DETAILED DESCRIPTION

[0046] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0047] It should be pointed out that, in the absence of conflict, the embodiments of the present invention and the technical features therein may be combined with each other.

[0048] The steering wheel system according to the embodiment of the present invention mainly includes a steering wheel body and a control module.

[0049] The structure of the steering wheel body can be as follows: Figure 1 As shown, it includes a support structure 1, several sleeves 2 and several adjustable connecting parts 3.

[0050] The supporting structure 1 is used to support the sleeve 2; the sleeve 2 and the adjustable connecting portion 3 are alternately arranged in a ring structure; each end of the adjustable connecting portion 3 is movably connected to the sleeve 2 adjacent to the end.

[0051] By adjusting the relative position of the adjustable connection portion 3 and the sleeves 2, the spacing between adjacent sleeves 2 can be adjusted, thereby adjusting the volume of the steering wheel body. When the adjustable connection portion 3 is in the first position, the adjustable connection portion 3 separates the two sleeves 2 that are movably connected to it, and the spacing between the two adjacent sleeves 2 is at the maximum adjustable spacing, and the steering wheel body is in an extended state. When the adjustable connection portion 3 is in the second position, the two ends of the adjustable connection portion 3 are simultaneously partially or fully retracted, the spacing between the adjacent ends of the two adjacent sleeves 2 is reduced, and the steering wheel body is in a retracted state.

[0052] It should be noted that the second position can be any position where the distance between two adjacent sleeves 2 is less than the maximum adjustable distance and greater than or equal to the minimum adjustable distance, so that the driver can determine the volume of the steering wheel body after contraction according to his own needs.

[0053] Among them, for the steering wheel body, the maximum adjustable spacing refers to the maximum distance that can be adjusted between two adjacent sleeves 2, that is, the maximum space interval allowed between the two. Figure 1 As shown, when the distance between adjacent sleeves 2 is the maximum adjustable distance, the steering wheel body is in the largest extended state; the minimum adjustable distance refers to the minimum distance that can be adjusted between two adjacent sleeves 2, that is, the minimum space allowed between the two. Figure 2 As shown, when the distance between adjacent sleeves 2 is the minimum adjustable distance, the steering wheel body is in a contracted state with the smallest volume, and the dotted line shows the volume of the steering wheel body when it is in an extended state.

[0054] By switching the steering wheel between extended and retracted positions, the volume of the steering wheel can be adjusted based on the driver's preference, enhancing the driving experience. Furthermore, for vehicles equipped with higher-level intelligent driving systems, such as L2+++, L3, L4, or L5, when intelligent driving is enabled, the user can operate the vehicle without the steering wheel. By switching the steering wheel from extended to retracted, the volume of the steering wheel can be reduced, increasing the driver's mobility.

[0055] In an optional embodiment, as Figure 1 and Figure 2 As shown, the support structure 1 includes: a column 11, a plurality of first connecting arms 12 and second connecting arms 13 corresponding to the first connecting arms 12 on a one-to-one basis.

[0056] One end of the column 11 is fixed to the vehicle to secure the steering wheel system in the vehicle. The other end of the column 11 is fixedly connected to a second connecting arm 13. One end of a plurality of second connecting arms 13 is evenly distributed around the other end of the column 11, and the second connecting arms 13 extend radially from the other end of the column 11.

[0057] One end of the above-mentioned first connecting arm 12 is hinged to the other end of the above-mentioned second connecting arm 13 so that the first connecting arm 12 can rotate relative to the second connecting arm 13; the other ends of several of the above-mentioned first connecting arms 12 are hinged to one of the above-mentioned sleeves 2 so that the first connecting arm 12 can rotate relative to the sleeve 2.

[0058] Specifically, in the process of the adjustable connection part 3 switching from the first position to the second position, that is, in the process of the steering wheel body switching from the extended state to the contracted state, the first connecting arm 12 rotates around the other end of the second connecting arm 13 based on the hinged position, so that the angle α between the first connecting arm 12 and the second connecting arm 13 is less than 180°, thereby reducing the volume of the steering wheel body; in the case of the adjustable connection part 3 switching from the second position to the first position, the first connecting arm 12 rotates around the other end of the second connecting arm 13 based on the hinged position, so that the first connecting arm 12 and the second connecting arm 13 are on the same straight line, thereby expanding the volume of the steering wheel body.

