DETAILED DESCRIPTION

[0051] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0052] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0053] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0054] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0055] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0056] According to one embodiment of the present application, a method for adjusting a seat is provided. Figure 1 As shown, the seat adjustment method is applied to a vehicle, comprising:

[0057] Acquiring roll risk information representing a roll risk of the vehicle;

[0058] The seat wings are adjusted according to the roll risk information.

[0059] Specifically, the seat adjustment method is used to adjust the support angle of the seat wing. Figure 3 As shown, the seat wing comprises a cushion wing 402 and a backrest wing 401. By adjusting the support angle of the cushion wing 402 and / or the backrest wing 401, suitable support is provided for the occupant to prevent the occupant from excessively leaning when the vehicle rolls.

[0060] Of course, the seat side wings are not limited to the above embodiments, and the seat side wings may also only include the seat cushion side wings 402 or the backrest side wings 401 , or other forms of side wings.

[0061] Generally, the length of a vehicle is usually greater than its width, so the risk of the vehicle rolling over is high. For example, when a vehicle encounters a slope or turns, it is easy to roll over, causing passengers or objects carried by the vehicle to tilt.

[0062] In this example, by acquiring the roll risk information representing the roll risk of the vehicle and adjusting the seat wings according to the roll risk information, this method can accurately determine whether the body of the occupant is tilted to a large extent and whether the seat wings are needed to support the occupant, thereby making the adjustment of the seat wings more accurate and improving the riding comfort of the occupant.

[0063] Of course, the seat side wings may also provide support for objects carried by the vehicle to improve the stability of the objects.

[0064] In one example, the roll risk information includes a risk parameter;

[0065] The step of adjusting the seat wing according to the roll risk information comprises:

[0066] When the risk parameter is greater than or equal to a set threshold, the seat wing is adjusted.

[0067] In this example, the seat wings are adjusted based on the comparison between the risk parameter and the set threshold. When the risk parameter exceeds the set threshold and the vehicle rolls to a set degree, the seat wings are adjusted, rather than adjusting the seat wings under any conditions. In this way, on the one hand, the timing of seat wing adjustment can be made more accurate; on the other hand, by adjusting the seat wings when the preset conditions are met, energy can be saved.

[0068] In one example, the tilt risk information includes: the tilt angle of the vehicle. The tilt angle can directly represent the angle of vehicle roll. For example, when a vehicle passes through a tilted road or the vehicle load is unbalanced, it is easy to roll. Adjusting the seat wing according to the tilt angle of the vehicle can effectively determine the roll degree of the vehicle, thereby accurately determining the timing of adjusting the seat wing.

[0069] Of course, the risk parameter is not limited to the tilt angle, and those skilled in the art can select it according to actual needs.

[0070] In one example, the roll risk information further includes: at least one of a speed of the vehicle and a steering angle of the vehicle.

[0071] In this example, the seat wings are adjusted according to the vehicle's tilt angle, and at least one of the vehicle's speed and steering angle. The steering angle is the angle at which the vehicle's steering wheel is turned. The vehicle is prone to roll when turning. When the vehicle is driving, the higher the speed of the vehicle, the higher the risk of the vehicle rolling. By comprehensively judging multiple risk parameters, the risk of vehicle rolling can be judged more effectively.

[0072] For example, the seat wings are adjusted according to the vehicle's tilt angle and speed;

[0073] or, based on the steering and lean angles of the vehicle;

[0074] or, based on the vehicle's lean angle, steering angle, and speed;

[0075] Alternatively, the risk parameter includes at least two of the above conditions.

[0076] In one example, when the risk parameter is greater than or equal to a set threshold, the seat wing is adjusted.

[0077] For example, under the condition that the speed of the vehicle is greater than or equal to a speed threshold, and the tilt angle is greater than or equal to an angle threshold, the seat wing is adjusted.

[0078] Alternatively, the seat wing is adjusted under the condition that the vehicle tilt angle is greater than or equal to an angle threshold, and the steering angle is greater than or equal to a turning angle threshold.

[0079] Alternatively, the seat wing is adjusted under the condition that the speed of the vehicle is greater than or equal to a speed threshold, the steering angle is greater than or equal to a steering angle threshold, and the tilt angle is greater than or equal to an angle threshold.

[0080] According to different risk parameters, the method for generating the adjustment parameters of the seat wing may also be a combination of any of the above conditions. Those skilled in the art may select and set the threshold and risk parameter according to actual needs.

