Embodiment 1

[0046] An embodiment of the present invention provides an automatically adjustable hydro-pneumatic suspension, which includes a hydro-pneumatic suspension body, a road condition information collection unit and a control unit;

[0047] The road condition information collection unit sends the collected road condition information to the control unit;

[0048] The control unit judges the roughness information and / or obstacle information of the road surface based on the road condition information, sends damping adjustment information corresponding to the roughness information to the damping adjustment unit in the oil-pneumatic suspension body, and adjusts the The opening of the damping adjustment unit can obtain the optimal damping corresponding to the current road conditions, which can quickly and effectively reduce the vibration of the vehicle body; and / or send the height adjustment information corresponding to the obstacle information to the oil-air suspension The height adjustm...

Embodiment 2

[0082] An embodiment of the present invention provides an adjustment method that can automatically adjust the oil-pneumatic suspension, including:

[0083] Obtain traffic information;

[0084] Determine the roughness information and / or obstacle height information of the road surface based on the road condition information, and send the damping adjustment information corresponding to the roughness information to the damping adjustment unit in the oil-pneumatic suspension body for adjusting the damping Adjust the opening of the unit to obtain the best damping corresponding to the current road conditions; and / or send the height adjustment information corresponding to the obstacle height information to the height adjustment unit in the oil-pneumatic suspension body for adjusting the Height adjusts the height of the unit to obtain the best height corresponding to the current obstacle.

[0085] In a specific implementation manner of the embodiment of the present invention, the calc...

Abstract

The invention discloses a control system and method capable of automatically adjusting a hydro-pneumatic suspension. The system comprises a hydro-pneumatic suspension body, a road condition information acquisition unit and a control unit, the road condition information acquisition unit sends acquired road condition information to the control unit; the control unit judges the unevenness informationand/or obstacle height information of the road surface based on the road condition information, damping adjustment information corresponding to the unevenness information is sent to a damping adjustment unit in the hydro-pneumatic suspension body, the opening degree of the damping adjustment unit is adjusted, and the optimal damping corresponding to the current road condition is obtained; and/orheight adjusting information corresponding to the obstacle height information is sent to a height adjusting unit in the hydro-pneumatic suspension body, the height of the hydro-pneumatic suspension body is adjusted, and the optimal height corresponding to the current obstacle is obtained. According to the invention, the road condition can be quickly and effectively recognized, then the height adjustment and/or damping adjustment are/is carried out on the hydro-pneumatic suspension body, and the hydro-pneumatic suspension is more intelligent.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a control system and method capable of automatically adjusting an oil-air suspension. Background technique [0002] Off-road vehicles play an important role in complex and harsh working conditions with excellent off-road performance. Nowadays, some high-performance off-road vehicles use oil-pneumatic suspension devices. This is because oil-pneumatic suspensions can not only effectively isolate vibrations In addition, it can also provide good ride comfort, handling stability and off-road passability. According to the mechanical characteristics of the oil-pneumatic suspension, matching and designing different suspension damping can improve the ride comfort of the off-road vehicle; changing the expansion and contraction of the suspension cylinder can realize the adjustment of the body posture and further improve the passing performance of the off-road vehicle...