[0059] In an optional embodiment, a device for increasing input torque may be further provided in the column 11. After the steering wheel is retracted, the device for increasing input torque may be activated, allowing the driver to input a smaller torque with less force, which is then converted into a larger torque by the device for controlling the rotation of the steering wheel. This facilitates the driver to use the retracted steering wheel in an emergency.

[0060] In an optional embodiment, as Figure 3 As shown, accommodating cavities 21 are provided at both ends of the sleeve 2. The length of the sleeve 2 may be greater than the length of the adjustable connecting portion 3. The length of each accommodating cavity 21 is less than or equal to half the length of the adjustable connecting portion 3, so that half of the adjustable connecting portion 3 can be completely accommodated within the corresponding accommodating cavity 21. By providing the accommodating cavities 21 in the sleeve 2 to accommodate the adjustable connecting portion 3, the steering wheel body can be switched between an extended state and a retracted state by moving the adjustable connecting portion 3 within the accommodating cavities 21.

[0061] During the process of switching the adjustable connection portion 3 from the first position to the second position, several adjustable connection portions 3 can simultaneously move into the receiving cavity 21 of the adjacent sleeve 2. For each adjustable connection portion 3, its two ends are respectively connected to different sleeves 2, and each end moves into the receiving cavity 21 of the sleeve 2 to which it is connected. When the adjustable connection portion 3 is in the second position, both ends of the adjustable connection portion 3 are simultaneously partially or fully accommodated in the receiving cavity 21 of the two sleeves 2 to which it is connected.

[0062] When the steering wheel body is in the smallest contracted state, the adjustable connecting portion 3 can be completely received in the accommodating cavity 21 of the two sleeves 2 it connects, so that the two adjacent sleeves 2 are docked and the distance between them is the minimum adjustable distance.

[0063] In an optional embodiment, the column is further provided with a stepper motor for controlling the movement of the hinges between the first connecting arm 12 and the second connecting arm 13, and the hinges between the first connecting arm 12 and the sleeve 2. By controlling the movement of the two hinges, the stepper motor can precisely adjust the angle between the first connecting arm 12 and the second connecting arm 13, as well as the angle between the first connecting arm 12 and the sleeve 2. When the stepper motor causes the two angles to change, the first connecting arm 12 can drive the sleeve 2 to rotate, thereby changing the relative position between the sleeve 2 and the adjustable connecting portion 3 connected thereto, thereby controlling the length of the adjustable connecting portion 3 within the accommodating cavity 21, thereby adjusting the second position of the adjustable connecting portion 3, and achieving stepless adjustment of the length of the adjustable connecting portion 3 within the accommodating cavity 21, thereby adjusting the volume of the steering wheel body to any state between the extended state (maximum volume) and the contracted state (minimum volume).

[0064] In an optional embodiment, as Figure 1 、 Figure 2 and Figure 4 As shown, the steering wheel body further includes a soft outer cover 4 which is sleeved on the outer side of the sleeve 2 and the adjustable connecting portion 3 , thereby improving the driver's feel for gripping the steering wheel.

[0065] Optionally, the soft cover 4 may be made of rubber material, which has high elasticity and high strength and wear resistance. While meeting the volume change of the steering wheel body, it can also reduce the wear caused by daily use.

[0066] In an optional embodiment, as Figure 4As shown, the steering wheel body further includes an airbag cavity 5 disposed between the sleeve 2 and the soft outer cover 4, and between the adjustable connecting portion 3 and the soft outer cover 4. The airbag cavity 5 provides a certain degree of support for the steering wheel body, and the hardness of the steering wheel body can be adjusted by adjusting the gas content in the airbag cavity 5.