[0081] Among them, under the condition that the risk parameter is a combination of speed, tilt angle and steering angle, the judgment of vehicle roll risk is more accurate.

[0082] In one example, the risk parameter includes at least one of the following:

[0083] The risk parameter includes a tilt angle of the vehicle, the set threshold includes an angle threshold, and the angle threshold is 8° to 25°;

[0084] The risk parameter includes the speed of the vehicle, the set threshold includes a speed threshold, and the speed threshold is 20 km / h to 40 km / h;

[0085] The risk parameter includes a steering angle of the vehicle, and the set threshold includes a turning angle threshold, and the turning angle threshold is 5° to 30°.

[0086] In this example, by controlling the range of the set threshold, it is possible to effectively determine whether the seat wing needs to be adjusted, thereby more accurately controlling the timing of adjusting the seat wing.

[0087] Of course, the range of setting the threshold is not limited to the above embodiments, and those skilled in the art can make a selection according to actual needs.

[0088] When the vehicle is moving at a low speed, even if the vehicle tilts, the passengers can adjust their sitting posture in time to adapt to the tilt of the vehicle. When the vehicle is moving at a high speed, the passengers do not have time to adjust their sitting posture. Similarly, when the vehicle is moving at a low speed, if the tilt angle of the vehicle is small, the passengers will not feel a strong sense of discomfort.

[0089] In a specific example, the speed of the vehicle is compared with a speed threshold and the tilt angle of the vehicle is compared with an angle threshold. The speed of the vehicle reaches the speed threshold and the tilt angle reaches the angle threshold as trigger conditions for adjusting the seat wing. When the trigger conditions are met, the seat wing is adjusted. This method can avoid unnecessary seat wing adjustment.

[0090] For example, the speed threshold is 30 km / h and the angle threshold is 10°. When the vehicle is traveling and the speed reaches 30 km / h and the tilt angle reaches 10°, the adjustment parameters of the seat wing are generated to adjust the seat wing.

[0091] If the speed does not reach 30 km / h or the inclination angle does not reach 10°, the seat wings will not be adjusted.

[0092] In a specific example, the vehicle's tilt angle is compared with an angle threshold and the vehicle's steering angle is compared with a turning angle threshold. The vehicle's tilt angle reaching the angle threshold and the steering angle reaching the turning angle threshold are used as trigger conditions for adjusting the seat wing. When the trigger conditions are met, the seat wing adjustment parameters are generated to adjust the seat wing. This method can also avoid unnecessary seat wing adjustment.

[0093] For example, the speed threshold is 8° and the turning angle threshold is 5°. When the vehicle is traveling and the inclination angle of the vehicle reaches 8° and the steering angle reaches 5°, the adjustment parameters of the seat wing are generated to adjust the seat wing.

[0094] If the reclining angle does not reach 8° or the steering angle does not reach 5°, the seat wings are not adjusted.

[0095] In a specific example, the speed of the vehicle is compared with a speed threshold, the tilt angle of the vehicle is compared with an angle threshold, and the steering angle of the vehicle is compared with a turning angle threshold. The speed of the vehicle reaches the speed threshold, the tilt angle reaches the angle threshold, and the steering angle reaches the turning angle threshold as trigger conditions for adjusting the seat wing. When the trigger conditions are met, the adjustment parameters of the seat wing are generated to adjust the seat wing. This method can also avoid unnecessary seat wing adjustment.

[0096] For example, the speed threshold is 20 km / h, the angle threshold is 25°, and the turning angle threshold is 15°. When the vehicle is traveling, the speed of the vehicle reaches 20 km / h, the tilt angle reaches 25°, and the steering angle reaches 15°, the adjustment parameters of the seat wings are generated to adjust the seat wings.

[0097] If the speed does not reach 20 km / h, the tilt angle does not reach 25° or the steering angle does not reach 15°, the seat wings will not be adjusted.

[0098] Of course, the speed threshold, the rotation angle threshold and the angle threshold are not limited to the above embodiments, and those skilled in the art may select them according to actual needs.

[0099] In one example, the set threshold includes a first set threshold and a second set threshold, and the second set threshold is greater than the first set threshold.

[0100] In this example, by setting different threshold values, multiple adjustment parameters can be generated, thereby providing multiple levels of seat wing adjustment to meet the needs of seat wing adjustment in different scenarios. For example, the larger the threshold value, the greater the vehicle roll angle, and a larger adjustment parameter needs to be output to meet the needs of occupant support. Conversely, the smaller the threshold value, the smaller the vehicle roll angle, and a smaller adjustment parameter needs to be output.

