[0056] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] A steering wheel is a wheel-shaped device used to steer a vehicle. It's part of the vehicle's steering system, controlling the vehicle's direction by transferring driver-input torque to the steering shaft. The steering wheel is the control device for the vehicle's steering system, directly receiving driver input and providing feedback on the vehicle's road conditions through contact with the driver.

[0058] A steering wheel is generally wheel-shaped and has various dimensional parameters. The surface where the steering wheel spokes are located is called the steering wheel face. Accordingly, the dimensions of the steering wheel face are called the face size. In related art, the face size of a steering wheel can be adjusted by changing the length of the steering wheel spokes or other methods.

[0059] The first aspect of this application proposes an embodiment, such as Figure 1 A method for adjusting the size of a steering wheel is shown in the step diagram, and the method is applied to an on-board controller, comprising:

[0060] Step S101: When a target person is detected outside a main vehicle door, the arm span of the target person is obtained.

[0061] Wing span is the distance between the left and right fingertips when the arms are extended and parallel to the ground. In ergonomics, arm span reflects a driver's comfort level with steering wheels of varying wheel sizes. For example, a driver with a larger arm span would be suited to a larger steering wheel, while a driver with a smaller arm span would be suited to a smaller steering wheel.

[0062] The main driver's door refers to the door closest to the vehicle's main driver's seat. Taking a left-hand drive four-door vehicle as an example, the main driver's door is the door located at the front left side of the vehicle.

[0063] A target person is someone who intends to drive a vehicle and has been identified by the vehicle as having a legitimate identity. This person can be detected using devices such as cameras or smart key detectors. For example, if a camera detects a person's facial features that match those pre-stored in a legal identity database, the person is identified as the target person. Alternatively, a smart key detector can be used to detect the location of a smart key. If the smart key detector detects that the person is carrying a smart key, the person is identified as the target person.

[0064] When the vehicle is unlocked, when a target person is detected within a preset range outside the main driving door by a camera or smart key detector, the arm span of the target person should be obtained to ensure that the steering wheel size is ergonomic.

[0065] Step S102: determining a first surface size of the steering wheel based on the arm span.

[0066] The steering wheel surface size is the diameter or radius of the steering wheel surface. In ergonomics, the steering wheel surface size should conform to the relationship coefficient L between arm span and surface size, so as to determine the surface size that is objectively suitable for the driver based on the arm span. Taking the vehicle's arm span as an example, the first surface size R of the steering wheel determined based on the arm span is 臂展 The calculation formula is:

[0067] R 臂展 =L*m

[0068] Among them, R 臂展 is the first disk size, L is the relationship coefficient between arm span and disk size, and m is the target person’s arm span.

[0069] Substituting the obtained arm span into the calculation formula of the first steering wheel surface size, the steering wheel surface size determined based on the arm span, that is, the first steering wheel surface size, can be obtained.

[0070] Step S103 , in response to the triggering of the power-on signal, determining the current driving mode of the vehicle.

[0071] Driving mode refers to the different response modes of a vehicle to the same driver action during driving. Driving modes are generally divided into performance mode, economy mode, comfort mode and normal mode. Vehicles in different modes respond differently to the same driver action. For example, if the driver steps on the accelerator pedal at the same speed in different driving modes, when the vehicle is in performance mode, the accelerator pedal is more sensitive and responds more quickly to the driver's pedaling action, which can fully meet the driver's control needs of the vehicle; when the vehicle is in comfort mode, the accelerator pedal reacts more slowly, causing a delay in the response to the driver's pedaling action, thereby avoiding sudden acceleration of the vehicle and improving the smoothness of the vehicle's driving.

[0072] When triggered by a power-on signal, the vehicle controller can obtain the current driving mode of the vehicle through the driving mode control module connected to it.

[0073] Step S104: Based on the current driving mode, the first steering wheel size is adjusted to obtain a second steering wheel size.

