[0023] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0024] Figure 1An interactive control system based on a vehicle steering wheel is provided in this application embodiment. The system includes: a fingerprint recognition module 101, a pressure sensing module 102, and a motor module 103 disposed on the steering wheel; and a control module 104; wherein, The control module 104 is configured to: respond to the fingerprint information corresponding to the first touch operation collected by the fingerprint recognition module 101, recognize the fingerprint information, and obtain a fingerprint recognition result; if the fingerprint recognition result is successful, generate a corresponding pressing signal based on the pressing information corresponding to the first touch operation collected by the pressure sensing module 102; and determine a control signal based on the pressing signal; wherein the control signal includes a vibration control signal and an execution control signal, the vibration control signal is used to control the motor module 103 to vibrate, and the execution control signal is used to control the vehicle to perform corresponding control processing.

[0025] Optionally, the control module 104 may not be located on the steering wheel, such as when the control module 104 is an ECU (electronic control unit for automobiles).

[0026] This application provides an interactive control system based on a vehicle steering wheel. The control module first collects fingerprint information corresponding to a first touch operation through a fingerprint recognition module and identifies the fingerprint information to obtain a fingerprint recognition result. When the fingerprint recognition result is confirmed to be successful, the control module generates a corresponding pressing signal based on the pressing information corresponding to the first touch operation collected through a pressure sensing module. The control module determines a control signal based on the pressing signal. This control signal includes a vibration control signal and an execution control signal. The vibration control signal is used to control the motor module to vibrate, and the execution control signal is used to control the vehicle to perform corresponding control processing. Thus, through the cooperation between the control module, the fingerprint recognition module, the pressure sensing module, and the motor module, a tactile interaction with the steering wheel without visual dependence is realized, improving blind operation safety and ensuring driving safety.

[0027] The steering wheel will be described in detail below.

[0028] In this embodiment, the steering wheel is divided into multiple different position areas, and each position area is equipped with a corresponding fingerprint recognition module, pressure sensing module, and motor module.

[0029] The control module 104 in this embodiment can identify the pressing signal from a corresponding location area among multiple location areas. For ease of description, the target location area is used as an example.

[0030] In one example, the control module 104 is specifically used to: in response to receiving a pressing signal, determine the target location area where the pressure sensing module that sent the pressing signal is located, and determine the corresponding control signal; The vibration control signal in the control signal controls the motor module set in the target location area to vibrate, and the execution control signal in the control signal controls the vehicle to perform corresponding control processes.

[0031] In this example, a mapping relationship can be pre-established between the fingerprint recognition module, pressure sensing module, and motor module in multiple location areas and the identifiers of those location areas. This could be represented by a number corresponding to the identifier of the target location area, such as fingerprint recognition module A (as the number), pressure sensing module A, and motor module A. After establishing the mapping relationship, the control module 104 can control the motor module associated with the target location area to vibrate according to the corresponding vibration control signal.

[0032] In practical use, the aforementioned multiple different position areas can be set according to vehicle model, occupant usage habits, steering wheel position, driving safety indicators, etc. For example, the multiple different position areas include a first connecting area between the first hand-held area and the center area of ​​the steering wheel, and a second connecting area between the second hand-held area and the center area; wherein, the hand-held area can be the area where the occupant's hands grip the steering wheel, which is generally the core area of ​​direct contact during driving; the center area can be the area where the geometric center of the steering wheel is located.

[0033] Optionally, the two fingerprint recognition modules are respectively located in the first handheld area and the second handheld area (e.g., Figure 2 11 and 12 in the middle); the first connection region and the second connection region (such as 11 and 12 in the middle); Figure 2 Pressure sensing modules are respectively set in 13 and 14; the first connection area and the central area (such as Figure 2 A motor module is built into the connection point of section 15), and a motor module is built into the connection point between the second connection area and the central area. The central area is... Figure 2 15.

