Abstract: Based on ISO 26262 Road Vehicles Functional Safety,this paper takes the electric vehicle motor controller as the research object which determines the functional safety goals and the corresponding indicators and functional safety requirements through methods such as function identification,definition of the item under consideration,and hazard analysis and risk assessment.These results serve as the input for the subsequent detailed system design.
Key words: electric vehicle; motor controller; function safety; ISO 26262
