The invention belongs to the field of pneumatic brake control, and discloses an air brake braking method of an unmanned drive-by-wire chassis and a related system, which monitor the state of a vehicle in real time and make a response in time by continuously collecting vehicle load data, vehicle speed data and pressure data of an air brake. The expected deceleration is obtained according to the opening degree of the brake pedal and compared with the current vehicle speed, the deceleration requirement of the vehicle is accurately judged, and therefore accurate brake control is achieved. And a proportional valve adjusting instruction is generated according to the comparison result, so that the braking force can be adaptively adjusted according to the actual situation to adapt to different driving conditions and road conditions. By adjusting the front axle proportional valve and the rear axle proportional valve, the braking force distribution of the vehicle can be balanced, the braking stability and stability are improved, and the sideslip and slip risks of the vehicle are reduced. Through precise braking control, waste of braking energy can be effectively reduced, the energy utilization efficiency of the vehicle is improved, and therefore the purposes of energy conservation and environmental protection are achieved.

    本发明属于气动制动控制领域,公开了一种无人线控底盘的气刹制动方法及相关系统,本发明通过持续采集车辆载荷数据、车速数据以及气刹的压力数据,实时监测车辆状态,及时做出响应。根据刹车踏板的开度获取期望减速度,结合当前车速进行对比,准确判断车辆的减速需求,从而实现精准的制动控制。根据对比结果生成比例阀调节指令,使得制动力的调节能够根据实际情况进行自适应调整,适应不同的驾驶条件和路况。本发明通过调整前桥比例阀和后桥比例阀,能够平衡车辆的制动力分配,提高制动的平稳性和稳定性,减少车辆的侧滑和打滑风险。本发明通过精准的制动控制,能够有效减少制动能量的浪费,提高车辆的能源利用效率,从而达到节能环保的目的。
