Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to an automobile seat system and method for intelligently adjusting and alleviating a back-pushing feeling. Background Art

[0002] In the current automotive industry, with the rapid development of electric vehicles and autonomous driving technology, the passenger riding experience has become one of the key concerns of major automakers. Among them, the "push back feeling" is a factor that is closely related to the vehicle's acceleration performance and directly affects the comfort of the driver and passengers, and is receiving more and more attention.

[0003] When traditional high-performance vehicles accelerate suddenly, the strong push-back feeling can give the driver a stimulating driving experience, but for passengers who ride for a long time or are sensitive to their bodies, this feeling may cause discomfort or even health problems, such as increased neck pressure and fatigue in the waist and back.

[0004] In order to balance driving pleasure and riding comfort, intelligent seat systems have gradually become a hot topic in recent years. However, existing technologies mostly focus on seat vibration control, posture adjustment, and temperature management, and there is still a lack of effective solutions for accurately controlling the push-back feeling generated during acceleration. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a car seat system and method for intelligent adjustment to reduce the push-back feeling. Through the monitoring of multiple sensors and the cooperation of active response mechanisms, the seat shape can be adjusted instantly to ensure that while ensuring safety and driving pleasure, the discomfort caused to passengers by sudden acceleration or deceleration is minimized.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In a first aspect, the present invention provides an automobile seat system for intelligently adjusting and alleviating a back-pushing feeling, comprising:

[0008] The sensor unit includes an acceleration sensor, a pressure sensor and a gyroscope arranged on the seat, which are used to capture the dynamic changes of the vehicle during acceleration and the body posture of the passenger; and also includes a heart rate monitoring sensor arranged on the seat, which is used to measure the physiological indicators of the passenger and evaluate his physiological response to the push back feeling;

[0009] Dynamic support adjustment unit, including seat adjustment components and airbags located in the seat bottom and backrest;

[0010] The controller unit calculates and adjusts the state of the seat adjustment component and the inflation amount in the airbag according to the monitoring data of the sensor unit to counteract the push-back feeling and thus reduce the discomfort of the passenger.

[0011] As a further implementation method, it also includes a personalized setting unit, which is used for passengers to set the intensity level of push-back relief according to personal preferences and retain the memory for automatic application next time.

[0012] As a further implementation method, it also includes a safety linkage unit for establishing a communication protocol with the vehicle's safety system. When emergency braking or collision warning is activated, the seat can automatically enter a fastened state.

[0013] In a second aspect, the present invention provides a method for intelligently alleviating a feeling of pushing back, which is performed using the automobile seat system for intelligently adjusting and alleviating a feeling of pushing back as described in the first aspect, and comprises the following steps:

[0014] The system starts to self-check to ensure the normal operation of each unit and obtain basic vehicle information and driving mode;

[0015] During driving, various sensors continuously monitor changes in vehicle acceleration, passenger body posture, pressure distribution and heart rate, and transmit the data to the controller in real time. The controller analyzes the data to determine the intensity of the push-back feeling and the possible degree of discomfort of the passengers under the current driving conditions. Based on the analysis results, the system quickly adjusts the airbag pressure distribution and the seat angle and hardness to counteract the push-back feeling and reduce passenger discomfort.

[0016] As a further implementation method, if the passenger's heart rate rises abnormally, the system adjusts the seat angle and hardness through the dynamic support adjustment unit to help the passenger relax and reduce psychological tension.

[0017] As a further implementation method, when a passenger takes a seat, the system enters the passenger identification process; if personal information has been stored, the passenger profile is automatically matched through biometrics or previously set preferences, and the seat is adjusted to the preferred settings; if it is a new passenger, comfort settings are provided, and the passenger is prompted to save personalized settings.

[0018] As a further implementation method, when the system receives a warning from the vehicle safety system, it immediately suspends non-essential adjustment actions and gives priority to ensuring passenger safety restraints.

[0019] As a further implementation, in the event of emergency braking or risk of collision, the seats can be quickly locked to enhance passenger fixation while maintaining comfort and breathing space.

[0020] As a further implementation method, the system records the adjustment effects and passenger feedback in each trip, continuously optimizes the algorithm model, and improves the comfort prediction and adaptability of future rides.

