[0050] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0051] Air suspension: A high-quality SUV must have the comfort of a sedan and the passability of an off-road vehicle. The air suspension system is the best choice to achieve this goal. According to different road conditions and the signal of the distance sensor, the on-board computer will determine the change in vehicle height, and then control the air compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the ground clearance of the chassis to increase high-speed vehicle stability or passability in complex road conditions.

[0052] Air spring: A spring that is filled with compressed air in a retractable sealed container and uses the elasticity of air. Commonly known as airbag, airbag cylinder, leather bag cylinder, etc.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0054] In a first aspect, an embodiment of the present application provides an air spring adjustment method.

[0055] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the air spring adjustment method of this application. Figure 1 As shown, the air spring adjustment method includes:

[0056] Step S10, during the single-axis height adjustment process, detecting whether the single-axis height reaches the target height;

[0057] In this embodiment, the single axle refers to the front axle or rear axle of the vehicle, and the height adjustment process is a height increase process or a height decrease process. The single axle height adjustment process referred to here can be a single axle height increase process, a single axle height decrease process, a rear axle height increase process, or a rear axle height decrease process.

[0058] The single-axis height can be measured by a height sensor installed at a specific position on the single axis (for example, the middle of the single axis).

[0059] The target height is set by the user or specified by the system based on relevant parameters.

[0060] During the single-axis height adjustment process (i.e., the adjustment process has not ended), the single-axis height is compared with the target height in real time. When it is detected that the difference between the single-axis height and the target height is less than or equal to a certain value, it is determined that the single-axis height has reached the target height; otherwise, it is determined that the single-axis height has not reached the target height.

[0061] Step S20, if the target height is reached, stop adjusting;

[0062] In this embodiment, if the single-axis height reaches the target height, the adjustment is stopped, that is, the single-axis height adjustment process ends.

[0063] Step S30, if the target height is not reached, calculating in real time the absolute value of the height difference between the first height value collected by the first height sensor and the second height value collected by the second height sensor, wherein the first height sensor and the second height sensor are respectively located on both sides of the single axis;

[0064] In this embodiment, if the single-axis height does not reach the target height, the absolute value of the height difference between the first height value collected by the first height sensor and the second height value collected by the second height sensor is calculated in real time.

[0065] Among them, the first height sensor and the second height sensor are respectively located on both sides of the single axis. It is easy to understand that under such an arrangement, the absolute value of the height difference can characterize the degree of height deviation around the single axis, that is, the larger the absolute value of the height difference, the higher the degree of height deviation around the single axis.

[0066] Step S40, if the absolute value of the height difference is less than or equal to the threshold, the air distribution valves on both sides of the single shaft are controlled to open, and the process returns to the step of detecting whether the height of the single shaft reaches the target height;

[0067] In this embodiment, the threshold value may be manually set based on human experience, or automatically set based on the current adjustment scenario.

[0068] When the absolute value of the height difference is less than or equal to the threshold, it means that the height deviation of the single axis on both sides is very low and at a normal level. Then the air distribution valves on both sides of the single axis continue to be controlled to open, and return to the step of detecting whether the height of the single axis reaches the target height.

[0069] Step S50, if the absolute value of the height difference is greater than the threshold, the target air distribution valve is determined from the air distribution valves on both sides of the single axis according to the selection rule corresponding to the single-axis height adjustment type, the target air distribution valve is controlled to be closed and the non-target air distribution valve is controlled to be opened, and the step of detecting whether the single-axis height reaches the target height is returned.

[0070] In this embodiment, if the absolute value of the height difference is greater than the threshold, it means that the height deviation of the left and right axes is high, and the adjustment process needs to be intervened. Specifically, the target air distribution valve is determined from the air distribution valves on both sides of the axis according to the selection rule corresponding to the single-axis height adjustment type corresponding to the single-axis height adjustment process, and the target air distribution valve is controlled to be closed and the non-target air distribution valve is controlled to be opened.

[0071] Further, in one embodiment, when the single-axis height adjustment type is the ascending type, the corresponding selection rule is:

[0072] The air distribution valve on the side where the height sensor corresponding to the maximum value of the first height value and the second height value is located is taken as the target air distribution valve.

[0073] In this embodiment, when the height adjustment type of the single axis is the rising type, the air springs on both sides of the single axis need to be inflated. If the absolute value of the height difference is greater than the threshold, the air distribution valve on the side of the height sensor corresponding to the maximum value of the first height value and the second height value is used as the target air distribution valve. For example, the first height value is located on the left side of the single axis, the second height value is located on the right side of the single axis, and the first height value is greater than the second height value. The air distribution valve on the left side of the single axis is used as the target air distribution valve, and the air distribution valve on the left side is closed, and the air distribution valve on the right side is kept closed, that is, the air spring on the left side is stopped from being inflated, and the air spring on the right side is kept inflated, thereby reducing the height deviation degree of the single axis left and right.

[0074] Further, in one embodiment, when the single-axis height adjustment type is a descending type, the corresponding selection rule is:

[0075] The air distribution valve on the side where the height sensor corresponding to the minimum value of the first height value and the second height value is located is taken as the target air distribution valve.

[0076] In this embodiment, when the height adjustment type of the single shaft is the descending type, the air springs on both sides of the single shaft need to be deflated. If the absolute value of the height difference is greater than the threshold, the air distribution valve on the side of the height sensor corresponding to the minimum value of the first height value and the second height value is used as the target air distribution valve. For example, if the first height value is located on the left side of the single shaft, the second height value is located on the right side of the single shaft, and the first height value is less than the second height value, the air distribution valve on the left side of the single shaft is used as the target air distribution valve, and the air distribution valve on the left side is closed, and the air distribution valve on the right side is kept closed, that is, the air spring on the left side is stopped from being deflated, and the air spring on the right side is kept deflated, thereby reducing the height deviation degree of the single shaft left and right.

[0077] In the embodiment of the present application, during the single-axis height adjustment process, it is detected whether the single-axis height reaches the target height; if it reaches the target height, the adjustment is stopped; if it does not reach the target height, the absolute value of the height difference between the first height value collected by the first height sensor and the second height value collected by the second height sensor is calculated in real time, wherein the first height sensor and the second height sensor are respectively located on both sides of the single axis; if the absolute value of the height difference is less than or equal to the threshold, the air distribution valves on both sides of the single axis are controlled to open, and the step of detecting whether the single axis height reaches the target height is returned; if the absolute value of the height difference is greater than the threshold, the target air distribution valve is determined from the air distribution valves on both sides of the single axis according to the selection rule corresponding to the single axis height adjustment type, the target air distribution valve is controlled to close and the non-target air distribution valve is controlled to open, and the step of detecting whether the single axis height reaches the target height is returned. Through the embodiment of the present application, the heights on both sides of the single axis are compared in real time, so that the opening and closing of the air distribution valves on both sides of the single axis are controlled according to the comparison result, thereby ensuring the consistency of the heights on both sides of the single axis during the adjustment process.

[0078] Furthermore, in one embodiment, before step S10, the method further includes:

[0079] Get the target height;

[0080] If the single-axis initial height is lower than the target height, the single-axis height adjustment type is determined to be an ascending type;

[0081] If the single-axis initial height is higher than the target height, the single-axis height adjustment type is determined to be a descending type.

[0082] In this embodiment, the target height is set manually by the user or automatically by the device according to the scene the vehicle is in. The single-axis initial height refers to the single-axis height when the target height is obtained. The single-axis initial height is compared with the target height. If the single-axis initial height is lower than the target height, the air springs on both sides of the single axis need to be inflated, that is, the single-axis height adjustment type is determined to be the rising type; if the single-axis initial height is higher than the target height, the air springs on both sides of the single axis need to be deflated, that is, the single-axis height adjustment type is determined to be the descending type.

[0083] Furthermore, in one embodiment, before step S10, the method further includes:

[0084] Determine a first value according to an absolute value of a difference between an initial height of a single axis and a target height;

[0085] Determining a second value according to the single-axis height adjustment speed;

[0086] determining a third value according to an inflation method;

[0087] The first value, the second value and the third value are weighted and summed according to a preset weighting coefficient, and the weighted sum result is used as a threshold.

