[0050] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions, such as a vehicle seat vibration optimization device. The following uses the vehicle seat vibration optimization device as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a method for optimizing the vibration of a car seat, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle seat vibration optimization device method of this application.

[0054] In this embodiment, the vehicle seat vibration optimization method includes steps S10 to S30:

[0055] Step S10, obtaining the on / off signal of the seat pneumatic massage function, the vehicle body vibration acceleration and the vehicle speed;

[0056] In the specific implementation, the vehicle status is detected in real time, that is, the vehicle speed, body vibration acceleration, and seat pneumatic massage function on-off signal during driving are detected.

[0057] It's important to note that when a vehicle is in motion, vibrations from excitation sources like the road surface and powertrain are transmitted to the vehicle body. The greater the excitation, the greater the body vibration acceleration. As vehicle speed increases, seat vibration acceleration also increases, and the acceptable seat vibration acceleration for the human body also increases. When the pneumatic seat massage function is enabled, the driver may tend to ignore seat vibrations from excitations like the road surface and powertrain due to the high vibrations caused by the pneumatic massage. Therefore, it's necessary to monitor vehicle speed, body vibration acceleration, and the pneumatic seat massage function on / off signal in real time and use these signals to suppress seat vibration. For example, when the pneumatic seat massage function is disabled and the vehicle is traveling on smooth roads with low body vibration acceleration, the seat vibration suppression function is disabled. However, when the vehicle is traveling on bumpy roads and the body vibration acceleration exceeds the preset body vibration acceleration target, the seat vibration suppression function is enabled.

[0058] It should be understood that vehicle speed detection can be achieved by installing a vehicle speed sensor (such as a wheel speed sensor or a GPS speed sensor) to monitor the vehicle's speed in real time.

[0059] Vehicle body vibration acceleration detection can be achieved by installing acceleration sensors at key locations of the vehicle (such as shock absorber towers and seat rails), which collect vehicle body vibration data in real time.

[0060] The status detection of the seat pneumatic massage function can be achieved by monitoring the on and off status of the pneumatic massage function through the seat control module.

[0061] Step S20, determining a target seat airbag inflation volume based on the vehicle body vibration acceleration and vehicle speed when it is determined based on the seat pneumatic massage function on / off signal that the seat pneumatic massage function is not on and the vehicle body vibration acceleration is greater than a first preset vehicle body vibration acceleration value;

[0062] In the specific implementation, if the seat pneumatic massage function is turned on, the seat vibration suppression function will not be turned on; if the seat pneumatic massage function is not turned on and the body vibration acceleration is greater than the preset body vibration acceleration target value, the seat vibration adjustment parameter table will be queried according to the vehicle speed and body vibration acceleration to obtain the seat airbag inflation amount.

[0063] It should be noted that the first preset body vibration acceleration value, that is, the preset body vibration acceleration target value, serves as the starting threshold of the seat shake suppression function; when the seat pneumatic massage function is not turned on and the body vibration acceleration exceeds the preset target value, the CPU triggers the seat shake suppression function.

[0064] Based on the current vehicle speed and vehicle body vibration acceleration, a preset seat vibration adjustment parameter table is queried; and the corresponding seat airbag inflation volume recommendation value is obtained from the table.

[0065] Step S30: adjusting the seat according to the target seat airbag inflation amount to suppress seat vibration.

[0066] In the specific implementation, according to the inflation volume of the seat airbag, the air pump receives a control signal and inflates the airbag according to the preset inflation volume, ensuring that the air pressure in the airbag can reach the level required to reduce the seat vibration transmission rate, thereby suppressing seat shaking.

[0067] It's important to note that seat vibration can be caused by sources such as the road surface, powertrain, cooling fan, compressor, and blower. The vibrations generated by these sources are transmitted to the seat through the vehicle body. When the frequency of the source is equal to or close to the seat's natural frequency, the seat will vibrate significantly. When the source's frequency is coupled to the vehicle body's frequency, the body amplifies the vibrations, causing even more severe seat vibration, also known as jitter. The magnitude of seat jitter is measured by the seatback's vibration acceleration (referred to as seat vibration acceleration).

[0068] Seat vibration acceleration is equal to the seat track vibration acceleration multiplied by the seat vibration transmissibility. The seat vibration transmissibility is the ratio of the seat vibration acceleration to the seat track input acceleration. Seat vibration acceleration is generally the vibration acceleration of the seat cushion or backrest. The seat vibration transmissibility directly impacts passenger comfort, and its magnitude is closely related to seat comfort. A high seat vibration transmissibility indicates a strong vibration transmission capability, making passengers more susceptible to vibrations from excitation sources such as the road surface, reducing ride comfort. Conversely, a low seat vibration transmissibility indicates a greater ability to absorb and mitigate vibrations, resulting in less vibration perception and improved ride comfort. Therefore, to suppress seat vibration, it is necessary to reduce the seat vibration transmissibility.

[0069] The seat is a nonlinear system, and the vibration transmissibility of the seat will change with the magnitude of the excitation, which brings difficulties to the optimization of seat vibration. Common measures to reduce the vibration transmissibility of the seat include: ① Improving the vibration isolation performance of the seat foam material; ② Improving the stiffness of the seat back; ③ Improving the connection stiffness between the seat cushion and the backrest; ④ Adding vibration absorbers to the seat back. Solutions ①-③ require changes to the structural design of the seat, which are long and costly, and are rarely used in the later stages of product development. Due to the influence of cost and cycle, adding vibration absorbers to the seat back is the most common solution. Rubber vibration absorbers are usually used, and the frequency of the vibration absorber is the seat vibration frequency. Due to the deviation of the seat mode, the modal deviation caused by the seat adjustment position, the modal deviation of whether the seat is occupied or not, and the modal deviation of the rubber vibration absorber, its vibration reduction effect is unstable.

[0070] For pneumatic massage seats, the air volume of the seat airbags can be adjusted through control strategies to reduce the seat vibration transmission rate, thereby suppressing seat vibration and achieving zero-cost seat vibration suppression. Pneumatic massage is to place airbags at the waist, side wings, legs and other positions of the seat back, and control the movement of the airbags in different modes through software to achieve the massage effect. The seat back airbag layout diagram is shown below. Figure 2 When the pneumatic massage function is on, the vibration caused by the pneumatic massage is so large that the occupants will ignore the seat vibrations caused by the road surface, power system, etc. When the pneumatic massage function is off, the seat vibration transmission rate can be reduced by adjusting the inflation volume of the air bag, thereby suppressing the seat vibration. The seat vibration optimization effect is shown as follows: Figure 3 shown.

[0071] In a feasible implementation, step S30 may include steps A11 to A12:

[0072] Step A11: generating an air pump control signal based on a target seat airbag inflation amount;

[0073] In the specific implementation, the target seat airbag inflation volume is calculated according to the seat vibration adjustment parameter table or prediction model; based on the target inflation volume, the CPU generates a corresponding air pump control signal, which includes the flow and pressure parameters required to achieve the target inflation volume.

[0074] It should be noted that the control signal may also be encoded into a format that can be recognized by the air pump control system to ensure accurate signal transmission.

[0075] Step A12: Adjust the flow rate and pressure of the air pump based on the air pump control signal, control the air bag to reach the target inflation volume, reduce the seat vibration transmission rate, and thus suppress seat vibration.

[0076] It should be noted that the air pump control signal is a signal generated by the CPU that instructs the air pump on how to adjust its flow rate and pressure to achieve the target inflation volume;

[0077] The flow and pressure regulation process is that the air pump adjusts its working parameters according to the control signal to control the inflation process of the air bag.

[0078] In the specific implementation, the air pump control system receives a control signal from the CPU; the air pump adjusts its flow and pressure according to the control signal to control the inflation process of the air bag; the pressure inside the air bag is monitored in real time through the pressure sensor to ensure that the inflation volume reaches the target value.

[0079] Before the step of adjusting the seat according to the target seat airbag inflation amount to suppress seat vibration, the method further includes:

[0080] Obtain traffic data;

[0081] Determine the road surface type and road surface smoothness based on road condition data;

[0082] Predict seat vibration amplitude based on road surface type and road surface smoothness;

[0083] The target seat airbag inflation volume is adjusted in real time according to the seat vibration amplitude.

[0084] In the specific implementation, vehicle-mounted sensors (such as cameras, lidar) or map data services are used to obtain road condition information; the road condition data is analyzed to determine the road surface type (such as asphalt, cement, gravel) and road surface smoothness; the seat vibration prediction model is used to predict the seat vibration amplitude based on the road surface type and smoothness; based on the predicted seat vibration amplitude, the target seat airbag inflation volume is adjusted in real time to adapt to different road conditions.

[0085] Furthermore, the step of predicting the seat vibration amplitude based on the road surface type and road surface smoothness includes:

[0086] Obtain historical road condition data, historical seat vibration amplitude, and historical seat airbag inflation volume;

[0087] The seat vibration prediction model is obtained by model training based on historical road condition data, historical seat vibration amplitude and historical seat airbag inflation volume;

[0088] The seat vibration prediction model is used to predict the road surface type and road surface smoothness to obtain the seat vibration amplitude.

[0089] In the specific implementation, historical road condition data, historical seat vibration amplitude and historical seat airbag inflation volume are collected; model training is performed based on historical data to obtain a seat vibration prediction model; and the accuracy and reliability of the seat vibration prediction model are evaluated through a validation set.

[0090] Furthermore, this strategy also includes:

[0091] After the airbag is inflated, the seat vibration acceleration is obtained;

[0092] Perform vibration suppression evaluation based on seat vibration acceleration to obtain evaluation results;

[0093] When the evaluation result is that the seat vibration acceleration is greater than the second preset body vibration acceleration value, continue to adjust the target seat airbag inflation amount until the target seat airbag inflation amount is less than the second preset body vibration acceleration value, wherein the second preset body vibration acceleration value is less than the first preset body vibration acceleration value.

