Electrical and electronic systems have increased in the automotive industry with stronger regulations on fuel efficiency and safety, along with higher consumer demands for advanced technology. The increase in E/E systems has dramatically heightened the level of complexity in vehicle designs, which also resulted in higher rates of system malfunction. However, most of the automotive parts companies are using safety analysis techniques based on chain of events, such as HAZOP, FMEA and FTA. These methods can be insufficient in analyzing the potential failure of the component interaction that can be found in complicated control systems. This research aims to provide a safety analysis of the ISO 26262 concept, system, and software development phase applying STPA based on STAMP. A case study on the smart key system in vehicles is introduced, and the new method is compared to the other existing methods so as to demonstrate the effectiveness of this study. |
