the current height of the vehicle is read by the height sensor, the target height of the vehicle is provided for the controller by the vehicle controller through a CAN line, and the controller judges that the vehicle needs to be lifted, lowered or maintained by comparing the current height with the target height.
General conditions requiring a reduction in vehicle height: the vehicle load becomes smaller, resulting in an increase in the vehicle height; receiving a command of reducing the vehicle height required by a driver transmitted by a CAN line or automatically reducing a threshold value when the vehicle speed is higher than the vehicle height along with the vehicle speed;
the working method of the control system when the vehicle height is reduced comprises the following steps: the controller opens the valve port of the air spring to be deflated in the air distribution main valve 5 and simultaneously opens theexhaust valve 8, and high-pressure air is exhausted to the atmosphere from the corresponding air spring through the air distribution main valve 5 and theair filter 73. After the pressure of the air spring is reduced, the height is reduced, and the height of the vehicle is reduced.

the working method of the control system when the vehicle height is reduced comprises the following steps: if the air quantity in theair storage tank 62 is sufficient, the controller opens the air storage control valve 61 and the control valve of the corresponding air spring, high-pressure air flows to the corresponding air spring from theair storage tank 62, and the air spring extends after being inflated, so that the vehicle is lifted. If the air pressure of theair storage tank 62 is detected to be insufficient or the vehicle is lifted too slowly in the using process, the controller is communicated with the relay, theair compressor 7 is started, the air storage control valve 61 is closed, the control valve of the air spring needing to be lifted is opened, theair compressor 7 inflates the corresponding air spring, and the vehicle is lifted.
When the vehicle height lifting function is not activated, the controller closes all valve ports of the gas distribution main valve 5.
When the air suspension system inhales air, the air compressor compresses and inhales air filtered by theair filter 73, and after compression and pressure rise, high-pressure air is supplied to the corresponding air spring orair storage tank 62 through the air distribution main valve 5. When exhausting, the high-pressure gas of the corresponding air spring is discharged from the air spring to the atmosphere through the gas distribution main valve 5 and theair filter 73. The same pipeline is adopted for air intake and exhaust, which is helpful for realizing self-cleaning of theair filter 73, and impurities remained in theair filter 73 during air suction can be discharged during air exhaust.
The controller can pass throughpressure sensor 9 at the driving in-process, detectsgas holder 62 pressure, ifgas holder 62 pressure is less than the threshold value, the controller can communicate the relay, and then startsair compressor 7, opens storage control valve 61 simultaneously, for thegas holder 62 tonifying qi, the gas tonifying in-process passes throughpressure sensor 9monitoring gas holder 62 pressure, when pressure reaches the target, closesair compressor 7 and storage control valve 61, stops forgas holder 62 air feed. The high pressure gas stored in thereservoir 62 can be used to inflate the air springs, reducing the time required to raise the vehicle.
