The invention relates to the technical field of multi-axle vehicles, and provides a suspension control method and system and a multi-axle vehicle. The suspension control method comprises the following steps: acquiring an airbag pressure value of an airbag in real time; comparing the airbag pressure value with a preset pressure value to obtain a pressure difference; controlling the air bag to be inflated or deflated according to the pressure difference until the pressure of air in the air bag is a preset pressure value. According to the suspension control method and system and the multi-axle vehicle suspension control method, the pressure value of the air bag is adjusted to the preset pressure value according to the change of the pressure in the air bag, so that the air bag can be always kept in the constant-pressure inflation or exhaust state, the method is simple, reliable and easy to implement, all axles in a vehicle device can bear loads in a balanced mode, and the situation that part of the bridges bear too large under severe or special working conditions is avoided and then the service life of related parts is prolonged.

    本申请涉及多轴车辆技术领域,提供悬架控制方法、系统和多轴车辆。该悬架控制方法包括:实时获取气囊的气囊压力值;比较气囊压力值与预定压力值,获取压力差;根据压力差控制气囊充气或排气至气囊内气体的压力为预定压力值。悬架控制方法、系统和多轴车辆悬架控制方法,通过根据气囊内的压力的变化来调节气囊的压力值至预定压力值,使得气囊能够始终保持恒定压力充气或排气状态,方法简单、可靠,易于实现,能够达到车辆装置中的各桥均衡承载,避免了在恶劣或特殊工况下部分桥承载过大,进而提高了相关零部件的使用寿命。
