Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0049] Figure 2 This is a structural diagram of a steering wheel control device provided in an embodiment of the present invention;

[0050] Figure 3 This is a structural diagram of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Figure 1This is a flowchart of the steps of a steering wheel control method provided in an embodiment of the present invention, as follows: Figure 1 As shown, the method may include the following steps:

[0053] Step 101: Obtain the driver's posture information and the driver's physiological state.

[0054] Step 102: Control the position and orientation of the vehicle's steering wheel based on the posture information.

[0055] And, step 103, generating a feedback signal based on the physiological state and outputting the feedback signal.

[0056] Regarding steps 101-103 above, the embodiments of the present invention can be applied to any vehicle that requires steering wheel control. The steering wheel is an important component of the vehicle, allowing the driver to control the vehicle's direction of travel. The steering wheel's position refers to its longitudinal position and angle, with the longitudinal direction referring to the vehicle's direction of travel.

[0057] It is understandable that different drivers have different driving habits, and different steering wheel positions also affect the driver's driving state. Based on this, embodiments of the present invention can acquire the driver's posture information and control the steering wheel position according to the posture information.

[0058] The aforementioned driver posture information refers to longitudinal posture and / or lateral posture. Lateral posture refers to a direction parallel to the ground and perpendicular to the longitudinal direction. Correspondingly, the longitudinal posture characterizes the relative distance between the driver and the steering wheel in the longitudinal direction, and the lateral posture characterizes the relative distance between the driver and the center point of the steering wheel in the lateral direction. Therefore, the aforementioned posture information can be forward, backward, left, or right.

[0059] Specifically, the aforementioned posture information can be acquired through a posture recognition sensor (i.e., a three-axis gyroscope), which can be installed at the driver's seat or on the steering wheel. Optionally, the posture information can also be acquired through a pressure detection element (e.g., a pressure sensor). It is understood that different driver postures exert different grip pressures on the steering wheel; therefore, this embodiment of the invention can also acquire the posture information through a pressure detection element. Specifically, the pressure detection element can be directly installed on the steering wheel; multiple elements can be installed, or only one can be installed. It can be installed at the left-hand grip position and the right-hand grip position of the steering wheel, and can be configured according to actual needs. This embodiment of the invention does not impose any limitations on this.

[0060] The aforementioned physiological states characterize the driver's health status and can be obtained through the driver's physiological signals. Specifically, these physiological signals may include electrocardiogram (ECG), blood pressure, heart rate, and body temperature. Correspondingly, these physiological signals can be acquired using bioelectrical signal sensors. For example, an ECG sensor can be used to acquire ECG and heart rate, an infrared temperature sensor can be used to acquire the driver's body temperature, and a blood pressure sensor can be used to acquire the driver's blood pressure. Optionally, the aforementioned bioelectrical signal sensors can be mounted on the steering wheel, thereby acquiring physiological signals through driver hand contact.

[0061] Furthermore, after obtaining physiological signals, the driver's current health status can be detected through these signals. For example, an excessively high or low heart rate indicates an abnormal heart rate. Abnormal fluctuations in the electrocardiogram indicate an irregular heart rate. Similarly, excessively high or low body temperature suggests a possible fever or hypothermia. Based on this, embodiments of the present invention can acquire the driver's physiological status through physiological signals.

[0062] Furthermore, after obtaining posture information and physiological state, embodiments of the present invention can control the position and posture of the vehicle's steering wheel based on the posture information to improve driver comfort. For example, if the posture information indicates the driver is forward, embodiments of the present invention can move the steering wheel forward and simultaneously adjust the steering wheel angle upward to avoid the driver being too close to the steering wheel, while also facilitating driver control of the steering wheel. As another example, if the posture information indicates the driver is backward, embodiments of the present invention can move the steering wheel backward and simultaneously adjust the steering wheel angle downward.

[0063] Furthermore, the aforementioned feedback signal can be an electrical signal carrying string information, or it can be a switching signal. Accordingly, the operation of the aforementioned output feedback signal can be to output the string information to a display screen for display, or it can be to output the switching signal to a vibration element, so as to provide feedback to the driver on the monitored physiological state through the vibration operation of the vibration element.

[0064] Specifically, the operation of controlling the position and posture of the steering wheel can be achieved by sending a drive signal to the drive motor of the steering wheel. Different vehicles may have different steering wheel drive methods, so they can be set according to actual needs. This embodiment of the invention does not limit this.

