Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] See Figures 1-4 As shown in the figure, this application provides a method for obtaining a seat vibration target basis, which includes the following steps:

[0063] S1. Vibration is generated in response to vibration control commands using a pre-installed vibrator on the seat;

[0064] S2. Monitor and obtain the vibration intensity of the seat, the brainwave intensity of the person being tested in the seat, and the vibration perception intensity;

[0065] S3. Based on the seat vibration intensity corresponding to different vibration control commands and the brainwave intensity and vibration perception intensity of different test subjects located on the seat, construct a vibration relationship function.

[0066] In this embodiment of the application, a seat vibration performance target is obtained, and a target value is set for the seat vibration of different models to prevent the seat vibration target from being set too strict or too lenient. This ensures that the mass-produced models are competitive in the market while also reducing R&D and manufacturing costs.

[0067] In addition, it can help test the vibration isolation performance of the seat, which can help with the positive development of the seat.

[0068] Furthermore, the monitoring of the vibration intensity of the seat, the brainwave intensity of the person being tested on the seat, and the vibration perception intensity includes the following steps:

[0069] The second and third vibration signals of the corresponding areas of the seat are tested using preset seat cushion and backrest sensors;

[0070] The brainwave signals of the person being tested, located on the seat, are monitored using a pre-set brainwave sensor.

[0072] The brainwave intensity is obtained based on the brainwave signal;

[0073] The vibration intensity is obtained based on the second vibration signal, the third vibration signal, and the electroencephalogram (EEG) signal.

[0074] Furthermore, the method also includes the following steps:

[0075] The vibration signal emitted by the exciter is monitored using a preset seat vibration sensor;

[0076] The vibration signal is compared with the vibration control command to obtain vibration error information.

[0077] Furthermore, the method also includes the following steps:

[0078] Based on the vibration error information, the vibration of the exciter is adjusted.

[0079] Furthermore, the method also includes the following steps:

[0080] Based on the vibration relationship function, the target seat vibration of the target vehicle is set.

[0081] Furthermore, the method also includes the following steps:

[0082] Based on the seat vibration target, the design of the target vehicle is optimized.

[0083] It should be noted that the experimental apparatus upon which the technical solutions of this application rely is shown in the accompanying drawings. Figure 2 As shown, Figure 2 In this system, device 1 is an EEG sensor, device 2 is a passenger car seat, device 3 is a seat back sensor, device 4 is a seat cushion sensor, device 5 is a vibrator, device 6 is a control computer, and device 7 is a seat rail vibration sensor. The signal from the seat rail vibration sensor 7 serves as the feedback signal for the control computer 6, detecting whether the output signal meets the requirements.

[0084] The test apparatus is as follows Figure 2 After installation, the tester sits on the passenger car seat 2, and the control computer 6 controls the operation of the vibrator 5 to emit a signal of the corresponding frequency. The frequency test range is 0-50Hz, with an interval of 1Hz. The vibrator 5 can be excited in one direction or simultaneously in the X, Y, and Z directions. The seat rail vibration sensor 7 tests the excitation signal emitted by the vibrator 5 and feeds the signal back to the control computer 6 so that the signal emitted by the vibrator 5 meets the test requirements.

[0085] The seat back sensor 3 and seat cushion sensor 4 respectively test the vibration signals under different excitation signals from the vibrator 5. Simultaneously, the tester's EEG sensor 1 records the tester's feedback on the vibration signals. The tester also needs to provide a subjective evaluation of the different vibrations. The subjective evaluation score is 1-10 points, with intervals of 0.5 points, and 6 points is passing. A higher score indicates less seat vibration and a better subjective experience.

[0086] The excitation input to the vibrator 5 is calculated according to B = A + 3K (dB), where B is the vibration magnitude of the vibrator 5, A is the initial reference vibration value, and some models use -18dB (m / s2)@25Hz as the reference vibration value, K = 0, 1, 2...

