[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] The seat stiffness adjustment method provided in this application embodiment can be applied to, for example... Figure 1The application environment is shown. The stiffness adjustment element 102 communicates with the detection device 104 via a network. The stiffness adjustment element 102 is used to adjust the seat stiffness and can be deployed on the seat to adjust the seat stiffness in real time. The stiffness adjustment element 102 includes a stiffness adjustment controller, which has a chip pre-stored the seat adjustment program. The seat stiffness is adjusted by calling the seat adjustment program. The detection device 104 is used to detect the road surface smoothness of the section of road ahead of the vehicle. The detection device includes, but is not limited to, radar, infrared detectors, etc. The stiffness adjustment element 102 can also communicate with a positioning device (not shown) via a network. The stiffness adjustment element 102 can also communicate with a server (not shown) via a network to obtain high-precision map data from the server. The data storage system can store the data that the server needs to process. The data storage system can be integrated on the server or placed in the cloud or other network servers. The stiffness adjustment element 102 acquires the current position of the target vehicle and obtains road condition data of the target road segment ahead of the current position from the map data; the road condition data includes the road surface slope; the stiffness adjustment element 102 acquires the detection information obtained by the detection equipment on the target road segment, and determines the road surface smoothness of the target road segment based on the detection information; the stiffness adjustment element 102 verifies the validity of the road condition data based on the road surface smoothness; if the validity verification passes and the current position is a turning point from a flat road segment to a non-flat road segment, the stiffness adjustment element 102 adjusts the stiffness of the seat in the target vehicle based on the road surface slope.

[0039] The server can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0040] In one exemplary embodiment, such as Figure 2 As shown, a method for determining seat stiffness is provided, which can be applied to... Figure 1 The following steps are used as an example to illustrate the stiffness adjustment element 102:

[0041] Step S202: Obtain the current location of the target vehicle and obtain the road condition data of the target road segment in front of the current location from the map data; the road condition data includes the road surface slope.

[0042] The target vehicles include those equipped with airbag seats, such as... Figure 3 The diagram shown is a structural schematic of a seat in one embodiment. The seat includes a backrest 1, a seat cushion 2, and a stiffness adjustment device 3. The stiffness adjustment device 3 is fixed to the cab floor and the seat cushion 2 by bolts. The stiffness adjustment device 3 has reserved air supply interface and wiring harness interface, and can be removed by simply removing the bolts. The stiffness adjustment device 3 includes an airbag 301 and a hydraulic cylinder 302. The stiffness adjustment device also includes stiffness adjustment elements.

[0043] When the seat moves downwards, the airbag 301 deflates to press against the seat cushion 2, providing cushioning and pressure relief. Simultaneously, the upper chamber of the hydraulic cylinder 302 is compressed, and the hydraulic oil in the upper chamber flows through the hydraulic lines to the power generation unit. This drives the hydraulic motor and generator to generate electricity, converting kinetic energy into electrical energy, which is then stored in the vehicle battery. When the seat moves upwards, the airbag 301 inflates, and the upper chamber of the hydraulic cylinder is stretched. The hydraulic oil in the upper chamber also flows through the hydraulic lines to the power generation unit. This again drives the hydraulic motor and generator to generate electricity, converting kinetic energy into electrical energy, which is also stored in the vehicle battery. In other words, when the seat moves upwards or downwards, kinetic energy can be converted into electrical energy to power the vehicle's electrical systems, thus contributing to energy conservation.

[0044] The target vehicle includes, but is not limited to, automobiles and commercial dump trucks. The current location is the physical location of the target vehicle at the current moment. The target road segment is the road segment located ahead of the current location and at a preset distance from the current location; it can be understood that the starting point of the target road segment is the current location.

[0045] The map data is high-precision map data, which includes road condition data for each physical location. Road condition data reflects the road conditions at each physical location, such as whether it is a flat road or an uphill road. Road slope refers to the angle between the road surface and the horizontal plane.

[0046] Optionally, the positioning device determines the current position of the target vehicle at the current moment. The positioning device sends the current position to the stiffness adjustment element. The stiffness adjustment element retrieves map data and obtains road condition data of the target road segment located ahead of the current position from the map data.

