Framework

“Software Update Management System (SUMS)”means a systematic approach that defines organizational processes and procedures for complying with the requirements for software update delivery pursuant to this Regulation. [UN-R156, Section 2.5]

SUMS provides a framework for implementing the necessary processes:
▪ Traceability and consistency of type-approved systems

▪ Unique identification of all initial and updated software

▪ Evaluation of whether software updates are relevant for type approval

▪ Identify interdependencies and verify compatibility

▪ Security (protecting the integrity and authenticity of software updates);

▪ Evaluating whether an update affects safety or safe driving

▪ Documentation of all of the above – and sharing of information with Certification Bodies (or OEMs in the case of suppliers)