[0087] Based on subjective evaluations or tests conducted by external equipment, including EEG, seat cushion sensors, and backrest sensors, scores are obtained to assess the human body's response to different levels of vibration in the chair. The method involves using the intensity of specific frequency bands of EEG to reflect the evaluator's intuitive perception of vibration intensity, the subjective evaluation score to reflect the evaluator's preference for the vibration, and the sensors to record the actual vibration magnitude. By combining EEG and subjective evaluation, and testing a series of evaluators (at least 10 people) while ensuring consistent posture and weight, the correlation between EEG magnitude and subjective evaluation results is obtained (referred to as Correlation 1). For example, EEG magnitude can be divided into 10 levels, from 1 to 10, corresponding to subjective evaluation scores of 1 to 10. A stronger EEG signal should correspond to a lower subjective evaluation score, and the two should have a linear relationship. This prevents evaluators from making evaluations that deviate significantly from actual brain activity. Data from individuals whose results do not exhibit a linear relationship should be discarded. A correspondence can be established between the objective test results and Correlation 1. For example, if the objective test reaches -3dB, Correlation 1 indicates that the vibration is just barely received, the subjective evaluation is 6 points, and the EEG intensity is moderate. As the vibration increases, the subjective evaluation score decreases, and the EEG intensity increases. A correlation function can be formed between these three factors. The form of the correlation function can be KZ = AX + B*(10-Y), where K, A, and B are constants, X is the subjective evaluation score, Y is the EEG intensity score, and Z is the objective test magnitude. The functional relationship between subjective evaluation and objective test shown in the above formula can be obtained at different frequencies.

[0088] This functional relationship can help engineers set vibration targets for seats in different car models. For example, for cars priced below 100,000 yuan, the target only needs to be set to an EEG intensity of 5 points, with a subjective evaluation of 5 points corresponding to the objective test result; for cars priced between 100,000 and 150,000 yuan, the target only needs to be set to an EEG intensity of 4 points, with a subjective evaluation of 6 points corresponding to the objective test result; and for cars priced between 150,000 and 200,000 yuan, the target needs to be set to "good", that is, an EEG intensity of 3 points, with a subjective evaluation of 7 points corresponding to the objective test result, and so on. At the same time, by referring to the size of the seat cushion sensor and backrest sensor, it can help seat developers develop seats that meet the requirements of OEMs.

[0089] Based on the above technical solution, the specific implementation process of this application embodiment is as follows:

[0090] Step 1: The control computer 6 controls the vibrator 5 to send out vibration signals. The seat rail sensor 7 receives the vibration signals and feeds them back to the control computer, so that the output vibration signal meets the test requirements.

[0091] Step 2: The seat cushion sensor 4 and the seat back sensor 3 test the magnitude of the vibration signal, while the EEG sensor 1 receives changes in the human brain's electrical activity. The person being tested also makes a subjective evaluation of the vibration signal.

[0092] Step 3: Repeat steps 1 and 2 to obtain the seat vibration level under different ratings from the testers, and establish a correlation equation between the vibration signal magnitude and the subjective evaluation.

[0093] Step 4: Have different testers repeat steps 1, 2, and 3. Through big data analysis, determine the seat vibration level under different scores, and then use this parameter to set seat vibration targets for different vehicle classes.

[0095] The vibrator, which is pre-installed on the seat, emits vibrations in response to vibration control commands;

[0096] A vibration monitoring module is used to monitor and obtain the vibration intensity of the seat, the brainwave intensity of the person being tested on the seat, and the vibration perception intensity.

[0097] The vibration relationship acquisition module is used to construct a vibration relationship function based on the vibration intensity of the seat corresponding to different vibration control commands, as well as the EEG intensity and vibration perception intensity of different test subjects located on the seat.

[0098] The vibration monitoring module includes:

[0099] A cushion sensor is used to monitor a second vibration signal in the cushion area of ​​the seat;

[0100] A backrest sensor is used to monitor a third vibration signal in the backrest area of ​​the seat;

[0101] An electroencephalogram (EEG) sensor is used to monitor the EEG signals of a person being tested while seated in the chair.

[0104] The vibration sensing intensity receiving submodule is used to receive the vibration sensing intensity based on the second vibration signal, the third vibration signal, and the electroencephalogram signal.

[0105] In this embodiment of the application, a seat vibration performance target is obtained, and a target value is set for the seat vibration of different models to prevent the seat vibration target from being set too strict or too lenient. This ensures that the mass-produced models are competitive in the market while also reducing R&D and manufacturing costs.

[0106] In addition, it can help test the vibration isolation performance of the seat, which can help with the positive development of the seat.

[0107] Furthermore, the device also includes:
