[0002] In the related art, the control of vehicle functions often relies on physical buttons or touchscreens on the in-vehicle center console. The driver needs to shift their attention away from the steering wheel to find and operate the corresponding control buttons, which is not only inconvenient but may also cause the driver to be distracted and increase the risk of traffic accidents.

[0003] However, in the related art, under harsh weather or light conditions, the operation of the traditional center console may be affected. For example, in strong sunlight, the display effect of the touchscreen may be affected, making it difficult for the driver to recognize the interface information; in rainy or snowy weather, wet fingers may cause misoperations; scattered information display: traditional vehicle information displays are often distributed on the instrument panel, center console, and other locations, and the driver needs to switch their line of sight between different locations to obtain the required information, which may cause the line of sight to be scattered and affect driving safety; operation limitations: the traditional physical button and touchscreen operation methods have limitations in terms of function expansion and customization. The number and layout of physical buttons are fixed and cannot be flexibly adjusted according to user needs and the emergence of new functions. Although the center console touchscreen has certain customizability, it is still restricted by the screen size and position, and these problems need to be solved urgently. Summary of the Invention

[0030] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0031] The steering wheel, its control method, vehicle, storage medium, and program product according to embodiments of the present application will be described below with reference to the accompanying drawings. In view of the problem in the related art mentioned in the above background art that the function control mainly depends on the operation of the center console, which may be difficult to operate or misoperated in a bad environment, and the operation keys and operation screens of the center console have relatively high restrictions and cannot meet the various flexible application needs of users, and the information display is also relatively scattered, which is likely to cause the user's line of sight to be distracted, thereby affecting the driving safety of the vehicle. The present application provides a steering wheel for a vehicle, which can be provided with flexible display devices on both sides of the steering wheel rim that can recognize the user's gesture intention and have a visual display effect feedback, so that the user can conveniently operate various functions while maintaining control of the vehicle and can intuitively understand the execution results, communication information, and collaboration information of the vehicle. Thus, the recognition of the user's gestures is realized through the flexible display screen, improving the operation convenience of the driver during driving; various visual effects are used to prompt the driver to take corresponding actions, which helps to improve the driver's recognition and understanding speed of various functions and prompts. The control module controls the vehicle system to execute the control actions corresponding to the user's gesture actions, and controls the flexible display module to display the execution results, and can realize communication and collaborative work with other vehicle systems, providing the driver with richer and more intelligent driving assistance functions, thereby completing the realization of various vehicle control functions through gesture control operations, reducing the user's line of sight transfer, and effectively improving driving safety. Thus, the problems in the related art that the function control mainly depends on the operation of the center console, which may be difficult to operate or misoperated in a bad environment, and the operation keys and operation screens of the center console have relatively high restrictions and cannot meet the various flexible application needs of users, and the information display is also relatively scattered, which is likely to cause the user's line of sight to be distracted, thereby affecting the driving safety of the vehicle, etc. are solved.

[0032] Specifically, Figure 1 is a schematic structural diagram of a steering wheel for a vehicle provided by an embodiment of the present application.

[0033] As Figure 1 shown, the steering wheel of the vehicle includes a steering wheel body 100 and an interaction member 200 flexibly arranged on the steering wheel body 100. Among them, the interaction member 200 includes: a flexible display module 300, a gesture recognition module 400, and a control module 500.

[0034] It can be understood that the flexible arrangement here can be understood as that the interaction member 200 can be bent or plastically deformed to a certain extent according to the actual situation and actual needs, so as to achieve the setting of fitting on the steering wheel body. Among them, the interaction member 200 can be understood here as a flexible display screen including a flexible display module 300 and a gesture recognition module 400 arranged on the steering wheel body 100 and a control module 500. Figure 2 is a schematic diagram of the interaction member framework according to an embodiment of the present application. AsFigure 2 As shown, the interaction component 200 can be implemented by a controller module and a flexible display and touch sensor module. Among them, the flexible display and touch sensor module includes a gesture recognition module 400 and a visual feedback module (flexible display module 300).