[0065] Optionally, steps 101 to 103 above can be executed according to a preset cycle, or they can be executed under preset execution conditions. In order to ensure the accuracy and real-time performance of steering wheel control, steps 101 to 103 above can also be executed in real time. This embodiment of the invention does not limit this.

[0066] In summary, this embodiment of the invention acquires the driver's posture information and physiological state; controls the steering wheel position based on the posture information; and generates and outputs a feedback signal based on the physiological state. This allows for steering wheel position control based on the driver's posture information, eliminating the need for manual control and improving steering wheel efficiency, thus reducing safety hazards to some extent. Furthermore, automatic adjustment of the steering wheel position based on the driver's posture information enhances the driving experience and comfort. Additionally, acquiring and generating feedback signals based on the driver's physiological state allows for timely monitoring of the driver's physiological condition during driving, providing timely health feedback and further reducing safety hazards and the risk of traffic accidents caused by driver health issues.

[0067] Optionally, the operation of obtaining the driver's posture information of the vehicle described above may specifically include, in this embodiment of the invention:

[0068] S21. Based on the pressure detection element installed on the steering wheel of the vehicle, obtain the grip pressure at each grip position of the steering wheel.

[0069] S22. Based on the gripping pressure at each gripping position and the corresponding reference pressure range for each gripping position, determine the driver's posture information.

[0070] The aforementioned pressure detection element can be a pressure sensor, which can detect the sensed pressure. In this embodiment of the invention, a pressure sensor can be installed at the grip position of the vehicle's steering wheel to detect the grip pressure applied by the driver. Specifically, this embodiment of the invention can receive the detection signal from the pressure detection element through hardware or software, and obtain the grip pressure based on the detection signal. It is understood that different driver seating positions result in different grip pressures on the steering wheel. For example, when the driver's seating position is forward, the grip pressure on the steering wheel is greater; correspondingly, when the driver's seating position is backward, the grip pressure on the steering wheel is less. As another example, when the driver's seating position is to the left, the grip pressure on the left side of the steering wheel is greater than the grip pressure on the right side; correspondingly, when the driver's seating position is to the right, the grip pressure on the right side of the steering wheel is greater than the grip pressure on the left side.

[0071] The aforementioned reference pressure range can be obtained through pre-calibration by the driver. Specifically, during the calibration process, the driver's grip pressure on the steering wheel at various grip positions in a comfortable posture can be obtained first. A certain error range is then set based on the calibrated grip pressure to obtain the reference pressure range corresponding to each grip position. The comfortable posture can be pre-set by the driver, and the steering wheel position in a comfortable posture provides higher driver comfort.

[0072] Specifically, the aforementioned pressure detection elements can be directly installed on the vehicle's steering wheel. Multiple elements can be installed, or only one can be installed. They can be installed at the left-hand and right-hand grip positions, respectively, and can be configured according to actual needs. This embodiment of the invention does not impose any limitations on this. Furthermore, this embodiment of the invention can determine the driver's posture information based on the grip pressure at each grip position and a reference pressure range. Specifically, if the grip pressure at each grip position is greater than the maximum value of the reference pressure range, the driver's posture information can be determined to be forward. Correspondingly, if the grip pressure at each grip position is less than the minimum value of the reference pressure range, the driver's posture information can be determined to be backward. Further, if the grip pressure at the left grip position is greater than the grip pressure at the right grip position, the driver's posture information can be further determined to be left-hand.

[0073] In this embodiment of the invention, a pressure detection element installed on the steering wheel of the vehicle is used to acquire the grip pressure at each gripping position of the steering wheel. Based on the grip pressure at each gripping position and the corresponding reference pressure range for each gripping position, the driver's posture information is determined. Thus, by setting a pressure sensor in the steering wheel, the driver's posture information can be acquired in a timely manner, facilitating automatic adjustment of the steering wheel's position based on this posture information. This reduces driver fatigue and improves driving comfort and convenience. It eliminates the need for manual control of the steering wheel's position by the driver, improving steering wheel control efficiency and reducing safety hazards to some extent. Simultaneously, automatic adjustment of the steering wheel's position based on the driver's posture information enhances the driver's driving experience and improves driving comfort.

[0074] Optionally, the aforementioned attitude information includes at least longitudinal attitude information, and the operation of controlling the steering wheel pose of the vehicle based on the attitude information may specifically include:

[0075] S31. Based on the longitudinal posture information, adjust the longitudinal position and angle of the vehicle's steering wheel.