[0101] In a specific example, the threshold is set to an angle threshold. The angle threshold includes a first angle threshold and a second angle threshold, and the second angle threshold is greater than the first angle threshold.

[0102] In this example, under the condition that the tilt angle is greater than or equal to the first angle threshold but less than the second angle threshold, a first adjustment parameter is generated to adjust the seat wing.

[0103] Under the condition that the tilt angle is greater than or equal to the second angle threshold, a second adjustment parameter is generated to adjust the seat wing. Since the second angle threshold is greater than the first angle threshold, the second adjustment parameter makes the seat wing adjusted at a larger angle.

[0104] For example, the first angle threshold is 10°, and the second angle threshold is 15°. In this way, the adjustment of the seat wing is provided with two gears, thereby meeting the seat wing adjustment requirements in different scenarios.

[0105] Of course, the set threshold is not limited to two, and those skilled in the art can set the number of the set threshold according to actual needs.

[0106] In one example, adjusting the seat wing includes adjusting at least one of an air pressure of an air bag of the seat and a support angle of the seat wing.

[0107] In this example, the seat wing may be adjusted directly by adjusting the support angle of the seat wing. When the support angle of the seat wing reaches the set support angle, the adjustment is stopped. This adjustment method can accurately adjust the seat wing.

[0108] Alternatively, the seat wing may be indirectly adjusted by adjusting the air pressure of the air bag of the seat wing. For example, the adjustment parameter includes the air pressure of the air bag 311. The greater the air pressure of the air bag 311, the greater the volume of the air bag 311 and the greater the support angle of the seat wing; conversely, the smaller the air pressure of the air bag 311, the smaller the support angle of the seat wing. Indirectly adjusting the support angle of the seat wing by adjusting the air pressure of the air bag 311 makes the operation of adjusting the seat wing easier.

[0109] In one example, adjusting the seat wing according to the roll risk information further includes:

[0110] Under the condition that the risk parameter is less than a set threshold value for a set time period, the seat wing is adjusted to return to the initial position.

[0111] For example, under the condition that the speed of the vehicle is less than a speed threshold and / or the tilt angle is less than an angle threshold for a set time period, the seat wing returns to the initial state.

[0112] For example, the time length is set to 3 seconds. In this example, before the trigger condition is removed, the seat wing remains in the adjusted state. After the trigger condition is met, the seat wing remains in the adjusted state for 3 seconds, and then the seat wing gradually returns to the initial state. For example, the initial state is the state before the seat wing is adjusted or the state when the seat wing reaches a set angle, such as 0°.

[0113] Of course, the seat wing may also be restored to the initial state under the condition that the steering angle of the vehicle is less than the setting time of the turning angle threshold. The setting time is not limited here, and those skilled in the art can set it according to actual needs.

[0114] In one example, before adjusting the seat wing according to the roll risk information, the method further includes: confirming that the seat wing has not reached a target state.

[0115] For example, the current state of the seat wing is obtained, and the current state is compared with the target state corresponding to the adjustment parameter; if the current state does not reach the target state, the seat wing is adjusted. If the current state has reached the target state, the seat wing is not adjusted.

[0116] In this way, it is possible to effectively determine whether the seat wing needs to be adjusted, thus avoiding unnecessary operations.

[0117] The current state of the seat wing may include a current support angle, etc. The target state is a target support angle of the seat wing. When the current support angle does not reach the target support angle, the support angle of the seat wing is increased to reach the target support angle.

[0118] If the current support angle is greater than or equal to the target support angle, it indicates that the seat wing has been adjusted to the correct position. In this case, the seat wing is not adjusted.

[0119] In this way, it is possible to determine whether the seat wing needs to be adjusted based on the comparison between the current state of the seat wing and the target state, thereby improving the accuracy of seat adjustment.

[0120] In a specific example, the current support angle of the seat wing is 30° (for example, relative to the seat cushion or backrest). If the target support angle is 40°, the seat wing is adjusted so that the angle value of the seat wing reaches 40°. If the current support angle is greater than or equal to 40°, it indicates that the seat wing has been adjusted to the right position, and the seat wing does not need to be adjusted under this condition. In this way, over-adjustment of the seat wing can be effectively avoided.

[0121] Alternatively, the current state is the current air pressure of the airbag, and the target state is the target air pressure of the airbag.

