The invention provides an aircraft brake critical slip state recognition method and device, and belongs to the technical field of aircraft brake control. According to the aircraft speed, a left pilot brake instruction and a right pilot brake instruction, whether self-adaptive braking needs to be carried out or not is judged, and when self-adaptive braking needs to be carried out, a brake critical slip state mark LS is set to be 1; the slip rate of self-adaptive braking is calculated; and then the brake critical slip state is recognized based on the slip rate, aircraft brake control is carried out in the brake critical slip state, the purpose that the brake torque is equal to the ground combined torque is achieved, a brake control system is in the critical slip state, the brake capacity is fully exerted, and the brake efficiency is remarkably improved.

    本发明提供一种飞机刹车临界打滑状态识别方法及装置,属于飞机刹车控制技术领域,本发明根据飞机速度、左飞行员刹车指令、右飞行员刹车指令判断是否需要进行自适应刹车,并在需要进行自适应刹车时,将刹车临界打滑状态标志LS置1;计算自适应刹车的滑移率;之后基于滑移率识别刹车临界打滑状态,实现了在刹车临界打滑状态下进行飞机刹车控制,达到刹车力矩等于地面结合力矩的目的,使刹车控制系统处于临界打滑状态,刹车能力得到充分发挥,刹车效率显著提高。