[0074] Different driving modes reflect different drivers' preferences. For example, drivers using Performance mode prefer precise vehicle control and prioritize steering flexibility; drivers using Comfort mode prefer comfortable vehicle control and prioritize steering control. Drivers using Normal mode fall somewhere in between.

[0075] Therefore, on the basis of the first wheel size obtained based on the arm length, the driver's subjective preference should also be determined through the current driving mode, and then the first wheel size should be adjusted to obtain the second wheel size, and then on the basis of ergonomics, the steering wheel size that meets the driver's subjective preference is obtained.

[0076] Step S105: adjusting the steering wheel surface size to the second steering wheel surface size.

[0077] Taking a related art steering wheel in which the steering wheel surface size is adjusted by changing the length of the steering wheel spokes as an example, the steering wheel surface size can be adjusted to a second steering wheel surface size in the following manner. Specifically, based on the second steering wheel surface size determined based on the arm length and the driving mode, a target spoke length corresponding to the second steering wheel surface size is determined. The steering wheel surface size is then adjusted to the second steering wheel surface size by adjusting the length of the steering wheel spokes to the target spoke length.

[0078] This embodiment, based on a first steering wheel size determined based on arm span, adjusts the first steering wheel size according to the vehicle's driving mode to obtain a second steering wheel size, and then adjusts the vehicle's steering wheel size to the second steering wheel size. This embodiment infers the user's subjective steering wheel size preference by obtaining the vehicle's driving mode, and then adjusts the steering wheel size to a size that meets the user's subjective preference based on the driving mode, thereby satisfying the user's subjective steering wheel size preference and improving the user's driving experience.

[0079] The second aspect of the present application provides an embodiment. In addition to the method described in the first aspect, this embodiment also includes:

[0080] Alternatively, as Figure 2 As shown in the figure, a method for obtaining the arm span of a target person includes: step S101:

[0081] Step S1011, obtaining the region and height of the target person.

[0082] The target person's height can be obtained in various ways, such as through a radar detector installed on the vehicle. During the radar detection process, the highest height detected should be determined as the target person's height. The target person's location can be obtained in various ways, such as through the vehicle's sales region. The sales region can be determined by the vehicle's system software version or directly from the vehicle's sales region entered on the vehicle. Once the vehicle's sales region is determined, the vehicle's country of origin can be determined from the sales region, and the target person's location can be determined.

[0083] Step S1012: determining a target coefficient corresponding to the region of the target person according to the region of the target person.

[0084] Generally speaking, the dimensions of various parts of the human body are proportional to each other. For example, shoulder width is generally equal to twice the width of the head. Therefore, knowing the coefficient of the proportional relationship between height and arm span can be used to determine the target person's arm length based on their height.

[0085] At the same time, due to the influence of different geographical environments and lifestyles, different people living in different regions and countries have different height-to-arm span ratios. Therefore, in order to improve the adaptability of the driver to the steering wheel size, the height-to-arm span ratio corresponding to the current region can be determined based on the target person's current location. The height-to-arm span ratio corresponding to the region is the target coefficient. For example, if the vehicle is currently in Europe, the height-to-arm span ratio of people in Europe should be determined as the target coefficient when the vehicle is in Europe.

[0086] Step S1013: Determine the arm span of the target person based on the target coefficient and the height.

[0087] Use big data to calculate the target coefficient F(x) that represents the relationship between the height and arm span of people in different regions. After obtaining the target person's height h and determining the target coefficient F(x) corresponding to the region based on the target person's current region, substitute the height h and target coefficient F(x) into the calculation formula of arm span m to obtain the target person's arm span m.

[0088] Specifically, the calculation formula for the target person's arm span m is:

[0089] m=F(x)*h

[0090] Where m is the target person's arm span, F(x) is the target coefficient, and h is the target person's height.