[0035] Flexible display module 300

[0036] In some embodiments, the flexible display module 300 can be understood here as a functional module that uses a flexible display screen to display various vehicle information.

[0037] Among them, the flexible display screen in the embodiments of the present application can be made of, but is not limited to, a flexible substrate and flexible electronic components. The material selection includes, but is not limited to, polyimide (PI) substrates and flexible thin-film transistors (TFTs), etc. The display screen is closely attached to the surface of the steering wheel rim through a specific adhesion technique, such as using double-sided tape or a silicone layer, and maintains a predetermined curved shape without generating bubbles or falling off. Among them, the thickness of the display screen can be controlled between 0.2 - 0.5 millimeters to ensure that it does not affect the driver's hand feeling in the steering wheel grip area.

[0038] In addition, the flexible display screen in the embodiments of the present application can adopt, but is not limited to, flexible display technology (such as OLED), so that it has a power consumption level of ≤0.5W to reduce the load on the car battery. The resolution of the display screen is set to 100 - 200 pixels per square centimeter to ensure clarity, and the color depth supports 24 bits to achieve rich color performance. For customization for a specific vehicle model, the size and bending degree of the display screen can be adjusted according to the diameter of the steering wheel, the curvature of the grip area, and the user's preferences. For example, when the diameter of the steering wheel is 38 centimeters, the length of the display screen is set to 9.5 centimeters, the width is 2.5 centimeters, and it adapts to the curvature radius of 19 centimeters, thereby completing the flexible setting in the present application.

[0039] For example, in the embodiments of the present application, the outer sides and the upper surface on both sides of the steering wheel rim can be embedded with a flexible display screen, with a length of approximately one-fourth of the rim. The flexible display screen and the lighting effect module are embedded in the steering wheel rim, making the overall design more compact and harmonious, reducing the space occupied by traditional control buttons, making the interior of the cockpit more concise and spacious, improving the aesthetics of the interior of the cockpit, and facilitating the user's operation with both hands.

[0040] The flexible display module 300 in the embodiments of the present application can display various vehicle information based on the flexible display screen, and can be designed differently according to the actual needs of users or professionals in the field. It has high generalization and practical application capabilities, and effectively improves the user's experience when attached to the steering wheel.

[0041] The gesture recognition module 400 is used to recognize the gesture actions of the user. Among them, the gesture actions include at least one of a sliding action that meets the first preset condition, a click action that meets the second preset condition, a double-click action that meets the third preset condition, and a pinch action that meets the fourth preset condition.

[0042] It can be understood that the first preset condition, the second preset condition, the third preset condition, and the fourth preset condition here refer to some conditions that the sliding action, the click action, the double-click action, and the pinch action need to meet in order to be effectively recognized. For example, the click action needs to have a certain time stay and a certain pressure to avoid misidentifying some accidental touches generated by the user as gesture actions.

[0043] In some other embodiments, the flexible display screen in the present application can recognize the gesture actions of the user and receive information from the user. Among them, the recognizable gesture actions of the user include, but are not limited to, a certain sliding action, a motor action, a double-click action, a pinch action, etc.

[0044] The embodiments of the present application can recognize the gesture actions of the user, so as to recognize the actual intention of the user according to the gesture actions of the user, and thus make a certain reaction. By recognizing the gesture intention, the driver can directly operate the screen during driving, reducing the line-of-sight transfer and improving safety. It effectively improves the human-computer interaction of the present application and the user experience. Moreover, certain conditions can be set for each action to avoid misidentifying the accidental touch actions or other actions of the user as the gesture actions of the user, effectively improving the intelligent level and accuracy of the present application.

[0045] Optionally, in an embodiment of the present application, the gesture recognition module 400 includes: at least one capacitive touch sensor, which is used to detect the contact pressure of the user and determine the gesture action according to the contact pressure.