[0076] The aforementioned longitudinal posture information refers to the driver's posture in the vehicle's forward direction, which can be forward or backward. Accordingly, embodiments of the present invention can adjust the longitudinal position and angle of the vehicle's steering wheel based on the longitudinal posture information.

[0077] Specifically, during the adjustment of the longitudinal position, adjustments can be made according to a preset distance. That is, the preset distance is adjusted each time, and then the operation of step 101 above can be repeated to obtain new longitudinal attitude information. If further adjustments are needed, the preset distance is adjusted again. Furthermore, the direction of adjustment of the longitudinal position can be determined based on the distance between the driver and the steering wheel represented by the longitudinal attitude information. When the distance is large, the steering wheel can be adjusted towards the driver; correspondingly, when the distance is small, the steering wheel can be adjusted away from the driver.

[0078] For example, when the posture information indicates that the driver is forward, this embodiment of the invention can move the steering wheel forward and simultaneously adjust the steering wheel angle upward to prevent the distance between the driver and the steering wheel from being too close, while also facilitating the driver's control of the steering wheel. As another example, when the posture information indicates that the driver is backward, this embodiment of the invention can move the steering wheel backward and simultaneously adjust the steering wheel angle downward to prevent the distance between the driver and the steering wheel from being too far, while also facilitating the driver's control of the steering wheel.

[0079] In this embodiment of the invention, the posture information includes at least longitudinal posture information. Based on the longitudinal posture information, the longitudinal position and angle of the vehicle's steering wheel are adjusted. This allows the steering wheel angle and longitudinal position to be automatically adjusted according to the driver's current needs, maintaining optimal comfort for the driver and reducing driver fatigue to some extent.

[0080] Optionally, the aforementioned posture information may further include lateral posture information. Based on this, embodiments of the present invention can also adjust the lateral position of the steering wheel according to the lateral posture information. Alternatively, a prompt message can be generated based on the lateral posture information to indicate whether there is a lateral deviation in the driver's current posture, thereby prompting the driver to adjust the current posture. For example, if the driver's current posture is to the left, the driver can be prompted by a vibration element on the left side of the steering wheel; correspondingly, if the driver's current posture is to the right, the driver can be prompted by a vibration element on the right side of the steering wheel. Alternatively, the driver can also be prompted by seat vibration. As another example, the driver can also be prompted by a vehicle display screen or a head-up display (HUD) system to adjust their posture to a comfortable position in a timely manner based on the prompt message.

[0081] Optionally, the operation of obtaining the driver's physiological state described above may specifically include, in this embodiment of the invention:

[0082] S41. Based on the physiological signal sensor installed on the steering wheel of the vehicle, acquire the driver's electrocardiogram signal and body temperature signal.

[0083] S42. Based on the electrocardiogram signal and the reference electrocardiogram signal, a first physiological state is generated.

[0084] And, S43, based on the body temperature signal and a reference body temperature range, a second physiological state is generated.

[0085] Among them, the aforementioned physiological signal sensors can be ECG sensors and infrared temperature sensors. Specifically, the ECG sensor can detect the driver's electrocardiogram signal, and the infrared temperature sensor can generate the driver's body temperature signal.

[0086] Specifically, the aforementioned ECG sensor can be positioned on the inside of the steering wheel grip area, facilitating contact between the ECG sensor and the driver's fingers. The ECG sensor generates an electrocardiogram (ECG) by contacting human skin. Furthermore, an infrared temperature sensor can also be positioned at the steering wheel grip area, facilitating contact with the driver's palm. This infrared temperature sensor can detect the temperature of the driver's palm, thereby obtaining the driver's body temperature signal.

[0087] Furthermore, embodiments of the present invention can generate the driver's physiological state based on electrocardiogram signals and body temperature signals.

[0088] The aforementioned reference electrocardiogram (ECG) signal can be pre-set. In this embodiment of the invention, a database for studying arrhythmias (MIT-BIH) can be pre-integrated. MIT-BIH includes ECG signals under different health conditions (e.g., abnormal heart rate, arrhythmia, myocardial infarction, etc.). The reference ECG signal can then be obtained from the MIT-BIH database. This embodiment of the invention can then compare the driver's ECG signal with the reference ECG signal and generate a first physiological state characterizing the driver's heart rate based on the comparison result. Specifically, if the driver's ECG signal matches the ECG signal of an abnormal heart rate, the first physiological state can be generated as an abnormal heart rate. Correspondingly, if the driver's ECG signal matches the ECG signal of a myocardial infarction, the first physiological state can be generated as a myocardial infarction. Further, if the driver's ECG signal matches the ECG signal of a healthy heart rate, the first physiological state can be generated as a normal heart rate.

