DETAILED DESCRIPTION
[0018] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0019] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be practiced without the specific details; obviously, the embodiments in the description are only a part of the embodiments of the present disclosure, not all the embodiments.
[0020] Figure 1 is a step flow chart of an automobile seat adjusting method provided by the present disclosure, referring to Figure 1 The present disclosure provides an automobile seat adjusting method, comprising: Step S100, acquiring vehicle information and human body pressure information, wherein the vehicle information comprises vehicle speed, steering angle and lateral acceleration; Step S200, calculating the airbag target pressure based on the vehicle information and the human body pressure information; Step S300, comparing the airbag current pressure and the airbag target pressure; When the airbag current pressure and the airbag target pressure are different, step S400 is executed, adjusting the airbag based on the airbag target pressure.
[0021] Specifically, the automobile seat adjusting method provided by the embodiments of the present disclosure is applicable to an automobile seat, referring to Figure 2 , Figure 2This is a structural schematic diagram of a car seat provided in this disclosure. The car seat is equipped with multiple sets of airbags to provide support and comfort for the driver and passengers. Optionally, the car seat includes shoulder positions 1 and 2, lumbar positions 3 and 4, and leg positions 5 and 6. Shoulder positions 1 and 2 are equipped with shoulder airbags, lumbar positions 3 and 4 are equipped with lumbar airbags, and leg positions 5 and 6 are equipped with leg airbags. Optionally, each set of airbags includes multiple small airbags, allowing the airbags to better conform to the user's body and improve comfort. Optionally, the shoulder airbags can be small airbags measuring 180×120mm, with each small airbag placed parallel to the others, with a spacing of 10-15mm between adjacent small airbags, and the maximum height of each small airbag exceeding 55mm, to increase the coverage of the shoulder airbags, accommodate users with different shoulder widths, and ensure that the adjustment of each small airbag does not affect the others. Optionally, the lumbar airbags can be small airbags measuring 210×110mm, with each airbag horizontally overlapping the others. The overlap width between adjacent airbags is 35-50mm, resulting in a more linear adjustment of the lumbar airbags and preventing excessive discomfort in the lower back during adjustment. Alternatively, the leg airbags can be small airbags measuring 230×90mm, with each airbag vertically overlapping the others. The overlap width between adjacent airbags is 20-30mm, avoiding interference with the surrounding frame and foam structure.
[0022] Optionally, the airbag may be made of TPU material. Of course, in other embodiments of this disclosure, the airbag may also be made of other materials.
[0023] Optional, see reference Figure 3 , Figure 3 This is a schematic diagram of the position of a car seat provided in this disclosure. The car seat is equipped with multiple pressure sensors. Figure 3 Pressure sensors are installed at positions 7 and 8 in the middle, that is, near the spine and shoulders. Figure 3 Pressure sensors are located at positions 9 and 10 in the middle of the seat, specifically at the mid-lumbar region. Figure 3 Pressure sensors are installed at positions 11 and 12, that is, in the middle of the thigh. Optionally, the pressure sensors should be placed away from highly elastic materials such as foam.
[0024] Optionally, each small air bag in each group of air bags is arranged corresponding to each sub-pressure sensor in a group of pressure sensors. The sensitivity of each sub-pressure sensor in each group of pressure sensors can be set differently. Optionally, since the closer to the middle position of positions 7 and 8, the stronger the pressure received, in the pressure sensor corresponding to the shoulder air bag, the closer to the middle position of positions 7 and 8, the lower the sensitivity of each sub-pressure sensor, so as to reduce the influence of noise data on the air bag. Optionally, since the farther away from the middle position of positions 9 and 10, the stronger the pressure received, in the pressure sensor corresponding to the shoulder air bag, the farther away from the middle position of positions 9 and 10, the lower the sensitivity of each sub-pressure sensor, so as to reduce the influence of noise data on the air bag. Optionally, since the farther away from the middle position of positions 11 and 12, the stronger the pressure received, in the pressure sensor corresponding to the shoulder air bag, the farther away from the middle position of positions 11 and 12, the lower the sensitivity of each sub-pressure sensor, so as to reduce the influence of noise data on the air bag.