[0094] It should be noted that seat vibration acceleration, that is, the vibration acceleration of the seat caused by uneven road surface during driving, is an important parameter for evaluating seat comfort.

[0095] In a specific implementation, after the airbag is inflated, a seat vibration acceleration sensor is used to monitor the actual vibration of the seat; the seat vibration acceleration is compared with a preset vibration acceleration value to evaluate the vibration suppression effect; if the seat vibration acceleration exceeds a second preset value, the target seat airbag inflation amount is continued to be adjusted until the vibration acceleration is lower than this value.

[0096] The present invention also relates to a seat vibration automatic adjustment system, comprising:

[0097] Vehicle status acquisition module: obtains vehicle speed and vehicle speed vibration acceleration, where the body vibration acceleration signal is obtained by the body acceleration sensor of the CDC shock absorber system, and the vehicle speed is obtained by the vehicle control unit.

[0098] Data processing module: Based on the vehicle speed and body vibration acceleration signals obtained by the vehicle status acquisition module, it queries the seat vibration adjustment parameter table, obtains the seat airbag inflation volume, and sends instructions to the execution module.

[0099] Execution module: The seat pneumatic massage control unit executes the seat vibration suppression strategy according to the instructions of the data processing module, that is, it drives the air pump of the pneumatic massage seat to inflate the air bag, that is, by adjusting the inflation volume of the seat air bag to reduce the seat vibration transmission rate, thereby suppressing seat vibration.

[0100] This embodiment provides a method for optimizing automobile seat vibration, which obtains the on / off signal of the seat pneumatic massage function, the vehicle body vibration acceleration and the vehicle speed; when it is determined based on the on / off signal of the seat pneumatic massage function that the seat pneumatic massage function is not turned on and the vehicle body vibration acceleration is greater than a first preset vehicle body vibration acceleration value, the target seat airbag inflation amount is determined based on the vehicle body vibration acceleration and the vehicle speed; the seat is adjusted according to the target seat airbag inflation amount to suppress seat vibration, and by adjusting the seat airbag inflation amount, the seat vibration is effectively suppressed, the riding comfort is improved, and the vehicle seat vibration problem is solved.

[0101] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 Step S20 includes steps S201 to S202:

[0102] Step S201, obtaining a seat vibration adjustment parameter table;

[0103] It should be noted that the seat vibration adjustment parameter table is the relationship between the seat airbag inflation volume and the vehicle body vibration acceleration and vehicle speed. It is obtained through actual vehicle testing and stored in the data processing module.

[0104] In practice, the vehicle is driven under conditions where seat vibration occurs, and the seat airbag inflation volume is adjusted while the seat vibration acceleration is monitored until the acceleration meets the target value. The vehicle speed, body vibration acceleration, and seat airbag inflation volume are recorded. The vehicle driving conditions are varied, and the above steps are repeated until all conditions under which the vehicle seat vibration occurs are tested. The results are summarized in a table of seat vibration adjustment parameters.

[0105] In a feasible implementation, step S201 may include steps A11 to A12:

[0106] Step A11: Simulate a preset seat vibration condition and monitor the vehicle body vibration acceleration and vehicle speed in real time;

[0107] In the specific implementation, a series of preset seat vibration conditions are defined, including different vehicle speeds and road types; acceleration sensors and vehicle speed sensors are installed to monitor the vehicle body vibration acceleration and vehicle speed in real time; and vehicle body vibration acceleration and vehicle speed data under different working conditions are collected.

[0108] Step A12: Adjust the seat airbag inflation volume until the seat vibration acceleration reaches a preset seat vibration acceleration value, and establish a seat vibration adjustment parameter table based on the current vehicle body vibration acceleration, the current vehicle speed, and the current seat airbag inflation volume.

[0109] In a specific implementation, the inflation volume of the seat airbag is adjusted until the seat vibration acceleration reaches a preset seat vibration acceleration value; the vehicle body vibration acceleration, vehicle speed and seat airbag inflation volume when the preset seat vibration acceleration value is reached are recorded; and a seat vibration adjustment parameter table is established based on the recorded data, which includes the vehicle body vibration acceleration, vehicle speed and corresponding seat airbag inflation volume.

[0110] Step S202 : querying a seat vibration adjustment parameter table based on the vehicle body vibration acceleration and the vehicle speed to determine a target seat airbag inflation amount.

[0111] In the specific implementation, the current vehicle body vibration acceleration and vehicle speed are obtained in real time; based on the real-time data, the corresponding seat airbag inflation volume is queried in the seat vibration adjustment parameter table; and the target seat airbag inflation volume is determined as the basis for adjusting the seat airbag.

[0112] This embodiment provides a method for optimizing automobile seat vibration, obtaining a seat vibration adjustment parameter table; querying the seat vibration adjustment parameter table based on the vehicle body vibration acceleration and vehicle speed, determining the target seat airbag inflation amount, ensuring the accuracy and practicality of the seat vibration adjustment parameter table, thereby achieving more effective seat vibration control and improving ride comfort.
