprising:

[0050] The face image of the driver is obtained through an image acquisition device.

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

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

[0053] According to the above embodiments of the present application, the first position and the second position are obtained by identifying the eyes on the acquired face image of the driver, so that the positioning of the eye position of the driver is more accurate.

[0054] In an optional embodiment of the present application, according to the line-of-sight channel and the current position of the steering wheel, it is determined whether the steering wheel blocks the line-of-sight channel, comprising:

[0055] acquiring a hollow region of the steering wheel rim on the plane where the steering wheel rim is located, which is the hollow part between the steering wheel rim and the hub when the steering wheel is in the neutral position;

[0056] acquiring a cross-sectional region of the line-of-sight channel on the plane where the steering wheel rim is located;

[0057] in the case that the hollow region completely covers the cross-sectional region, it is determined that the steering wheel does not block the line-of-sight channel;

[0058] in the case that the hollow region does not completely cover the cross-sectional region, it is determined that the steering wheel blocks the line-of-sight channel.

[0059] Specifically, since the driver mainly views the information provided on the instrument screen through the hollow part between the hub and the rim of the steering wheel during driving, when determining whether the steering wheel blocks the line-of-sight channel according to the line-of-sight channel and the current position of the steering wheel, first, the hollow region of the steering wheel rim on the plane where the steering wheel rim is located, which is the hollow part between the steering wheel rim and the hub when the steering wheel is in the neutral position, is acquired, and then the cross-sectional region of the line-of-sight channel on the plane where the steering wheel rim is located is acquired, and the positional relationship between the hollow region and the cross-sectional region is determined to determine whether the steering wheel blocks the line-of-sight channel. Wherein, when the hollow region completely covers the cross-sectional region, it is determined that the steering wheel does not block the line-of-sight channel, and when the hollow region does not completely cover the cross-sectional region, it is determined that the steering wheel blocks the line-of-sight channel. For example, Figure 4 As shown, the hollow region 420 does not completely cover the cross-sectional region 410, which indicates that the steering wheel blocks the line-of-sight channel.

[0060] It should be noted that when determining the positional relationship between the hollow region and the tangent region, the distance from each point on the boundary of the hollow region to the target distance of the line-of-sight channel can be calculated, and the positive and negative of the distance value can indicate the positional relationship of each point to the line-of-sight channel. If each point on the boundary of the hollow region is located outside the line-of-sight channel, the target distance value is positive. If the point on the boundary of the hollow region is located inside the line-of-sight channel, the target distance is negative. In the case that the target distance corresponding to each point on the boundary of the hollow region is positive, it can be determined that the hollow region covers the tangent region, and further that the steering wheel does not block the line-of-sight channel.

[0061] The above-mentioned embodiments of the present application achieve the determination of whether the steering wheel blocks the line-of-sight channel based on the positional relationship between the hollow region and the tangent region, and the determination method is simple.

[0062] In an optional embodiment of the present application, in the case that the steering wheel blocks the line-of-sight channel, the target position of the steering wheel is determined according to the current position of the line-of-sight channel and the steering wheel, comprising:

[0063] In the case that the hollow region does not completely cover the tangent region, the position of the hollow region is adjusted to obtain a target hollow region, and the target hollow region completely covers the tangent region.

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

[0065] In the case that the steering wheel blocks the line-of-sight channel, that is, the hollow region on the steering wheel does not completely cover the tangent region corresponding to the line-of-sight channel, the position of the hollow region is adjusted, as shown in FIG. 5, the positional relationship between the adjusted target hollow region 510 and the tangent region 410. Figure 5

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

[0067] After determining the target hollow region, the position of the steering wheel corresponding to the target hollow region is determined as the target position of the steering wheel. When the steering wheel is in the target position of the steering wheel, the steering wheel does not block the line-of-sight channel.

[0068] ​The above-mentioned embodiments of the present application achieve the determination of the target hollow area based on the positional relationship between the hollow area and the tangent area, and further determine the target position of the steering wheel, so that the steering wheel is in the target position and does not block the line of sight.

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

[0070] Determining the steering column adjustment angle and the axial adjustment distance of the steering wheel based on the current position of the steering wheel and the target position of the steering wheel;

[0071] Adjusting the position of the steering wheel based on the steering column adjustment angle and the axial adjustment distance of the steering wheel.

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

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

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

[0075] In an optional embodiment of the present application, after judging whether the steering wheel shields the line-of-sight channel, the method further comprises:

[0076] In the case that the steering wheel shields the line-of-sight channel, detecting whether the vehicle is in a driving state;

[0077] In the case that the vehicle is in the driving state, the adjusting the steering wheel from the current position of the steering wheel to the target position of the steering wheel comprises:

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

[0079] Specifically, after judging whether the steering wheel shields the line-of-sight channel, if the steering wheel shields the line-of-sight channel, it is further needed to detect whether the vehicle is in a driving state, and if the vehicle is in the driving state, it is needed 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. That is to say, in the case that the vehicle is in the driving state, it is detected that the steering wheel shields the line-of-sight channel at this time, in order to ensure driving safety, the position of the steering wheel is not directly adjusted, but the position of the steering wheel is adjusted from the current position of the steering wheel to the target position of the steering wheel when the vehicle exits the driving state, i.e., the vehicle is in a static state, so that the steering wheel does not shield the line-of-sight channel, thereby the driver can view all information of the instrument screen without moving the body or the head when the vehicle enters the driving state again.

[0080] According to the above-mentioned embodiments of the present application, by detecting the driving state of the vehicle, it can be avoided that the position of the steering wheel is automatically adjusted during the driving of the vehicle by the driver, thereby affecting driving safety.

[0081] In an optional embodiment of the present application, before acquiring the line-of-sight channel of the driver observing the instrument screen and the current position of the steering wheel, the method further comprises:

[0082] Acquiring the position of the eyes of the driver and a historical position of the eyes of the driver corresponding to the last adjustment of the steering wheel;

[0083] Comparing the position of the eyes of the driver and the historical position of the eyes of the driver, and if the position of the eyes of the driver and the historical position of the eyes of the driver are different, performing the step of acquiring the line-of-sight channel of the driver observing the instrument screen and the current position of the steering wheel, and if the position of the eyes of the driver and the historical position of the eyes of the driver are the same, keeping the position of the steering wheel unchanged.

[0084] Specifically, the embodiment can store the driver's eye position corresponding to the last steering wheel adjustment as a historical driver's eye position, and compare the driver's eye position with the historical driver's eye position before obtaining the line-of-sight channel of the driver's observation instrument screen and the current position of the steering wheel. If they are the same, it indicates that the driver has not been replaced, and at this time, the position of the steering wheel does not need to be adjusted, and the position of the steering wheel is kept unchanged. If they are not the same, it indicates that the driver has been replaced, and at this time, the line-of-sight channel of the driver's observation instrument screen and the current position of the steering wheel need to be obtained, and further determine whether the steering wheel blocks the line-of-sight channel, and adjust the position of the steering wheel in the case of blocking.

[0085] The above embodiment of the application determines whether to perform the step of obtaining the line-of-sight channel of the driver's observation 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 and the historical driver's eye position corresponding to the last steering wheel adjustment are the same, it indicates that the current position of the steering wheel will not block the line-of-sight channel, so there is no need to obtain the line-of-sight channel of the driver's observation instrument screen and the current position of the steering wheel and subsequent operations, which improves the intelligence of the adaptive adjustment of the steering wheel.

[0086] The steering wheel adjustment system to which the steering wheel adjustment method provided by the embodiment of the application is applied will be introduced below, as shown in Figure 7 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 application will be introduced below in combination with the functions of the components in the steering wheel adjustment system, as shown in Figure 8 The overall implementation process of the embodiment of the application will be introduced below in combination with the functions of the components in the steering wheel adjustment system, as shown in

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

[0089] Step 802, when the vehicle is in the driving state, collecting the driver's face image through the camera, performing feature analysis to identify the eye position, and feeding back to the algorithm control module.

[0090] Step 803, constructing a virtual line-of-sight channel according to the driver's eye position coordinates and the display boundary vertex coordinates of the instrument screen.

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

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

[0093] Step 806, in the case that the steering wheel blocks the line of sight channel, the steering wheel data stored in the algorithm control module by the host manufacturer in advance is used to calculate the corresponding column tilt angle and the steering wheel center point coordinates when the distance from the line of sight channel to the rim is approximately equal to the distance from the line of sight channel to the hub.

[0094] Step 807, the steering wheel adjusting mechanism adjusts the position of the steering wheel center point coordinates through angle adjustment and axial adjustment.

[0095] The above embodiment can automatically adjust the position of the steering wheel when the steering wheel blocks the driver's observation instrument screen, so that the steering wheel does not block the driver's observation instrument screen, thereby improving the intelligence and user experience of the vehicle cabin.