[0025] In the automobile seat adjusting method provided by the embodiments of the present disclosure, vehicle information and human body pressure information are first acquired, wherein the vehicle information includes vehicle speed, steering angle and lateral acceleration. The human body pressure information can be acquired by a pressure sensor. The air bag target pressure is calculated based on the vehicle information and the human body pressure information. The air bag is adjusted based on the air bag target pressure when the current air bag pressure is different from the air bag target pressure. That is, the air bag can be adjusted based on the air bag target pressure generated by the human body pressure information, the vehicle speed, the steering angle and the lateral acceleration, so that the adjustment of the air bag takes into account the human body pressure information, the vehicle speed, the steering angle and the lateral acceleration, and the seat wrapping can be adaptively adjusted according to the user's body characteristics and the driving environment, thereby improving the user's driving experience.
[0026] Optionally, the vehicle information and the human body pressure information can be acquired at intervals of a first time. The first time is a buffer time for the air pump adjustment. Since the air bag is adjusted based on the air bag target pressure by the air pump, the air pump load is prevented from being overloaded, which is beneficial to reduce energy consumption. It should be noted that the first time can be set according to actual needs, and for example, it can be 200 ms, which will not be described herein again.
[0027] Optionally, before calculating the airbag target pressure based on the vehicle information and the human body pressure information, the human body pressure information and the vehicle information are compared with a calibration interval. When the human body pressure information and the vehicle information are located in the calibration interval, the airbag target pressure is calculated based on the vehicle information and the human body pressure information. When the human body pressure information and the vehicle information are not located in the calibration interval, the vehicle information and the human body pressure information are reacquired at intervals of a first time. The calibration interval is a calibration data of each point based on comfort, which can be adjusted according to foaming and face cover. The parameters of each automobile seat are different, and the calibration interval needs to be calibrated, and different body types are needed as sample parameters in the calibration process. Because it involves subjective feeling, the calibration data is used as a sample library. When the human body pressure information and the vehicle information are located in the calibration interval, the airbag target pressure is calculated based on the vehicle information and the human body pressure information, which can filter out abnormal data beyond the comfort range, and ensure that the target pressure calculated subsequently is always within the user's subjective acceptance range. At the same time, when the pressure sensor detects an abnormally high pressure (such as instantaneous concentrated pressure caused by passenger movement or seat inclination) or vehicle abnormal vibration, it will not trigger adjustment immediately, but will reacquire data to avoid false action caused by transient interference.
[0028] Optionally, after obtaining the vehicle information and the human body pressure information, the vehicle information and the human body pressure information can be filtered. Optionally, the median filtering can be used for filtering. Because the steering angle of the steering wheel and the lateral acceleration of the vehicle will have parameter jitter, it is necessary to filter them. The steering angle filtering logic can adopt a sampling period to determine that the value within 20 ms remains unchanged. The value of this 20 ms is the effective value. If it is in a fluctuation state and the effective value, the previous state value is used as the reference. If the lateral acceleration is in a fluctuation state, and the median value of the fluctuation value is less than the data detection threshold value of the lateral acceleration, the previous state value is maintained. If it is higher, the median value is used as the state lateral acceleration value, to avoid false triggering of the threshold value of the lateral acceleration speed value.
[0029] In some optional embodiments, calculating the airbag target pressure based on the vehicle information and the human body pressure information includes: calculating an airbag basic pressure based on the human body pressure information; adjusting the proportion of the airbag basic pressure, a steering angle compensation value and a lateral acceleration compensation value in the airbag target pressure based on the vehicle information, wherein the steering angle compensation value is calibrated according to the steering angle, and the lateral acceleration compensation value is calibrated according to the lateral acceleration.
