The real-time situation of road surface transform can be monitored through the vision camera:
firstly, if the front of the road surface has a bulge:
1. when the projection amplitude is small: when the vehicle directly runs over the road surface, the height of the front end of the vehicle is increased suddenly, so that large impact force is generated during landing, the front end air suspension mechanism 3 operates, the lower air damper 4 is deflated, the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is reduced, so that the overall height of the front end of the vehicle is reduced, the rear end air suspension mechanism 3 does not operate, so that when the front end of the vehicle runs over the road surface, the height of the front end is reduced, the height of the rear end is unchanged, the height of the front end of the vehicle is equal to the height of the rear end of the vehicle, the overall horizontal height of the vehicle is unchanged, so that small amplitude is generated, and the vehicle can smoothly pass through the road surface protrusion;
then when the front wheel of the vehicle passes through the road surface bulge, the lower air damper 4 is inflated to increase the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2, so that the overall height of the front end of the vehicle is raised, and the rear end air suspension mechanism 3 of the vehicle does not operate, so that the height of the front end of the vehicle is equal to the height of the rear end of the vehicle;
finally when the vehicle rear wheel is about to pass through the road surface and is protruding, through the operation of rear end air suspension mechanism 3, the gassing of air damper 4 down, reduce coupling mechanism 1 and last coupling mechanism 2's interval down, thereby reduce the overall height of vehicle rear end, and the front end air suspension mechanism 3 of vehicle does not operate, when making the vehicle rear end drive and cross the road surface and protruding, the unchangeable rear end height of front end height reduces, the vehicle front end height equals the vehicle rear end height, make the whole level height of vehicle unchangeable, thereby produce less amplitude, make the vehicle can be gently protruding through the road surface.
2. When the projection amplitude is large: the front-end air suspension mechanism 3 operates, the lower air damper 4 and the upper air damper 8 simultaneously deflate, when the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is reduced to the minimum and the height of the front end of the vehicle is still higher than the height of the rear end of the vehicle, the vehicle can bump, at the moment, the height adjusting mechanism 9 is started to operate, the distance between the lower connecting plate 5 and the upper connecting plate 7 is reduced, so that the front end of the vehicle is reduced to the lowest position, the rear-end air suspension mechanism 3 operates, when the front end of the vehicle does not run over a road surface bulge, the height of the front end is reduced, the height of the rear end is unchanged, the height of the front end of the vehicle and the height of the rear end of the vehicle keep the minimum height difference, the minimum amplitude is generated, and the vehicle can smoothly pass through the road surface bulge;
then, after the front wheel of the vehicle passes through the road surface bulge, the lower air damper 4 and the upper air damper 8 are inflated to increase the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2, the height adjusting mechanism 9 operates again to increase the distance between the lower connecting plate 5 and the upper connecting plate 7, so that the overall height of the front end of the vehicle is raised, and the rear end air suspension mechanism 3 of the vehicle does not operate, so that the height difference between the front end of the vehicle and the rear end of the vehicle is reduced to the maximum extent;
finally when the vehicle rear wheel is about to pass through the road surface protrusion, the operation is carried out through the rear end air suspension mechanism 3, the lower air damper 4 and the upper air damper 8 deflate simultaneously, the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is reduced to the shortest, the operation of the height adjusting mechanism 9 is started simultaneously, the distance between the lower connecting plate 5 and the upper connecting plate 7 is reduced, the vehicle rear end is reduced to the lowest position, the front end air suspension mechanism 3 does not operate, when the vehicle rear end drives to cross the road surface protrusion, the height of the vehicle front end and the height of the vehicle rear end keep the minimum height difference, the minimum amplitude is generated, and the vehicle can smoothly pass through the road surface protrusion.
Secondly, if there is a depression in front of the road surface

then, after the front wheel of the vehicle passes through a depression on the road surface, the lower air damper 4 is deflated, and the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is reduced, so that the overall height of the front end of the vehicle is reduced, and the rear end air suspension mechanism 3 of the vehicle does not operate, so that the height of the front end of the vehicle is equal to the height of the rear end of the vehicle;
finally when the vehicle rear wheel is about to pass through the road surface pothole, through the operation of rear end air suspension mechanism 3, lower air damper 4 aerifys, increase the interval of coupling mechanism 1 and last coupling mechanism 2 down, thereby raise the whole height of vehicle rear end, and the front end air suspension mechanism 3 of vehicle does not operate, make the vehicle rear end when driving over the road surface pothole, the front end height does not change the rear end height and raises, the vehicle front end height equals the vehicle rear end height, make the whole level height of vehicle unchangeable, thereby produce less amplitude, make the vehicle can be gently through the road surface pothole.
2. When the depression width is large: through the operation of the front-end air suspension mechanism 3, the lower air damper 4 and the upper air damper 8 are inflated simultaneously, when the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is increased to the longest distance, and the height of the front end of the vehicle is still lower than the height of the rear end of the vehicle, the vehicle can bump, at the moment, the height adjusting mechanism 9 is started to operate, the distance between the lower connecting plate 5 and the upper connecting plate 7 is increased, so that the front end of the vehicle is lifted to the highest position, the rear-end air suspension mechanism 3 operates, when the front end of the vehicle does not run over a road pit, the height of the front end lifted by the height of the rear end is unchanged, the height difference between the front end of the vehicle and the height of the rear end of the vehicle is kept to the smallest, the smallest amplitude is generated, and the vehicle can smoothly pass through the road pit;
then, after the front wheel of the vehicle passes through a depression on the road surface, the lower air damper 4 and the upper air damper 8 are deflated, the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is reduced, the height adjusting mechanism 9 operates again, and the distance between the lower connecting plate 5 and the upper connecting plate 7 is reduced, so that the overall height of the front end of the vehicle is reduced, the rear end air suspension mechanism 3 of the vehicle does not operate, and the height difference between the front end of the vehicle and the rear end of the vehicle is reduced to the greatest extent;
finally, when the rear wheel of the vehicle is about to pass through a road depression, the rear-end air suspension mechanism 3 operates, the lower air damper 4 and the upper air damper 8 are inflated simultaneously, the distance between the lower connecting mechanism 1 and the upper connecting mechanism 2 is increased to the maximum, the height adjusting mechanism 9 is opened to operate simultaneously, the distance between the lower connecting plate 5 and the upper connecting plate 7 is increased, the rear end of the vehicle is raised to the maximum, the front-end air suspension mechanism 3 does not operate, when the rear end of the vehicle runs over the road depression, the height of the front end of the vehicle and the height of the rear end of the vehicle keep the minimum height difference, the minimum amplitude is generated, and the vehicle can smoothly pass through the road depression.
Thirdly, if there are bumps in the front of the road surface and depressions in the back