[0067] Optionally, the airbag cavity 5 can be made of rubber material. Since rubber material has high elasticity and high strength and wear resistance, it can meet the changes in gas content in the airbag cavity 5 while reducing wear caused by daily use.

[0068] In an optional embodiment, the steering wheel system may further include a sensor module 6. The sensor module 6 includes a plurality of sensors disposed on the steering wheel body.

[0069] Specifically, if Figure 4 As shown, the sensor module 6 includes an air pressure sensor 61 for detecting the air pressure in the airbag cavity 5 and a touch sensor 62 arranged between the airbag cavity 5 and the sleeve 2; when the air pressure is greater than the air pressure threshold and the touch sensor 62 detects a touch signal, the control module generates a whistle signal.

[0070] The air pressure sensor 61 can be installed at any position within the airbag cavity 5. The touch sensor 62 can also be installed between the airbag cavity 5 and the adjustable connecting portion 3, and arranged around the steering wheel body. This allows touch sensors 62 to be installed between the sleeve 2 and the airbag cavity 5, and between the adjustable connecting portion 3 and the airbag cavity 5. Even when the driver places his hand anywhere on the steering wheel body while turning, the air pressure detected by the air pressure sensor 61 and the touch signal detected by the touch sensor 62 can generate a horn signal, causing the vehicle to sound the horn.

[0071] By setting a sensor module 6 in the steering wheel system and associating it with the horn system, a horn signal is generated by the air pressure detected by the air pressure sensor 61 and the touch signal detected by the touch sensor 62. The horn can be triggered according to the driver's wishes while the driver is holding the steering wheel, which will not affect the driver's operation of the steering wheel. This avoids the problem that the horn trigger device is set in the center of the steering wheel body, and the driver's attention is focused on the road conditions and both hands are operating the steering wheel, so he has no time to operate the horn trigger device in an emergency.

[0072] Alternatively, as Figure 4As shown, the sensor module 6 further includes a physiological parameter sensor 63 disposed on the soft outer jacket 4 for detecting the driver's physiological parameters. The physiological parameter sensor 63 can be disposed on the side of the soft outer jacket 4 facing the driver's palm, so that the driver can detect the driver's physiological parameters through the physiological parameter sensor 63 while operating the steering wheel and upload them to the vehicle control system. The vehicle control system then determines the driver's physical condition based on the analysis of the driver's physiological parameters.

[0073] Among them, physiological parameters may include heart rate, blood pressure, blood oxygen, body temperature, respiratory rate, etc., but are not limited thereto.

[0074] In an optional embodiment, the steering wheel system may further include: a control module.

[0075] The control module is configured to receive a telescopic control signal and control the adjustable connection portion 3 to switch between the first position and the second position according to the telescopic control signal, thereby controlling the extension and contraction of the steering wheel body.

[0076] The telescopic control signal can be manually triggered by the driver or automatically generated by the intelligent driving system in response to the activation of intelligent driving. Specifically, when the driver desires the steering wheel body to increase in volume, the steering wheel control device can trigger a telescopic control signal to instruct the steering wheel body to extend. When the driver desires the steering wheel body to decrease in volume, the steering wheel control device can trigger a telescopic control signal to instruct the steering wheel body to retract. When the intelligent driving system is activated, a telescopic control signal to instruct the steering wheel body to retract can be generated and sent to the control module. When the intelligent driving system is deactivated, a telescopic control signal to instruct the steering wheel body to extend can be generated and sent to the control module. Based on the telescopic control signal, the control module can control the motor, thereby driving the sleeve 2 to move, causing the relative position between the sleeve 2 and the adjustable connecting portion 3 to change, thereby adjusting the length of the adjustable connecting portion 3 within the accommodating cavity 21 to achieve extension and retraction of the steering wheel body.

[0077] In addition, while controlling the relative position change between the sleeve 2 and the adjustable connecting part 3 according to the above-mentioned telescopic control signal, the gas content in the airbag cavity 5 can also be controlled so that the gas content in the airbag cavity 5 increases or decreases as the relative position between the sleeve 2 and the adjustable connecting part 3 changes, that is, in the process of the adjustable connecting part 3 moving from the second position to the first position, the gas content in the airbag cavity 5 increases accordingly, so that the steering wheel body gradually extends; in the process of the adjustable connecting part 3 moving from the first position to the second position, the gas content in the airbag cavity 5 decreases accordingly, so that the steering wheel body gradually contracts.