[0034] exist Figure 2 and Figure 3 In the center, fingerprint recognition modules (such as full-screen fingerprint recognition and flexible fingerprint recognition modules) are arranged in the hand-held areas 11 and 12 of the steering wheel to the connecting areas 13 and 14. A pressure sensing module (such as...) is covered below the fingerprint recognition modules in the connecting areas 13 and 14. Figure 3 (22 is located below 21), and the signal is transmitted to the ECU via the CAN bus.

[0035] exist Figure 2 Linear motor modules are built into the left and right sides of the center area 15 of the steering wheel, corresponding to the center areas 13 and 14. The motors are located below the pressure sensing module. Figure 3 Position 23. Through pressure signals, light pressure (1N) triggers a short vibration, and heavy pressure (3N) triggers a "click" feedback. Vibration is selective based on the fingerprint recognition location: Press. Figure 2 When pressing the left side sections 11 and 13, the left motor vibrates. Figure 2 When the right side of the motor vibrates in areas 12 and 14 on the right side, the motor on the right side vibrates.

[0036] The fingerprint recognition module 101 will be described in detail below.

[0037] The fingerprint recognition module 101 in this embodiment is mainly used to collect fingerprint information corresponding to the first touch operation.

[0038] Here, the first touch operation refers to the operation of the vehicle occupant on the steering wheel, such as the operation on at least one of the multiple position areas on the steering wheel, such as a light touch operation, a light press operation, a hard press operation, etc. on the first connecting area.

[0039] It should be noted that the first touch operation corresponds to different functional services in different vehicle functional scenarios; for example, in the identity function scenario, the touch operation corresponds to the identity authentication service; in the in-vehicle cabin device operating parameter adjustment function scenario, the touch operation corresponds to the air conditioning temperature adjustment service.

[0040] In one example, the fingerprint recognition module may include various types of fingerprint sensors.

[0041] After the fingerprint recognition module 101 collects the fingerprint information corresponding to the first touch operation, the control module 104 recognizes the fingerprint information and obtains the fingerprint recognition result.

[0042] In one example, the method for identifying fingerprint information may include: identifying fingerprint information using a multimodal fingerprint recognition algorithm or a capacitive fingerprint recognition algorithm to obtain a fingerprint recognition result.

[0043] Optionally, the fingerprint recognition result includes both fingerprint recognition failure and fingerprint recognition success. When the fingerprint recognition result is fingerprint recognition failure, the control module is also used to control the motor module to vibrate, so as to prompt the occupants of the vehicle to re-enter the first touch operation.

[0044] Information can be conveyed to the occupants of the vehicle through motor vibration combined with other feedback methods (such as visual and auditory cues).

[0045] By combining vibrations of different frequencies, intensities, and durations, a "recognition failure" signal is encoded to avoid confusion with normal operations (such as power steering feedback). For example: Short, high-frequency vibrations: 3 times in a row, each lasting 0.2 seconds, with an interval of 0.1 seconds.

[0046] Gradually increasing vibration: from weak to strong for 1 second, then suddenly stops.

[0047] Directional vibration: If the steering wheel has a built-in multi-zone motor (such as left and right zones), the left motor can vibrate twice and the right motor can vibrate once to provide directional feedback.

[0048] The pressure sensing module 102 will be described in detail below.

[0049] In this embodiment, the pressure sensing module 102 mainly collects the pressing information corresponding to the first touch operation.

[0050] Here, the pressure information corresponding to the first touch operation includes the press duration and / or the press pressure. For example, a light touch (corresponding to the first touch operation) has a press pressure of 0.8 N (Newtons) and a press duration of 150 ms (milliseconds); a light press has a press pressure of 2 N and a press duration of 200 ms; and a hard press has a press pressure of 4 N and a press duration of 250 ms.

[0051] In this embodiment of the application, after collecting the press information corresponding to the first touch operation, the press information is compared with the corresponding threshold, and a corresponding press signal is generated based on the comparison result.

[0052] For example, the first threshold includes: a pressure threshold of <1N, and a pressure duration threshold of 150ms. The pressure information for a light touch operation, a press operation, and a hard press operation are compared with the first threshold to determine that a pressure of 0.8N and a pressure duration of 150ms constitute a light touch operation.

