[0027] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. At the same time, it should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0029] Currently, commercial vehicle drivers are required to drive for extended periods of time. Factors such as prolonged sitting, incorrect sitting posture, and excessively high or low cabin temperatures can easily lead to driver fatigue and cause traffic accidents. Furthermore, existing commercial vehicle seats only provide basic comfort for drivers and lack features such as occupant pressure recognition, ride duration, and temperature sensing. Long periods of sitting in commercial vehicle seats can lead to fatigue and physical problems such as lower back pain and leg soreness. Furthermore, prolonged fatigue can easily lead to traffic accidents, necessitating improvements.

[0030] To address the above-mentioned issues, a prior art vehicle seat employs multiple air bags and heating devices in the seat cushion and backrest areas to adjust the seat's operating state. However, since this prior art solution fails to differentiate between different vehicle driving states when adjusting the seat's operating state to mitigate the varying impacts of the seat on the driver, it can still easily lead to driver fatigue while the vehicle is in motion. Vehicle driving states include, for example, stable, steady, tilted, and impacted states.

[0031] Based on the above problems, Figure 1 As shown, the first embodiment of the present invention provides a method for automatically adjusting a vehicle seat. It should be noted that the method of the present invention is not limited to the method of the vehicle seat. Figure 1 The process sequence shown is limited. In actual operation, the vehicle seat automatic adjustment method includes:

[0032] S1. Acquire the current driving state of the vehicle, which includes a stable state, a tilted state, an impact state, and a collision state.

[0033] In this step, the purpose of the present invention obtaining the current driving state is to obtain the current state of the seat, thereby obtaining the current state of the driver on the seat, so that the present invention can adjust the state of the seat in a timely and accurate manner.

[0034] In this step, a stable state refers to the vehicle being in a normal driving state, such as a constant speed of 80 km / h or normal acceleration / deceleration; a tilted state refers to the vehicle being in a sideways tilt; an impact state refers to the vehicle being in a vertically bumpy, upward, or downward impact state; and a collision state refers to the vehicle being in an emergency braking state or a collision state. In actual operation, if the vehicle is stationary (e.g., parked), the present invention may treat the vehicle as being in a stable state, meaning that the seat operates in a stable mode.

[0035] Preferably, in order to further enhance the safety performance of the present invention and improve the driver's acceptance of the new seat function, the present invention may further perform the following steps before executing step S1: issuing a command reminder (such as a voice reminder) to the driver to inform the vehicle that the working state of the seat will be adjusted, and then executing the above step S1 after obtaining the driver's consent and authorization. In this way, the driver can adjust the working state of the seat according to their own needs (such as seat heating), thereby saving fuel when the vehicle is in a fuel-starved state, and allowing the driver to decide whether to activate the seat adjustment method of the present invention according to their needs.

[0036] S2. Determine a current seat adjustment mode based on the current driving state, where the current adjustment mode includes a stable mode, a tilt mode, an impact mode, and a collision mode;

[0037] In this step, the steps of determining the current adjustment mode of the seat include: S21, if the current driving state of the vehicle is a stable state, the seat operates in a stable mode; S22, if the current driving state of the vehicle is a tilted state, the seat operates in a tilted mode; S23, if the current driving state of the vehicle is an impact state, the seat operates in an impact mode; S24, if the current driving state of the vehicle is a collision state, the seat operates in a collision mode.

[0038] S3. obtaining the current sitting time of the driver in the seat through a preset time sensor, obtaining the current body temperature of the driver through a preset temperature sensor, and obtaining the current body pressure of the driver through a preset pressure sensor;

[0039] In this step, the time sensor can be arranged on the seat or at other locations on the vehicle (such as the steering wheel or engine), and the temperature sensor and pressure sensor can be arranged in the seat cushion area and backrest area of the seat. Among them, only one temperature sensor is required on the seat cushion area and backrest area of the seat respectively, but multiple pressure sensors are required on the seat cushion area and backrest area of the seat respectively.

[0040] In this embodiment, there is a one-to-one correspondence between the seat pressure sensors and the airbags, meaning that a pressure sensor is installed at the corresponding position of each airbag (the end of the airbag closest to the driver). Preferably, this embodiment can be implemented by placing a pressure monitoring blanket on the seat, with the pressure monitoring blanket being equipped with a pressure sensor corresponding to the position of each airbag on the seat, thus making the present invention more convenient to use.

