초록
In this study, the failure analysis was conducted and improved on the case where the movement of the tracked vehicle was restricted due to a failure of the inertial navigation system. This phenomenon is caused by the failure to detect the abnormal operation of the accelerometer in the self-diagnosis mode of the accelerometer and IMU of the INS. Therefore, a error checking logic in the self-diagnosis mode was added to enable self-diagnosis in the accelerometer and IMU. The improved inertial navigation system was confirmed to be normal through a system interlocking test. The improved self-diagnosis mode of the INS is expected to contribute to the improvement of equipment’s ability to maintain and operate by letting the military quickly identify the failure.
