[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used 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 running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a car seat vibration optimization device, etc. The following takes the car 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 the present application.

[0054] In this embodiment, the vehicle seat vibration optimization device 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 should be noted that when the vehicle is driving, the vibration of the road surface, power system and other excitation sources will be transmitted to the body. The greater the excitation, the greater the body vibration acceleration; as the vehicle speed increases, the seat vibration acceleration will also increase, and the acceptable seat vibration acceleration value for the human body will also increase; when the seat pneumatic massage function is turned on, the driver will ignore the seat vibration caused by the road surface, power system and other excitations due to the large vibration caused by the pneumatic massage. Therefore, it is necessary to detect the vehicle speed, body vibration acceleration, and seat pneumatic massage function on and off signals in real time, and suppress the seat vibration based on them. For example, when the seat pneumatic massage function is turned off, when the car is driving on a smooth road and the body vibration acceleration is small, the seat vibration suppression function is turned off; when the car is driving on a bumpy road and the body vibration acceleration exceeds the preset body vibration acceleration target, the seat vibration suppression function is turned on.

[0058] It should be understood that the 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 driving 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) and the sensors 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 the target seat airbag inflation amount based on the vehicle body vibration acceleration and the vehicle speed when it is determined that the seat pneumatic massage function is not turned on according to the seat pneumatic massage function on / off signal 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 is 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 target value of the body vibration acceleration, 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] According to the current vehicle speed and vehicle body vibration acceleration, the preset seat vibration adjustment parameter table is queried; and the corresponding seat airbag inflation amount recommended 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 a specific implementation, according to the inflation amount of the seat airbag, the air pump receives a control signal and inflates the airbag according to the preset inflation amount, 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 should be noted that the excitation sources of seat vibration include road surface, power system, cooling fan, compressor, blower, etc. The vibration generated by the excitation source is transmitted to the seat through the vehicle body. When the frequency of the excitation source is equal to or close to the natural frequency of the seat, the seat will vibrate greatly. When the excitation source is coupled with the vehicle body frequency, the vehicle body will amplify the vibration generated by the excitation, causing the seat to vibrate more severely, also known as vibration. The magnitude of seat vibration is characterized by the vibration acceleration of the seat back (referred to as seat vibration acceleration).

[0068] The seat vibration acceleration is equal to the seat rail vibration acceleration multiplied by the seat vibration transmissibility. The seat vibration transmissibility refers to the ratio of the seat vibration acceleration to the seat rail input acceleration. The seat vibration acceleration is generally the vibration acceleration of the seat cushion or backrest. The seat vibration transmissibility directly affects the passenger's comfort, and its size is closely related to the seat comfort. If the seat vibration transmissibility is high, it means that the seat has a strong ability to transmit vibrations, and passengers will be more likely to feel vibrations from excitation sources such as the road surface, reducing riding comfort. On the contrary, if the seat vibration transmissibility is low, the seat has a stronger ability to absorb and mitigate vibrations, and passengers will feel less vibration during the ride, improving riding comfort. Therefore, to suppress seat shaking, the seat vibration transmissibility must be reduced.

[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 are: ① Improve the vibration isolation performance of the seat foam material; ② Improve the stiffness of the seat back; ③ Improve the connection stiffness between the seat cushion and the backrest; ④ Add a vibration absorber to the seat back. Solutions ①-③ require changes to the structural design of the seat, which have a long cycle and high cost, and are rarely used in the later stages of product development. Affected by cost and cycle, adding a vibration absorber to the seat back is the most commonly used 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, the 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 suppression of seat vibration. 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 schematic diagram of the seat back airbag layout is shown in the figure. Figure 2 When the pneumatic seat massage function is turned on, the vibration caused by the pneumatic massage is large, and the occupants will ignore the seat vibrations stimulated by the road surface, power system, etc. When the pneumatic seat massage function is turned 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 in 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 a specific implementation, the target seat airbag inflation volume is calculated according to a seat vibration adjustment parameter table or a 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 recognizable by the air pump control system to ensure accurate transmission of the signal.

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

[0076] It should be noted that the air pump control signal is a signal generated by the CPU and is used to instruct 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 the 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 in 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 the seat vibration amplitude based on the 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 flatness; the seat vibration prediction model is used to predict the seat vibration amplitude based on the road surface type and flatness; 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 vibration amplitude of the seat according to 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 type and road roughness 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 vehicle 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: According to the vehicle speed and body vibration acceleration signals obtained by the vehicle status acquisition module, query the seat vibration adjustment parameter table, obtain the seat airbag inflation volume, and send 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, drives the air pump of the pneumatic massage seat to inflate the air bag, that is, by adjusting the inflation amount of the seat air bag to reduce the seat vibration transmission rate, thereby suppressing the seat vibration.

[0100] The present embodiment provides a method for optimizing the vibration of automobile seats, 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 according to 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-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 , step S20, including steps S201-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 the specific implementation, the vehicle is driven under the condition where the seat vibrates, the seat airbag inflation volume is adjusted, and the seat vibration acceleration is detected at the same time until the seat vibration acceleration meets the target value, and the vehicle speed, body vibration acceleration, and seat airbag inflation volume are recorded. The vehicle driving condition is changed, and the above steps are repeated until the test of all conditions where the vehicle seat vibrates is completed. The results are summarized into a seat vibration adjustment parameter table.

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

[0106] Step A11: simulating a preset seat vibration condition, and monitoring 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 conditions are collected.

[0108] Step A12: When the seat airbag inflation volume is adjusted until the seat vibration acceleration reaches a preset seat vibration acceleration value, a seat vibration adjustment parameter table is established 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 amount 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 amount are recorded when the preset seat vibration acceleration value is reached; 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 amount.

[0110] Step S202, querying the seat vibration adjustment parameter table based on the vehicle body vibration acceleration and the vehicle speed to determine the 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.