[0041] S4. Adjust the working state of the seat according to the current riding time, current body temperature and current body pressure according to the current adjustment mode to reduce the driver's fatigue.

[0042] In this step, adjusting the working state of the seat includes:

[0043] S41. Providing a preset voice reminder to the driver based on the current ride duration;

[0044] In this step, the present invention can adopt different voice reminder methods for different current riding times. For example, if the current riding time does not exceed 1 hour, the voice reminder can be set to pay attention to driving safety; if the current riding time is 1 to 3 hours, the voice reminder can be set to pay attention to fatigue driving + pay attention to safety; if the current riding time exceeds 3 hours, the voice reminder can be set to stop and rest for a while (such as a quarter of an hour) for driving safety.

[0045] Preferably, the present invention can further set a preset driving time (such as 5 hours). If the current riding time is greater than the preset driving time, the vehicle seat will be forced to enter an automatic adjustment state, or after obtaining the driver's consent and authorization, the vehicle will be forced to enter a parking state to allow the driver to rest for a period of time, thereby reducing the driver's fatigue.

[0046] S42, adjusting the seat to a preset rated temperature according to the current body temperature;

[0047] In this step, when the current body temperature is greater than the preset maximum rated temperature, the seat is cooled by the preset ventilation equipment to adjust the seat to the preset rated temperature; when the current body temperature is in the preset temperature range, the seat is allowed to continue to maintain the current state; when the current body temperature is lower than the preset minimum rated temperature, the seat is heated by the preset heating equipment to adjust the seat to the preset rated temperature.

[0048] S43. Adjust the inflation and deflation states of the air bags in the seat according to the current body pressure and the current adjustment mode of the seat.

[0049] In this step, the steps of adjusting the inflation and deflation state of the air bag in the seat include:

[0050] S431: If the seat is operating in a stable mode, maintain the current state of each air bag in the seat;

[0051] In this step, the present invention further includes adjusting the seat to a height corresponding to the current body pressure. This allows the present invention to reduce driver fatigue by adjusting the seat height while maintaining a stable vehicle. In practice, the seat height adjustment step can be performed only after obtaining the driver's authorization, thereby enhancing safety.

[0052] Preferably, in order to further increase the safety performance of the seat, the present invention can automatically adjust the backrest and seat cushion profile according to the pressure distribution in the seat cushion area and the backrest area, and the fit between the driver and the seat when the current riding time is greater than a preset driving time (such as 3 hours), so that the seat airbag can make adaptive adjustments when the vehicle moves in the longitudinal, vertical and horizontal directions to better support the human body. Specifically: through the pressure sensor blanket on the seat fabric (arranged with multiple pressure sensors), the pressure of the human body after riding is identified, and the regional distribution of the pressure sensor blanket corresponds to the distribution position of the airbag on the seat.

[0053] S432: If the seat is operating in the reclining mode, obtain the pressure difference of each pressure sensor on the seat at a preset interval, and adjust the inflation and deflation status of each air bag in the seat according to the pressure difference;

[0054] In this step, when the seat is in tilt mode, that is, the vehicle is in a roll state, the present invention can determine the roll direction of the vehicle based on the vehicle body suspension displacement signal. When the vehicle tilts to the left, the left airbags of the seat cushion and backrest are inflated to provide effective support to the driver's body. When the vehicle tilts to the right, the right airbags of the seat cushion and backrest are inflated to provide effective support to the driver's body. Specifically, the steps include:

[0055] S4321. If the current adjustment mode of the seat is the tilt mode, obtain the current pressure value of each pressure sensor on the seat; S4322. Obtain the tilt pressure value of each pressure sensor on the seat again according to the preset interval time; S4323. Calculate the pressure difference of each sensor according to the current pressure value and the tilt pressure value; S4324. Obtain the position of the pressure sensor on the seat where the pressure difference exceeds the preset pressure value, and record it as the position to be adjusted; S4325. Adjust the inflation and deflation status of the air bags on the seat and the position to be adjusted according to the position to be adjusted.