[0030] Specifically, when calculating the airbag target pressure based on the vehicle information and the human body pressure information, the airbag base pressure can be calculated based on the human body pressure information, and the proportion of the airbag base pressure, the steering angle compensation value and the lateral acceleration compensation value in the airbag target pressure can be adjusted based on the vehicle information. The airbag target pressure is adjusted by the airbag base pressure, so that the airbag can be adjusted according to the body characteristics of the user. Both the steering angle of the vehicle and the lateral acceleration will affect the wrap of the seat to the user. The steering angle compensation value can be calibrated based on the steering angle of the vehicle, and the steering angle compensation value is used to compensate the airbag target pressure when the vehicle has a certain threshold steering angle, so as to alleviate the influence of the steering angle of the vehicle on the wrap of the seat to the user. Similarly, the lateral acceleration compensation value can be calibrated based on the lateral acceleration of the vehicle, and the lateral acceleration compensation value is used to compensate the airbag target pressure when the vehicle has a certain threshold lateral acceleration, so as to alleviate the influence of the lateral acceleration of the vehicle on the wrap of the seat to the user. That is, the airbag target pressure is calculated by whether to adopt the steering angle compensation value and the lateral acceleration compensation value to compensate the airbag base pressure, and the proportion of the steering angle compensation value and the lateral acceleration compensation value to compensate the airbag base pressure to calculate the airbag target pressure, so as to adapt to the adjustment of the airbag in different vehicle environments. Thus, the wrap of the seat can be self-adaptively adjusted according to the body characteristics of the user and the vehicle environment, and the riding experience of the user is improved.
[0031] Optionally, when the lateral acceleration compensation value is calibrated, the vehicle body weight and the chassis suspension can be used for calibration, and the calibration road conditions can include city, town and suburb, and mountain area.
[0032] In some optional embodiments, adjusting the proportion of the airbag base pressure, the steering angle compensation value and the lateral acceleration compensation value in the airbag target pressure based on the vehicle information comprises: When the steering angle is less than or equal to the first threshold value and the lateral acceleration is less than or equal to the second threshold value, the airbag target pressure is equal to the airbag base pressure; When the steering angle is greater than the first threshold value, the proportion of the steering angle compensation value in at least one airbag target pressure is greater than 0; When the lateral acceleration is greater than the second threshold value, the proportion of the lateral acceleration compensation value in at least one airbag target pressure is greater than 0.
[0033] Specifically, when the steering angle is less than or equal to the first threshold value and the lateral acceleration is less than or equal to the second threshold value, that is, the steering angle is small and the lateral acceleration is small, the sensitivity of the pressure sensor is normal, and the airbag base pressure can be directly used as the airbag target pressure.
[0034] When the steering angle is greater than the first threshold value, that is, the steering angle is large, the data collected by the partial pressure sensor is affected, and the corrected airbag target pressure is obtained by compensating the airbag basic pressure by the steering angle compensation value, so as to improve the accuracy of airbag adjustment and improve the user's riding experience.
[0035] When the lateral acceleration is greater than the second threshold value, that is, the lateral acceleration is large, the data collected by the partial pressure sensor is affected, and the corrected airbag target pressure is obtained by compensating the airbag basic pressure by the lateral acceleration compensation value, so as to improve the accuracy of airbag adjustment and improve the user's riding experience.
[0036] It should be noted that the first threshold value and the second threshold value can be set according to actual needs, and the present disclosure does not make specific limitations thereto.