[0046] Based on the relevant descriptions of other embodiments, it can be understood that the present application can recognize multiple gesture actions of the user. When recognizing multiple gesture actions of the user, the present application can be implemented by at least one capacitive touch sensor provided in the gesture recognition module 400.

[0047] For example, the embodiments of the present application can integrate at least one capacitive touch sensor into the substrate of the flexible display screen, which can detect the contact and pressure changes of the finger, so as to distinguish the gesture actions of the user.

[0048] For example, a swiping action requires a displacement of the continuous contact length between the finger and the flexible display screen ≥ 5 mm; a tapping action requires a contact point with a contact length between the finger and the flexible display screen < 5 mm and a contact duration < 200 ms; a double-tapping action requires the finger to double-tap continuously on the flexible display screen with an interval < 300 ms; a pinching action requires a change in the distance between two contact points on the flexible display screen to reach a reduction or expansion ≥ 2 mm.

[0049] In an embodiment of the present application, at least one capacitive touch sensor can be integrated in the gesture recognition module 400 to detect the contact and pressure changes of the flexible display screen, thereby identifying the user's gesture actions. While the cost and power consumption are relatively low, the high sensitivity of the capacitive touch sensor effectively improves the accuracy of gesture action detection in the present application. Moreover, it can not only detect touch actions but also implement advanced functions such as gesture recognition and multi-touch, providing a more intuitive and rich interaction experience for users.

[0050] Optionally, in an embodiment of the present application, the flexible display module 300 is further configured to generate a visual feedback signal for the communication signal and / or cooperation signal of the target vehicle and feedback the prompt visual feedback signal to the user.

[0051] In some embodiments, when the flexible display module 300 displays vehicle information, it can generate a corresponding visual feedback signal for the communication signal and / or cooperation signal of the target vehicle, and use the flexible display screen to feedback the prompt visual feedback signal to the user. Here, the visual feedback signal can be understood as a signal generated according to the content corresponding to the communication signal, or the content corresponding to the cooperation signal, or the content of both the communication signal and the cooperation signal. Based on this visual feedback signal, the flexible display module 300 can use the flexible display screen to display the content of the communication signal and / or cooperation signal. Here, the target vehicle can be understood as a vehicle equipped with the vehicle steering wheel 10 in the present application.

[0052] Here, the communication signal can be understood as a signal related to vehicle-mounted communication; the cooperation signal can be understood as a signal related to the vehicle-mounted system. For example, relevant update signals sent by the cloud platform and signals of communication terminals connected to the vehicle can be understood as communication signals; vehicle-mounted system fault report signals and vehicle-mounted system request signals can be understood as cooperation signals.

[0053] In an embodiment of the present application, the flexible display module 300 can be used to generate a visual feedback signal for the communication signal and / or cooperation signal of the target vehicle, so as to use the flexible display module 300 to display the visual feedback signal to the user, that is, to display the information content of the communication signal and cooperation signal on the flexible display screen, which helps the user to timely understand the communication situation and vehicle situation, facilitating timely response or adjustment.

[0054] The control module 500 is configured to generate a control action for the target vehicle system corresponding to the gesture action, control the target vehicle system to execute the corresponding control action based on the control action, and control the flexible display module 300 to display the execution result of the control action to the user.

[0055] As a possible implementation, after the gesture recognition module 400 of the embodiment of the present application recognizes the user's gesture action, the control module 500 can collect the user's gesture action and generate a corresponding gesture signal, convert the gesture signal into a corresponding control instruction after processing, and transmit the control instruction to the target vehicle system using the standard I2C communication protocol for further processing to generate a corresponding control action, and then control the target vehicle system to execute the corresponding control action based on the control action. Here, the target vehicle system can be understood as the in-vehicle system that the user wants to control through the gesture action.