[0122] The seat wings are usually adjusted by air bags, and the air pressure can represent the support angle of the seat wings. In this example, by obtaining the current air pressure of the air bag and comparing it with the target air pressure, it is determined whether the seat wings need to be adjusted. It is easier and more accurate to obtain the air pressure of the air bag than to obtain the current support angle of the seat wings, so this method makes the seat wings more accurately adjusted.

[0123] In one example, the target state is a state when the occupant tilt risk meets safety requirements.

[0124] For example, the safety requirement is met when the passenger's tilt angle is less than or equal to a set value. Under this condition, the passenger will not feel uncomfortable due to the tilt, or there is no risk of the passenger tipping over. The set value is, for example, 20° to 45°.

[0125] Of course, the setting value is not limited to the above embodiment, and those skilled in the art can select it according to actual needs.

[0126] In one example, the target state is a state when the target air pressure of the air bag of the seat meets safety requirements.

[0127] For example, when the air pressure of the airbag reaches the set value, the support angle of the seat side wings can meet the support requirements of the occupants to ensure that the occupant's tilt risk meets safety requirements.

[0128] Of course, those skilled in the art can select the set value according to actual needs.

[0129] According to another embodiment of the present application, a seat adjustment device is provided. Figure 2 As shown, the device includes: a processor, the processor is connected to a memory, and the processor is configured to execute a program in the memory to implement the above-mentioned seat adjustment method.

[0130] According to another embodiment of the present application, a seat adjustment system is provided. The system includes the above-mentioned adjustment device and an adjustment unit. The adjustment device controls the adjustment unit to adjust the seat wing. For example, the adjustment device includes a signal acquisition unit 100 and a control unit 200. The signal acquisition unit 100 is used to obtain roll risk information characterizing the roll risk of the vehicle.

[0131] The adjustment unit 300 is used to adjust the seat wing according to the roll risk information.

[0132] For example, the signal acquisition unit 100 includes a speed sensor 103 and an inclination sensor 101. The speed sensor 103 is, for example, a speed sensor 103 in an intelligent integrated power brake system (IPB). The inclination sensor 101 is, for example, an inclination sensor 101 in an electric active suspension system (DI-Suspension, DISUS). The speed sensor 103 is used to acquire the speed of the vehicle. The inclination sensor 101 is used to acquire the inclination angle of the vehicle.

[0133] In other examples, the signal acquisition unit 100 is also used to acquire the steering angle of the steering wheel of the vehicle. For example, the signal acquisition unit 100 also includes a steering angle sensor 102 of the steering wheel in an electric power steering system (EPS). Active adjustment of the seat wing can also be achieved by acquiring the steering angle of the steering wheel.

[0134] The signal acquisition unit 100 is connected to the control unit 200. The control unit 200 is, for example, a vehicle controller of the vehicle or a controller independently provided for the seat adjustment system. The control unit 200 is used to issue tilt risk information. The tilt risk information is as described above.

[0135] The adjustment unit 300 adjusts the seat wing through structures such as an air pressure adjustment structure and a connecting rod adjustment structure.

[0136] The adjustment system of the seat can realize active adjustment of the seat side wings, so as to timely adjust the seat side wings when the vehicle rolls over during driving, so as to adjust the angle of the seat side wings to support the occupants and prevent the occupants from tilting to multiple degrees.

[0137] In an example, Figure 2 As shown, the adjustment unit 300 includes an air bag 311 and a gas supply unit. The air bag 311 is suitable for being connected to the gas supply unit. The air bag 311 is used to adjust the angle of the seat wing.

[0138] For example, the airbag 311 includes a left wing airbag and a right wing airbag. The airbag 311 is supported against the seat wing. The left wing airbag is used to adjust the angle of the seat wing on the left side of the seat. The right wing airbag is used to adjust the angle of the seat wing on the right side of the seat. The gas supply unit is used to supply gas to the airbag 311 to change the volume of the airbag 311. Since the airbag 311 is supported against the seat wing, the angle of the seat wing is changed by changing the volume of the airbag 311.

[0139] The gas supply device includes, for example, an air pump. The air pump is suitable for connecting to the air bag 311. Further, the gas supply device also includes a gas tank, etc. The air pump is connected to the gas tank. The gas tank is suitable for connecting to the air bag 311. The gas tank can be directly connected to the air bag 311 through a pipeline; it can also be indirectly connected to the air bag 311, for example, a valve, a flow meter, a pressure sensing device, etc. are provided on the pipeline. The air pump can be, but is not limited to, an air compressor, a nitrogen compressor, an inert gas compressor, etc.

