The first air pressure detecting unit 10 is used for detecting the air pressure of a left air bag 61 of the air suspension of the vehicle, the second air pressure detecting unit 20 is used for detecting the air pressure of a right air bag 64 of the air suspension of the vehicle, the first height detecting unit 30 is used for detecting the left suspension height of the air suspension of the vehicle, and the second height detecting unit 40 is used for detecting the right suspension height of the air suspension of the vehicle.
It should be noted that the vehicle air suspension includes a left side air bag 61 and a right side air bag 64, the first air pressure detecting unit 10 can detect the air pressure of the left side air bag 61, the second air pressure detecting unit 20 can detect the air pressure of the right side air bag 64, and the vehicle air suspension includes a left side suspension and a right side suspension, the first height detecting unit 30 can detect the height of the left side suspension, and the second height detecting unit 40 can detect the height of the right side suspension.
The control unit is respectively connected with the first air pressure detection unit 10, the second air pressure detection unit 20, the first height detection unit 30 and the second height detection unit 40, and when the control unit determines that the vehicle air suspension is in the first load bearing state according to the air pressure of the left air bag 61 and the air pressure of the right air bag 64, the control unit carries out inflation and deflation adjustment on the left air bag 61 and the right air bag 64 of the vehicle air suspension according to the air pressure of the left air bag 61, the air pressure of the right air bag 64, the height of the left suspension and the height of the right suspension.
It should be explained that the control unit is connected to the first air pressure detecting unit 10 and the second air pressure detecting unit 20 in a communication manner, the first air pressure detecting unit 10 can transmit the air pressure value of the left air bag 61 to the control unit, the second air pressure detecting unit 20 can transmit the air pressure value of the right air bag 64 to the control unit, and the control unit can determine whether the air suspension of the vehicle is in the first load bearing state according to the air pressure value of the left air bag 61 and the air pressure value of the right air bag 64. The control unit is connected to the first height detection unit 30 and the second height detection unit 40, the first height detection unit 30 can transmit the left suspension height to the control unit, and the second height detection unit 40 can transmit the right suspension height to the control unit.
When the control unit determines that the vehicle air suspension is in the first load bearing state based on the air pressure value of the left side air bag 61 and the air pressure value of the right side air bag 64, the control unit can perform inflation and deflation adjustment of the left side air bag 61 and the right side air bag 64 of the vehicle air suspension based on the air pressure value of the left side air bag 61, the air pressure value of the right side air bag 64, the left side suspension height and the right side suspension height.
Alternatively, the control unit may determine that the vehicle air suspension is in the first load bearing state when both the air pressure value of the left side air bag 61 and the air pressure value of the right side air bag 64 are less than or equal to a predetermined value. For example, when the air pressure value of the left side air bag 61 and the air pressure value of the right side air bag 64 are both less than or equal to 2bar (pressure unit), the control unit may determine that the vehicle air suspension is in the first load bearing state, it is understood that 2bar is merely an exemplary description and does not represent that the predetermined value is necessarily 2bar, and the predetermined value may be set according to actual needs, for example, 2.1 bar. Also, the predetermined value may be set in the control unit in advance.
When the control unit determines that the vehicle air suspension is in the first load bearing state, the control unit may perform inflation and deflation adjustment of the left side air bag 61 and the right side air bag 64 of the vehicle air suspension according to the air pressure value of the left side air bag 61, the air pressure value of the right side air bag 64, the left side suspension height, and the right side suspension height.
For example, when the control unit determines that the air pressure value of the left air bag 61 is high and the air pressure value of the right air bag 64 is low, the control unit may perform deflation adjustment on the left air bag 61 and inflation adjustment on the right air bag 64 until the air pressure value of the left air bag 61 and the air pressure value of the right air bag 64 are equal, and when performing inflation adjustment on the left air bag 61 and the right air bag 64, the first height detecting unit 30 and the second height detecting unit 40 may continuously feed back the left suspension height and the right suspension height to the control unit, and the control unit may ensure that the left suspension height and the right suspension height are the same when performing inflation adjustment on the left air bag 61 and the right air bag 64.
In the related art, when the air suspension of a vehicle is in a first load bearing state, the situation that the air pressures of the left air bag and the right air bag of the air suspension are inconsistent can occur, for example, the situation that the air pressure of the air bag on one side is higher and the air pressure of the air bag on one side is lower can occur, the situation can lead to the height inconsistency of the left suspension height and the right suspension height, furthermore, the rubber material of the air bag with lower air pressure can be wrinkled for a long time, the cracking phenomenon of the air bag can be caused by the long-time wrinkling of the rubber material of the air bag, the service life of the air bag can be influenced, and the use reliability of the air suspension can be influenced.
In the present application, when the air suspension of the vehicle is in the first load-bearing state, the control unit may perform inflation and deflation adjustment of the left air bag 61 and the right air bag 64 of the air suspension of the vehicle according to the air pressure of the left air bag 61, the air pressure of the right air bag 64, the height of the left suspension, and the height of the right suspension, and may ensure that the heights of the left suspension and the right suspension are the same. Therefore, the phenomenon that the air bag cracks can be avoided due to the fact that the air pressure of the left air bag 61 is inconsistent with that of the right air bag 64, the service life of the air bag can be prolonged, and the use reliability of the air suspension can be guaranteed.
From this, through vehicle air suspension control system 100 of this application, when vehicle air suspension is in first load bearing state, can fill the gassing to air suspension's left side gasbag 61 and right side gasbag 64 and adjust to can avoid the long-time fold of sizing material of gasbag, can avoid the gasbag phenomenon of cracking to appear, can improve the life of gasbag, can guarantee air suspension's use reliability.
In addition, through the vehicle air suspension control system 100 of this application, when vehicle air suspension is in first load bearing state, through filling the gassing and adjusting to the left side gasbag 61 and the right side gasbag 64 of air suspension, can also avoid appearing that one side air spring atmospheric pressure is higher, the lower condition of one side air spring atmospheric pressure to can avoid air spring to damage, can improve air spring's life, can further guarantee air suspension's use reliability.
In some embodiments of the present invention, the control unit may be further configured to perform inflation and deflation adjustment of the left side air bag 61 and the right side air bag 64 of the vehicle air suspension according to the left side suspension height and the right side suspension height when it is determined that the vehicle air suspension is in the second load bearing state according to the left side air bag 61 air pressure and the right side air bag 64 air pressure.
Alternatively, when the air pressure value of the left side air bag 61 or the air pressure value of the right side air bag 64 is greater than a predetermined value, then the control unit may determine that the vehicle air suspension is not in the first load bearing state (i.e., the vehicle air suspension is in the second load bearing state). For example, when the air pressure value of the left side air bag 61 or the air pressure value of the right side air bag 64 is greater than 2bar (pressure unit), the control unit may determine that the vehicle air suspension is in the second load bearing state, it is understood that 2bar is only an exemplary description and does not represent that the predetermined value is necessarily 2bar, and the predetermined value may be set according to actual needs, for example, 2.1 bar. Also, the predetermined value may be set in the control unit in advance.
Alternatively, when the vehicle air suspension is in the second load bearing state, the control unit may perform inflation and deflation adjustment of the left side air bag 61 and the right side air bag 64 of the vehicle air suspension according to the left side suspension height and the right side suspension height. I.e., the vehicle air suspension is in the second load bearing state, the control unit may not adjust the inflation and deflation of the left side air bag 61 and the right side air bag 64 based on the air pressure value of the left side air bag 61 and the air pressure value of the right side air bag 64. It can also be understood that the first and second air pressure detecting units 10, 20 do not intervene in the control strategy of the control unit when the vehicle air suspension is in the second load bearing state.