[0091] Furthermore, the calculation formula of the target person's arm span m is substituted into the first disk size R 臂展 The calculation formula of the first disk size R can be obtained based on the height h of the target person. 臂展 The calculation formula is:

[0092] R 臂展 =L*F(x)*h

[0093] Among them, R 臂展 is the first disk size, L is the relationship coefficient between arm span and disk size, F(x) is the target coefficient, and h is the height of the target person.

[0094] Alternatively, as Figure 3 As shown in the figure, a method for obtaining the height of a target person includes: step S1011:

[0095] Step 11: Obtain the identity information of the target person.

[0096] The target person's identity information refers to information used to identify the target person and distinguish them from other people, such as the target person's facial features, fingerprints, or voice. Different methods can be used to obtain different types of identity information. For example, when the identity information is facial features, a camera can be used to obtain it; when the identity information is fingerprints, a fingerprint recognition device can be used to obtain it.

[0097] Step 12: Match the identity information of the target person with pre-stored identity information in a height information database, wherein the height information database stores heights corresponding to a plurality of pre-stored identity information.

[0098] The height information database is pre-stored in the vehicle controller and contains pre-stored identity information and the height corresponding to each pre-stored identity information. The pre-stored identity information in the height information database can be pre-entered by the user or verified as legitimate from historical data. Correspondingly, the height corresponding to the pre-stored identity information can also be directly entered by the user or collected through a radar detector installed on the vehicle.

[0099] Step 13: Determine the height of the target person based on the height corresponding to the pre-stored identity information that matches the identity information.

[0100] The obtained identity information of the target person is matched with the pre-stored identity information in the height information database. If the pre-stored identity information in the identity information database matches the identity information of the target person, the height corresponding to the pre-stored identity information in the match is determined as the height of the target person.

[0101] Alternatively, as Figure 4 As shown in the step diagram of the method for adjusting the size of the steering wheel in stages, the method includes:

[0102] Step S201: When a target person is detected outside the main vehicle door, the arm span of the target person is obtained.

[0103] Wing span is the distance between the left and right fingertips when the arms are extended and parallel to the ground. In ergonomics, arm span reflects a driver's comfort level with steering wheels of varying wheel sizes. For example, a driver with a larger arm span would be suited to a larger steering wheel, while a driver with a smaller arm span would be suited to a smaller steering wheel.

[0104] The main driver's door refers to the door closest to the vehicle's main driver's seat. Taking a left-hand drive four-door vehicle as an example, the main driver's door is the door located at the front left side of the vehicle.

[0105] A target person is someone who intends to drive a vehicle and has been identified by the vehicle as having a legitimate identity. This person can be detected using devices such as cameras or smart key detectors. For example, if a camera detects a person's facial features that match those pre-stored in a legal identity database, the person is identified as the target person. Alternatively, a smart key detector can be used to detect the location of a smart key. If the smart key detector detects that the person is carrying a smart key, the person is identified as the target person.

[0106] When the vehicle is unlocked, when a target person is detected within a preset range outside the main driving door by a camera or smart key detector, the arm span of the target person should be obtained to ensure that the steering wheel size is ergonomic.

[0107] Step S202: Determine a first surface size of the steering wheel based on the arm span.

[0108] The steering wheel surface size is the diameter or radius of the steering wheel surface. In ergonomics, the steering wheel surface size should conform to the relationship coefficient L between arm span and surface size, so as to determine the surface size that is objectively suitable for the driver based on the arm span. Taking the vehicle's arm span as an example, the first surface size R of the steering wheel determined based on the arm span is 臂展 The calculation formula is:

[0109] R 臂展 =L*m

[0110] Among them, R 臂展 is the first disk size, L is the relationship coefficient between arm span and disk size, and m is the target person’s arm span.

[0111] Substituting the obtained arm span into the calculation formula of the first steering wheel surface size, the steering wheel surface size determined based on the arm span, that is, the first steering wheel surface size, can be obtained.

[0112] Step S203: Detect whether there is an occupant in the driver's seat of the vehicle.