[0056] For example, if the user wants to control the closing of the vehicle's high beam, first selects "Light Control" through a click action on the flexible display screen, and then double-clicks "Turn off high beam". After the gesture recognition module 400 recognizes the user's gesture action, it generates a certain gesture signal and sends it to the control module 500. The control module 500 can then collect the gesture signal and generate a control instruction of "Turn off high beam" and send it to the corresponding in-vehicle system. The in-vehicle system receives the control instruction, generates a control action of "Turn off high beam", and controls the high beam to turn off.

[0057] Further, after controlling the high beam to turn off, the control module 500 can also control the flexible display module 300 to display the execution result of the control action to the user. For example, the flexible display module 300 displays feedback prompt information such as "The high beam has been successfully turned off" or "The high beam is not turned on, cannot be turned off" on the flexible display screen.

[0058] In the embodiment of the present application, the control module 500 can generate a corresponding control action for the target vehicle system according to the gesture action, so as to control the target vehicle system to execute the control action and present the result to the user, which greatly facilitates the user's operation, supports multiple gesture recognition functions, and realizes precise control of the flexible display screen.

[0059] Optionally, in an embodiment of the present application, the control module 500 includes: a microprocessing unit, configured to analyze the user's actual intention according to the gesture action and generate a control action according to the actual intention; a vehicle communication interface, configured to receive a cooperation signal and / or a communication signal for feedback to the flexible display module 300; and a display driving unit, configured to feedback the execution result of the control action to the user, and / or feedback a prompt visual feedback signal to the user according to at least one of the communication signal and the cooperation signal.

[0060] During the actual execution process, the control module 500 in this application includes, but is not limited to, a microprocessing unit, a vehicle communication interface, and a display driving unit.

[0061] Among them, the microprocessing unit can analyze the actual intention of the user based on the user's gesture actions and generate corresponding control actions. For example, the microprocessing unit can be, but is not limited to, set as a microprocessor, which is used as the core part of the controller, responsible for receiving the signal input from the gesture recognition module 400, analyzing the user's gesture intention, and converting it into corresponding control instructions. The microprocessor in the embodiments of this application can adopt a high-performance and low-power processor chip, such as the ARM Cortex series, etc.

[0062] The display driving unit can feedback the execution result of the control action to the user, and / or feedback a prompt visual feedback signal to the user according to at least one of the communication signal and the cooperation signal. For example, the display driving unit can feedback the execution result of the control action to the user according to the control instruction output by the microprocessor, or the visual feedback signal of the communication signal, or the visual feedback signal of the cooperation signal, or the visual feedback signal of the execution result and the communication signal, or the visual feedback signal of the execution result and the cooperation signal, or the visual feedback signal of the execution result, the communication signal, and the cooperation signal. Moreover, the display driving unit can control the display effect of the flexible display screen, including, but not limited to, image rendering, animation effects, color changes, etc. The display driving module in the embodiments of this application can be, but is not limited to, a dedicated display driving chip or integrated in the microprocessor.

[0063] For the vehicle communication interface, to achieve communication and collaborative work with other vehicle systems, the control module 500 can be provided with corresponding vehicle communication interfaces, including, but not limited to, a CAN bus interface, a LIN bus interface, etc., to receive the cooperation signal and / or communication signal of the vehicle, such as vehicle speed, navigation information, incoming call information, etc., and feedback them to the flexible display module to achieve various prompting functions.

[0064] In addition, the control module 500 in the embodiments of this application also includes a power management module, a storage module, etc. The power management module is responsible for providing stable and reliable power for the controller and the flexible display screen, including, but not limited to, a DC-DC (direct current - direct current) converter, a linear voltage regulator, etc.; the storage module can provide a certain amount of memory and storage space for the control module to process user gesture signals, cache image data, etc.

[0065] For example, the control module 500 is a controller composed of a group of integrated circuits, and can include the following:

[0066] Microprocessor: Uses an ARM Cortex M3 series chip with a working frequency of 72 MHz, integrating 16 KB of RAM and 128 KB of Flash storage space. The microprocessor receives signals from the gesture recognition module through the ADC interface and sends the parsed instructions to the display driver module through the UART interface.