[0047] Among them, the positioning equipment is used to locate the position of the target vehicle. The positioning equipment includes, but is not limited to, GPS (Global Positioning System) locators and vehicle-mounted Beidou positioning terminals.

[0048] For example, the stiffness adjustment element sends a location acquisition request to the positioning device every preset time interval. Upon receiving the request, the positioning device sends the latitude and longitude information of the target vehicle at the current moment to the stiffness adjustment element. Alternatively, the positioning device can directly send its latitude and longitude information for each moment to the stiffness adjustment element. After every preset time interval, the stiffness adjustment element retrieves the current latitude and longitude information sent by the positioning device. The stiffness adjustment element then accesses map data and retrieves road condition data matching the latitude and longitude information from the map data. The preset time interval is determined by the target vehicle's speed and the distance to the target road segment; that is, it is determined based on the travel time it takes for the target vehicle to complete the target road segment. The travel time is no longer than the preset time interval.

[0049] Step S204: Obtain the detection information obtained by the detection equipment on the target road section, and determine the road surface smoothness of the target road section based on the detection information.

[0050] The detection equipment is used to detect the road surface of the target section in real time to determine its smoothness. Road surface smoothness reflects the degree of deviation of the physical surface from an ideal plane; the smaller the deviation, the smoother the road surface. Road surface smoothness is used to verify whether the road surface is smooth.

[0051] Optionally, after the target vehicle reaches its current location, the detection device detects the road surface of the target road segment ahead of the current location and obtains detection information. The stiffness adjustment element receives the detection information sent by the detection device at the current moment and determines the road surface smoothness of the target road segment based on the detection information.

[0052] For example, the detection device detects the road surface of a target road segment ahead of the current location, obtaining detection information of the target road segment. This detection information includes the road surface power spectral density. A stiffness adjustment element determines the road surface smoothness based on the road surface power spectral density. The road surface power spectral density refers to the distribution density of energy on the road surface at different frequencies. It can be understood as a function of the road surface height.

[0053] Step S206: Verify the validity of the road condition data based on the road surface smoothness.

[0054] The validity check is used to verify whether the road condition data has changed. For example, if the road surface changes, such as a large pothole appearing on a flat surface or a slope changing from flat to sloping, the road condition data is determined based on latitude and longitude information. While road surface changes do not affect latitude and longitude, they do affect road surface smoothness. Therefore, the road surface smoothness can be used to verify the validity of the road condition data at the current location. If the validity check passes, the road condition data is considered valid, and subsequent seat adjustments based on this data are valid.

[0055] In some embodiments, the traffic data includes road segment types. The validity of the traffic data is verified based on the road surface smoothness, including: estimating the road segment type of the target road segment based on the road surface smoothness; and determining that the validity verification passes if the estimated road segment type is the same as the road segment type in the traffic data.

[0056] Optionally, the stiffness adjustment element estimates the road segment type of the target road segment at the current moment based on the road surface smoothness, and compares the estimated road segment type with the road segment type in the road condition data. If the estimated road segment type is the same as the road segment type in the road condition data, the validity check is deemed successful.

[0057] If the estimated road segment type is inconsistent with the road segment type in the road condition data, the validity check is deemed to have failed, and the stiffness adjustment element will not adjust the stiffness of the seat in the target vehicle.

[0058] For example, if the road surface height at each physical location of the target road segment is consistent at the current time, then the road segment type of the target road segment at the current time is determined to be planar. If the road surface height at each physical location is inconsistent and the trend is gradually increasing or gradually decreasing, then the road segment type of the target road segment at the current time is determined to be non-planar, such as a slope.

[0059] In this embodiment, by comparing the road segment type estimated from the road surface smoothness with the road segment type in the road condition data, the validity of the road segment data type in the road condition data can be detected in real time, i.e., whether the road segment type of the target road segment has changed. Thus, provided the validity check passes, the seat stiffness can be adjusted effectively and promptly.

[0060] Step S208: If the validity check passes and the current position is a turning point from a flat road segment to a non-flat road segment, adjust the stiffness of the seat in the target vehicle according to the road slope.

[0061] Among them, road slope refers to the angle between the slope and the horizontal plane, and stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to force.

[0062] Optionally, if the validity check is passed, the stiffness adjustment element determines whether the road segment type has changed. If the road segment type has changed, and the current location is a non-planar road segment, then the current location is determined to be a transition point from a planar road segment to a non-planar road segment, and the stiffness adjustment element adjusts the seat stiffness according to the road surface slope.

[0063] If the current location is a transition point from a non-level road segment to a level road segment, the stiffness adjustment element will not adjust the seat stiffness.

[0064] In some embodiments, the method further includes: if the validity check passes and the current position is not a turning position, not adjusting the stiffness of the seat in the target vehicle.

[0065] For example, if the validity check is passed, the stiffness adjustment element determines whether the road segment type has changed. If the road segment type does not change, that is, both the target road segment at the previous moment and the target road segment at the current moment are planar road segments, the stiffness adjustment element does not adjust the stiffness of the seat in the target vehicle.

[0066] In this embodiment, if the validity check passes and the current position is not a turning point, it means that the current position is not a turning point from a flat road segment to a non-flat road segment, but is still a flat road segment. In this case, the stiffness of the seat in the target vehicle is adjusted to avoid ineffective adjustments and ensure the comfort of the user.

[0067] The aforementioned seat stiffness adjustment method obtains the current position of the target vehicle and quickly retrieves road condition data of the target road segment ahead of the current position from map data; the road condition data includes road surface slope. It acquires detection information obtained by detection equipment on the target road segment, and based on this information, the road surface smoothness of the target road segment can be determined in real time. The road condition data is then validated based on the road surface smoothness. This validation allows for rapid verification of the road condition of the target road segment, ensuring the validity of the road condition data. If the validity verification passes and the current position is at a transition point from a level road segment to a non-level road segment, the seat stiffness in the target vehicle is adjusted in advance based on the road surface slope, thus enabling timely stiffness adjustment.

[0068] In some embodiments, before obtaining the road condition data of the target road segment ahead of the current location from the map data, the method further includes: obtaining pre-stored stiffness adjustment data, the stiffness adjustment data including stiffness adjustment values ​​corresponding to each historical location; if it is found that the stiffness adjustment data does not store the stiffness adjustment value corresponding to the current location, then obtaining the road condition data of the target road segment ahead of the current location from the map data.

[0069] The stiffness adjustment is controlled by adjusting the opening of the regulating valve. Since the seat has an airbag, the regulating valve controls the airbag's air intake line. In this embodiment, the effective flow area of ​​the hydraulic cylinder's hydraulic line is adjusted by the regulating valve, thereby achieving damping adjustment of the hydraulic damping unit and ultimately adjusting the overall stiffness. Figure 4 The diagram shown is a structural schematic of a hydraulic damping unit in one embodiment. The hydraulic cylinder connects the engine M, generator E, rectifier circuit, and battery (or vehicle-mounted circuit). Figure 5 The diagram shown is a schematic of the regulating valve circuit in one embodiment. Gas enters through the inlet pipe and exits through the outlet pipe. The PID controller controls the gas flow rate by setting a setpoint. During gas intake, the gas flow rate is measured, and the flow rate is adjusted by controlling the opening of the solenoid valve, thereby changing the damping magnitude and achieving real-time vibration reduction.

[0070] The stiffness adjustment data is pre-stored in the stiffness adjustment element, including the stiffness adjustment values ​​from previous adjustments at historical locations. For example, at point A, when a vehicle first passes by, the seat is adjusted and the stiffness adjustment value is recorded. Thus, once the vehicle travels to point A again, the stiffness adjustment value at point A can be directly retrieved without recalculating it.

[0071] For example, the stiffness adjustment element obtains pre-stored stiffness adjustment data, which includes stiffness adjustment values ​​corresponding to each historical location. The stiffness adjustment element queries the stiffness adjustment data to see if the current location is recorded. If not, it is determined that no stiffness adjustment value corresponding to the current location is stored, and the stiffness adjustment element obtains the road condition data of the target road segment located ahead of the current location from the map data.

[0072] In some embodiments, the method further includes: if it is verified that the stiffness adjustment data stores a stiffness adjustment value corresponding to the current position, then obtaining the stiffness adjustment value of the current position from the stiffness adjustment data, and adjusting the seat stiffness of the target vehicle according to the stiffness adjustment value of the current position.

[0073] For example, the stiffness adjustment element queries the stiffness adjustment data to see if the current position is recorded. If it is, it is determined that the stiffness adjustment value corresponding to the current position is stored. The stiffness adjustment element directly obtains the stiffness adjustment value of the current position from the stiffness adjustment data and adjusts the seat stiffness of the target vehicle according to the stiffness adjustment value of the current position.

[0074] In this way, after determining the current position of the target vehicle, the system first checks whether the stiffness adjustment data stores the stiffness adjustment value for the current position. Once found, the stiffness adjustment value is directly retrieved from the stiffness adjustment data for stiffness adjustment, eliminating the need to re-determine the stiffness adjustment value and improving stiffness adjustment efficiency.

[0075] In this embodiment, by using pre-stored stiffness adjustment data, it is possible to quickly query whether there is a stored stiffness adjustment value for the current position. Based on the query result, it is determined whether the stiffness adjustment value for the current position needs to be determined, which simplifies the adjustment process and improves the efficiency of stiffness adjustment.

[0076] In some instances, the stiffness of the seat in a target vehicle is adjusted based on the road slope, including: obtaining the mapping relationship between the slope value and the flow area, where the flow area is the cross-sectional area of ​​the hydraulic lines of the hydraulic cylinder in the seat; determining the target flow area of ​​the hydraulic lines of the hydraulic cylinder in the seat based on the road slope and the mapping relationship; determining the target opening value of the regulating valve based on the target flow area; and adjusting the opening value of the regulating valve to the target opening value so that the stiffness of the seat is adjusted to the target stiffness.

[0077] Optionally, the stiffness adjustment element acquires the mapping relationship between the slope value and the flow area. Based on the road slope and the mapping relationship, the stiffness adjustment element determines the target flow area of ​​the hydraulic lines in the hydraulic cylinder of the seat. Based on the target flow area, the stiffness adjustment element determines the target opening value based on the mapping relationship between the opening value of the regulating valve and the flow area. The stiffness adjustment element adjusts the opening value of the regulating valve to the target opening value, thereby adjusting the stiffness of the seat to the target stiffness. The stiffness adjustment element uses this target opening value as the stiffness adjustment value corresponding to the current position and stores it in the stiffness adjustment data to update the stiffness adjustment data in real time. In other words, this embodiment of the application indirectly and accurately adjusts the stiffness by adjusting the opening value of the regulating valve.

[0078] In this embodiment, the target flow area of ​​the hydraulic pipeline can be accurately determined by mapping the slope value to the flow area. The target opening value of the regulating valve is then precisely determined based on the target flow area. Thus, by controlling the opening value of the regulating valve to the target opening value, the damping of the hydraulic vibration damping unit can be adjusted, thereby achieving adjustment of the overall stiffness.

[0079] In one specific embodiment, the seat stiffness adjustment method involves a positioning device, a stiffness adjustment element, and a detection device. The stiffness adjustment element includes a seat controller. Specifically, the positioning device locates the current position of the target vehicle. The seat controller in the stiffness adjustment element obtains the current position of the target vehicle sent by the positioning device, obtains pre-stored stiffness adjustment data, which includes stiffness adjustment values ​​corresponding to each historical position; and checks whether the stiffness adjustment data stores the stiffness adjustment value corresponding to the current position. If the stiffness adjustment data stores the stiffness adjustment value corresponding to the current position, the stiffness adjustment value for the current position is obtained from the stiffness adjustment data, and the seat stiffness of the target vehicle is adjusted according to the stiffness adjustment value for the current position. If the stiffness adjustment data does not store the stiffness adjustment value corresponding to the current position, road condition data of the target road segment ahead of the current position is obtained from map data; the road condition data includes road surface slope. The seat controller in the stiffness adjustment element obtains detection information obtained by the detection device from detecting the target road segment, and determines the road surface smoothness of the target road segment based on the detection information. Based on the road surface smoothness, the road segment type of the target road segment is estimated; if the estimated road segment type is the same as the road segment type in the road condition data, the validity verification is confirmed to be successful.

[0080] If the validity check passes and the current location is a transition point from a level road segment to a non-level road segment, the seat controller in the stiffness adjustment element obtains the mapping relationship between the slope value and the flow area, where the flow area is the cross-sectional area of ​​the hydraulic lines of the hydraulic cylinder in the seat. Based on the road slope and the mapping relationship, the target flow area of ​​the hydraulic lines of the hydraulic cylinder in the seat is determined. Based on the target flow area, the target opening value of the regulating valve is determined, and the opening value of the regulating valve is adjusted to the target opening value so that the seat stiffness is adjusted to the target stiffness. If the validity check passes and the current location is not a transition point, the stiffness of the seat in the target vehicle is not adjusted.

[0081] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0082] Based on the same inventive concept, this application also provides a seat stiffness adjustment device for implementing the seat stiffness adjustment method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations of one or more seat stiffness adjustment device embodiments provided below can be found in the limitations of the seat stiffness adjustment method described above, and will not be repeated here.

[0083] In one exemplary embodiment, such as Figure 6 As shown, a seat stiffness adjustment device 600 is provided, including: an acquisition module 602, a determination module 604, a verification module 606, and an adjustment module 608, wherein:

[0086] The verification module 606 is used to verify the validity of road condition data based on road surface smoothness.

[0087] The adjustment module 608 is used to adjust the stiffness of the seat in the target vehicle according to the road slope when the validity verification is passed and the current position is a turning point from a flat road segment to a non-flat road segment.

[0088] In some embodiments, before obtaining the road condition data of the target road segment ahead of the current location from the map data, the acquisition module 602 is further configured to obtain pre-stored stiffness adjustment data, which includes stiffness adjustment values ​​corresponding to each historical location; if it is found that the stiffness adjustment data does not store the stiffness adjustment value corresponding to the current location, the acquisition of the road condition data of the target road segment ahead of the current location from the map data is performed.

[0089] In some embodiments, the acquisition module 602 is further configured to, if it is verified that the stiffness adjustment value corresponding to the current position is stored in the stiffness adjustment data, obtain the stiffness adjustment value of the current position from the stiffness adjustment data, and adjust the seat stiffness of the target vehicle according to the stiffness adjustment value of the current position.

[0090] In some embodiments, the traffic data includes road segment types. The verification module 606 is used to estimate the road segment type of the target road segment based on the road surface smoothness. If the estimated road segment type is the same as the road segment type in the traffic data, the validity verification is determined to be successful.

[0091] In some embodiments, the adjustment module 608 is used to obtain the mapping relationship between the slope value and the flow area, where the flow area is the cross-sectional area of ​​the hydraulic pipeline of the hydraulic cylinder in the seat; determine the target flow area of ​​the hydraulic pipeline of the hydraulic cylinder in the seat according to the road slope and the mapping relationship; determine the target opening value of the adjustment valve according to the target flow area, and adjust the opening value of the adjustment valve to the target opening value so that the stiffness of the seat is adjusted to the target stiffness.

[0092] In some embodiments, the adjustment module 608 is further configured not to adjust the stiffness of the seat in the target vehicle if the validity check passes and the current position is not a turning position.

[0093] Each module in the aforementioned seat stiffness adjustment device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor within the stiffness adjustment element in hardware form, or stored in the memory of the stiffness adjustment element in software form, so that the processor can call and execute the corresponding operations of each module.

[0094] In one exemplary embodiment, a stiffness adjustment element is provided, which includes a seat controller. The seat controller may be a controller for a seat in a vehicle, and its internal structure diagram may be as shown below. Figure 7 As shown, the seat controller includes a processor, memory, input / output (I / O) interfaces, and a communication interface. The processor, memory, and I / O interfaces are connected via a system bus, and the communication interface is also connected to the system bus via the I / O interfaces. The processor provides computational and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the computer program. The internal memory provides an environment for the execution of the computer program in the non-volatile storage media. The I / O interfaces are used for exchanging information between the processor and external devices.