[0089] The aforementioned reference body temperature range can also be preset. Specifically, since normal human body temperature is typically between 35°C and 37°C, the reference body temperature range can be 35°C to 37°C. Based on the driver's body temperature signal and the reference body temperature range, a second physiological state characterizing the driver's body temperature status can be generated. If the body temperature signal falls within the reference body temperature range, the second physiological state can be normal body temperature. If the body temperature signal is less than the minimum value of the reference body temperature range, the second physiological state can be hypothermia. Correspondingly, if the body temperature signal exceeds the maximum value of the reference body temperature range, the second physiological state can be fever.

[0090] In this embodiment of the invention, an electrocardiogram (ECG) signal and body temperature signal of the driver are acquired based on a physiological signal sensor installed on the steering wheel of the vehicle; a first physiological state is generated based on the ECG signal and a reference ECG signal; and a second physiological state is generated based on the body temperature signal and a reference body temperature range. In this way, the driver's ECG and body temperature can be monitored in a timely manner through the physiological signal sensor, and the driver's physiological state can be generated based on the monitored ECG and body temperature signals, allowing for timely and accurate acquisition of the driver's health status. The bioelectrical signal sensor enables real-time monitoring of the driver's heart rate and body temperature physiological indicators through the steering wheel. This allows the driver to understand their own health status at any time, providing timely health feedback to the driver, further reducing safety hazards and the risk of traffic accidents caused by driver health problems.

[0091] Optionally, the operation of generating feedback signals based on the physiological state described above may specifically include, in embodiments of the present invention:

[0092] S51. If the first physiological state does not meet the first preset requirement, and / or if the second physiological state does not meet the second preset requirement, generate a feedback signal based on the first physiological state and / or the second physiological state.

[0093] The first preset requirement can be that the first physiological state is a normal heart rate, and correspondingly, the second preset requirement can be that the second physiological state is a normal body temperature.

[0094] Furthermore, if the first physiological state does not meet the first preset requirement, it indicates that the driver has a heart rate problem, possibly due to abnormal heart rate, arrhythmia, myocardial infarction, or other health issues. In this case, a feedback signal can be generated based on the first physiological state. Correspondingly, if the second physiological state does not meet the second preset requirement, it indicates that the driver has an abnormal body temperature, possibly due to hypothermia or fever. In this case, a feedback signal can be generated based on the second physiological state.

[0095] Furthermore, the aforementioned feedback signal can be a signal carrying string information or a switching signal, which can be set independently based on the vehicle's hardware facilities. This embodiment of the invention does not impose any restrictions on this.

[0096] Optionally, in cases where the driver has an abnormal body temperature, this embodiment of the invention can adjust the steering wheel temperature after generating a feedback signal. Specifically, if the driver has a fever, this embodiment of the invention can lower the steering wheel temperature; conversely, if the driver suffers from hypothermia, this embodiment of the invention can heat the steering wheel to increase its temperature.

[0097] In this embodiment of the invention, when the first physiological state does not meet the first preset requirement, and / or when the second physiological state does not meet the second preset requirement, a feedback signal is generated based on the first physiological state and / or the second physiological state. This allows for timely feedback on the driver's abnormal physiological state, providing early warnings when abnormalities occur in the driver's physical condition, thereby reducing the risk of traffic accidents caused by driver health problems and improving driving safety.

[0098] Optionally, embodiments of the present invention may further include:

[0099] S61. In response to the driver's interactive operation on the interactive element installed on the steering wheel of the vehicle, perform a vehicle control operation matching the interactive operation.

[0100] The interactive elements mentioned above can be buttons, knobs, etc., and the interactive operations can be pressing, rotating, touching, etc. The vehicle control operations can be volume adjustment, making and receiving phone calls, autonomous driving, etc., and can be set according to the actual situation of the vehicle. This embodiment of the invention does not impose any limitations on this. Furthermore, the number of the interactive elements can be one or more, and different interactive operations and different interactive elements can correspond to different vehicle control operations. It can be set according to the actual needs of the vehicle, and this embodiment of the invention does not impose any limitations on this.

[0101] For example, the rotation operation of the interactive element can correspond to the volume adjustment operation, the pressing operation can correspond to the answering and making phone calls, and the touch operation can correspond to the automatic driving operation. These can be set according to actual needs, and the embodiments of the present invention do not impose any restrictions on this.

