The invention provides a trailer lifting axle automatic control system. The system comprises a height sensor which collects the height of a trailer airbag in a vertical direction, and obtains the height information of a trailer body; a trailer electronic braking system continuously collects trailer loads, obtains trailer load data, processes the load data and then sends a control instruction; an air suspension electromagnetic valve is connected with an air source, and is respectively connected with the height sensor and the trailer electronic braking system; the air suspension electromagneticvalve receives a control instruction sent by the trailer electronic braking system. Inflation or deflation of the trailer air bag is controlled; therefore, the trailer lifting axle ascends or descends; according to the real-time load data of the trailer air spring, the trailer lifting axle is automatically controlled to ascend and descend, so that the mode that the trailer lifting axle is manuallycontrolled to ascend or descend is replaced, automatic ascending and descending of the lifting axle are achieved, the lifting axle control process is more intelligent, oil consumption is reduced, andlosses of trailer tires in a non-full-load state are reduced.
本发明提供一种挂车提升桥自动控制系统,包括:高度传感器,高度传感器采集挂车气囊在垂直方向上的高度,获取车身高度信息;挂车电子制动系统连续采集挂车载荷,获取挂车载荷数据,并对载荷数据进行处理后发送控制指令;空气悬挂电磁阀与气源连接,并分别与高度传感器和挂车电子制动系统连接,空气悬挂电磁阀接收挂车电子制动系统发送的控制指令,控制挂车气囊的充气或放气,以使得挂车提升桥上升或者下落,其能够根据挂车空气弹簧的实时载荷数据,自动控制挂车提升桥的上升和下落,从而替代通过人工控制挂车提升桥上升或下落的方式,实现提升桥自动升降,使得提升桥控制过程更加智能,继而实现降低油耗、降低非满载状态下挂车轮胎的损耗。