[0067] Display driver module: Uses a dedicated display driver chip SSD1306 (a single-chip CMOS OLED / PLED driver for OLED dot matrix graphic display systems), supporting the I2C communication protocol. The display driver module is responsible for image rendering according to the control instructions of the microprocessor, supporting a refresh rate ≥ 60 Hz to ensure smooth display effects.

[0068] Vehicle communication interface: Integrated CAN bus controller (such as MCP2515), enabling communication with other vehicle systems (such as ECU), supporting real-time data transmission at a rate of 1 Mbps. The interface is used to receive vehicle status data (such as speed, navigation information) and feedback it to the flexible display screen.

[0069] Power management module: Includes a DC-DC buck converter LM2596, with an input voltage range of 6 - 28 V and an output stable voltage of 3.3 V to provide power required for the microprocessor and display module.

[0070] Memory and storage module: Integrates 16 KB of SRAM for temporary data storage and 128 KB of NOR Flash for firmware and image data storage.

[0071] Embodiments of this application can process multiple functions through multiple functional units of the control module 500, and can communicate and cooperate with other vehicle systems (such as navigation systems, telephone systems, ambient light systems, etc.) based on communication signals and / or cooperation signals, providing richer and more intelligent driving assistance functions for drivers.

[0072] Optionally, in an embodiment of this application, the control module 500 is further configured to match the display type of the execution result according to the gesture action.

[0073] In some embodiments, embodiments of this application can also match different display types according to different gesture actions. Here, the display type can be understood as the visual effect that can be displayed on the flexible display screen.

[0074] For example, when feedbacking and prompting the execution result through the flexible display screen, if the execution is successful, green text prompts and green lights can be matched and displayed; if the execution fails, red text prompts and red lights can be matched and displayed.

[0075] Further, when the flexible display module 300 feeds back a prompt communication signal through the flexible display screen, it can display red fonts and red lights; when feeding back a prompt collaboration signal through the flexible display screen, it can display yellow fonts and yellow lights.

[0076] It should be noted that the specific signals, the different functions and different signals included in the specific signals, and the corresponding display types of the execution results, etc., can all be adjusted by those skilled in the art or users themselves. Here, only an exemplary description is given, without specific limitations.

[0077] In the embodiments of the present application, users can customize the functions and lighting effects of gesture control according to their own operating habits and preferences, increasing the personalized experience. Moreover, the effect feedback can provide intuitive operation feedback for the driver, enhancing the human-machine interaction experience and making the operation more intuitive and efficient.

[0078] Optionally, in an embodiment of the present application, the display types include a gradient color effect feedback display type, a gradient lighting effect feedback display type, a dynamic scrolling effect feedback display type, a flashing border effect feedback display type, and an animation effect feedback display type. Among them, the control module 500 further includes: a speeding prompt unit for controlling the flexible display module 300 of the vehicle to feed back a prompt speeding visual feedback signal to the user; a steering prompt unit for controlling the flexible display module 300 of the vehicle to feed back a prompt steering visual feedback signal to the user; a call prompt unit for controlling the flexible display module 300 of the vehicle to feed back a prompt incoming call visual feedback signal to the user; a lighting adjustment unit for controlling the target vehicle to perform lighting adjustment; and a rearview mirror adjustment unit for controlling the target vehicle to perform rearview mirror adjustment.

[0079] Based on the related descriptions of other embodiments, it can be understood that the present application can match different display types according to the execution results. The display types in the embodiments of the present application include but are not limited to a gradient color effect feedback display type, a gradient lighting effect feedback display type, a dynamic scrolling effect feedback display type, a flashing border effect feedback display type, and an animation effect feedback display type.

[0080] (1) Gradient lighting feedback display type, that is, the gradually brightening and dimming effect: In some function prompts, such as steering prompts and speeding prompts, a dynamic effect of gradually brightening and dimming will appear in the relevant area on the flexible display screen. This effect can quickly attract the driver's attention and remind them to take corresponding actions.

[0081] (2) Gradient color effect feedback display type, i.e., the "color palette" effect: In some functions, such as the ambient light adjustment function, the flexible display screen can display a "color palette" composed of different colors for users to customize the color of the ambient light. For example, when adjusting the color of the ambient light, the user clicks on a specific color in the "color palette" with a finger, and the color of the in-vehicle ambient light changes accordingly.

[0082] (3) Dynamic scrolling effect feedback display type: In some functions, such as the rearview mirror adjustment function, the flexible display screen can achieve a dynamic scrolling effect according to the sliding direction and speed of the user's finger. This helps to provide a more intuitive operation experience and facilitates the user to quickly complete the required adjustments.

[0083] (4) Flashing border effect feedback display type: In some reminder functions, such as the incoming call reminder function, the border on the flexible display screen will show a flashing effect. This effect can quickly attract the driver's attention and remind them that there is a new event to be processed.

[0084] (5) Animation effect feedback display type: The flexible display screen will present corresponding animation effects according to the user's operations. For example, after recognizing the user's gesture, the corresponding operation area will show a short animation effect, such as ripple diffusion, zooming, etc., to indicate the success of the operation.

[0085] By using these visual effects, the flexible display module 300 in the embodiments of the present application can provide an intuitive and vivid user interaction experience, improve the driver's recognition and understanding speed of various functions and reminders during driving, and thus improve driving safety.

[0086] The following takes some specific applications as examples for illustration:

[0087] (1) Overspeed reminder unit: When the vehicle exceeds the set speed threshold, a warning color (such as red or orange, or a gradient from orange to red as the speed increases) appears on the flexible display screens on both sides of the steering wheel, gradually brightening and dimming at a relatively fast frequency until the speed drops below the speed limit and the reminder stops.

[0088] (2) Steering reminder unit: According to the navigation information, the driver is reminded to turn in advance. According to the direction to be turned (left or right), a reminder color (such as green or blue) gradually brightens and dims on the display screen on the corresponding side (left or right) of the steering wheel until the driver turns the wheel in the correct direction according to the navigation information.

[0089] (3) Lighting adjustment unit: When the ambient light adjustment function is activated through specific gestures, a brightness adjustment interface is displayed on the left side of the steering wheel. By sliding a finger up and down on the flexible screen, the brightness can be adjusted. A color selection interface is displayed on the right side of the steering wheel. By sliding a finger, a color can be selected from the color palette interface. While adjusting, the in-vehicle ambient light can be synchronously linked according to the adjusted data.

[0090] (4) Incoming call reminder unit: When the driver receives an incoming call, the flexible display screens on both sides of the steering wheel will prompt the driver with a specific display effect (such as a flashing border). The driver can answer the call by performing a pinch gesture on the flexible display screen, or hang up the call by performing the pinch gesture again during the call. In this way, the driver can conveniently answer and hang up calls during driving, while maintaining control of the vehicle and without being distracted.

[0091] (5) Rearview mirror adjustment unit: Through the flexible display screens on both sides of the steering wheel, the driver can easily adjust the vehicle's rearview mirror. First, the rearview mirror adjustment function is activated through a specific gesture (such as double-tapping), and then the corresponding adjustment interface will be displayed on the flexible display screen. The driver can slide a finger on the screen to adjust the up, down, left, and right directions of the left and right rearview mirrors. During the adjustment process, the rearview mirror will respond to the operation in real time, facilitating the driver to obtain a better view. After the adjustment is completed, the driver can turn off the adjustment function by double-tapping again or other specific gestures. In this way, the driver can easily adjust the rearview mirror during driving, improving driving safety.

[0092] It should be noted that the specific display type definitions and the display type definitions for different functions can be adjusted by those skilled in the art according to the actual situation, and the adaptable functions can also be upgraded through vehicle OTA to obtain more functions. This is only an exemplary illustration here and is not specifically limited.