[0102] This allows for human-machine interface design by incorporating interactive elements within the steering wheel. Drivers can control vehicle functions in multiple ways using only the steering wheel, without needing to operate other devices or buttons, thus improving convenience and efficiency during driving. This enables drivers to focus more on road and traffic conditions, further enhancing driving safety.

[0103] Optionally, correspondingly, the operation of outputting the feedback signal described above may specifically include, in embodiments of the present invention:

[0104] S71. The feedback signal is output to a vibration element installed on the steering wheel of the vehicle; the vibration element vibrates upon receiving the feedback signal.

[0105] The aforementioned vibration element can be a vibration motor, which vibrates upon receiving a feedback signal. This vibration element can be integrated into the steering wheel, allowing the driver to receive feedback while driving. In cases of abnormal driver physiological conditions, the vibration element can alert the driver, prompting them to stop, rest, or call for assistance, further reducing safety hazards.

[0106] In this embodiment of the invention, by acquiring the driver's physiological state and generating a feedback signal based on the physiological state and outputting it to the vibration element, the driver's physiological state can be monitored in a timely manner during driving. The vibration element can provide the driver with timely health feedback, further reducing safety hazards and the risk of traffic accidents caused by driver health problems.

[0107] Optionally, embodiments of the present invention can also detect lane departure by using a lane detection system and detect driver fatigue by using visual recognition technology. Accordingly, in the event of lane departure or driver fatigue, a feedback signal can be output to the vibration element to promptly remind the driver to pay attention to driving safety.

[0108] Optionally, after outputting a feedback signal to the vibration element, the embodiments of the present invention can also enable the driver to call for rescue through the vehicle call system to avoid accidents.

[0109] Optionally, the vehicle's steering wheel may also include touch buttons and pressure sensors, allowing the driver to perform various operations such as adjusting volume, making and receiving phone calls, or using autonomous driving by touching the buttons or pressing designated areas on the steering wheel while driving. This improves convenience and safety during driving.

[0110] It's worth noting that the steering wheel is the object a driver interacts with most during driving. Traditional steering wheels primarily focus on driving operations, only controlling the vehicle's direction. Later, with advancements in automotive technology, steering wheels integrated various functions, such as button controls, scroll wheel controls, and touchscreen controls. During long drives, drivers often change their steering wheel grip due to fatigue or driving habits, requiring manual adjustment of the steering wheel position in some situations to ensure driving comfort.

[0111] In this embodiment of the invention, by integrating various sensors with different functions into the steering wheel or vehicle, the driver's posture and physiological data can be monitored in real time. The monitored posture and physiological data are used to determine the driver's current posture and health status, and then the steering wheel angle and longitudinal position can be adjusted based on the current posture to achieve a personalized and comfortable driving experience. This automatic adjustment function greatly improves driving comfort and convenience, and provides timely health feedback to the driver, reducing the occurrence of accidents. Controlling the vehicle's steering wheel position based on the driver's posture information eliminates the need for manual control, improving steering wheel control efficiency and reducing safety hazards to some extent. Simultaneously, automatically adjusting the steering wheel position based on the driver's posture information enhances the driving experience and improves driving comfort. Furthermore, by acquiring the driver's physiological state and generating and outputting feedback signals based on that state, the driver's physiological state can be monitored in real time during driving, providing timely health feedback and further reducing safety hazards and the risk of traffic accidents caused by driver health problems.

[0112] Optionally, the aforementioned posture information may also include the driver's head posture information, which can be obtained through a posture sensor at the headrest. In this embodiment of the invention, the headrest can also be adjusted based on the head posture information to further improve the driver's comfort and convenience during driving.

[0113] Optionally, embodiments of the present invention can be applied to in-vehicle systems, servers, or the cloud. Accordingly, to ensure data security and privacy, embodiments of the present invention can employ encryption protocols to achieve encrypted transmission and storage of data when acquiring data detected by sensors, thereby preventing the leakage and misuse of user privacy data. Optionally, to ensure stable operation of the steering wheel, embodiments of the present invention can use high-performance materials such as those resistant to high temperatures and corrosion. Simultaneously, embodiments of the present invention can also employ an embedded real-time operating system (RTOS) to ensure the stable operation and fault tolerance capabilities of the steering wheel control method.

[0114] Furthermore, embodiments of the present invention can also optimize the steering wheel control method through software updates or add new functions to the vehicle, thereby further improving the user's driving experience.