[0078] By receiving the above-mentioned telescopic control signal through the control module, the volume of the steering wheel can be adjusted according to the driver's wishes so that the volume of the steering wheel body conforms to the driver's usage habits. At the same time, the volume of the steering wheel can also be adjusted according to the smart driving switch to increase the driver's activity space after the smart driving is started.

[0079] In an optional embodiment, the control module uploads the physiological parameters to the vehicle control system, so that the vehicle control system adjusts the parameters of the vehicle's function settings according to the physiological parameters.

[0080] The physiological parameter sensor 63 of the sensor module 6 detects the physiological parameters of the driver, and the control module can summarize the above physiological parameters and send them to the vehicle control system of the vehicle, so that the vehicle control system can analyze the above physiological parameters to determine the driver's physical state, and adjust the parameters of the vehicle's fragrance, air conditioning, seat massage, music, lighting, steering wheel body extension and other function settings according to the driver's physical state to create a car driving environment that matches the driver's current physical state.

[0081] In an optional embodiment, the control module receives an attention prompt signal and controls the expansion and contraction of the airbag cavity 5 according to the attention prompt signal.

[0082] The steering wheel system can be connected to the attention monitoring system through the control module, so that when the attention monitoring system recognizes that the driver is not paying attention during driving, it can generate an attention prompt signal and send it to the control module. The control module can control the increase or decrease of the gas content in the airbag cavity 5 according to the received attention prompt signal, so that the airbag cavity 5 can expand and contract at a certain frequency, thereby prompting the driver to concentrate through the expansion and contraction of the airbag cavity 5.

[0083] According to the steering wheel system of an embodiment of the present invention, by arranging alternately arranged sleeves 2 and adjustable connecting parts 3, and switching the adjustable connecting parts 3 between a first position and a second position, the extension and contraction of the steering wheel body is controlled, and the volume of the steering wheel body is adjusted, so that the volume of the steering wheel can be freely adjusted to suit the driver's operation, and when the steering wheel is not needed, the steering wheel body is contracted to expand the driver's activity space.

[0084] By setting up the sensor module 6, the steering wheel system, the horn system and the vehicle control system are coordinated. The horn is triggered by the sensor set in the steering wheel body and the driver's physiological parameters are detected in real time. The horn can be triggered when the driver operates the steering wheel with both hands, and the vehicle's function settings are adjusted according to the driver's physiological parameters, thereby improving the driver's car experience.

[0085] By linking with the attention system, when it is detected that the driver is not paying attention, the airbag cavity 5 set in the steering wheel body can be adjusted to prompt the driver to concentrate, thereby reducing the probability of traffic accidents and protecting the driver's life and property.

[0086] The vehicle according to the embodiment of the present invention includes the steering wheel system according to any one of the embodiments of the present invention.

[0087] Optionally, the vehicle may further include an intelligent driving system. The intelligent driving system is configured to, in response to intelligent driving being activated, generate an extension / retraction control signal instructing the steering wheel body to retract and transmit the signal to the control module of the steering wheel system so that the control module controls the steering wheel body to retract; and, in response to intelligent driving being deactivated, generate an extension / retraction control signal instructing the steering wheel body to extend and transmit the signal to the control module so that the control module controls the steering wheel body to extend.

[0088] The above-mentioned intelligent driving system can automatically control the vehicle's driving according to the control signal or control instruction indicating intelligent driving without interacting with people or through interacting with external devices or through interacting with the robot driving the vehicle.

[0089] Optionally, the above-mentioned vehicle may also include: a horn system, an attention monitoring system and / or a vehicle control system, etc.

[0090] The horn system may sound the horn according to a driver's trigger command or a horn signal generated by the air pressure detected by the air pressure sensor 61 and the touch signal detected by the touch sensor 62 in the steering wheel system.