[0021] As a further implementation, when the vehicle is turned off or no passenger activity is detected for a long time, the system enters an energy-saving sleep mode.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The system of the present invention can monitor the status of passengers and cars in real time by integrating pressure sensors, acceleration sensors, gyroscopes and heart rate sensors. Among them, the acceleration sensor monitors the vehicle dynamics, combines algorithm analysis to predict the acceleration trend and passenger status, and then instructs the built-in active response mechanism to adjust the seat shape immediately, ensuring that while ensuring safety and driving pleasure, the discomfort caused to passengers by sudden acceleration or deceleration is minimized, achieving effective management of the push-back feeling when the car accelerates, and improving riding comfort and safety.

[0024] 2. The present invention can quickly adjust the pressure distribution of the airbag according to the analysis results of the controller, increase the inflation volume of the back support airbag during rapid acceleration to reduce the forward rush; appropriately release the pressure during deceleration to reduce the backward pressure on the body. When the passenger's heart rate rises abnormally, the system will appropriately adjust the seat angle and hardness to help the passenger relax and reduce psychological tension.

[0025] 3. The present invention also includes a personalized setting unit, which allows different passengers to preset the degree of mitigation of the push-back feeling according to their own preferences, further improving the comfort and satisfaction of the ride. In addition, the system can save each passenger's personalized settings and automatically apply them the next time you ride, enhancing the continuity and convenience of the user experience. The personalized setting unit can not only significantly improve the passenger experience, but will also become a key factor in the differentiated competition of future high-end models.

[0026] 4. The safety linkage unit of the present invention can establish a communication protocol with the vehicle's safety system. When emergency braking or collision warning is activated, the seat system will temporarily release the function of reducing the push-back feeling. The seat system automatically enters a tightening state to strengthen the passenger fixation, ensure that the passenger is in the most favorable position and posture for safety protection, and avoid the safety affected by looseness during seat adjustment.

[0035] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0036] Embodiment 1

[0037] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, an automobile seat system with intelligent adjustment and mitigation of back pushing feeling includes a sensor unit, a dynamic support adjustment unit, a personalized setting unit, a safety linkage unit and a controller.

[0038] In this embodiment, the controller adopts a microcontroller (MCU). It is understandable that in other embodiments, any controller that can receive and process data and control the actions of other devices can be used, and is not limited to the microcontroller (MCU) of this embodiment. For other controllers, this embodiment will not list them one by one.

[0039] The sensor unit includes a heart rate monitoring sensor 1, a pressure sensor 2, an acceleration sensor and a gyroscope 4. The sensors are precisely installed in the seat frame using multi-dimensional sensor array integration technology. In this embodiment, the acceleration sensor and the gyroscope 4 are installed at the bottom of the seat, and the pressure sensor 2 is installed at the backrest and seat surface of the seat. The pressure sensor 2, the acceleration sensor and the gyroscope 4 are used to accurately capture the dynamic changes of the vehicle during acceleration and the body posture of the passenger. Specifically, they can accurately capture the acceleration changes, direction changes and body pressure distribution of the passenger under different driving conditions. The heart rate monitoring sensor 1 is installed on the contact surface of the backrest of the seat, and non-contact measurements of the passenger's physiological indicators are performed to evaluate their physiological response to the push-back feeling. The heart rate monitoring sensor 1 can sense abnormal heart rate and prevent discomfort symptoms such as syncope caused by excessive heart rate in advance.

[0040] Sensor data is transmitted to the controller unit in real time via a high-speed communication interface, enabling instant response to vehicle dynamics.

[0041] The dynamic support adjustment unit includes a seat adjustment component and variable damping airbags 3 located at the bottom and back of the seat. During rapid acceleration, the airbag at the back is inflated to reduce the forward rush; during deceleration, the pressure is appropriately released to reduce the backward pressure on the body. The bottom airbag can change the hardness of the seat cushion to ensure that the cushion supports the passenger during acceleration. Both the airbag 3 and the seat adjustment component are driven by a micro electric servo motor. When the sensor unit detects a sudden increase in acceleration caused by vehicle acceleration, the controller uses a proprietary algorithm to analyze the vehicle acceleration pattern, predict the upcoming push-back intensity, and immediately calculate the required support force adjustment plan. The airbag 3 quickly adjusts the inflation volume based on the calculation results, and the seat adjustment component adjusts the seat angle to increase the reverse support for the passenger's body, simulating a force distribution that "counteracts" the push-back feeling, forming a reverse support force to counter the push-back feeling, so that the acceleration impact felt by the passenger can be alleviated, maintaining a smooth and comfortable riding experience, and reducing the discomfort of the passenger.