[0053] The first threshold includes: the pressure threshold is between 1N and 3N, and the pressure duration threshold is 200ms. The pressure information of light touch operation, press operation, and hard press operation are compared with the second threshold to determine that the pressure of 2N and the pressure duration of 200ms are light touch operation.

[0054] The third threshold includes: the threshold for pressure intensity is: the pressure intensity is greater than 3N, and the threshold for pressing duration is: the pressing duration is equal to 250ms. The pressing information of light touch operation, press operation, and hard press operation are compared with the third threshold respectively to determine that the pressing intensity of 4N and the pressing duration of 250ms are the pressing information of hard press operation.

[0055] It should be noted that the above three thresholds (i.e., the first threshold, the second threshold, and the third threshold) are only examples. The number of thresholds can be set according to the number of corresponding functional services in the functional scenario, such as one threshold for each functional service.

[0056] Furthermore, the range of each threshold can be set according to specific functional scenarios to differentiate between them. For example, in the identity function scenario, the thresholds for light touch operation press information are: press force < 1N, press duration equal to 150ms; the thresholds for light press operation press information are: press force between 1N and 3N, press duration equal to 200ms; and the thresholds for hard press operation press information are: press force greater than 3N, press duration equal to 250ms. In the function scenario of adjusting the working parameters of in-cabin equipment, the thresholds for light touch operation press information are: press force < 1N, press duration greater than 750ms; the thresholds for light press operation press information are: press force between 1N and 3N, press duration greater than 800ms; and the thresholds for hard press operation press information are: press force greater than 3N, press duration greater than 850ms.

[0057] After the pressure sensing module collects the pressing information corresponding to the first touch operation, it transmits this information to the control module. The control module then generates a pressing signal based on the pressing duration and pressure intensity. This can be described as follows: The pressure sensing module collects the pressing information corresponding to the first touch operation; it compares the pressing information with a preset threshold to determine the comparison result; and it generates the corresponding pressing signal based on the comparison result. For example, when a person in the car presses the steering wheel, the thin-film pressure sensor detects the pressing intensity in real time with an accuracy of 0.01N and transmits the pressing information to the control module. The control module classifies the touch operation into three levels—light touch (0-1N), light press (1-3N), and heavy press (>3N)—based on two thresholds, 1N and 3N, and triggers a differentiated feedback mode based on the pressing duration (short press <0.2 seconds, long press >0.8 seconds). For example, when a light press initiates fingerprint recognition, the corresponding linear motor vibrates at a high frequency (200Hz, 0.1 seconds) to indicate recognition is in progress; when a heavy press confirms the function, both motors vibrate at a low frequency (50Hz, 0.3 seconds) to synchronously provide feedback on success, with the vibration intensity dynamically adjusted according to the pressing position (e.g., the left motor intensity increases by 30% when pressing the left area); a long press (>2 seconds) triggers the saving of the environment preset, and the motor guides the operation with gradually increasing vibration (50Hz to 200Hz, 0.5 seconds), while the pressure sensor records the pressing trajectory to prevent accidental touches.

[0058] Optionally, the relationship between the pressure applied and the touch duration can be set as follows: 1. Touch operation, pressure <1N, press duration 200ms; 2. Touch operation, pressure <1N, press duration >800ms; 3. Press lightly, with a pressure between 1N and 3N and a pressing duration of 200ms; 4. Press lightly, with a pressure between 1N and 3N and a pressing duration greater than 800ms; 5. Press hard, with a pressure greater than 3N and a pressing duration of 200ms; 6. Press hard, with a pressing force greater than 3N and a pressing duration greater than 800ms; Each relationship corresponds to a semantic meaning, and can display a variety of configuration effects in different functional scenarios.

[0059] The motor module 103 will be described in detail below.

[0060] The motor module in this embodiment is used to provide touch feedback to people inside the vehicle and is a module that converts electrical energy into mechanical energy.