[0056] In actual operation, the position to be adjusted is also the position on the seat that needs to be inflated and deflated. In this way, the present invention can accurately control the inflation and deflation of the air bag only according to the pressure difference, thereby further reducing the driver's fatigue and improving the safety performance of the vehicle.

[0057] S433: If the seat is operated in the collision mode, deflate each air bag in the seat;

[0058] In this step, when the seat is operating in collision mode, that is, the vehicle is in emergency braking or collision state, the present invention can deflate the airbags in the seat cushion and backrest areas according to the AEBS signal when the vehicle is emergency braked or collides, so as to provide the driver with more space, reduce passenger injuries, and improve the safety performance of the present invention.

[0059] S434. If the seat is operated in impact mode, obtain the current impact state of the vehicle and adjust the inflation and deflation states of each air bag in the seat according to the impact state, wherein the current impact state includes an upward impact state and a downward impact state.

[0060] In this step, when the seat is operated in the impact mode, that is, the vehicle is in a vertical bumping state or a vertical impact state, the present invention can control the inflation and deflation states of each air bag according to the vehicle body suspension displacement signal. During the downward impact movement, the air bags in the seat cushion area are deflated to reduce the impact; during the upward impact movement, the air bags in the seat cushion area are inflated to support the human body. Specifically, it includes: S4341, if the current impact state is a downward impact state, the air bags in the seat cushion area of the seat are in a deflated state; S4342, if the current impact state is an upward impact state, the air bags in the seat cushion area are in an inflated state.

[0061] During actual operation, the layout of the pressure sensor on the pressure test blanket can be adaptively adjusted according to the requirements of the fabric sewing assembly, and the air bag pressure value range can be adjusted as follows: use the 95% dummy in the SAE standard, place it on the seat to conduct human riding pressure tests 3 times, and then find a real person who meets the 95% human body standard to experience the test 3 times. Based on the above 6 test results, take the average of the maximum and minimum values ​​in each area to determine the pressure range of the air bag.

[0062] In actual operation, the present invention also includes a method for controlling the accuracy of inflation and deflation volume: the single inflation and deflation volume q of the main inflation valve is tested, and the single inflation and deflation volume p and the change value △p of the test pressure under the 95% dummy and real person riding conditions are used to determine the relationship between the inflation and deflation volume q and △p, so as to calibrate the single inflation and deflation volume q and ensure that the inflation and deflation meet the pressure range.

[0063] In actual operation, the present invention is to more clearly illustrate the corresponding relationship between the arrangement position of the air bag on the seat and the comfort human body distribution evaluation diagram, such as Figures 2 and 3 , Figure 2 Marks 1 to 16 are all air bags. Figure 3 Markers 1 to 17 in the figure are different parts of the human body, as follows:

[0064] (1) Principles for airbag distribution in the seat cushion area: Based on the comfort evaluation of human body distribution, airbag size, and seat cushion surface features, the left thigh area 12 corresponds to airbags 5 and 6, and the right thigh area 15 corresponds to airbags 1 and 2; in the middle seating area, thighs 13 and 14 correspond to airbag 3, and buttocks 10 and 11 correspond to airbag 4. Thighs 16 and 17 need to move due to clutch and accelerator operation, and are limited by the curved surface features of the front end of the seat, making it inconvenient to arrange airbags. There is currently no direct corresponding airbag, and airbag 3 can be used for auxiliary adjustment.

[0065] (2) Principles for the distribution of airbags in the backrest area: In addition to the comfort evaluation of human body distribution, airbag size, and seat cushion surface characteristics, since commercial vehicle drivers drive for long periods of time, lumbar support is particularly critical to comfort and driving fatigue. Therefore, the human waist area 6 corresponds to airbags 7 and 8, the human shoulder areas 1 and 2 correspond to airbags 12, 13, and 14, and the back area 4 corresponds to airbag 9. After the human body 7, 8, and 9 are seated, they correspond to the connection between the backrest and the seat cushion in the seat. The airbag layout is limited and is assisted by airbags 7, 10, and 16.

[0066] In actual operation, the present invention can adjust the working state of the seat cushion area and backrest area according to the calibrated corresponding area pressure range and the measured pressure of the human body, as shown in the following table:
