Inertial measurement unit fault detection isolation reconfiguration using parity logic
摘要：
A method of implementing a fault-tolerant-avionic architecture in a vehicle includes using parity logic to monitor the functionality of at least three non-fault-tolerant inertial measurement units during a parity check and calculating a threshold from expected inertial measurement unit performance during a parity check. If a failure of an inertial measurement unit is detected based on the calculated threshold, then the method further includes identifying the failed inertial measurement units based on a direction of a parity vector in parity space. Each inertial measurement unit comprises at least one triad of sensors.
摘要（中）：

在车辆中实现容错航空电子体系结构的方法包括在奇偶校验期间使用奇偶校验逻辑来监视至少三个非容错惯性测量单元的功能，并且在期望的惯性测量单元性能期间计算阈值 奇偶校验 如果基于所计算的阈值检测到惯性测量单元的故障，则该方法还包括基于奇偶校验空间中的奇偶校验向量的方向来识别失效的惯性测量单元。 每个惯性测量单元包括至少一个三元组的传感器。