[0061] In the embodiments of this application, the motor module is generally driven by the control module to vibrate in order to achieve touch feedback. For example, the control module can drive the motor module to vibrate based on the information collected by the fingerprint recognition module and / or the pressure sensing module; for example, the control module can output information (such as fingerprint recognition results or control signals) based on the information collected by the fingerprint recognition module and / or the pressure sensing module. For example, when a person inside the vehicle operates the steering wheel, the fingerprint recognition module collects the fingerprint information corresponding to the first touch operation. At this time, the motor module can provide at least one of the following touch feedbacks in response to the first touch operation: If the control module controls the motor module to vibrate according to the first vibration control signal, it will prompt the people in the vehicle (such as the driver) to operate the steering wheel again, so as to collect the fingerprint information corresponding to the first touch operation through the fingerprint recognition module again. Generally, prompting to operate the steering wheel again is because the fingerprint recognition module has not collected the fingerprint information corresponding to the first touch operation (or the collected fingerprint information is incomplete or incorrect, and fingerprint recognition cannot be performed).

[0062] If the control module controls the motor module to vibrate according to the second vibration control signal, it will prompt the user to confirm that the operation was the first touch operation.

[0063] For example, if the pressure signal generated by the pressure information collected by the pressure sensing module is garbled, the control module will control the motor module to vibrate according to the third vibration control signal; this is generally caused by incorrect pressure information collected by the pressure sensing module.

[0064] If the fingerprint recognition result is a failure, the system will prompt the user to operate the steering wheel again. The control module will then control the motor module to vibrate according to the fourth vibration control signal until the fingerprint recognition result is successful. The number of times the steering wheel can be operated again can usually be set, such as three times.

[0065] If the execution control signal in the control signal is used to control the vehicle to adjust the in-vehicle air conditioning temperature, the motor module can be controlled by the control module to vibrate according to the fifth vibration control signal to prompt the occupants to adjust the in-vehicle air conditioning temperature. At this time, the occupants can operate the steering wheel again to confirm that the in-vehicle air conditioning temperature needs to be adjusted.

[0066] It should be noted that the first vibration control signal, the second vibration control signal, and the third vibration control signal can refer to the vibration frequency, and the fourth vibration control signal and the fifth vibration control signal can refer to vibration according to different vibration intensities and vibration durations.

[0067] In addition, the control module can also control the motor module to vibrate according to the corresponding vibration control signal for the functional services within the functional scene identified by the scene recognition module.

[0068] For example, at least one of the following services, such as identity authentication service, seat position adjustment service, air conditioning temperature adjustment service, and entertainment playback adjustment service, can be controlled by the control module to vibrate the motor module to prompt confirmation of the above service, such as when identity authentication is in progress.

[0069] If at least one of the following services is provided: door open warning, lane departure warning, and blind spot warning, the control module can control the motor module corresponding to the above service to vibrate according to the corresponding vibration control signal; if the left door is not closed, the control module controls the motor module on the left side of the steering wheel to vibrate according to the corresponding vibration control signal to alert the occupants that the left door is not closed; if the vehicle deviates from the lane on the left, the control module controls the motor module on the left side of the steering wheel to vibrate according to the corresponding vibration control signal to alert the occupants that the vehicle has deviated from the lane on the left.

[0070] It should be noted that the above-mentioned vibration control signals are also designed to facilitate differentiation among vehicle occupants. The following principles can be followed when setting these vibration control signals: Uniqueness: Distinguish different functional services, such as identity authentication service (corresponding to successful fingerprint recognition) and door open alarm service.

[0071] Perceptibility: It can still be perceived by people inside the vehicle in driving environments (such as noise and bumps).

[0072] Non-distracting: Avoid excessive vibrations that may distract you (such as prolonged continuous vibrations).

[0073] The interactive control method based on the vehicle steering wheel provided in this application embodiment can control the motor module to vibrate according to the corresponding vibration control signal at any stage of the execution process, so as to transmit information to the people in the vehicle in a timely manner. This solution can not only improve the user experience, but also improve driving safety.

