Description

Technical Field

[0001] This invention belongs to the field of intelligent control technology for automotive seats, specifically relating to an intelligent control method, system, computer equipment, and storage medium for automotive seats. Background Technology

[0002] With the rapid development of the automotive industry, the number and types of cars are constantly increasing, especially the explosive growth of new energy vehicle technology in recent years.

[0003] With new players entering the automotive market, more and more new features and experiences are emerging. Through facial recognition technology, the system can synchronize the seats, steering wheel, ambient lighting, and air conditioning (based on the user's position memory when leaving the vehicle), providing an unprecedented level of comfort.

[0004] Nevertheless, current intelligent car seat control systems still cannot achieve truly proactive and adaptive comfort adjustments based on user driving habits and environmental factors. When users adjust seat parameters multiple times, manual adjustments are required, resulting in a poor user experience.

[0005] In summary, current intelligent car seat control systems suffer from the problem that users need to manually adjust the seat parameters multiple times when they want to make multiple adjustments, resulting in a poor user experience. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent control method, system, computer device, and storage medium for automobile seats, which solves the problem in the prior art that when users want to adjust the seat parameters multiple times, they need to manually adjust the seat parameters multiple times, resulting in a poor user experience.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides an intelligent control system for automobile seats, including an entertainment host module, a zone controller module, a seat control module, a digital key module, and an image capturing module;

[0009] The entertainment host module provides a seat adjustment switch, a seat memory interface, a seat intelligent control interface, and a seat ventilation and heating interface. The area controller module receives seat adjustment requests from users when they press the seat adjustment switch on the entertainment host module, and executes the seat adjustment action accordingly. The seat control module controls the automatic adjustment of the seat based on image information captured by the image capture module. The digital key module receives key location information from the in-vehicle positioning module and also provides unlocking / locking requests. The image capture module captures images of the overall appearance, faces, and key parts of the driver and passengers inside and outside the vehicle.

[0010] A further improvement of the present invention is that it also includes a vehicle infotainment screen module, which is used to provide users with a seat adjustment switch setting interface and to display the seat adjustment switch status.

[0011] A further improvement of the present invention is that the automatic adjustment includes automatic adjustment of the seat headrest and neck, automatic adjustment of shoulder support, automatic adjustment of side wing wrapping, automatic adjustment of lumbar support, automatic adjustment of seat cushion firmness and softness and automatic adjustment of thigh support.

[0012] A further improvement of the present invention is that if the user manually adjusts the automatically adjusted area, the entertainment host module learns the user's operating habits and automatically generates an AI model. When the user gets in the car again, the AI ​​model actively sends out seat adjustment parameters based on the user's operating habits.

[0013] A further improvement of the present invention is that the image capturing module includes a surround-view camera, a panoramic camera, and a driver monitoring system camera. The surround-view camera and the panoramic camera are used to capture image information of the overall appearance, face, and key parts of the people outside the vehicle, and the driver monitoring system camera is used to capture image information of the overall appearance, face, and key parts of the driver inside the vehicle.

[0014] A further improvement of the present invention is that the driver monitoring system camera is also used for facial recognition. After successful facial recognition, the entertainment host module matches the memorized car seat parameters with the facial information recognized by the driver monitoring system camera.

[0015] A further improvement of the present invention is that the entertainment host module uses a deep learning algorithm to obtain the user's human body envelope data.

[0016] Secondly, the present invention provides an intelligent control method for automobile seats, employing the intelligent control system for automobile seats described above. This intelligent control method for automobile seats includes the following steps:

[0017] 1) The user presses the seat adjustment switch to send a seat adjustment request;

[0018] 2) Receive seat adjustment requests from users when they press the seat adjustment switch;

[0019] 3) The automatic adjustment of the seat is controlled based on the overall appearance, face and key parts of the driver and passengers inside and outside the vehicle.

[0020] Thirdly, the present invention provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the intelligent control method for car seats described above.

[0021] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described intelligent control method for automotive seats.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This invention is an improved version of the existing intelligent car seat control system. Compared with existing intelligent car seat control systems, the proposed intelligent car seat control system incorporates a seat control module. This module controls the automatic adjustment of the seat, while the area controller module receives the user's seat adjustment request and executes the adjustment action, thereby adaptively adjusting the car seat parameters. Compared with existing technologies, this invention effectively solves the problem that existing technologies require users to manually adjust the seat parameters multiple times when they want to adjust them, resulting in a poor user experience.

[0029] To further understand the content of this invention, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0030] The intelligent car seat control system proposed in this invention controls the automatic adjustment of the seat through a seat control module, while a zone controller module receives the user's seat adjustment request and executes the adjustment action to adaptively adjust the car seat parameters. Compared with the prior art, this invention effectively solves the problem that in the prior art, when the user wants to adjust the seat parameters multiple times, the user experience is poor due to the need for manual adjustment of the seat parameters multiple times.

