Safety Framework
Safety frameworks provide the requirements for developing electronic controls in passenger vehicles. The iso 26262 functional safety framework provides a process for mitigating risks from hardware failures and software errors. Adherence to the standard is mandatory for systems whose failure could result in life threatening situations.
Risk Classification
Hazard analysis and risk assessment are performed to determine the automotive safety integrity level required for each component. An iso 26262 functional safety plan defines the goals and the technical requirements for avoiding dangerous failures. Higher levels demand more rigorous testing and redundant architectures.
This system ensures that even if a part breaks, the vehicle remains in a controllable state.
Verification Process
Engineers conduct failure modes and effects analysis to identify potential weak points in the design. The iso 26262 functional safety standard requires documented proof that the safety goals have been met through simulation and physical testing. Software is audited for coding standards and structural coverage.
Independent assessors verify the results to ensure the development process was followed correctly.
Supplier Management
Responsibility for safety is shared across the entire manufacturing chain. The iso 26262 functional safety documentation includes a safety case that justifies why the system is fit for use on public roads.