[0074] In addition, the above-mentioned multiple vibration control signals can be used as different vibration modes. When the control module receives information from at least one of the fingerprint recognition module, pressure sensing module and scene recognition module, the control module calls the predefined multiple vibration modes (success, failure, warning, etc.) to control the motor module to vibrate according to the corresponding vibration mode to alert the people in the vehicle.

[0075] Optionally, based on the motor module, information can be conveyed to the occupants of the vehicle by combining other feedback methods (such as visual and auditory cues).

[0076] If the vibration triggers a voice prompt, such as "Fingerprint recognition failed, please check your finger position."

[0077] For example, when the steering wheel backlight flashes in sync with the vibration, it creates a dual "visual-tactile" reminder.

[0078] Optionally, the motor module can be designed as an independently driven dual linear motor module, achieving precise differentiation of hand feedback through hardware-level signal isolation. Simultaneously, a capacitive sensor (i.e., a pressure sensor module) is used to detect the touch location of the occupant. When the occupant presses the steering wheel with one hand, the corresponding motor module responds, while the other remains silent. When both hands operate the steering wheel simultaneously, the two motors work together, differentiating primary and secondary operations through vibration intensity differences (e.g., left motor 70% intensity / right motor 100%). For example, in a game scenario, a light press triggers acceleration; the left motor simulates engine roar with continuous short vibrations (100Hz, 0.2 seconds / time), while the right motor provides intermittent vibrations (50Hz, 0.1 seconds / time) to indicate skill cooldown. When a heavy press activates a skill, both motors enhance the impact with a burst of long vibrations (200Hz, 0.5 seconds). The pressure sensor synchronously detects the difference in pressure applied by both hands; if the difference exceeds 20%, a vibration intensity compensation mechanism is triggered to ensure consistent feedback.

[0079] In some examples of this application, the vehicle steering wheel-based interactive control system further includes: a scene recognition module; and a control module, which is further configured to: determine the functional scene in which the vehicle is located if the fingerprint recognition result is successful; determine the functional service corresponding to the first touch operation in the functional scene; generate a pressing signal corresponding to the functional service based on the pressing information corresponding to the first touch operation collected by the pressure sensing module; wherein, the vibration control signal is used to control the motor module to perform vibrations corresponding to the functional service according to at least one of the following: vibration frequency, vibration intensity, and vibration duration; and the execution control signal is used to control the vehicle to perform control processing corresponding to the functional service.

[0080] Specifically, when the fingerprint recognition result is successful, the current functional scene of the vehicle is determined by the scene recognition module, and the functional service (such as entertainment playback) corresponding to the first touch operation is determined. Then, a control signal is generated according to the press signal corresponding to entertainment playback to control the motor module to vibrate according to at least one of the corresponding vibration frequency, vibration intensity and vibration duration, and to control the vehicle to perform the control processing of entertainment playback.

[0081] In this example, the scene recognition module is used to determine the current functional scene of the vehicle when the fingerprint recognition result is successful, so as to perform targeted control on the vehicle.

[0082] Optionally, in this example, vehicle status parameters (such as interior temperature, door open, seatbelt not fastened, vehicle speed, left side crossing the line, etc.) can be collected, and the corresponding classification model can identify the status parameters to determine the current functional scenario of the vehicle.

[0083] The functional scenarios in this application embodiment are based on the functional services provided by the vehicle to the occupants. The same type of functional service is divided into a functional scenario, such as game service and entertainment playback service as the functional scenario for adjusting the working parameters of the in-cabin equipment.

[0084] In one example, the functional scenarios include at least one of the following: identity function scenario, in-cabin device operating parameter adjustment function scenario, and environmental perception scenario; wherein, the operating parameters include at least one of the following: seat position parameters, air conditioning temperature parameters, and entertainment playback operating parameters; the environmental perception scenarios include at least one of the following: door status perception scenario, lane departure status perception scenario, and blind spot status perception scenario; the functional services include at least one of the following: identity authentication service, seat position adjustment service, air conditioning temperature adjustment service, entertainment playback adjustment service, door open warning service, lane departure warning service, and blind spot warning service.

[0085] The following example uses the identity function scenario.

