ISO 26262- ＂Road vehicles- Functional Safety＂ is widely regarded as the ＂state-of-the-art＂ safety standard exclusively for the automotive industry that proactively addresses potential accidents due to systematic and random failures in the electrical/electronic system. The standard essentially encompasses the entire lifecycle of a product starting from conception, through development process, production, operation, service and the eventual decommissioning. In particular, a critical aspect of the safety philosophy championed by the standard is the specification of safety requirements prior to the start of each development phase of the product. ISO 26262 specifically defines the hierarchical structure of safety requirements and the corresponding properties they should inherit. In general, the practice of requirement engineering in Taiwan's automotive industry is often of mediocre quality. Hence this paper attempts to provide some reference examples so as to encourage experience sharing on the specification of safety requirements in practice. The paper focuses on the derivation of software safety requirements related to a motor control system intended for a pure electric vehicle.