[0113] In one specific embodiment, to allow the driver to feel the steering wheel's size change before the vehicle is powered on, the steering wheel's size can be adjusted in stages. After determining the initial steering wheel size, the presence of an occupant in the driver's seat is detected to determine whether adjusting the steering wheel's size will negatively impact the driver's control.

[0114] For example, if there is a passenger in the main driver's seat of the vehicle (the passenger in the main driver's seat is the driver by default), in this case, if the steering wheel is adjusted based on the arm span of the target person detected outside the vehicle, the adjusted steering wheel size will obviously not match the driver's arm span. Therefore, before the first stage of adjusting the steering wheel size, it is necessary to first detect whether there is a passenger in the main driver's seat of the vehicle to avoid negative impact on the driver's operation after adjusting the steering wheel size.

[0115] Step S204: When it is detected that there is no occupant in the driver's seat and the driver's door is open, the steering wheel size is adjusted to a first steering wheel size.

[0116] If no occupant is detected in the driver's seat, the steering wheel size is adjusted. Since there is no driver inside the vehicle at this time, there will be no negative impact on the driver's operation. In this case, if the driver's door is opened, it indicates that the target person has entered the vehicle and needs to experience the steering wheel size change. Therefore, if no occupant is detected in the driver's seat and the driver's door is opened, the first stage of steering wheel size adjustment should be performed, that is, the steering wheel size should be adjusted to the first size.

[0117] Step S205 , in response to the triggering of the power-on signal, determining the current driving mode of the vehicle.

[0118] Driving mode refers to the different response modes of a vehicle to the same driver action during driving. Driving modes are generally divided into performance mode, economy mode, comfort mode and normal mode. Vehicles in different modes respond differently to the same driver action. For example, if the driver steps on the accelerator pedal at the same speed in different driving modes, when the vehicle is in performance mode, the accelerator pedal is more sensitive and responds more quickly to the driver's pedaling action, which can fully meet the driver's control needs of the vehicle; when the vehicle is in comfort mode, the accelerator pedal reacts more slowly, causing a delay in the response to the driver's pedaling action, thereby avoiding sudden acceleration of the vehicle and improving the smoothness of the vehicle's driving.

[0119] When triggered by a power-on signal, the vehicle controller can obtain the current driving mode of the vehicle through the driving mode control module connected to it.

[0120] Step S206: Based on the current driving mode, the first steering wheel size is adjusted to obtain a second steering wheel size.

[0121] Different driving modes reflect different drivers' preferences. For example, drivers using Performance mode prefer precise vehicle control and prioritize steering flexibility; drivers using Comfort mode prefer comfortable vehicle control and prioritize steering control. Drivers using Normal mode fall somewhere in between.

[0122] Therefore, on the basis of the first wheel size obtained based on the arm length, the driver's subjective preference should also be determined through the current driving mode, and then the first wheel size should be adjusted to obtain the second wheel size, and then on the basis of ergonomics, the steering wheel size that meets the driver's subjective preference is obtained.

[0123] Step S207: Adjust the steering wheel surface size to the second steering wheel surface size.

[0124] Taking a related art steering wheel in which the steering wheel surface size is adjusted by changing the length of the steering wheel spokes as an example, the steering wheel surface size can be adjusted to a second steering wheel surface size in the following manner. Specifically, based on the second steering wheel surface size determined based on the arm length and the driving mode, a target spoke length corresponding to the second steering wheel surface size is determined. The steering wheel surface size is then adjusted to the second steering wheel surface size by adjusting the length of the steering wheel spokes to the target spoke length.

[0125] Alternatively, as Figure 5 As shown in the figure, a method for obtaining the current driving mode includes: step S103:

[0126] Step S1031 , in response to the triggering of the power-on signal, starting a first countdown of a preset first duration.

[0127] The process of adjusting the steering wheel size involves the movement and coordination of multiple components. In order to avoid frequent adjustment of the steering wheel size, which will reduce the service life of the steering wheel and increase the failure rate, the first countdown with a preset first duration is started when triggered by the power-on signal.