[0086] When the vehicle is parked, occupants can place their fingers anywhere on the fingerprint recognition area while holding the steering wheel. No pressure is required. The system will automatically collect fingerprint feature points and compare the fingerprint features with the data already entered into the system for identity authentication.

[0087] It should be noted that the above-mentioned cockpit equipment operating parameter adjustment function scenario and environmental perception scenario are based on successful identity recognition (i.e., successful identity authentication).

[0088] For example, after successful identity recognition, the correspondence between the central control menu and the steering wheel can be defined, such as defining touch operation 1 as confirmation, touch operation 2 as return, touch operation 3 as next, touch operation 4 as previous, and touch operation 5 as return to the home page.

[0089] When defining the correspondence between the central control menu and the steering wheel, the relationship between the central control menu and various functional services in the functional scenarios is also customized. For example, touch operation 3 is used to play the next song in the music playback service, and touch operation 4 is used to play the previous song.

[0090] The following example uses the scenario of adjusting the working parameters of the equipment in the cockpit.

[0091] After successful fingerprint recognition, the system can automatically adjust the seat position, air conditioning temperature, and entertainment system (such as volume and play / pause). At the same time, the pressure sensor records the habitual pressing areas of the occupants to optimize subsequent recognition efficiency. If the pressing operation fails, the motor will prompt a retry with intermittent vibration (50Hz, 0.1 seconds / time, 0.2 seconds interval). If it fails 3 times in a row, voice guidance will be activated, forming a multimodal interactive closed loop.

[0092] For example, when a person inside the car presses their finger on the fingerprint recognition area on the steering wheel, the linear motor simulates the tactile sensation of pressing a button. Once the fingerprint is successfully recognized, the vehicle executes the bound function, such as pausing or playing a song. Alternatively, another finger can be used to press and hold the button for a long time to adjust the volume based on the duration of the press, such as a short press for ±1 volume, or a long press for continuous adjustment until the button is released.

[0093] For example, when the car is parked, you can open a music game, press the corresponding finger according to the rhythm to simulate playing an instrument, and enjoy entertainment; open other games and map your fingers to game buttons, such as the brake and accelerator in a racing game.

[0094] The following is a description of the environmental perception service.

[0095] If the functional scenario is an environmental perception scenario, the control module is also used to: if at least one of the following is detected on the side of the target location area, control the motor module located in the target location area to perform a vibration alarm: door open state, lane crossing state, blind spot state; wherein, the target location area is the location area where the pressure sensing module that sends the pressing signal is located.

[0096] Here, the environmental perception scenario mainly targets the perception of the environment inside and outside the vehicle, such as whether the car door is closed, whether the seat belt is fastened, and whether the lane is crossed. Based on the positional relationship between the car door, seat belt, lane, and the vehicle, the corresponding motor module can be driven to vibrate. For example, if the left door is not in a position to vibrate, the left motor module can be driven to vibrate according to the corresponding vibration control signal to alert the occupants that the left door is not closed properly.

[0097] For example, when the vehicle is stationary and engaged in forward / reverse gear, the door closing status is detected when the brake is released. If the left door is not closed, the left motor vibrates to alert the driver, and vice versa. In the lane keeping assist function, the corresponding motor on the left or right side can vibrate based on whether the left or right lane is crossed. In the blind spot radar warning function, the vibration effect of the motors on both sides can be adjusted according to the approach direction and distance. For example, the closer the left side is, the higher the vibration frequency of the left motor, thus enabling the driver to perceive the vehicle's environment from the steering wheel.

[0098] Figure 4 This application provides an embodiment of an interactive control method based on a vehicle steering wheel, which is applied to an interactive control system based on a vehicle steering wheel. For example... Figure 4 As shown, the interactive control method based on the vehicle steering wheel may include the following steps: Step 401: In response to the fingerprint information corresponding to the first touch operation detected by the fingerprint recognition module, the fingerprint information is recognized to obtain the fingerprint recognition result.

[0099] Step 403: If the fingerprint recognition result is successful, the pressure sensing module collects the pressing information corresponding to the first touch operation and generates the corresponding pressing signal.

