DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0019] The following specific examples illustrate the embodiments of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0021] Embodiment 1 Please refer to Figure 1 、 2 An intelligent control system for a steering wheel shown in the figure, including: a cockpit domain controller 10, a hand-off detection module 11, a monitoring camera 12, an audio module 13, a haptic feedback module 14, a dynamic display screen 15, and other functional modules. Among them, the hand-off detection module 11 includes: a pressure sensing unit, a capacitance sensing unit, and a bioelectric signal sensing unit. The pressure sensing unit can detect the holding force of the driver's hand on the steering wheel. The capacitance sensing unit can detect the contact position and area between the driver's hand and the steering wheel. The bioelectric signal sensing unit can detect the physiological state during the process of the driver's hand contacting the steering wheel. At the same time, the monitoring camera 12 can capture video images of the driver's position in real time, for example, focusing on the driver's hand movements to collect image information between the driver's hand and the steering wheel. Therefore, the cockpit domain controller 10 can comprehensively analyze whether the driver has released the steering wheel based on the detection results fed back by the pressure sensing unit, the capacitance sensing unit, and the bioelectric signal sensing unit, and the video images fed back by the monitoring camera 12. For example, the pressure sensing unit can detect that there is a grip force on the steering wheel and the grip force exceeds a preset threshold. The capacitance sensing unit can detect that the correct gripping position on the steering wheel is being contacted and the covered area exceeds a preset threshold. The bioelectric signal sensing unit can detect bioelectric signals, and the monitoring camera 12 can capture the driver's hand placed on the steering wheel. Thus, by integrating data information from multiple dimensions, it is determined that the driver is not currently driving with a released hand, effectively avoiding the influence of the driver's bad driving habits on hand-off detection, such as holding the steering wheel with one hand and the gripping position not meeting the standard, or using other tools to deceive hand-off detection, etc., ensuring the driving safety of the driver.

[0022] It can be seen that in this embodiment, through multi-modal information fusion and comprehensive analysis using advanced machine learning AI algorithms, the accuracy and reliability of hand-off detection can be greatly improved, effectively avoiding misjudgment and missed judgment, and preventing safety accidents caused by the driver releasing the hand.

[0023] It should be noted that the cockpit domain controller 10 can also perform fusion analysis based on the information provided by any multiple of the pressure sensing unit, the capacitance sensing unit, the bioelectric signal sensing unit, and the monitoring camera 12, and there is no limitation in this regard. Of course, comprehensive analysis of information from all dimensions can ensure the accuracy and reliability of hand-off detection. Without departing from the spirit of the present invention, modifications and refinements made by those skilled in the art to the embodiments of the present invention still fall within the scope of the invention application patent of the present invention.

[0024] Furthermore, since the bioelectric signal sensing unit is configured in the hands-off detection module 11, which can detect the driver's bioelectric signals, the cockpit domain controller 10 can thereby perceive the driver's physiological state in real time, such as whether the driver is in a fatigued or unwell state, and issue a reminder when the driver is driving while fatigued to prevent the driver from taking their hands off the steering wheel and ensure the driver's driving safety. In a specific embodiment, when the cockpit domain controller 10 identifies that the driver is driving while fatigued based on the detection results fed back by the bioelectric signal sensing unit, it can correspondingly output a first reminder instruction and send it to the corresponding function module or domain controller. For example, it can control the multimedia function module in the cockpit domain to play music, and can also notify the body domain controller 20 to relieve the driver's fatigue by adjusting the seat adjuster 21 and the massage driver 22. For example, it can adjust the seat posture to maintain the driver's correct driving position, and at the same time, it can also enhance the driver's tactile sensation through seat massage, and so on. It can be understood here that due to the different configurations of different vehicle models, the function modules that can perform corresponding actions when the driver is driving while fatigued are not limited to those described above. For example, it can also be reminded through the corresponding lighting module, etc. If the corresponding function module belongs to the cockpit domain, it can be directly controlled by the cockpit domain controller 10. If the corresponding function module belongs to other domains, the cockpit domain controller 10 will notify the corresponding domain controller to achieve cross-domain control. There are no excessive restrictions on this. Those skilled in the art can still fall within the scope of the invention application patent of the present invention when making modifications and refinements to the embodiments of the present invention without departing from the spirit of the present invention.

[0025] In addition, the audio module 13 can broadcast voice according to the instructions of the cockpit domain controller 10, recognize the driver's voice instructions, and feed them back to the cockpit domain controller 10. The tactile feedback module 14 can sense the driver's touch instructions and feed them back to the cockpit domain controller 10. Correspondingly, the cockpit domain controller 10 can output corresponding execution instructions according to the driver's voice instructions and / or touch instructions and / or gesture actions to control the corresponding function module to act. For example, when the cockpit domain controller 10 recognizes that the driver's voice instruction is "play the next song", it will send a corresponding instruction to the multimedia function module, and after the multimedia function module receives the instruction, it will switch to the next song and play it according to the preset operation process.

[0026] The dynamic display screen 15 can display preset dynamic or static images according to the instructions of the cockpit domain controller 10. For example, since the cockpit domain controller 10 is communicatively connected to the chassis and powertrain domain controller 30, it can correspondingly obtain the power parameter information provided by the chassis and powertrain domain controller 30. In the intelligent driving mode, the dynamic display screen 15 can display some power parameters of the vehicle, such as vehicle speed, battery level, etc. Or the dynamic display screen 15 can also display intelligent driving assistance suggestions or operation guides, etc. Or it can dynamically display relevant information according to the changes in the driving scenario. That is, during navigation, it can display turn prompts, remaining distance to the destination, etc. in real time according to the route plan. During vehicle driving, it can display basic information such as vehicle speed and motor speed in real time, as well as safety prompt information such as lane departure warning and collision warning. There is no excessive limitation on this. Those skilled in the art can still fall within the scope of the invention patent application of the present invention when making modifications and refinements to the embodiments of the present invention without departing from the spirit of the present invention.

[0027] It should also be noted here that since the cockpit domain controller 10 is communicatively connected to the body domain controller 20, it can correspondingly obtain the data information provided by the body domain controller 20. The functional modules included in the body domain include the rain and light sensor module 23, which can monitor information such as the intensity, color, and change frequency of the external ambient light and feedback it to the body domain controller 20. And the body domain controller 20 will provide this information to the cockpit domain controller 10 so that it can automatically adjust the display brightness, contrast, display mode, etc. of the dynamic display screen 15 according to the ambient light intensity. For example, in a strong light environment, when the sun shines directly, the cockpit domain controller 10 will control the dynamic display screen 15 to increase the brightness and optimize the contrast of the displayed content to ensure that the driver can clearly see key information such as navigation instructions, vehicle speed reminders, and lane departure warnings on the dynamic display screen 15. In a low light environment, at night or in a tunnel, the cockpit domain controller 10 will control the dynamic display screen 15 to reduce the brightness and switch to a more concise display mode to avoid glare caused by the over-brightness of the dynamic display screen 15, interfering with the driver's line of sight, thereby improving driving safety and enhancing the comfort and intelligent level of the driving experience.

[0028] It can also be understood that the cockpit domain controller 10 is also communicatively connected to the autonomous driving domain controller 40, and it can correspondingly obtain the intelligent driving state information, vehicle driving state information, and surrounding environment information provided by the autonomous driving domain controller 40. Then the cockpit domain controller 10 can comprehensively analyze by integrating multi-source data information to provide intelligent driving assistance suggestions and operation guides for the driver, improving the driver's vehicle use experience.

[0029] In a specific embodiment, when the cockpit domain controller 10 detects that the driver has released the steering wheel and the vehicle is in the autonomous driving state, to ensure the driver's driving safety, it is necessary to remind the driver to take over manually to avoid safety accidents. For this purpose, the cockpit domain controller 10 outputs a second reminder instruction and sends it to the corresponding functional modules and domain controllers to remind the driver. For example, it controls the steering wheel of the released hand detection module 11 to vibrate, controls the audio module 13 to voice prompt the driver "Please take over the steering wheel", controls the dynamic display screen 15 to display a picture to prompt the driver "Please take over the steering wheel", and notifies the body domain controller to control the atmosphere light strip controller 24 to flash with a light alarm, etc., so as to remind the driver to take over the vehicle in time from multiple sensory dimensions and prohibit driving with the hands off the steering wheel.

[0030] Embodiment 2 Please refer to Figure 2 As shown, this embodiment also provides a vehicle control system, including a cockpit domain controller 10, a body domain controller 20, a chassis and power domain controller 30, an autonomous driving domain controller 40, other domain controllers, etc., as well as functional modules controlled by each domain controller, such as a seat adjuster 21, a massage driver 22, a rain and light sensor module 23, an atmosphere light strip controller 24, etc., and the domain controllers are communicatively connected to each other to provide data information to each other, so as to integrate multi-source data for comprehensive analysis and provide an intelligent vehicle use experience for the driver.

[0031] Based on the above, in the system startup and initialization stage, when the driver enters the vehicle and starts the vehicle power supply, the body controller 20 quickly sends a high-voltage suction control request signal to the chassis and power domain controller 30. After receiving the request, the chassis and power domain controller 30 immediately responds and controls the vehicle's high-voltage battery to start normal output of high-voltage power. On the one hand, it supplies power to the vehicle's high-voltage systems, such as drive motors, high-voltage air conditioners and other equipment, to ensure that the vehicle's power system and key equipment can operate normally. On the other hand, the high-voltage battery continuously charges the low-voltage battery through the battery management system to ensure stable power supply for the low-voltage systems, such as in-vehicle electronic control units, lighting systems, etc. During the vehicle power-on process, each domain controller, such as the cockpit domain controller 10, the body domain controller 20, the chassis and power domain controller 30, the autonomous driving domain controller 40, etc., as well as each functional module and unit simultaneously perform initialization operations, load the corresponding operating programs and configuration parameters, complete hardware self-checks and system initialization settings, and prepare for the subsequent function implementation.