[0031] Example of an intelligent control system for car seats:

[0032] The interaction diagram between the modules of the intelligent car seat control system of this invention is as follows: Figure 1 As shown, Figure 1 In this invention, LVDS represents a differential signaling technology used for video transmission, LIN represents a data communication bus method (low speed), and CANFD represents a data communication bus method (high speed). The specific technical solution of this invention is described below:

[0033] The intelligent automotive seat control system of this invention includes an entertainment host module (also called an entertainment host ICC), a zone controller module (also called a zone controller ZCU), a seat control module (also called a seat control SCM), a digital key module (also called a digital key BNCM), a vehicle screen module, an image capture module, and a vehicle screen module. Wherein, ICC stands for Infotainment Computing Center, ZCU stands for Zone Control Unit, SCM stands for Seat Control Module, and BNCM stands for Bluetooth NFC Control Module.

[0034] The infotainment system module provides seat adjustment switches, seat memory interfaces, seat intelligent control interfaces, seat ventilation and heating interfaces, and status displays for corresponding buttons and interfaces. The area controller module receives seat adjustment requests from the user when pressing the seat adjustment switch on the infotainment system module, and executes the seat adjustment action accordingly. The seat control module controls the automatic adjustment of the seat based on image information captured by the image capture module. The digital key module receives key location information from the in-vehicle positioning module and also provides unlocking / locking requests. The image capture module captures images of the overall appearance, faces, and key areas of the driver and other occupants. The vehicle screen module provides the user with a seat adjustment switch settings interface and displays the seat adjustment switch status. The digital key module uses UWB (Ultra Wide Band) technology to accurately locate the user's handheld device (supporting UWB technology and a mobile phone or physical key bound to the vehicle). To establish a connection with the user's handheld device, the digital key module can automatically recognize the user's approach to the vehicle, thereby activating the entire intelligent car seat control system. When unlocking a car manually using a traditional remote key, the user's location cannot be accurately determined; the user may be right next to the car door, but the system may not be able to identify the user's external features.

[0035] The image capture module includes surround-view cameras, panoramic cameras, and a driver monitoring system camera (also called a DMS camera). The surround-view and panoramic cameras capture images of the overall appearance, face, and key features of people outside the vehicle. The driver monitoring system camera captures images of the overall appearance, face, and key features of the driver inside the vehicle. The driver monitoring system camera also performs facial recognition. After successful facial recognition, the infotainment system module matches the facial information recognized by the driver monitoring system camera with the memorized car seat parameters. Using only surround-view cameras may have insufficient image recording capabilities, such as high blind spots and multi-angle blind spots. However, using both surround-view and panoramic cameras allows for the acquisition of the user's overall appearance features from multiple angles. Therefore, this embodiment uses both surround-view and panoramic cameras to capture images of the overall appearance, face, and key features of people outside the vehicle. DMS stands for Driver Monitor System.

[0036] The seat control module of this invention specifically controls the automatic adjustment of the seat headrest and neck support, shoulder support, side bolster support, lumbar support, seat cushion firmness, and thigh support, such as... Figure 2 As shown.

[0037] The overall control principle of the intelligent car seat control system of this invention is as follows: Figure 3As shown, when the vehicle is parked and locked, a user approaching the vehicle with a handheld device and entering the unlocking area, the area controller module automatically unlocks the vehicle based on the key location information sent by the digital key module. The infotainment system module receives the key location information from the digital key module and controls the corresponding surround-view and panoramic cameras outside the vehicle to begin capturing images. When the user opens the driver's side door, the DMS camera activates facial recognition. After successful facial recognition, the infotainment system module automatically adjusts six function areas of the seat based on the facial recognition information detected by the DMS camera (automatic adjustment of the headrest and neck support, shoulder support, side bolsters, lumbar support, seat cushion firmness, and thigh support). If the user manually adjusts the automatically adjusted area, the entertainment system module learns the user's operating habits and automatically generates an AI model. The next time the user gets in the car, the AI ​​model will proactively send seat adjustment parameters based on the user's operating habits, such as seat height and headrest parameters. This enables the system to adaptively adjust the seat and update functions based on the user's body characteristics and operating habits. The AI ​​model includes parameters for various body parts, joint positions, leg positions, waist positions, and body size.

[0038] When a user approaches the vehicle, the entertainment host module's image capture module first captures images of the user's overall appearance, face, and key body parts outside the vehicle. Then, it uses a deep learning algorithm (RNN) to extract deep human features, followed by 3D human keypoint detection (selecting human joints as skeleton points based on the human body's structure). A topological structure between joints is established, and the skeleton joints pull the bound vertices to the target pose, generating external skin features of the human body. This yields the user's human body envelope data. The principle diagram of this invention using deep learning algorithms to obtain the user's human body envelope data is shown below. Figure 4 As shown.

[0039] The workflow of the intelligent car seat control system of this invention is as follows: Figure 5 As shown, the user first approaches the vehicle, then the external cameras (surround view camera and panoramic camera) are activated to identify human (also called personnel) features. When the user opens the car door, it first determines whether to perform face recognition through the DMS camera. When face recognition is performed through the DMS camera, the entertainment host module matches the memorized car seat parameters according to the identified personnel information ID, and then uses the AI ​​big model algorithm to learn the user's operating habits and adaptively adjust the parameters of the six functional areas of the car seat.

