GB 44496 is China’s first mandatory standard for automotive software upgrades, enforced alongside GB 44495 and GB 44497.
·Scope: M/N-category vehicles and ECU-equipped O-category vehicles with OTA/offline upgrades.
·Enforcement: New models from July 1, 2026; existing models by July 1, 2027.
2.Dual Certification Framework
·SUMS (Software Upgrade Management System): Organizational process audit (prerequisite for vehicle testing).
·VTA (Vehicle Type Approval): Real-vehicle technical compliance testing.
3.Step-by-Step Certification Process
Step 1: Gap Analysis & Preparation (3–6 Weeks)
Assess document systems, process execution, supply chain control, and technical gaps (signature, rollback, HMI).
Step 2: System Document Compilation & Trial Operation
·Software upgrade security policy (signed by top management).
·Organizational structure with clear roles (release approver, impact assessor).
·9 mandatory process procedures (version identification, target vehicle matching, type-approval assessment, etc.).
·Anti-tampering, verification, and emergency response documents.
Step 3: Apply for SUMS Audit
Qualified institutions: CAVC, CQC, CCAP. Submit application, business license, system documents, and upgrade records.
Step 4: SUMS On-Site Audit (2–3 Days)
Verify record integrity, change management, staff competency, and emergency preparedness. Correct non-conformities within 30–45 days.
Step 5: VTA Test Preparation
Confirm vehicle configuration, prepare technical documents, ensure sample functionality, and coordinate HMI/cloud environments.
Step 6: VTA Testing & Rectification (4–8 Weeks)
Test upgrade package security, RxSWIN identification, user notification/consent, power protection, door unlock, interruption rollback, and result notification.
Step 7: CCC Certification Submission
Submit SUMS certificate, VTA report, technical parameters, and consistency plan to obtain CCC certification with GB 44496 compliance.
Total cycle: 5–8 months (smooth); 12+ months (major revisions).
4.Certificate Validity & Post-Certification Obligations
·Certificate validity: ~5 years (per CCC rules).
·Annual surveillance audits: Required to maintain validity.
·Record retention: 10 years post model discontinuation.
·Change management: Re-assessment for major architecture/software changes.