[0032] During vehicle driving, multi-modal information can be collected. For example, driving state information, i.e., the hand-off detection module 11 precisely detects changes in the gripping force of the driver's hand on the steering wheel, identifies the contact position and area between the hand and the steering wheel, monitors the driver's bioelectrical signals, so as to judge whether the driver is in a state that may cause the risk of hand-off, such as fatigue or physical discomfort. And these data are collected in real time and temporarily stored in the cache area inside the hand-off detection module 10. Driver behavior information, i.e., the audio module 13 constantly listens to the voice commands issued by the driver, converts the sound signal into a digital signal and performs preliminary processing. The monitoring camera 12 continuously captures the driver's gesture actions, and identifies the meanings of different gestures through image recognition algorithms. The tactile feedback module 14 collects the tactile feedback demand data generated by the driver's touch operations. And this information is also collected synchronously and transmitted to the cockpit domain controller 10. Environmental information, i.e., the rain and light sensor module 23 continuously monitors information such as the intensity, color, and change frequency of the external ambient light, providing an accurate basis for adjusting the display brightness, contrast, and display mode of the dynamic display screen 15. And the autonomous driving domain controller 40 collects the environmental information around the vehicle through devices such as vehicle-mounted sensors, radars, and cameras, including road conditions, traffic signs, the positions and movement states of other vehicles and pedestrians, etc. At the same time, it obtains the autonomous driving state data of the vehicle itself, such as the current autonomous driving mode, set vehicle speed, navigation path, etc.

[0033] It can be understood that the data collected above will all be fed back to the cockpit domain control 10. For example, the hand-off detection module 11 sends the multi-modal information about the driver's hand state collected through the CAN bus to the cockpit domain control 10. The monitoring camera 12 transmits the processed image information such as the driver's gesture actions and facial expressions to the cockpit domain control 10 using the GMSL2 bus. And the body domain controller 20 and the autonomous driving domain controller 40 respectively send the ambient light data and the autonomous driving state and environmental perception data to the cockpit domain control 10 through their respective corresponding communication buses. Then, the AI large model deployed inside the cockpit domain control 10 performs in-depth fusion and analysis on the received source data. First, preprocess the data from different sensors, remove noise and outliers, and unify the data format. Then, use advanced machine learning algorithms, such as convolutional neural networks in deep learning algorithms for image data processing, and recurrent neural networks and their variants (long short-term memory networks) for voice and time series data processing, to perform fusion analysis on the multi-modal information, so as to accurately identify the driver's intentions, needs, as well as the current driving state and surrounding environmental conditions, and then generate corresponding execution instructions, providing the driver with a safe, comfortable, and intelligent driving experience, and ensuring that the vehicle is always in the best operating state.

[0034] It can be seen that through the multi-modal information fusion technology, combined with various interaction methods such as speech recognition, gesture recognition, and touch operation, a more natural and intuitive intelligent interaction experience is achieved. This not only improves the usability of the system but also reduces the visual requirements and operation complexity of the driver, thus enhancing driving safety. Moreover, in the intelligent driving mode, the intelligent control system of the steering wheel can closely cooperate with the vehicle's autonomous driving system to provide intelligent driving assistance suggestions to the driver in a timely manner.

[0035] In addition, the system also has a learning ability and can make personalized adjustments according to the driver's usage habits and preferences, further enhancing the convenience and comfort of intelligent interaction. For example, when it detects that the driver is fatigued and the vehicle speed is relatively high, it can automatically reduce the vehicle speed and remind the driver to rest through the vibration of the steering wheel and voice prompts, and automatically adjust in-vehicle devices such as the seat, rearview mirror, and air conditioner according to the driver's driving habits and real-time status.

[0036] In summary, the present invention provides an intelligent control system for a steering wheel, which effectively prevents accidents caused by the driver's hands leaving the wheel by using high-precision multi-modal hands-off detection.

[0037] At the same time, multi-modal information fusion and intelligent interaction can promptly detect the abnormal state of the driver and take corresponding measures. The deep integration with the intelligent driving function fully exerts the important role of the steering wheel in intelligent driving, ensures a safe transition during the switching process between autonomous driving and manual driving, promotes the coordinated development of autonomous driving and manual driving, and provides new technical ideas and solutions for the development of future intelligent vehicles.

[0038] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