[0093] The embodiments of this application can use the flexible display screen to achieve various visual effects, such as fading in and out, color change, dynamic scrolling, etc., to prompt the driver to take corresponding actions, which can provide a richer visual experience for the driver, enhance the overall driving pleasure, and help improve the driver's recognition and understanding speed of various functions and prompts, thereby improving driving safety.

[0094] The steering wheel of a vehicle according to an embodiment of the present application can enable a user to conveniently operate various functions and intuitively understand the execution results, communication information, and collaboration information of the vehicle while maintaining control of the vehicle through flexible display devices arranged on both sides of the steering wheel rim that can recognize the user's gesture intentions and provide visual display effect feedback. Thus, the recognition of the user's gestures is achieved through the flexible display screen, improving the operation convenience of the driver during driving; various visual effects are used to prompt the driver to take corresponding actions, which helps to improve the driver's recognition and understanding speed of various functions and prompts. The control module controls the vehicle system to execute the control actions corresponding to the user's gesture actions and controls the flexible display module to display the execution results, and can also achieve communication and collaborative work with other vehicle systems, providing the driver with richer and more intelligent driving assistance functions. Thus, multiple vehicle control functions are completed through gesture control operations, reducing the user's line-of-sight transfer and effectively enhancing driving safety. Therefore, the problems in the related art are solved, where function control mostly relies on the operation of the center console, which may be difficult to operate or misoperated in a bad environment, and the operation keys and operation screens of the center console have relatively high restrictions and cannot meet the various flexible application needs of users. The information display is also relatively scattered, easily causing the user's line of sight to be dispersed, thereby affecting the driving safety of the vehicle, etc.

[0095] Next, a steering wheel control method for a vehicle according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0096] Figure 3 It is a flowchart of the steering wheel control method for a vehicle according to an embodiment of the present application.

[0097] As Figure 3 shown, the steering wheel control method for the vehicle includes the following steps:

[0098] Step S301, receiving the user's gesture action, recognizing the user's actual intention according to the gesture action, and generating a corresponding control action according to the actual intention, where the gesture action includes at least one of a sliding action that meets the first preset condition, a clicking action that meets the second preset condition, a double-clicking action that meets the third preset condition, and a pinching action that meets the fourth preset condition;

[0099] Step S302, controlling the target vehicle system to execute the corresponding control action according to the control action, and feeding back the execution result of the control action to the user, and / or giving a feedback prompt to the user based on at least one of the communication signal and collaboration signal of the target vehicle.

[0100] It should be noted that the foregoing explanations of the embodiments of the steering wheel of the vehicle also apply to the steering wheel control method for the vehicle in this embodiment, and will not be elaborated here.

[0101] The steering wheel control method of a vehicle proposed according to an embodiment of the present application can enable a driver to conveniently operate various functions and intuitively understand the execution results, communication information, and collaboration information of the vehicle while maintaining control of the vehicle through flexible display devices arranged on both sides of the steering wheel rim that can recognize the user's gesture intentions and have visual display effect feedback. Thus, the recognition of user gestures is achieved through a flexible display screen, improving the operation convenience of the driver during driving; various visual effects are used to prompt the driver to take corresponding actions, which helps to improve the recognition and understanding speed of the driver for various functions and prompts; the control module controls the vehicle system to execute control actions corresponding to the user's gesture actions, and controls the flexible display module to display the execution results, and can also achieve communication and collaborative work with other vehicle systems, providing richer and more intelligent driving assistance functions for the driver, thereby completing the realization of multiple vehicle control functions through gesture control operations, reducing the driver's line-of-sight transfer, and effectively enhancing driving safety. Thus, it solves the problems in the related art that function control mostly relies on the operation of the center console, which may be difficult to operate or misoperate in a bad environment, and the operation keys and operation screens of the center console have relatively high restrictions and cannot meet the various flexible application needs of users, and the information display is also relatively scattered, easily causing the driver's line of sight to be dispersed, thus affecting the driving safety of the vehicle, etc.