[0140] In this example, the adjustment unit 300 has a simple structure, a small size, and is easy to install and disassemble.

[0141] In addition, the pneumatic adjustment method is not limited by the distance between the gas supply unit and the air bag 311, and the gas supply unit and the air bag 311 can be installed according to the needs of the spatial position.

[0142] Of course, the adjustment unit 300 is not limited to the above embodiment, and the angle of the seat wing may also be adjusted by using a connecting rod, a worm gear, a lead screw, etc.

[0143] In an example, Figure 2 As shown, the seat adjustment system further includes a pneumatic system controller 309 . The gas supply unit is connected to the air bag 311 via the pneumatic system controller 309 , and the adjustment device controls the air pressure of the air bag 311 by controlling the pneumatic system controller 309 .

[0144] The pneumatic system controller 309 can open or close the circuit of the gas supply unit supplying gas to the air bag 311 according to the tilt risk information, thereby realizing the control of the gas supply unit supplying gas to the air bag 311.

[0145] The pneumatic system controller 309 includes a plurality of valves. The air supply to the air bag 311 is realized by opening and closing the plurality of valves.

[0146] In one example, the seat adjustment system also includes a pressure reducing valve group, the gas supply unit includes a high-pressure gas source 301, the working pressure of the high-pressure gas source 301 is greater than the working pressure of the air bag 311, and the high-pressure gas source 301 is connected to the pneumatic system controller 309 through the pressure reducing valve group.

[0147] In this example, the high-pressure gas source 301 can provide sufficient high-pressure gas in a short time to meet the requirement of rapid inflation of the air bag 311. Since the air pressure of the high-pressure gas source 301 is much higher than the working pressure of the air bag 311, it is necessary to reduce the pressure of the gas supplied by the high-pressure gas source 301. The inlet of the pressure reducing valve group is suitable for connection with the high-pressure gas source 301, and the outlet of the pressure reducing valve group is suitable for connection with the air bag 311. The pressure reducing valve group can effectively reduce the pressure of the high-pressure gas supplied by the high-pressure gas source 301 to adapt to the working pressure of the pneumatic system controller 309 and the air bag 311 described below.

[0148] Optionally, the high-pressure air source 301 is an air source for an air suspension system of the vehicle. In this example, the air suspension system and the seat adjustment system share the high-pressure air source 301, thereby saving space inside the vehicle.

[0149] Alternatively, the high-pressure gas source 301 is an independently provided gas source so as to supply gas to the air bag 311 in a more timely manner.

[0150] In a specific example of this application, Figure 2 As shown, the pressure reducing valve group includes a plurality of pressure reducing valves connected in series.

[0151] Under normal circumstances, the pressure of the high-pressure gas of the high-pressure gas source 301 is much higher than the working pressure of the air bag 311. Using only one pressure reducing valve to reduce pressure requires high quality of the pressure reducing valve and easily causes damage to the pressure reducing valve. In this example, multiple pressure reducing valves are provided to reduce pressure on the high-pressure gas step by step, thereby effectively extending the service life of the pressure reducing valve group.

[0152] For example, the working pressure of the high-pressure gas source 301 is 2MPa. However, the maximum air pressure that the pneumatic system controller 309 can withstand is 0.2MPa. The rated working pressure of the air bag 311 is 0.15MPa. In order to meet the working pressure requirements of the pneumatic system controller 309 and the air bag 311, the pressure reducing valve group includes a first pressure reducing valve 304 and a second pressure reducing valve 305. The first pressure reducing valve 304 and the second pressure reducing valve 305 are connected in series on the pipeline between the high-pressure gas source 301 and the starting system controller. For example, the first pressure reducing valve 304 is used to reduce the pressure of the high-pressure gas output by the high-pressure gas source 301 from 2MPa to 0.2Mpa. The second pressure reducing valve 305 is used to reduce the pressure of the gas from 0.2MPa to the rated working pressure of the air bag 311, that is, 0.15MPa.

[0153] The high-pressure gas supplied by the high-pressure gas source 301 can be effectively decompressed by the multiple pressure reducing valves, and the multiple pressure reducing valves have a long service life.

[0154] In addition, even if some of the multiple pressure reducing valves fail, the other pressure reducing valves can still work, so the high-pressure gas can be prevented from damaging the components downstream of the pressure reducing valve group, thereby effectively reducing the failure rate of the seat adjustment system.

[0155] In an example, Figure 2 As shown, a first pressure sensing device is provided between the high pressure gas source 301 and the pneumatic system controller 309 .

[0156] The first pressure sensing device can effectively reflect the air pressure of the pipeline between the high-pressure air source 301 and the pneumatic system controller 309, thereby preventing the pneumatic system controller 309 from being damaged due to excessive air pressure in the pipeline.

[0157] In a specific embodiment of the present application, Figure 2 As shown, the first pressure sensing device includes a first pressure sensor 306. The first pressure sensor 306 is arranged between the first pressure reducing valve 304 and the second pressure reducing valve 305. The first pressure sensor 306 can effectively sense the air pressure at the outlet of the first pressure reducing valve 304, so as to determine whether the air pressure at the outlet meets the air intake requirement of the second pressure reducing valve 305.

[0158] In an example, Figures 2 to 3 As shown, the seat adjustment system includes a low-pressure gas source 302. The gas supply unit includes a high-pressure gas source 301. The working pressure of the high-pressure gas source 301 is higher than the working pressure of the low-pressure gas source 302. Both the low-pressure gas source 302 and the high-pressure gas source 301 are suitable for connecting to the pneumatic system controller 309. The low-pressure gas source 302 is used to adjust the seat according to the riding needs of the occupant.

[0159] In this example, the low-pressure air source 302 is used to adjust the seat according to the passenger's riding needs. For example, the passenger manually adjusts the seat position, the tilt angle of the backrest, and the angle of the seat wing to meet the passenger's riding needs. The passenger sends a control instruction to the low-pressure air source 302 and the pneumatic system controller 309 according to the manual adjustment requirements to achieve seat adjustment.

[0160] In this example, the air bag 311 has a high-pressure gas inlet 3111 and a low-pressure gas inlet 3112. The high-pressure gas inlet 3111 is used to supply gas from the high-pressure gas source 301 to the air bag 311. The low-pressure gas inlet 3112 is used to supply gas from the low-pressure gas source 302 to the air bag 311.

[0161] The high-pressure gas source 301 is used to realize the active adjustment function of the seat wing, that is, when the vehicle is driving and the roll exceeds a certain angle, the high-pressure gas source 301 actively supplies gas to adjust the angle of the seat wing to support the occupant. Under this condition, the volume of the air bag 311 needs to be quickly increased to the set value to meet the support requirements of the seat wing for the occupant. The high-pressure gas source 301 can provide a large amount of relatively high-pressure gas at one time.

[0162] The low-pressure air source 302 is used for passive seat adjustment, such as the above-mentioned seat adjustment according to the needs of the occupants. Under this condition, the adjustment speed does not need to be particularly fast, but needs to be gradually adjusted according to the riding experience of the occupants. For example, the passive adjustment can be set to multiple adjustment gears, each gear is suitable for occupants of corresponding body shapes. When adjusting the seat, it can be manually adjusted to different gears to meet the riding needs of the occupants.

[0163] In an example, Figure 2 As shown, at least one of the high-pressure gas source 301 and the low-pressure gas source 302 includes an air pump and an air storage tank, the air pump is connected to the air storage tank, and the air storage tank is suitable for connecting to the pneumatic system controller 309.

[0164] The gas storage tank can store gas for use in seat adjustment. By providing the gas storage tank, it is possible to avoid frequent opening and closing of the air pump.

[0165] Of course, in other examples, due to the small amount of gas used, the low-pressure gas source 302 may only include an air pump.

[0166] In an example, Figure 3 As shown, the low-pressure air source 302 is disposed on the seat.

[0167] For example, the low-pressure gas source 302 is arranged on the backrest of the seat or below the seat cushion. In this way, the pipeline design of the low-pressure gas source 302 can be effectively simplified.

[0168] In an example, Figure 2 As shown, the pneumatic system controller 309 includes a wing support solenoid valve 312. The high-pressure gas source 301 and the low-pressure gas source 302 are both connected to the wing support solenoid valve 312. The wing support solenoid valve 312 is connected to the air bag 311.

[0169] In this example, the wing support solenoid valve 312 is used to switch the operation of the high-pressure air source 301 and the low-pressure air source 302 to meet the requirements of active adjustment and passive adjustment of the seat wing.

[0170] In an example, Figure 2 As shown, the pneumatic system controller 309 includes a switch valve 310. The high-pressure gas source 301 is suitable for connecting to the wing support solenoid valve 312 through the switch valve 310. Under the conditions that the speed of the vehicle is greater than or equal to the speed threshold, and the tilt angle is greater than or equal to the adjustment threshold, the switch valve 310 is opened.

[0171] In this example, when the switch valve 310 is closed, the low-pressure air source 302 can supply air to the air bag 311 to adjust the seat. When the switch valve 310 is open, the high-pressure air source 301 can supply air to the air bag 311 to adjust the seat wing.

[0172] In an example, Figure 2 As shown, the wing support solenoid valve 312 includes an inflation valve 3121. The inflation valve 3121 is connected to the inflation end of the air bag 311. The switch valve 310 and the low-pressure air source 302 are both connected to the inflation valve 3121.

[0173] In this example, the seat adjustment system generally includes a plurality of air bags 311. The inflation valve 3121 distributes the gas supplied by the high-pressure gas source 301 and the low-pressure gas source 302 to the corresponding air bags 311 to adjust the seat wings.

[0174] In an example, Figure 2 As shown, the first pressure sensing device includes a third pressure sensor 307. The third pressure sensor 307 is arranged between the second pressure reducing valve 305 and the switch valve 310. The third pressure sensor 307 can effectively sense the outlet pressure of the second pressure reducing valve 305, so as to determine whether the pressure of the outlet meets the intake requirement of the switch valve 310.

[0175] In an example, Figure 2 As shown, a relief valve 313 is provided between the inflation valve 3121 and the inflation end of the air bag 311. The relief valve 313 is adapted to deflate when the air pressure between the inflation valve 3121 and the inflation end of the air bag 311 is greater than or equal to a set air pressure.

[0176] For example, the overflow valve 313 is installed on the pipeline between the inflation valve 3121 and the inflation end of the air bag 311. When the air pressure in the pipeline is abnormal, the overflow valve 313 opens to discharge the gas in the pipeline. In this way, the overflow valve 313 can protect the components in the seat adjustment system.

[0177] Those skilled in the art can set the exhaust pressure of the relief valve 313 according to actual needs.

[0178] In an example, Figure 2 As shown, a second pressure sensing device is provided between the inflation valve 3121 and the air bag 311 .

[0179] The second pressure sensing device includes a second pressure sensor 308. The second pressure sensor 308 is used to sense the air pressure of the pipeline between the inflation valve 3121 and the inflation end of the air bag 311. The air pressure can reflect the air pressure in the air bag 311. By providing the second pressure sensor 308, it is possible to effectively determine whether the air pressure in the air bag 311 meets the requirements of the seat wing adjustment, thereby preventing the air pressure in the air bag 311 from being too high or too low.

[0180] In addition, the second pressure sensor 308 can sense the air pressure in the second air bag 311, so as to determine the current state of the seat wing, so as to determine whether the current state of the seat wing needs to be adjusted.

[0181] In an example, Figure 2 As shown, the pneumatic system controller 309 includes an air release valve 3122. The air release valve 3122 is connected to the exhaust end of the air bag 311. The air release valve 3122 is used to exhaust the air bag 311.

[0182] In this example, the deflation valve 3122 is used to discharge the gas in the air bag 311 after the triggering condition is released, so as to restore the seat wing to the initial position.

[0183] In an example, Figure 2 As shown, the air inlet of the gas supply unit is suitable for taking in air from the vehicle cabin 303 .

[0184] The vehicle cabin 303 is, for example, a cockpit or a luggage compartment. Generally, the external environment of the vehicle is complex. For example, the quality of the air in the external environment is unstable, such as high dust content, high humidity, high content of toxic and hazardous substances, etc. If the inlet of the air intake pipe is set outside the vehicle, it may cause damage to the air supply unit.

[0185] However, the gas in the cabin 303 is usually filtered by the air filter of the vehicle, so the quality of the gas is stable and the content of harmful components is low. In this example, the air inlet of the gas supply unit is arranged in the cabin 303 to avoid damage to the gas supply unit due to poor air quality.

[0186] In a specific embodiment of the present application, the seat adjustment system adjusts the seat according to different risk parameters under different working conditions.

[0187] For example, the seat adjustment system works as follows to adjust according to the vehicle's tilt angle:

[0188] The vehicle is turned on and powered on. The first pressure sensing device located between the first pressure reducing valve 304 and the second pressure reducing valve 305 works. When the first pressure sensing device shows abnormal pressure, the air inlet of the high pressure gas source 301 is closed. When the first pressure sensing device shows normal pressure, the first pressure sensing device located between the second pressure reducing valve 305 and the switch valve 310 works. When the first pressure sensing device shows abnormal pressure, the air inlet of the high pressure gas source 301 is closed.