[0040] Implementation examples of intelligent control methods for car seats:

[0041] The intelligent control method for automobile seats, employing the intelligent control system for automobile seats described above, includes the following steps:

[0042] 1) The user presses the seat adjustment switch to send a seat adjustment request;

[0043] 2) Receive seat adjustment requests from users when they press the seat adjustment switch;

[0044] 3) The automatic adjustment of the seat is controlled based on the overall appearance, face and key parts of the driver and passengers inside and outside the vehicle.

[0045] This embodiment of the intelligent control method for automotive seats is implemented using the intelligent control system for automotive seats described above. The interaction diagram between the modules of the intelligent control system for automotive seats in this embodiment is shown below. Figure 1 As shown, the intelligent vehicle seat control system in this embodiment includes an entertainment host module (also called an entertainment host ICC), a zone controller module (also called a zone controller ZCU), a seat control module (also called a seat control SCM), a digital key module (also called a digital key BNCM), a vehicle screen module, an image capture module, and a vehicle screen module. Wherein, ICC stands for Infotainment Computing Center, ZCU stands for Zone Control Unit, SCM stands for Seat Control Module, and BNCM stands for Bluetooth NFC Control Module.

[0046] The infotainment system module provides seat adjustment switches, seat memory interfaces, seat intelligent control interfaces, seat ventilation and heating interfaces, and status displays for corresponding buttons and interfaces. The area controller module receives seat adjustment requests from the user when pressing the seat adjustment switch on the infotainment system module, and executes the seat adjustment action accordingly. The seat control module controls the automatic adjustment of the seat based on image information captured by the image capture module. The digital key module receives key location information from the in-vehicle positioning module and also provides unlocking / locking requests. The image capture module captures images of the overall appearance, faces, and key areas of the driver and other occupants. The vehicle screen module provides the user with a seat adjustment switch settings interface and displays the seat adjustment switch status. The digital key module uses UWB (Ultra Wide Band) technology to accurately locate the user's handheld device (supporting UWB technology and a mobile phone or physical key bound to the vehicle). To establish a connection with the user's handheld device, the digital key module can automatically recognize the user's approach to the vehicle, thereby activating the entire intelligent car seat control system. When unlocking a car manually using a traditional remote key, the user's location cannot be accurately determined; the user may be right next to the car door, but the system may not be able to identify the user's external features.

[0047] The image capture module includes surround-view cameras, panoramic cameras, and a driver monitoring system camera (also called a DMS camera). The surround-view and panoramic cameras capture images of the overall appearance, face, and key features of people outside the vehicle. The driver monitoring system camera captures images of the overall appearance, face, and key features of the driver inside the vehicle. The driver monitoring system camera also performs facial recognition. After successful facial recognition, the infotainment system module matches the facial information recognized by the driver monitoring system camera with the memorized car seat parameters. Using only surround-view cameras may have insufficient image recording capabilities, such as high blind spots and multi-angle blind spots. However, using both surround-view and panoramic cameras allows for the acquisition of the user's overall appearance features from multiple angles. Therefore, this embodiment uses both surround-view and panoramic cameras to capture images of the overall appearance, face, and key features of people outside the vehicle. DMS stands for Driver Monitor System.

[0048] The overall control principle of the intelligent control method for car seats in this embodiment is as follows: Figure 3As shown, when the vehicle is parked (also called locked) or locked, a user carrying a handheld device (supporting UWB technology and a mobile phone or physical key bound to the vehicle) approaches the vehicle and enters the unlocking area. The area controller module, based on the key location information sent by the digital key module, controls the vehicle to automatically unlock. The entertainment head unit module receives the key location information sent by the digital key module and controls the corresponding surround-view and panoramic cameras outside the vehicle to start capturing images. When the user opens the driver's side door, the DMS camera activates facial recognition. After successful facial recognition, the entertainment head unit module automatically adjusts six functional areas of the seat based on the facial recognition information recognized by the DMS camera (automatic adjustment of the headrest and neck, shoulder support, side bolsters, lumbar support, seat cushion firmness, and thigh support). If the user manually adjusts the automatically adjusted area, the entertainment system module learns the user's operating habits and automatically generates an AI model. The next time the user gets in the car, the AI ​​model will proactively send seat adjustment parameters based on the user's operating habits, such as seat height and headrest parameters. This enables the system to adaptively adjust the seat and update functions based on the user's body characteristics and operating habits. The AI ​​model includes parameters for various body parts, joint positions, leg positions, waist positions, and body size.

[0049] The specific process of the intelligent control method for car seats in this embodiment is as follows: Figure 5 As shown, the user first approaches the vehicle, then the external cameras (surround view camera and panoramic camera) are activated to identify human (also called personnel) features. When the user opens the car door, it first determines whether to perform face recognition through the DMS camera. When face recognition is performed through the DMS camera, the entertainment host module matches the memorized car seat parameters according to the identified personnel information ID, and then uses the AI ​​big model algorithm to learn the user's operating habits and adaptively adjust the parameters of the six functional areas of the car seat.
