초록
An implementation of OSEK NM, a network management protocol for automotive embedded systems, has been defined. In this experiment, the NM ID of each ECU of the vehicle is reverse-engineered when the vehicle is parked with a discharged battery, and the power management status and error status of each ECU and node are identified through NM ID OPCODE analysis, Sleep status, and Wake-up status, LIMP HOME status, were analyzed. After analyzing the NM OPCODE to find the faulty ECU, remove the cause of the failure and analyze the sleep mode entry state.In order to prevent the vehicle battery from being discharged, additional research is needed on how to enter the forced sleep mode when a failure not related to vehicle security occurs.