[0037] In some optional embodiments, the proportion of the airbag basic pressure, the steering angle compensation value and the lateral acceleration compensation value in the airbag target pressure based on the vehicle information also includes: When the steering angle is greater than the first threshold value and the vehicle speed is less than or equal to the third threshold value, the proportion of the steering angle compensation value in at least one airbag target pressure is a1; When the steering angle is greater than the first threshold value and the vehicle speed is greater than the third threshold value, the proportion of the steering angle compensation value in the airbag target pressure is a2; Wherein, a1
[0038] Specifically, when the steering angle is greater than the first threshold value and the vehicle speed is less than or equal to the third threshold value, that is, when the steering angle is large and the vehicle speed is small, the proportion of the steering angle compensation value in at least one airbag target pressure is a1, when the steering angle is large and the vehicle speed is large, the proportion of the steering angle compensation value in the airbag target pressure is a2, and a1
[0039] In some optional embodiments, the proportion of the airbag basic pressure, the steering angle compensation value and the lateral acceleration compensation value in the airbag target pressure based on the vehicle information also includes: When the lateral acceleration is greater than the second threshold value and the vehicle speed is less than or equal to the third threshold value, the proportion of the lateral acceleration compensation value in at least one airbag target pressure is b1; When the lateral acceleration is greater than the second threshold value and the vehicle speed is greater than the third threshold value, the proportion of the lateral acceleration compensation value in the airbag target pressure is b2; wherein, b1
[0040] Specifically, when the lateral acceleration is greater than the second threshold value and the vehicle speed is less than or equal to the third threshold value, that is, when the lateral acceleration is relatively large and the vehicle speed is relatively small, the proportion of the lateral acceleration compensation value in the target airbag pressure is b1, and when the lateral acceleration is relatively large and the vehicle speed is relatively large, the proportion of the lateral acceleration compensation value in the target airbag pressure is b2, b1 < b2. That is, when the lateral acceleration is relatively large, the centrifugal force generated by the vehicle body is relatively large when the vehicle is running at a high speed, so the proportion of the lateral acceleration compensation value in the target airbag pressure needs to be increased, so as to further correct the target airbag pressure, improve the accuracy of airbag adjustment, and improve the user's riding experience.
[0041] It should be noted that the third threshold value can be set according to actual needs. For example, the third threshold value can be 70 km / h, and the present disclosure does not make specific limitations thereto.
[0042] In some embodiments, the target airbag pressure includes a shoulder airbag target pressure, a waist airbag target pressure, and a leg airbag target pressure. Adjusting the proportions of the airbag basic pressure, the steering angle compensation value, and the lateral acceleration compensation value in the target airbag pressure based on the vehicle information further includes: Adjusting the proportions of the airbag basic pressure, the steering angle compensation value, and the lateral acceleration compensation value in the shoulder airbag target pressure, the waist airbag target pressure, and the leg airbag target pressure based on the vehicle information, respectively.
[0043] Specifically, the target airbag pressure includes a shoulder airbag target pressure, a waist airbag target pressure, and a leg airbag target pressure. In different vehicle environments, different parts of the human body are affected differently. Therefore, when adjusting the proportions of the airbag basic pressure, the steering angle compensation value, and the lateral acceleration compensation value in the target airbag pressure based on the vehicle information, the proportions of the airbag basic pressure, the steering angle compensation value, and the lateral acceleration compensation value in the shoulder airbag target pressure, the waist airbag target pressure, and the leg airbag target pressure are adjusted based on the vehicle information, respectively. Thus, the airbags of different parts can be adjusted specifically according to the vehicle information, thereby improving the user's riding experience.
[0044] In some optional embodiments, when the steering angle is greater than the first threshold value, the proportions of the steering angle compensation value in at least two of the shoulder airbag target pressure, the waist airbag target pressure, and the leg airbag target pressure are different. When the lateral acceleration is greater than the second threshold value, the proportions of the lateral acceleration compensation value in at least two of the shoulder airbag target pressure, the waist airbag target pressure, and the leg airbag target pressure are different.
[0045] Specifically, when the steering angle is greater than the first threshold, i.e., the steering angle is large, the shoulder, waist and leg of the human body are affected differently, and the proportion of the steering angle compensation value in at least two of the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure is different, i.e., the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure can be adjusted accordingly, thereby improving the user's riding experience.