[0088] In this embodiment, the absolute value of the difference between the initial height of the single axis and the target height is in direct proportion to the first numerical value, that is, the greater the absolute value of the difference between the initial height of the single axis and the target height, the greater the first numerical value determined, and the smaller the absolute value of the difference between the initial height of the single axis and the target height, the smaller the first numerical value determined. By pre-establishing a first mapping relationship between the absolute value of the difference between the initial height of the single axis and the target height and the numerical value, the first numerical value corresponding to the absolute value of the difference between the initial height of the single axis and the target height is determined based on the first mapping relationship.

[0089] The single-axis height adjustment speed is directly proportional to the second value, that is, the faster the single-axis height adjustment speed is, the larger the second value is, and the slower the single-axis height adjustment speed is, the smaller the first value is. By pre-establishing a second mapping relationship between the single-axis height adjustment speed and the value, the second value corresponding to the single-axis height adjustment speed is determined based on the second mapping relationship.

[0090] Generally speaking, there are three ways to inflate an air spring: inflate with an air pump alone, inflate with an air pump and an air tank at the same time, and inflate with an air tank alone. A value is set for each of the three ways of inflating, where the value corresponding to inflating with an air pump alone is the largest, the value corresponding to inflating with an air pump and an air tank at the same time is the second largest, and the value corresponding to inflating with an air tank alone is the smallest. Based on this, the third value can be determined according to the inflation method.

[0091] After determining the first value, the second value and the third value, weighted sum is performed on the first value, the second value and the third value according to a preset weighting coefficient, and the weighted sum result is used as the threshold value. The preset weighting coefficient is set according to actual needs.

[0092] In a second aspect, an embodiment of the present application also provides an air spring adjustment device.

[0094] The detection module 10 is used to detect whether the single-axis height reaches the target height during the single-axis height adjustment process;

[0095] A stop module 20 is used to stop adjusting if the target height is reached;

[0096] A calculation module 30, for calculating in real time if the target height is not reached, an absolute value of a height difference between a first height value collected by a first height sensor and a second height value collected by a second height sensor, wherein the first height sensor and the second height sensor are respectively located on two sides of a single axis;

[0097] The control module 40 is used for controlling the air distribution valves on both sides of the single shaft to open if the absolute value of the height difference is less than or equal to the threshold value, and returning to the step of detecting whether the height of the single shaft reaches the target height;

[0098] The control module 40 is also used to determine the target air distribution valve from the air distribution valves on both sides of the single axis according to the selection rule corresponding to the single-axis height adjustment type if the absolute value of the height difference is greater than a threshold value, control the target air distribution valve to close and control the non-target air distribution valve to open, and return to the step of detecting whether the single-axis height reaches the target height.

[0099] Further, in one embodiment, when the single-axis height adjustment type is the ascending type, the corresponding selection rule is:

[0100] The air distribution valve on the side of the height sensor corresponding to the maximum value of the first height value and the second height value is taken as the target air distribution valve;

[0101] When the single-axis height adjustment type is the descending type, the corresponding selection rules are:

[0102] The air distribution valve on the side where the height sensor corresponding to the minimum value of the first height value and the second height value is located is taken as the target air distribution valve.

[0103] Furthermore, in one embodiment, the air spring adjustment device further includes a setting module, which is used to:

[0104] Determine a first value according to an absolute value of a difference between an initial height of a single axis and a target height;

[0105] Determining a second value according to the single-axis height adjustment speed;

[0106] determining a third value according to an inflation method;

[0107] The first value, the second value and the third value are weighted and summed according to a preset weighting coefficient, and the weighted sum result is used as a threshold.

[0108] Furthermore, in one embodiment, the air spring adjustment device further includes a determination module, which is used to:

[0109] Get the target height;

[0110] If the single-axis initial height is lower than the target height, the single-axis height adjustment type is determined to be an ascending type;
