The invention relates to a differential brake control method and an aircraft ground direction control system, which can reliably avoid the danger that an aircraft laterally rushes out of a runway at a high speed even when crosswind occurs or pedals are blocked at an unfavorable position. Through execution of the differential brake control method, when a pedal assembly has pedal jamming/failure, a brake pedal instruction of differential brake is switched to control deflection of a target object, the current angle of the pedal assembly is obtained, and the current angle and a pedal deflection angle converted based on the brake pedal instruction are combined to obtain an actual pedal deflection angle; obtaining a target object angle corresponding to the current angle of the pedal assembly according to a preset mapping relation, and determining a function relation between the pedal deflection angle and the target object deflection angle based on ground direction control amplitude limiting logic and the current parameters of the airplane, a target object deflection angle target value corresponding to the pedal position under the ground direction control amplitude limiting logic is obtained, and deflection of the target object is controlled in a servo mode according to the target object deflection angle target value.

    一种差动刹车控制方法和飞机地面方向控制系统,即使在侧风或是脚蹬卡阻在不利位置时也能可靠地避免飞机高速侧向冲出跑道的危险。通过差动刹车控制方法的执行,在对脚蹬组件出现脚蹬卡阻/失效时切换为利用差动刹车的刹车踏板指令来控制目标对象的偏转,其中,获取脚蹬组件当前角度并与基于刹车踏板指令换算来的脚蹬偏转角一起,获得脚蹬实际偏转角度,根据预设的映射关系,获取与脚蹬组件当前角度对应的目标对象角度,基于地面方向控制限幅逻辑和飞机当前参数,确定脚蹬偏转角度与目标对象偏转角度的函数关系,得出在地面方向控制限幅逻辑下与脚蹬位置对应的目标对象偏转角度目标值,根据目标对象偏转角度目标值伺服控制目标对象的偏转。