[0189] When the first pressure sensing device displays normal pressure, the adjusting device determines whether the vehicle's driving speed reaches a speed threshold. When the vehicle's driving speed does not reach the speed threshold, the active adjustment function of the seat wing is not turned on.

[0190] When the vehicle's running speed reaches a speed threshold, the adjustment device determines whether the vehicle's tilt angle reaches a first angle threshold. When the first angle threshold is not reached, the active adjustment function of the seat wing is not turned on.

[0191] Under the condition that the first angle threshold is reached, the regulating device determines whether the tilt angle of the vehicle reaches the second angle threshold. Under the condition that the second angle threshold is not reached, the control unit 200 determines whether the current air pressure of the air bag 311 reaches the target air pressure in the first regulating parameter corresponding to the first angle threshold. Under the condition that the target air pressure is not reached, the first regulating parameter of the seat wing is generated. The switch valve 310 is opened to inflate the air bag 311 on the same side as the roll direction. Under the condition that the target air pressure is reached, the switch valve 310 is not opened. The active regulating function of the seat wing is not turned on.

[0192] Under the condition that the second angle threshold is reached, the regulating device determines whether the current air pressure of the air bag 311 reaches the target air pressure in the second regulating parameter corresponding to the second angle threshold. Under the condition that the target air pressure is not reached, the second regulating parameter of the seat wing is generated. The switch valve 310 is opened to inflate the air bag 311 on the same side as the roll direction. Under the condition that the target air pressure is reached, the switch valve 310 is not opened. The active regulating function of the seat wing is not turned on.

[0193] For example, the seat adjustment system works as follows to adjust the seat wing according to the steering angle of the steering wheel:

[0194] The vehicle is turned on and powered on. The first pressure sensing device located between the first pressure reducing valve 304 and the second pressure reducing valve 305 works. When the first pressure sensing device shows abnormal pressure, the air inlet of the high pressure gas source 301 is closed. When the first pressure sensing device shows normal pressure, the first pressure sensing device located between the second pressure reducing valve 305 and the switch valve 310 works. When the first pressure sensing device shows abnormal pressure, the air inlet of the high pressure gas source 301 is closed.

[0195] When the pressure displayed by the first pressure sensing device is normal, the adjustment device determines whether the speed of the vehicle reaches the speed threshold. When the speed of the vehicle does not reach the speed threshold, the control unit 200 does not generate the adjustment parameters of the seat wing. The active adjustment function of the seat wing is not turned on.

[0196] When the speed of the vehicle reaches the speed threshold, the adjustment device determines whether the steering angle of the steering wheel reaches the first turning angle threshold. When the first turning angle threshold is not reached, the adjustment parameters of the seat wing are not generated. The active adjustment function of the seat wing is not turned on.

[0197] Under the condition that the first turning angle threshold is reached, the regulating device determines whether the tilt angle of the vehicle reaches the second turning angle threshold. Under the condition that the second turning angle threshold is not reached, it is determined whether the current air pressure of the air bag 311 reaches the target air pressure in the third regulating parameter corresponding to the first turning angle threshold. Under the condition that the target air pressure is not reached, the third regulating parameter of the seat wing is generated. The switch valve 310 is opened to inflate the air bag 311 on the opposite side of the roll direction. Under the condition that the target air pressure is reached, the switch valve 310 is not opened. The active regulating function of the seat wing is not turned on.

[0198] Under the condition that the second turning angle threshold is reached, the regulating device determines whether the current air pressure of the air bag 311 reaches the target air pressure in the fourth regulating parameter corresponding to the second turning angle threshold. Under the condition that the target air pressure is not reached, the fourth regulating parameter of the seat wing is generated. The switch valve 310 is opened to inflate the air bag 311 on the opposite side of the roll direction. Under the condition that the target air pressure is reached, the switch valve 310 is not opened. The active regulating function of the seat wing is not turned on.

[0199] In the embodiment of the present application, the seat adjustment system adjusts the seat according to different parameters under different working conditions. In this way, the use requirements of the vehicle under different working conditions can be met.

[0200] According to yet another embodiment of the present application, a vehicle is provided, which includes the seat adjustment system as described above.