[0128] Step S1032: If no driving mode switching signal is received during the first countdown, then at the end of the first countdown, the current driving mode of the vehicle is determined as the current driving mode.

[0129] During the first countdown, if no driving mode switching signal is received, the current driving mode of the vehicle is determined as the current driving mode, and a buffer time is set between receiving the power-on signal and obtaining the current driving mode under the triggering of the power-on signal to avoid frequent adjustment of the disk size.

[0130] Optionally, refer to Figure 5 , step S103 further includes:

[0131] Step S1033: If a driving mode switching signal is received, a second countdown of a preset second duration is started.

[0132] If a driving mode switching signal is received, the second countdown with a preset second duration is started under the triggering of the driving mode switching signal, thereby preventing the user from switching the driving mode in a short period of time, which leads to frequent adjustment of the disk size.

[0133] Step S1034: During the second countdown, if the driving mode switching signal is not received again, at the end of the second countdown, the driving mode corresponding to the driving mode switching signal that triggered the second countdown will be determined as the current driving mode.

[0134] During the second countdown, if the driving mode switching signal is not received again, indicating that the driver does not frequently switch driving modes, the driving mode switching signal for the second countdown will be turned on at the end of the second countdown, and the corresponding driving mode will be determined as the current driving mode.

[0135] For example, when a driving mode switch signal is received for the first time, a first second countdown begins. If, during the first second countdown, a second driving mode switch signal is received three seconds after the first reception of the driving mode switch signal (assuming the preset second duration is 5 seconds), a second second countdown begins. If no driving mode switch signal is received again during the second countdown, the driving mode corresponding to the second received driving mode switch signal, which triggered the start of the second second countdown, is determined as the current driving mode.

[0136] Alternatively, as Figure 6 A method for adjusting the size of a first disk is shown in the figure, and the method includes:

[0137] Step S1041: Determine the accelerator pedal sensitivity coefficient corresponding to the driving mode.

[0138] Step S1042: Determine the disk size correction amount based on the accelerator pedal sensitivity coefficient.

[0139] The vehicle's accelerator pedal has different sensitivities in different driving modes. Specifically, the coefficient representing the accelerator pedal's sensitivity varies. To accommodate the varying accelerator pedal sensitivity coefficients in different driving modes, the first dial size can be adjusted based on the accelerator pedal sensitivity coefficients to achieve a dial size that meets the driver's subjective preference.

[0140] The disk size correction value refers to the adjustment value of the disk size based on the first disk size. Different accelerator pedal sensitivity coefficients correspond to different disk size correction values. Specifically, the disk size correction value n 修正量 The disk size correction amount n 修正量 The calculation formula is determined.

[0141] Disk size correction amount n 修正量 The calculation formula is:

[0142] n 修正量 =γ*(M y -1)

[0143] Among them, n 修正量 is the disk size correction value, γ is the correction gain coefficient, M y is the accelerator pedal sensitivity coefficient.

[0144] Step S1043: adjusting the first disk size according to the difference between the first disk size and the disk size correction amount.

[0145] After the first steering wheel surface size is adjusted, the obtained steering wheel surface size is the second steering wheel surface size, and the second steering wheel surface size is the difference between the first steering wheel surface size and the steering wheel surface size correction amount.

[0146] Specifically, the second disk size R 驾驶模式 The calculation formula is:

[0147] R 驾驶模式 =R 臂展 -n 修正量

[0148] Among them, R 驾驶模式 is the second disk size, R 臂展 is the first disk size, n 修正量 is the disk size correction amount.

[0149] Furthermore, the disk size correction amount n 修正量 Substitute the calculation formula of the second disk size R 驾驶模式 The calculation formula of the accelerator pedal sensitivity coefficient M can be obtained. y Determine the second disk size R 驾驶模式 The calculation formula is:

[0150] R 驾驶模式 =R 臂展 -γ*(M y -1)

[0151] Among them, R 驾驶模式 is the second disk size, R 臂展 is the size of the first disk, γ is the correction gain coefficient, My is the accelerator pedal sensitivity coefficient.

[0152] The third aspect of this application proposes an embodiment, such as Figure 7 As shown in the flowchart of a method for adjusting the size of a steering wheel, the method includes:

[0153] When the vehicle is unlocked, if a target person is detected outside the main driving door, the target person's arm span is obtained. Specifically, the target person's arm span can be calculated based on the target person's height and a target coefficient, where the target coefficient refers to the ratio of height to arm span determined based on the vehicle's current sales area. The target person's height can be obtained in a variety of ways, such as obtaining the height corresponding to pre-stored identity information that matches the target person's identity information from a height information database based on the target person's identity information; or directly collecting the height using a camera installed on the vehicle body.

[0154] The first steering wheel size is calculated based on the acquired arm span of the target person and the relationship coefficient between the arm span and the steering wheel size.

[0155] After obtaining the first steering wheel size, check whether there is an occupant in the vehicle's main driver's seat. If it is detected that there is no occupant in the main driver's seat, if the main driving door is open, adjust the steering wheel size to the first steering wheel size; if it is detected that there is an occupant in the main driver's seat, end the process.

[0156] After obtaining the first disk size, if a power-on signal is received, the current driving mode of the vehicle is obtained under the triggering of the power-on signal, and the second disk size is calculated based on the current driving mode, specifically including:

[0157] Upon triggering the power-on signal, a first countdown is initiated. If no driving mode switch signal is received by the end of the first countdown, the vehicle's current driving mode is determined as the current driving mode. For example, assuming the first preset duration of the first countdown is 3 seconds and the vehicle's current driving mode is performance mode, then if no driving mode switch signal is received by the end of the first countdown, i.e., 3 seconds after receiving the power-on signal, the performance mode is determined as the current driving mode.

[0158] After receiving the power-on signal, if a driving mode switch signal is received, a second countdown begins. If no driving mode switch signal is received at the end of the second countdown, the driving mode indicated by the driving mode switch signal that triggered the second countdown is determined as the current driving mode. For example, with a preset second duration of 5 seconds for the second countdown, if a driving mode switch signal indicating a switch to comfort mode is received after receiving the power-on signal, the second countdown begins. If no driving mode switch signal is received at the end of the second countdown, i.e., 5 seconds after receiving the driving mode switch signal, the driving mode indicated by the driving mode switch signal that triggered the second countdown, i.e., comfort mode, is determined as the current driving mode.

[0159] If a driving mode switching signal is received again after a driving mode switching signal is received, the second countdown is restarted. For example, the first second countdown begins when the driving mode switching signal is first received. If a driving mode switching signal is received a second time during the first second countdown, for example, three seconds after the first driving mode switching signal was received, a second second countdown begins. If no driving mode switching signal is received again during the second countdown, the driving mode corresponding to the second driving mode switching signal received, which triggered the second countdown, is determined as the current driving mode.

[0160] After determining the current driving mode of the vehicle, the first dial size is adjusted based on the accelerator pedal sensitivity coefficient corresponding to the current driving mode of the vehicle to obtain the second dial size, and the steering wheel size is adjusted based on the second dial size.

[0170] Optionally, the acquisition module is also used to start a first countdown of a preset first duration in response to the triggering of the power-on signal; during the first countdown, if no driving mode switching signal is received, then at the end of the first countdown, the current driving mode of the vehicle is determined as the current driving mode.

[0171] Optionally, the acquisition module is further configured to start a second countdown of a preset second duration if the driving mode switching signal is received; during the second countdown, if the driving mode switching signal is not received again, at the end of the second countdown, the driving mode corresponding to the driving mode switching signal that triggered the start of the second countdown will be determined as the current driving mode.