[0100] Step 405: Determine the control signal based on the pressing signal; wherein, the control signal includes a vibration control signal and an execution control signal, the vibration control signal is used to control the motor module to vibrate, and the execution control signal is used to control the vehicle to perform corresponding control processing.

[0101] The following describes step 401 (i.e., in response to the fingerprint information corresponding to the first touch operation being detected by the fingerprint recognition module, the fingerprint information is recognized to obtain the fingerprint recognition result).

[0102] In step 401, when the fingerprint information corresponding to the first touch operation is collected by the fingerprint recognition module, the control module recognizes the fingerprint information and obtains the fingerprint recognition result.

[0103] In this embodiment, a fingerprint recognition module installed on the steering wheel collects fingerprint information corresponding to the first touch operation of the steering wheel by the person in the vehicle.

[0104] In some examples of this application, the steering wheel is divided into multiple different position areas, each of which is equipped with a corresponding fingerprint recognition module, pressure sensing module, and motor module.

[0105] Optionally, the control module is specifically used for: In response to receiving a press signal, the target location area of ​​the pressure sensing module that sent the press signal is determined, and the corresponding control signal is determined. The vibration control signal in the control signal controls the motor module set in the target location area to vibrate, and the execution control signal in the control signal controls the vehicle to perform corresponding control processes.

[0106] Optionally, the position area includes a first connecting area between the first hand-held area and the center area of ​​the steering wheel, and a second connecting area between the second hand-held area and the center area.

[0107] The following describes step 403 in detail (i.e., if the fingerprint recognition result is successful, then generate the corresponding pressing signal based on the pressing information collected by the pressure sensing module corresponding to the first touch operation).

[0108] In step 403, when the control module determines that the fingerprint recognition result is successful, it collects the pressing information corresponding to the first touch operation through the pressure sensor and generates a pressing signal corresponding to the pressing information.

[0109] In one example, the press information includes press duration and / or press pressure; step 403 specifically includes: acquiring press information corresponding to the first touch operation through the pressure sensing module; comparing the press information corresponding to the first touch operation with a preset threshold to determine the comparison result; and generating a corresponding press signal based on the comparison result.

[0110] In some examples of this application, if the fingerprint recognition result is successful, the vehicle steering wheel-based interactive control method further includes: determining the functional scene in which the vehicle is located through a scene recognition module; determining the functional service corresponding to the first touch operation in the functional scene; generating a pressing signal corresponding to the functional service based on the pressing information corresponding to the first touch operation collected by a pressure sensing module; wherein, the vibration control signal is used to control the motor module to perform vibrations corresponding to the functional service according to at least one of the following: vibration frequency, vibration intensity, and vibration duration; and the execution control signal is used to control the vehicle to perform control processing corresponding to the functional service.

[0111] In one example, this application embodiment can differentiate between different scenarios based on the functions provided by the vehicle to occupants, such as an identity function scenario, a cabin equipment operating parameter adjustment scenario, and an environmental perception scenario. The operating parameters include at least one of the following: seat position parameters, air conditioning temperature parameters, and entertainment playback operating parameters. The environmental perception scenario includes at least one of the following: door status perception scenario, lane departure status perception scenario, and blind spot status perception scenario. The functional services include at least one of the following: identity authentication service, seat position adjustment service, air conditioning temperature adjustment service, entertainment playback adjustment service, door open warning service, lane departure warning service, and blind spot warning service. It should be noted that the above functional scenarios and the functional services within those scenarios are merely examples and can be configured according to the usage habits of the occupants.

[0112] The following describes step 405 (i.e., determining the control signal based on the pressing signal; wherein the control signal includes a vibration control signal and an execution control signal, the vibration control signal being used to control the motor module to vibrate, and the execution control signal being used to control the vehicle to perform the corresponding control processing) in detail.

[0113] In step 405, a corresponding control signal is generated based on the pressing signal. This control signal is used to control the motor module to vibrate according to the vibration control signal, so as to control the vehicle to perform corresponding control processing according to the execution control signal.
