The invention belongs to the technical field of automobile control, and particularly relates to an automobile chassis hydraulic lifting system and a hydraulic lifting method. Comprising a hydraulic mechanism and a lifting mechanism. The hydraulic mechanism comprises an oil storage tank and a bidirectional hydraulic pump, the oil storage tank is connected with an oil pipe, and the bidirectional hydraulic pump is arranged on the oil pipe; the plurality of lifting mechanisms are respectively mounted on the front suspension and the rear suspension; the lifting mechanism comprises a hydraulic lifting rod and a spring tray, the upper end of the spring tray is in contact with the sliding column spring, and the upper end of the hydraulic lifting rod is connected with the spring tray; the oil pipe is communicated with the hydraulic lifting rod; the two sides of the front suspension and the two sides of the rear suspension are each provided with a sensor assembly. A gyroscope is arranged near the mass center of the whole vehicle; the controller is in signal connection with the gyroscope; the height of the automobile chassis can be adjusted according to road conditions, different adjustments can be carried out according to different road conditions, the chassis is prevented from being collided under complex road conditions, normal passing is avoided, wind resistance can be reduced when the automobile runs on a flat road surface at a high speed, and the experience feeling of the automobile in the using process is guaranteed.

    本发明属于汽车控制技术领域,特别涉及一种汽车底盘液压举升系统及液压举升方法;包括液压机构和举升机构;液压机构包括储油罐和双向液压泵,储油罐与油管连接,油管上设置有双向液压泵;多个举升机构分别安装在前悬架和后悬架上;举升机构包括液压举升杆和弹簧托盘,弹簧托盘的上端与滑柱弹簧接触,液压举升杆的上端与弹簧托盘连接;油管与液压举升杆连通;前悬架和后悬架两侧上均安装有传感器总成;在整车质心附近布置有陀螺仪;控制器与陀螺仪信号连接;实现根据路况的情况,调整汽车底盘的高低,实现根据不同的路况进行不同的调整,在复杂路况时避免底盘磕碰正常通行,在平整路面高速行驶时能够降低风阻,保证汽车在使用过程中的体验感。
