Introduction
Demonstrator vehicles typically do not comply with functional safety standards mandatory for serial production vehicles. However, functional safety remains crucial for demonstrators. FEV.io has defined a simplified process to ensure safety in these applications.
Background
FEV.io was contracted by a European engine manufacturer to ensure the functional safety of a hydrogen-powered prototype combustion engine, intended for various applications such as excavators and gensets.
Approach
FEV.io applied its prototype functional safety process, which includes:
- Definition of the item (system boundary, function description)
- Hazard analysis
- Risk assessment and mitigation
- Establishment of traceability between features, hazards, and safety measures
- Verification of these measures
Impact
By applying FEV.io’s prototype safety processes, based on standards such as ISO 12100 and ISO 13849, we achieved:
- A sufficient level of functional safety for the prototype application
- Comprehensive documentation of the functional safety development
- Inclusion of UNECE R134 design requirements