[0091] When the attention monitoring system detects that the driver is not paying attention, it can generate an attention prompt signal and send it to the steering wheel system and the vehicle control system. The control module of the steering wheel system can control the airbag chamber 5 to expand and contract according to the above attention prompt signal to prompt the driver to concentrate. At the same time, the vehicle control system can also adjust the parameters of the vehicle's function settings according to the above attention prompt signal, for example, controlling the vibration of the vibration sensor in the seat cushion to prompt the driver to concentrate.

[0092] The vehicle control system can analyze the driver's physiological parameters detected by the physiological parameter sensor 63 in the steering wheel system to determine the driver's physical state and adjust the vehicle's functional settings based on the driver's physical state. Specifically, based on the driver's physiological parameters, the vehicle control system can adjust the vehicle's functional settings using a functional adjustment model.

[0093] The function adjustment model can be generated by obtaining the driver's historical physiological parameters and corresponding historical function setting parameters for a preset historical time period, and using these as a training set to train a big data model. Upon completion of the training, the function adjustment model can be obtained. The big data model can employ, but is not limited to, a neural network, a random forest model, a temporal convolutional network, a reinforcement learning model, and the like.

[0094] In addition, the above-mentioned vehicle may also include a power system, a sensor system, a power supply, etc.

[0095] Among them, the power system may include components that provide power movement for the vehicle. For example, the power system may include an engine, an energy source, a transmission, wheels, tires, etc. Among them, the engine may be an internal combustion engine, an electric motor, an air compression engine, or a combination of other types of engines, such as a hybrid engine consisting of a gasoline engine and an electric motor, or a hybrid engine consisting of an internal combustion engine and an air compression engine. The engine converts the energy source into mechanical energy and provides it to the transmission. Examples of energy sources may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other sources of electricity. The energy source can also provide energy for other systems of the vehicle. In addition, the transmission may include a gearbox, a differential, a drive shaft, a clutch, etc.

[0096] The sensor system may include sensors for sensing the surrounding environment of the vehicle (such as sensors for sensing whether there are targets around, etc.). For example, a positioning system (the positioning system may be a global positioning system (GPS) system, or a BeiDou system or other positioning systems), a radar sensor, an ultrasonic sensor, a laser rangefinder, an inertial measurement unit (IMU), and an image sensor. The positioning system can be used to locate the geographic location of the vehicle. The IMU is used to sense the position and orientation changes of the vehicle based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. The radar sensor may use millimeter wave signals to sense objects in the surrounding environment of the vehicle. In some embodiments, in addition to sensing objects, the radar sensor may also be used to sense the speed and / or direction of travel of the object.

[0097] Image sensors can be used to detect information, objects, people, or human motion inside or outside a vehicle. To detect environmental information, objects, people, or human motion outside the vehicle, image sensors can be placed at appropriate locations outside the vehicle. To detect people or their motion inside the vehicle, image sensors can be placed at appropriate locations inside the vehicle. Image sensors can be either still or video cameras. Furthermore, image sensors can include depth cameras.

[0098] A power source, such as a rechargeable lithium-ion or lead-acid battery, provides power to the various components of the vehicle.

[0099] It will be understood that the composition of the above-mentioned vehicle is merely an example. In actual applications, the above-mentioned vehicle may additionally or alternatively include components other than those shown and described, or some of the components shown above may be reduced, so that components in the above-mentioned modules or systems may be added or deleted according to actual needs.

[0101] By setting up the sensor module 6, the steering wheel system, the horn system and the vehicle control system are coordinated. The horn is triggered by the sensor set in the steering wheel body and the driver's physiological parameters are detected in real time. The horn can be triggered when the driver operates the steering wheel with both hands, and the vehicle's function settings are adjusted according to the driver's physiological parameters, thereby improving the driver's car experience.

[0102] By linking with the attention system, when it is detected that the driver is not paying attention, the airbag cavity 5 set in the steering wheel body can be adjusted to prompt the driver to concentrate, thereby reducing the probability of traffic accidents and protecting the driver's life and property.