[0046] When the lateral acceleration is greater than the second threshold, i.e., the lateral acceleration is large, the shoulder, waist and leg of the human body are affected differently, and the proportion of the lateral acceleration compensation value in at least two of the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure is different, i.e., the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure can be adjusted accordingly, thereby improving the user's riding experience.
[0047] For example, when the vehicle speed is low (<30km / h) and medium (<70km / h): When the steering angle is small and the vehicle lateral acceleration is small, the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure are all the corresponding air bag basic pressure; When the steering angle is large and the vehicle lateral acceleration is small, the shoulder air bag target pressure = 0.8 x air bag basic pressure + 0.2 x steering angle compensation value, and the waist air bag target pressure and the leg air bag target pressure are all the corresponding air bag basic pressure; When the steering angle is large and the vehicle lateral acceleration is large, the shoulder air bag target pressure = 0.6 x air bag basic pressure + 0.2 x steering angle compensation value + 0.2 x lateral acceleration compensation value, the waist air bag target pressure = 0.7 x air bag basic pressure + 0.3 x steering angle compensation value + 0.1 x lateral acceleration compensation value, and the leg air bag target pressure is the corresponding air bag basic pressure.
[0048] For high speed (>70km / h) state: When the steering angle is small and the vehicle lateral acceleration is small, the shoulder air bag target pressure, the waist air bag target pressure and the leg air bag target pressure are all the corresponding air bag basic pressure; When the steering angle is large and the vehicle lateral acceleration is small, the shoulder air bag target pressure = 0.5 x air bag basic pressure + 0.5 x steering angle compensation value, the waist air bag target pressure = 0.6 x air bag basic pressure + 0.4 x steering angle compensation value, and the leg air bag target pressure = 0.8 x air bag basic pressure + 0.2 x steering angle compensation value; The turning angle is large, the vehicle lateral acceleration is large, the shoulder air bag target pressure = 0.3 x air bag basic pressure + 0.4 x turning angle compensation value + 0.3 x lateral acceleration compensation value, the waist air bag target pressure = 0.4 x air bag basic pressure + 0.3 x turning angle compensation value + 0.3 x lateral acceleration compensation value, and the leg air bag target pressure = 0.5 x air bag basic pressure + 0.3 x turning angle compensation value + 0.3 x lateral acceleration compensation value.
[0049] It should be noted that the above only exemplarily shows a method for adjusting an automobile seat, and in other embodiments of the present disclosure, other setting modes can be adopted according to actual needs, which will not be described one by one herein.
[0050] In some optional embodiments, calculating the air bag basic pressure based on the human body pressure information comprises: calculating the optimal parameter value based on the air bag actual pressure of each sampling point, the air bag basic pressure of each sampling point, and the number of sampling points; calculating the air bag basic pressure based on the human body pressure information and the optimal parameter value.
[0051] Specifically, calculating the air bag basic pressure based on the human body pressure information comprises: calculating a fitting function based on a loss function, wherein the loss function is , is the air bag actual pressure of each sampling point, is the air bag basic pressure of each sampling point, and m is the number of sampling points; calculating the air bag basic pressure based on the human body pressure information through the fitting function, wherein the fitting function is , is the air bag basic pressure, is the human body pressure information.
[0052] Specifically, the fitting function is used to calculate the corresponding air bag basic pressure under the human body pressure information, and the loss function can be solved by minimizing the loss function to obtain the optimal parameter , so that the fitting function is closer to the actual data, that is, the loss function is used to compensate the fitting function, so that the fitting function is more linear, so as to improve the accuracy of the air bag basic pressure calculation.
[0053] Optionally, the loss function and the fitting function can be calibrated for people of different body shapes, and when a user is seated, the closest loss function and fitting function are dispatched according to the human body pressure information.
