基于CTL模型和任务绩效的驾驶舱动态功能分配方法

Dynamic Function Allocation for Cockpit Based on CTL Model and Task Performance

飞机驾驶舱系统自动化水平提高的关键在于实现飞行任务的动态分配。为了提高动态功能分配的可靠性,提出用于实时估算飞行员脑力负荷的认知任务负荷(Cognitive Task Load,CTL)模型,将模型估算的飞行员脑力负荷与飞行任务绩效的测量结果相结合作为飞行任务动态功能分配的综合触发信息,飞机驾驶舱系统将综合触发信息经过模糊推理输出飞行任务自动化等级,实现飞机驾驶舱功能的动态分配。最后,通过试验验证了所提出方法的有效性。

The key to the improvement of the automation level of the aircraft cockpit system is to realize the dynamic allocation of the flight mission. In order to improve the reliability of the dynamic function allocation,this paper proposes a cognitive task load（CTL） model for real-time estimation of mental workload of pilots,and combines it with the measurement results of flight task performance as the integrated trigger information of the flight mission dynamic function allocation. Via fuzzy reasoning,the aircraft cockpit system outputs the level of flight task automation,realizes the dynamic function allocation of the cockpit function. Finally,the effectiveness of the proposed method is verified by experiments.
