The popularity of electronic systems had increased in automobiles. A lot of ECUs, electronics sensors, bus are used in automobile systems which has made the system complex. Safety analysis should be done to ensure functional safety. IEC has introduced the standard, ISO 26262 for safety analysis of electrical/electronic/programmable systems in automobiles to reduce and control systematic faults. ISO 26262 give guidelines to define and follow the techniques strategically for the entire product life cycle of the vehicle. It does not explain how functional safety is done but it will guide us throughout the process. In this paper, we have analysed the Automatic Emergency Braking system as per the ISO 26262 guidelines. AEB is a significantly important active safety system which relies on electronic sensors, ECU and electronic actuators. The proper functioning of these electronic components could save the hazard from happening. We have determined the ASIL level, we determine safety goal and safety requirement, Fault Tree Analysis (FTA), Failure mode and Effect analysis. Also, we performed an HW safety analysis.