[0042] The system provided by the present invention can monitor the status of passengers and cars in real time by integrating pressure sensors, acceleration sensors, gyroscopes and heart rate sensors. Among them, the acceleration sensor monitors the vehicle dynamics, combines algorithm analysis to predict the acceleration trend and passenger status, and then instructs the built-in active response mechanism (such as electric motor driven lumbar support adjustment, airbag pressure adjustment, etc.) to adjust the seat shape in real time, ensuring that while ensuring safety and driving pleasure, the discomfort caused to passengers by sudden acceleration or deceleration is minimized. At the same time, it realizes the effective management of the push-back feeling when the car accelerates, improving the riding comfort and safety.

[0043] The personalized setting unit provides an in-vehicle touch screen or mobile phone APP, allowing passengers to set the push-back relief intensity level according to their personal preferences (personal physique, comfort requirements), including mild, moderate and severe relief modes. Even specific scene modes can be set, such as urban commuting and highway cruising. The system memorizes each passenger's settings and automatically matches personal profiles through face recognition or seat occupancy sensing to achieve intelligent personalized services and enhance the continuity and convenience of user experience. The personalized setting unit can not only significantly improve the passenger experience, but will also become one of the key factors for differentiated competition in future high-end models.

[0044] In addition to improving riding comfort, this embodiment also takes safety factors into consideration. The safety linkage unit establishes a communication protocol with the vehicle's safety system. When emergency braking or collision warning is activated, the seat system will temporarily release the function of alleviating the push-back feeling. The seat system automatically enters a tightening state to strengthen the passenger fixation, ensuring that the passenger is in the most favorable position and posture for safety protection, and avoiding the safety impact caused by looseness during seat adjustment. In addition, if extreme acceleration is detected (such as racing mode), the system will temporarily disable the push-back relief function to avoid interfering with the driver's control perception. At the same time, the safety linkage unit can also work in conjunction with the seat belt tensioner and other passive safety equipment to maximize passenger safety.

[0045] Embodiment 2

[0046] This embodiment provides a method for intelligently alleviating the push-back feeling. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the intelligent adjustment and mitigation of the push-back feeling of the automobile seat system as described in the first embodiment is adopted, and the following steps are included:

[0047] When the intelligent adjustment and push-back reduction car seat system is started, the microcontroller (MCU) executes a self-test program to check whether the sensor unit (accelerometer, pressure sensor, gyroscope, heart rate monitoring sensor), airbag, driver and communication module are connected normally, and confirm that all components are in standby state. The seat is synchronized with other vehicle systems through the vehicle network (such as CAN bus) to obtain basic vehicle information and current driving mode.

[0048] When a passenger takes a seat, the pressure sensor is activated and the system enters the passenger identification process. If personal information has been stored, the passenger profile is automatically matched through biometrics (such as heart rate) or previously set preferences, and the seat is adjusted to their preferred settings; if it is a new passenger, comfort settings are provided, and the passenger is prompted to save personalized settings through the in-vehicle screen or mobile phone APP.

[0049] During driving, various sensors continuously monitor changes in vehicle acceleration, passenger body posture, pressure distribution, and physiological reactions (such as changes in heart rate), and transmit the data to the microcontroller (MCU) in real time. Using built-in algorithms, these data are comprehensively analyzed to determine the intensity of the push back feeling and the possible discomfort of the passenger under the current driving conditions. Based on the analysis results, the system quickly adjusts the pressure distribution of the airbag, such as increasing the inflation volume of the backrest airbag during rapid acceleration to reduce the forward rush; appropriately releasing pressure during deceleration to reduce the body's backward pressure. When the heart rate rises abnormally, the system will appropriately adjust the seat angle and hardness to help passengers relax and reduce psychological tension.

[0050] Upon receiving a warning from the vehicle safety system (such as ABS activation, ESP intervention), non-essential adjustment actions will be suspended immediately to prioritize passenger safety restraints; in the event of emergency braking or collision risks, the seat will be quickly locked to enhance passenger fixation while maintaining a certain level of comfort and breathing space.

[0051] The system records the adjustment effect and passenger feedback (such as the number of manual fine-tuning) during each trip, and uses machine learning technology to continuously optimize the algorithm model to improve the prediction and adaptability of future ride comfort. It supports remote firmware updates, and manufacturers can push system upgrades, add new functions or improve existing logic based on market feedback and new technology developments.

[0052] When the vehicle is turned off or no passenger activity is detected for a long time, the system enters energy-saving sleep mode, shuts down the power of non-essential components, and maintains only minimum data monitoring to allow for quick wakeup. The next time the system is started, it quickly restores to the last used settings or default state, ready for a new riding experience.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
