GB 44496 submission materials rely on two interconnected pillars: system assurance documents and vehicle technical documents.

1.System Assurance Documents

·Governing documents: Security policy, organizational chart with clear roles.

·Full-lifecycle process documents: Risk assessment, user consent records, supply chain management, internal audit reports.

·Record retention: 10-year storage post model discontinuation (electronic archiving recommended).

2.Vehicle Technical Documents

-Basic technical descriptions: Upgrade architecture, ECU list, network topology.

-Technical verification evidence:

·User notification/consent HMI proof.

·Power protection threshold data.

·Upgrade package signature & verification mechanisms.

·Full rollback logic for interruptions.

·Door unlock protection test evidence.

·Unique RxSWIN verification.

-Official VTA test report (mandatory for type approval).

3.Document Audit Focus

·Completeness: No missing mandatory documents/evidence.

·Consistency: System documents match actual records; technical documents match vehicle performance.

·Specificity: Tailored content (not generic templates) to avoid extended reviews.

4.Validity & Continuous Compliance

·Certificate validity: ~5 years with annual surveillance.

·Pre-upgrade type-approval assessment: Required for safety/emission-affecting changes.

·Major model changes: Re-testing/assessment mandatory.

·Standard amendments: Timely adaptation within transition periods.
