This paper proposes an ¡°Autonomous Vehicle Self-diagnosis System (AVSS) based on Random Forest and Loop-back ¡± that recovers the software error of the sensor based on loop-back and diagnoses the condition of a vehicle using the sensor data of the vehicle based on the random forest. The AVSS is consists of two modules. first, the Sensor Failure Recovery Module (SFRM) collects sensor data in real time and, if an abnormality occurs in the sensor, initializes and recovers the sensor. second, the Vehicle Diagnostic Random Forest Module (VDRF) generates a random forest model and diagnoses the overall condition of the vehicle using the generated random forest model. As a result, the AVSS's self-diagnosis time using neural network models was 101% faster than exisiting vehicle self-diagnosis. Therefor, because the AVSS can diagnose vehicle conditions faster and more accurately than exisiting self-diagnostic systems, it increases the reliability of vehicle safety. |
