The invention discloses a multi-agent-based interconnected air suspension cooperative control system and method. The method comprises the steps of obtaining the internal air pressure of an air spring through an air pressure sensor after a whole vehicle is excited by a road surface, obtaining the sprung and unsprung mass velocities of the vehicle through a speed sensor, transmitting the information to a central control unit, and the target suspension force at the four-wheel position of the vehicle is calculated by the central control unit. A damping suspension force output mechanism, an interconnection suspension force output mechanism and a vehicle height suspension force output mechanism are regarded as three deliberate intelligent agents, a cooperative control strategy of the three intelligent agents is formulated according to the magnitude of the needed suspension force and the respective action cost, the target suspension force of the whole vehicle is distributed and output, and the output suspension force acts on the whole vehicle in a feedback mode. The problems that three suspension force output mechanisms are high in coupling degree and difficult to cooperate can be effectively solved, and meanwhile energy consumption of the system caused by too frequent opening and closing of electromagnetic valves is reduced.

    本发明公开了一种基于多智能体的互联空气悬架协同控制系统及控制方法,在整车受到路面激励后利用气压传感器获取空气弹簧的内部气压,利用速度传感器获取车辆的簧上及簧下质量速度,将上述信息发送至中央控制单元,经中央控制单元计算得到车辆四轮位置处的目标悬架力。将阻尼、互联、车高三个悬架力的输出机构视为三个慎思型的智能体并结合所需悬架力的大小和各自的动作成本制定三者的协同控制策略对整车的目标悬架力进行分配输出,输出的悬架力将反馈作用于整车。本发明可有效解决三个悬架力输出机构耦合度高,难以协同的问题,同时降低系统因电磁阀开闭过于频繁产生的能耗。
