Bibliography

Specifies common methods of providing passive safety that may be adopted to suit individual vehicle requirements. Ascertains the characteristics of reference obstacle models for use in the design collision scenarios. Also describes the requirements for demonstrating that the passive safety objectives have been achieved by comparison with existing proven designs, numerical simulation, component or full-size tests, or a combination of all these methods.
